The 52-Point Gap Hiding in Every Jersey Sire Catalog in Canada

Wednesday, May 6th, 2026

Canada’s top ten Jersey sires average 99th-percentile LPI and 47th-percentile Reproduction. That 52-point gap sired 29% of 2025 registrations — and never shows up on a single catalog page.

Jersey Canada’s record registration year produced a top ten sire group with elite LPI and conformation. Yet a look under the hood, and the Reproduction and Milkability subindexes tell a very different story for the future cows filling Canadian barns.

When I sat down in March 2026 with Jersey Canada’s 2025 registration data and Lactanet’s December 2025 genetic evaluations, I expected to see what the catalog pages were already shouting. Record registrations, up 9.74% over the previous high. Ten sires averaging Lifetime Performance Index (LPI) at the 99th percentile. Conformation at the 97th. Every bull A2A2. On paper, the Canadian Jerseys looked like they were winning on every front.

Then I pulled the LPI subindex profile on that same top ten group. The Reproduction Index (RI) across those bulls averaged the 47th percentile — below breed average. Five of ten fell below the median for fertility. The Milkability Index (MI), Lactanet’s subindex covering milking speed, temperament, and mammary milking traits, sat at the 34th percentile. And the Health & Welfare Index (HWI) — the one that captures Metabolic Disease Resistance, Mastitis Resistance, and Cystic Ovaries — averaged just the 59th percentile, with four bulls below the 50th.

Let me say this plainly: neither the breed associations nor the A.I. companies are publishing or promoting subindexes, and very little has been published on understanding or using them. After six decades of breeding cattle and working on dairy cattle improvement — including the original Dollar Difference Formula and Holstein Canada’s Type Classification overhaul in the 1980s — I’m still pushing the industry to look past the numbers it celebrates and toward the economically important ones it quietly ignores.

That’s not breeders failing to read the fine print. That’s a system that never printed it.

What Do Canada’s Top 10 Jersey Sires Actually Look Like Genetically?

Let’s start with which sires are actually driving the breed.

The ten bulls leading Jersey Canada’s 2025 registrations — ToBeFamous and Ghost tied at No. 1, followed by Victorious, Skyfall, Xenial, Artemis, Goldorak, Honeymoon, Cinnamon, and Tekashi — averaging 402 registered daughters each. Together, they sired 29% of all Jersey registrations in Canada that year. Eight of the ten were genomic sires when used, and those eight alone account for 81% of the group’s registered daughters.

When eight genomic bulls shape roughly one in four registered calves in a country, their genetic profile isn’t just interesting. It’s the trajectory of the breed.

Here’s how the Lactanet December 2025 evaluations stack up for that top ten:

IndexAveragePercentile RankRangeBulls Below 50th
LPI1,91899th39th–99th1 of 10
Pro$$1,542~97th——
Production Index (PI)—81st56th–99th0 of 10

Health & Welfare (HWI)—59th17th–88th4 of 10
Reproduction (RI)—47th19th–84th5 of 10
Milkability (MI)—34th2nd–90th5 of 10

Protein %+0.16%—0.07–0.310 of 10
Conformation (CONF)+11.497th−2 to +181 of 10

The gap between the 99th-percentile LPI and the 47th-percentile RI — 52 percentile points — might be the most revealing number in this dataset. It also never shows up on a sire card.

Why Don’t Breeders See the Fertility and Milkability Gap?

The short version: nothing in the current sire selection pipeline forces RI, HWI, or MI onto the table when you’re actually ordering semen.

Fat percentage is loud. When a bull adds +0.83%F — the high end of this top ten’s range — the economic reward shows up on every milk settlement. The A2A2 and BB casein story works the same way: processors put a premium on paper, breeders respond, and by 2025, the breed hit 100% A2A2 and 90% BB kappa-casein among its most-used sires. That’s the market signal doing exactly what it’s supposed to do.

Fertility costs are quiet. When a cow takes an extra cycle or two to settle, the penalty spreads across the vet bill, the semen line, the replacement purchase, and a longer calving interval that drags down lifetime milk and drives up lifetime days dry. None of those line items show up with a bold “this is what 47th-percentile RI genetics cost you this month” stamped on them.

Timed AI programs like Double-Ovsynch and Presynch-Ovsynch deepen the blind spot. They override a cow’s own biology, delivering conception rates that hide genetic fertility deficits. The protocol works — but it costs more to maintain with every percentile point of genetic fertility you give away. More shots. Tighter labour timing. More resynchronization cycles.

The Milkability Index gap tells its own story. MI combines milking speed, temperament, and milking-related mammary traits — exactly the traits that determine how quickly and smoothly cows move through a parlour or a robot box. A 34th-percentile MI average means the daughters of the breed’s most popular sires are, on balance, below average for the traits that drive milking efficiency and robot throughput. That’s real money in labour and robot capacity, especially as more Canadian herds adopt automated milking.

Fat Gains Up, Fertility Drifting: Five Years of Jersey Genetic Trends

Zoom out to the five-year trend for the top ten registration sires from 2020 to 2025, and the selection pattern comes into focus:

TraitAnnual Gain (Top 10 Registration Sires, 2020–2025)
LPI+44 points/year
Pro$+$99/year
Milk Volume−25 kgs/year
Fat Yield+3 kgs/year
Fat %+0.05%/year
Protein Yield+1 kg/year
Protein %+0.03%/year
Conformation+0.8/year
Mammary System+0.8/year
Dairy Strength+0.90/year
Feet & Legs+0.75/year
Rump+0.66/year
Inbreeding−0.28%/year

Milk volume is deliberately sliding while fat and protein percentages climb. That’s component pricing at work, and breeders are delivering exactly what processors reward.

What’s missing in that trend table are equivalent progress numbers for RI, HWI, or MI. The traits everyone tracks, publishes, and celebrates are the ones getting selected. The ones buried in PDF footnotes are drifting. The 47th-percentile RI average is a pretty good hint of which direction.

On the positive side, the inbreeding story is exactly what you’d hope to see. The average for the top ten drops from 9.77% in 2020 to 8.10% in 2025 — a reduction of 0.28% per year, with seven of ten bulls sitting under 9.0%. That proves something important: Canadian Jersey breeders can manage a trait that isn’t on the milk cheque when the industry makes it visible and gives them tools. It’s fair to ask why the same thing hasn’t happened for reproduction, health, and milkability yet.

The Barn Math Behind 47th-Percentile Fertility

Here’s where you can feel it in your own numbers.

A 200-cow Jersey herd turning over 35% annually needs about 70 replacement heifers a year. That’s just barn math: 200 × 0.35 = 70.

On the cost side, U.S. dairy replacement prices hit about $3,010 per head in July 2025, up 164% from the 2019 bottom of around $1,140, with top heifers bringing $4,000 or more in some auction barns. In Ontario, replacement heifers over 900 lbs were selling around $326–$328 per hundredweight at recent auctions — not the same absolute price, but the direction of travel is similar.

Now layer in genetics. If below-average RI bulls add even one extra service per conception across your dairy-bred matings, that’s more semen, more time open, and more risk that cows fall out of the dairy pipeline and into beef because they didn’t settle. It’s not just a $30–$50 sexed semen straw that didn’t stick. It’s a heifer that never existed, and a cow that probably gets bred to beef because everyone’s tired of missing her.

My read of the Production Index adds another twist. The PI averages the 81st percentile across the top ten — good, but notably lower than the LPI at the 99th and the LTI at the 91st.. In other words, the composite LPI for these bulls is being carried more by longevity and type than by yield. That raises a fair question: how much of that 1,918-point LPI reflects real lifetime profitability, and how much is the formula letting strong CONF and LTI paper override weak RI and MI?

Does 97th-Percentile Conformation Actually Drive Jersey Profitability?

On paper, this top ten group is a type breeder’s dream. The average conformation score sits at +11.4 — the 97th percentile — with a range from −2 to +18. Mammary system averages +8.9. Feet and legs average +8.5. Those are big numbers.

The real question is what those numbers actually buy you.

Canadian work from Agriculture and Agri-Food Canada on longevity found that udder depth and milking ease accounted for 84% of the total contribution of type traits to functional longevity, and that rear teat placement, udder depth, and udder texture had a significant influence on functional survival. Cows with tight, well-attached udders stayed in the herd longer.

Alcantara, Baes, de Oliveira Junior, and Schenkel (2022), in the Canadian Journal of Animal Science, put hard-dollar values on the type traits involved. Analyzing 9,351 proven Holstein bulls, they found heel depth had the strongest positive effect on Pro$ of any conformation trait, at +$79.13 per unit RBV increase.

In plain terms: heel depth pays you; extreme body depth costs you.

That same paper showed dairy capacity (especially body length) was also positive, at +$59.00 per unit RBV. More capacious, angular cows tended to stay productive longer. But body depth told the other side of the story: it had the largest negative effect on Pro$ at –$61.95 per unit RBV because deeper-bodied cows ate more, tended to lose condition more quickly after calving, and showed poorer fertility in later lactations.

The problem is that composite CONF rewards all of it. Stature, angularity, body capacity, and dairy character are assigned the same number as functional mammary and feet-and-legs traits. So, a bull could rank in the 97th percentile for CONF largely on height and style, while another sits in the 72nd percentile with rock-solid udders and feet. The composite score doesn’t tell you which one actually puts more money in your pocket over five lactations. And neither does the catalog page.

What Would a Balanced Jersey Sire Stack Look Like in 2026?

The 2025 data doesn’t say you need to blow up your sire list and start over. It says you need an index floor when selecting sires. And you need it on traits and subindexes where no one has put one to date.

  • Set a hard RI minimum at the 50th percentile for every bull in your stack. That’s not aggressive — it just means refusing to use sires whose daughters carry below-average fertility genetics. Apply this filter to the current top ten, and five of the ten drop out immediately. If you actually want to improve fertility, not just stop the slide, aim for RI in the 65th percentile or better. This month, pull the Lactanet subindex breakdown for every sire in your current mating plan. If any bull sits below the 50th-percentile for RI, flag him for replacement or for use only on your most fertile cows. 
  • Give HWI a seat at the table. The top ten average just the 59th percentile for the Health & Welfare Index, with four bulls below the median. HWI is where Metabolic Disease Resistance, Mastitis Resistance, and Cystic Ovaries live in the modernized LPI. A 55th percentile floor keeps you from actively weakening your health genetics; 65th and up start building a real health advantage into your replacements. 
  • Use MI as a robot and labour filter. With a 34th-percentile average, MI is the weakest subindex for this top ten group. Suppose you’re milking with robots — or thinking about it — milking speed, temperament, and teat placement matter just as much as litres. Even in a parlour, slow or difficult milkers chew up labour. Set your own MI floor at the 45th percentile, so you’re not selecting against milkability. In a robot environment, you might want a higher percentile. 
  • Cap CONF expectations and target the right pieces. Instead of chasing 97th-percentile CONF across your whole stack, think in a 65th–80th percentile window and focus on mammary and feet-and-legs sub-scores. The Alcantara et al. work backs this up: heel depth and dairy capacity drive Pro$, while body depth drags it down. Select accordingly. 
  • Use high-LPI/low-RI sires as specialty tools, not blanket-herd bulls. A bull sitting at 99th-percentile LPI with poor subindex scores might still earn a place, on the 15–20% of cows with outstanding fertility and health backgrounds where you can safely chase an outcross, special pedigree, or type shot. He shouldn’t be breeding 80% of the herd. 
  • Before your fall semen order (90-day action), write a simple sire selection protocol. One page. Minimum RI and HWI percentiles. Plus a desired MI floor. Target range for CONF with mammary and feet/legs priorities. Share it with your AI rep and your genetic advisor. If they can’t work within it, that’s a data point too. 
  • By spring 2027 (365-day action), pull services-per-conception data by sire group from your own herd records. That’s where you’ll see RI genetics and timed AI protocols separate. A bull who looks fine on paper but needs 3.2 services per conception in your barn is telling you something your sire catalog won’t. 

What This Means for Your Operation

You don’t have to be running a big registered show string for this to matter. If you’re milking Jerseys and buying semen in Canada, you’re already living with the top ten bulls’ subindex profile. The only question is whether you’re steering it or just going along for the ride.

  • Run the subindex numbers on your current sire stack. Pull RI, HWI, and MI for every active bull you’re using. Calculate the weighted averages across your stack. If RI or HWI sits below the 50th percentile, you’ve quantified your genetic risk for fertility and health.
  • Decide what you’re actually willing to tolerate. A 47th-percentile RI average is what you get if you follow the registration leaderboard without asking questions. The minute you set a hard floor — even just at the 50th — you’re back in control.
  • Look at your conformation priorities through an economic lens. How much of your type selection pressure is going into the mammary system and feet/legs, and how much is chasing body depth and stature that the research says doesn’t pay? Adjust your eye accordingly.
  • If you’re running robots, treat MI as a non-negotiable. A 34th-percentile MI stack is basically selecting against robot efficiency. Put a line in the sand. Then ask yourself how many of your current sires clear it.
  • Double-check your replacement economics. On your own numbers, what does it cost to buy a bred Jersey heifer, with profit potential, right now? What’s your actual replacement rate? How much room do you have to play with fertility genetics before you start buying more herd replacements than you’d like?
  • Ask your AI rep better questions. Before you talk pedigrees or price, start with: “What are the RI, HWI, and MI percentiles on your top five Jersey sires for my herd?” If the answers come quickly — with printed subindex charts — you’re dealing with someone who’s reading the full proof sheet. If not, you’ve learned something about whose problems are being solved by that catalog page.

Key Takeaways

  • If half of the ten most-used Jersey sires in Canada sit below breed average for reproduction, the problem isn’t that breeders don’t care about fertility — it’s that the system never put RI, HWI, and MI on equal footing with LPI and CONF. I’ve been making that argument in one form or another for years: the numbers the industry promotes are the numbers that get selected. The numbers it buries get ignored. 
  • The A2A2 success story proves breeders respond fast when the signal is clear. Processors put a premium on paper; within a few proof runs, the top ten registration bulls went 100% A2A2 and 90% BB. There’s no reason the same can’t happen for RI and MI once those numbers get the same font size in sire marketing and herd discussions. 
  • The inbreeding trajectory shows it can be done. Dropping from 9.77% to 8.10% in five years didn’t happen by accident. It happened because inbreeding became visible and manageable. RI, HWI, and MI are sitting where inbreeding was a decade ago — important, but underused. 
  • The Milkability Index might be the quietest and most expensive number on the page for robot herds. A 34th-percentile MI stack means you’re effectively selecting against milking speed and temperament in a system where every extra minute per cow at the robot is lost throughput. That’s not a small leak. 
  • If you can write your sire selection protocol on one page — with hard subindex floors and a clear role for each bull — you’re ahead of most of the industry. The herds that do that over the next five years will be the ones with the replacements, the robot-friendly udders, and the health genetics that give them room to experiment elsewhere.

Five years from now, the real test of whether this analysis mattered won’t be on a Bullvine page. It’ll be in your own Lactanet login when you pull up your 2030 sire stack and see where your RI, HWI, and MI averages landed. Pull that same screen up tonight. What’s your average RI percentile — and are you honestly okay living with that number for the next five years?

Powerhouse Up 119, Rozline Down 626: The April 2026 Holstein Proof Reset on Your Sire List

Wednesday, April 8th, 2026

One bull climbed 119 TPI, another lost 626 Pro$, and a few “safe” favorites quietly slid out of the money.

The proofs landed on a cold April morning, and by the time the printer stopped spitting out pages, one thing was obvious at a 450‑cow Wisconsin freestall herd we chatted with: the semen in their tank no longer matched the numbers on the sheets. Powerhouse had just picked up 119 TPI under the new US protein formula, while Rozline had shed 626 Pro$ in Canada. 

Same bulls. Same daughters milking in their barns. But in one proof run, their jobs changed. This is the story of how that happened — and what you can realistically do in the next 30 days so you’re not breeding April 2026 calves with December 2025 math. 

“Did We Just Spend Our Semen Budget on Yesterday’s Bulls?”

That Wisconsin herd had done what a lot of us do. The winter order leaned into bulls that felt like “safe bets”: Peak Powerhouse‑ET on the US side for TPI and Siemers Renegade Rozline‑ET for Canadian Pro$ and LPI with type. 

On paper, in December, that plan made sense. Powerhouse sat at 3329 TPI, Rozline at 2664 Pro$ and 3947 LPI, and both were plastered all over catalog covers. 

Then April hit. Holstein USA rolled out the TPI 2026 formula with 24% weight on PTA Protein and 14% on PTA Fat, shifting five percentage points of production weight from fat to protein.  That single change lifted Powerhouse from 3329 to 3448 TPI (+119) and knocked fat‑heavy bulls like SDG Cap Garza‑ET down –125 TPI (3464 → 3339). 

North of the border, Canada’s April 2026 run trimmed the Pro$ ceiling by roughly 200–250 points for most front‑end bulls — and a lot more for Rozline. Progenesis Pattern‑ET held #1 Pro$ at 2974, but still dropped –237 Pro$; Denovo 16034 Cabo‑ET fell –231 Pro$ to 2877. Rozline took the biggest hit, sliding from 2664 to 2038 Pro$ (–626) and from 3947 to 3810 LPI (–137), dropping from #1 to #9 LPI.

The proofs didn’t change how that breeder felt about the daughters. They did change how comfortable he was betting big semen checks on those bulls for the next calf crop.

One Global Run, Eight Different Messages

The April 2026 Holstein proof run isn’t one neat headline. It’s eight different proof systems pulling on the same straw box in their own way. Here’s the short tour before we get into what you do about it in your herd or ET program.

Holstein USA’s TPI 2026 production slice — 24P / 14F — quietly moved real money. 

  • Powerhouse: +119 TPI (3329 → 3448) on the same daughters, thanks to 92 Pro vs 113 Fat and big milk. 
  • Garza: –125 TPI (3464 → 3339) as his extreme fat profile became less valuable inside the index, even though his cows still fill the fat tank. 

On the genomic side, the signal is just how tight and volatile the very top has become:

  • All 10 bulls in the April 2026 genomic TPI top 10 are new names compared with December. 
  • The band from Aurora Gs Woodford‑ET at 3565 TPI down to Welcome Gustavsson‑ET at 3528 is only 37 points wide. 

The “shape” of a winning genomic TPI bull is clear — high milk, strong protein, good health, functional type — but the exact names at the top are going to churn.

In Canada, April 2026 was less about formula changes and more about level resets and the re-pricing of some favorites. 

  • Pattern: 3211 → 2974 Pro$ (–237), still #1 Pro$.
  • Cabo: 3108 → 2877 Pro$ (–231), still #2 Pro$. 
  • Winstar Graziano‑ET: 3099 → 2655 Pro$ (–444), sliding from #3 to #81. 
  • Rozline: 2664 → 2038 Pro$ (–626) and 3947 → 3810 LPI (–137), dropping to #9 LPI. 

Rozline’s April profile — 852 Milk, 85 Fat, 52 Protein, 0.47F, 0.18P, 16 Conf, MS 9, FL 9, DS 13 — reads like a type and component bull now, not a Pro$ anchor.  Pattern and Cabo still carry the income banner, but the gap between them and the next tier is smaller.

UK: Zero Overlap Between PLI and Type Merit

The UK’s April 2026 proof run draws a hard line between profit index and type. 

  • Denovo 22750 Lorenzo is #1 genomic PLI at 874, but carries –0.21 Type Merit with negatives on mammary and legs. 
  • 0 bulls are both top‑10 for PLI and top‑100 for TM. 

That doesn’t mean you can’t have reasonable type and profit at the same time. It just means the bulls that manage it are rarer:

  • Trophy: 769 PLI, 2.09 TM. 
  • Leaninghouse Taos: 613 PLI, 1.98 TM, 2.42 LF — PLI plus legs and feet that classifiers actually like. 

If you’re breeding UK‑aligned, April spells out a simple trade‑off: pure PLI rockets vs. those handful of bulls that keep both the milk cheque and the classifier roughly happy.

Switzerland: 1500 Is the New 1600 on ISET

Switzerland’s April 2026 Holstein ISET reset is a big story in a small country. The standard deviation change and swap from SCC to Mastitis Resistance mean 1500 ISET is more like the old 1600. 

  • Progenesis Torchlight: 1519 ISET, 1954 kg Milk, 130 kg Fat, 88 kg Protein, plus strong Mastitis Resistance and good health — a classic high‑ISET production bull. 
  • DG Caarma: 1482 ISET, 2212 kg Milk, 153 kg IPL, but fertility 98 and temperament 92 — he’ll put a lot of milk in the tank if your management can handle the extra temperament and fertility work. 
  • Beautyman took one of the bigger hits, dropping –159 ISET and sliding out of the top 20. 

The Swiss signal is clear: ISET now pays even more attention to cow health and mastitis, and you need to read bulls like Caarma through that lens before you chase their ISET number.

Netherlands and Germany: Longevity vs Lactation, Calm at the Top

In the Netherlands, NVI continues to favor cattle that stick around. 

  • Rise Up Real: +58 NVI to 468 NVI, now genomic #1 BW, with 614 INET but a huge Lvd 1084 — he’s built to live. 
  • Genosource Mystro: 431 NVI, but 881 INET, the highest in the top 10, with Lvd 751, the lowest longevity score in that group. 

On proven NVI, Genosource Captain added +74 NVI to land at 363 NVI and proven #2, reinforcing that his daughters aren’t just flash‑in‑the‑pan.

In Germany, the Interbull BW RZG genomic top 10 is almost too calm. 

  • Connect stays at 167 RZG, unchanged from December. 
  • The next nine bulls all sit between 161 and 163 RZG, and all ten are returning genomic bulls. 
  • Under the hood, pedigrees are heavily saturated with RealSyn and Rome; at least half of the pack traces through those sires. 

If you’re leaning on German RZG genomics, the risk isn’t that your bull drops 10 RZG. It’s that you wake up in three years and realize half your best heifers are RealSyn/Rome granddaughters, no matter which catalog you bought from.

Italy and Scandinavia: Proven Catching Genomics, VH Wall

In Italy, April 2026 gPFT was the run where some proven sires finally caught their genomic kids. 

  • Crisalis RF climbed by 67 gPFT to 5,247. 
  • His son Boero came in proven at 5162 gPFT, roughly +230 points above his old genomic call. 
  • Overall, the domestic proven gPFT top‑10 average jumped from 4934 to 5087 (+153), and half the list is new.

In Scandinavia, NTM is where the robots and the Viking genetics program shake hands. 

  • Peak Rainow‑ET slipped from 42 to 40 NTM but still holds proven #1. 
  • Fugleman climbed from 35 to 38 NTM, with better yield, udder health, claw health, and confirmed milkability at 126. 
  • On the genomic side, VH now owns 21 of the top 30 NTM slots. 

For a robot herd in Denmark or Sweden, that’s good news and a warning in the same sentence: plenty of high‑NTM options, but you can’t just buy “the top” and expect to stay out of a VH wall.

How Noisy Is “#1” This Run — and Should You Still Pay for It?

When you line all these lists up, the most important thing isn’t who’s #1. It’s how tight the bands are and how fast the names change. 

  • USA genomic TPI: 10/10 new bulls, 37‑point band (3565–3528). 
  • UK genomic PLI: roughly 70% turnover in the PLI top 10, 58‑point band from Lorenzo at 874 to the #10 bull at 816. 
  • Swiss ISET: 40% new bulls in the top 10 and only 47 points from Torchlight at 1519 down to the #10 bull at 1472. 
  • Dutch genomic NVI BW: only 1 new entrant, but the band still lifted and compressed to 468–424 NVI. 
  • German RZG: 0 turnover and a 6‑point band (167–161 RZG). 

At that point, paying a premium just because a bull is “#1” is more about marketing than genetics. It can still be fun. It just shouldn’t be the backbone of your breeding plan.

For practical breeding decisions, the takeaway is simple:

  • Treat that whole top genomic band as one group of bulls with a similar job description — high milk and protein, or high NVI longevity, or high ISET — not as ten different universes. 
  • Use “#1” as a tie‑breaker only after you’re happy with trait shape, health, and pedigree.

If the only reason a bull is on your short list is “He’s #1 this run,” this is the year to rethink that.

The Quiet Risk in Your Straw Box: Bloodline Stacking Across Borders

As the Wisconsin breeder flipped through the April results, another pattern popped up: the same sire families showed up over and over again, even though he was buying semen from three studs and four countries. 

  • Captain and his sons anchor US proven TPI lists, appear in Dutch NVI pedigrees, and show up behind Swiss and Italian bulls. 
  • Parfect/Renegade lines are written all over Canadian LPI and Pro$, and they feed into UK PLI/TM pedigrees. 
  • Gameday/Hadley/Troy show up repeatedly in Switzerland: five of the ISET top 15 have Gameday as maternal grandsire, with Hadley and Troy siring multiple leaders. 
  • Gladius/Vivify lines dominate Italy’s domestic and foreign gPFT lists, with Gladius responsible for four of the top‑10 positions across those lists. 
  • CRV Delta holds 5 of 10 black‑and‑white and 6 of 10 red‑and‑white genomic NVI spots in the Netherlands. 
  • VH sires (Viking Holstein) own 21 of the top 30 genomic NTM bulls. 
  • RealSyn/Rome pedigrees sit under at least half of Germany’s BW RZG genomic top 10. 

On the farm’s scribbled sire list, that looked like this: about 15% Captain sons, another 10–15% Parfect/Renegade line, and a big chunk of Swiss and Dutch bulls that quietly had Gameday, RealSyn, or Gladius as sire or grandsire.

Technically, he was “diversified.” Practically, he was a couple of sire families away from painting himself into a corner. The daughters won’t care which logo was on the straw. They’ll know who their grandsires are.

A Simple Micro Barn‑Math Check: When Does a 200‑Point Drop Actually Hurt?

One question that keeps coming up as breeders read about Rozline’s –626 Pro$ and Pattern’s –237 Pro$ is, “Okay, but what does that actually mean for my milk cheque?” 

Here’s a simple, illustrative way to think about it using Canadian Pro$:

  • Bull A: 3000 Pro$ in December, 2750 Pro$ in April — a 250 Pro$ move. 
  • Bull B: 3000 Pro$ in both runs — steady.

If you use each bull on 100 cows this year, that 250‑point difference represents about $250 per daughter in expected lifetime net profit on the Pro$ scale, based on Canadian assumptions for components, culling, and longevity. Over roughly three lactations, you’re looking at about $25,000 of projected value difference per 100 matings between those two bulls.

It’s not a cheque you cash in one year, and your herd’s actual numbers will run a little higher or lower. But it’s enough that you shouldn’t keep calling a bull your “Pro$ anchor” if his index just moved 250 points in the wrong direction.

The same logic applies in other systems — whether it’s NM$, INET, gPFT, or NTM — even if the dollars and assumptions are different. A one‑run swing of 200–250 index points is not background noise.

Where Do the Bulls Actually Sit Now?

If we strip the marketing off and look at how their jobs changed, a few bulls land in pretty clear buckets after April 2026. 

Formula winners — bulls the system likes more now than it did in December, without them adding a single daughter:

  • Powerhouse (USA)
    • +119 TPI to 3448 TPI under TPI 2026, with big milk and a protein‑leaning CFP profile. 
  • Woodford, Jitters, Sabotage (USA genomics)
    • Woodford: 3565 TPI, 1296 NM with roughly 1498 Milk, 142 Fat, 120 Protein, and strong health. 
    • Jitters: 3552 TPI, 1127 NM with high CFP and survival. 
    • Sabotage: 3551 TPI, 1076 NM with high production and solid type. 
  • Rise Up Real (NL)
    • +58 NVI to 468, with a strong longevity profile and good CFP. 
  • Torchlight (CH)
    • 1519 ISET with big, balanced production and health — a bull that fits the new ISET formula well. 

Formula losers — bulls that didn’t suddenly get “bad,” but whose index jobs changed:

  • Garza (USA)
    • –125 TPI under the new 24P/14F slice, despite being a very strong fat bull. 
  • Rozline (CA)
    • –626 Pro$ and –137 LPI, shifting him from income anchor to high‑type, strong‑component specialist. 
  • Beautyman (CH)
    • –159 ISET and out of the top 20, making him a more niche choice for specific traits than a front‑end ISET sire. 

Quiet anchors — bulls that got trimmed but still do exactly what you hired them to do:

  • Pattern and Cabo (CA)
    • Both lose about 200–250 Pro$ but stay #1 and #2 Pro$, with strong CFP and workable type. 
  • Rainow and Fugleman (Nordic)
    • Rainow slides 42 → 40 NTM, Fugleman climbs 35 → 38 NTM with better yield, udder health, claws, and milkability 126 — a classic pair of high‑reliability anchors for robot herds. 
  • Captain (NL proven)
    • +74 NVI to 363, now proven #2 NVI, confirming his status as a long‑haul bull, not a flash. 

Once you look at them through those lenses, “What’s this bull’s job now?” becomes a better question than “What rank did he hit on one list?”

What This Means for Your Operation

Here’s where this turns into a 30‑day job, not just an interesting April reading.

1. In the next 30 days, pull your sire list and highlight any bull who moved more than about 80 index points this run.

  • In the US, that’s bulls like Powerhouse (+119 TPI) and Garza (–125 TPI). 
  • In Canada, it’s Rozline (–626 Pro$), Graziano (–444 Pro$), and even the –237/–231 Pro$ trims on Pattern and Cabo.
  • In Switzerland, bulls like Torchlight (+65 ISET) and Beautyman (–159 ISET) deserve a second look. 

If a bull shifted more than ~80 points on the main index you’re using (TPI, Pro$, NVI, gPFT, NTM, etc.), you should consciously re‑decide whether he’s an anchor, a specialist, or a bull you park for now.

2. Cap any single bull at roughly 15–20% of your matings and any single sire line at roughly 30–35%.

  • Look at how many matings trace back to Captain, Parfect/Renegade, Gameday/Hadley/Troy, Gladius/Vivify, CRV Delta, VH, RealSyn/Rome when you follow pedigrees one or two generations back. 
  • If any one of those clusters is more than about a third of your planned matings in the next year, deliberately add two or three strong outcross bulls — for example, Swiss sires like Caruthers‑S or Race, Red and polled options like Drouner KL Augustus P Red and Koepon OH Robin Red, or non‑VH genomic NTM bulls such as DG Brujito or AltaMULLER, depending on your market. 

You’re not trying to avoid every trace of Captain or Parfect. You’re just making sure you still have options in three years when your best heifers are ready to flush.

3. Match your main index to how you actually get paid and where you’re bleeding money.

  • If you’re quota‑limited or selling into cheese and component‑heavy markets, give more weight to Pro$, NM$, INET, and gPFT than to pure TPI/PLI height. 
  • If your biggest headaches are cull cows, feet, and fertility, you may be better off stacking NVI, NTM, ISET, or health‑tilted bulls within TPI/PLI, even if they don’t carry the very highest overall index number. 

The bull that fits your milk cheque best may not be the one that looks prettiest on a global list.

4. Treat “formula winners” and “formula losers” differently — without either panicking or ignoring them.

  • Bulls like Powerhouse, Woodford, Rise Up Real, Torchlight, and Parfect are now better aligned with their main index; if they already fit your herd’s needs, they probably deserve more semen share. 
  • Bulls like Garza, Rozline, Beautyman become specialists: fat bulls, type bulls, or outcross tools used on cows where those specific strengths really matter, not on every fresh heifer. 

You don’t have to throw your favorite bull out of the tank. You have to stop pretending the index says the same thing it did last December.

5. Make proof‑run review a habit instead of an emergency.

  • Build a simple April habit: every time the proof run lands, spend an evening doing exactly what that Wisconsin herd did — mark big movers, check sire lines, and re‑tier bulls into anchors, specialists, and parked. 
  • Keep a short, hand‑written or digital note for your key sires: “movement this run” + “role now”. Over two or three runs, you’ll see which bulls hold steady and which ones re‑rank every time.

If you only do one thing from this article, do that 30‑day audit before you breed another cow as if nothing changed.

Key Takeaways

  • If a bull moved more than about 80 points on his main index this run, don’t assume he’s still doing the same job in your program. Big upward movers may deserve more matings; big downward movers probably belong in narrower, trait‑specific lanes instead of carrying your whole herd. 
  • If anyone’s family accounts for more than roughly a third of your planned matings, you’re not diversified — you’re boxed in. With Captain, Parfect/Renegade, Gameday/Hadley/Troy, Gladius/Vivify, CRV Delta, VH, and RealSyn/Rome showing up on lists from Wisconsin to Switzerland, capping them is the only way to keep mating options open in three years. 
  • Genomic #1 is a marketing label; the real breeding decisions live in the band behind it. With tight top‑10 spreads and high turnover, you’re better off picking three or four bulls with the right shape than paying extra for one name at the very top. 
  • Matching your index to your actual payment and bottlenecks is worth more than chasing a global rank. If components, robots, feet, or fertility are what really make or break your cheque, choose bulls and systems that pay on those traits, even if they aren’t “#1” anywhere. 

The Bottom Line

At the end of a long day in the barn, the proofs are still just paper. The daughters in your pens are the real scorecard. So next time you open the semen fridge, which of those bulls are you still using like it’s December — and which ones are finally ready to move up or down a tier in your own program?

Rise Up Real Surges +58 Past Moti to NVI #1 | April 2026 Netherlands: Where Even +30 Gains Lost Ground

Wednesday, April 8th, 2026

Rise Up Real sits at NVI #1 with an INET of 614 — barely top-10 for production. His Lvd of 1084 carried him past bulls earning €200+ more per lactation. NVI is telling you what it values.

Executive Summary: Rise Up Real vaulted +58 NVI to dethrone Genosource Moti and claim the Netherlands’ #1 genomic spot at +468, April 2026 — but his INET of 614 wouldn’t crack the top 5 on production alone. Every returning bull in the B&W genomic top 10 gained points, yet Halifax Delta Dawn still dropped three spots with a +19 gain because the floor rose +38 in a single run. On the proven side, Genosource Captain jumped +74 NVI on daughter data to land at #2, while December’s #1 Badger Ssi Ahead held position with just a +6 gain. The R&W genomic list is a different animal: 60% churn, six new CRV Delta bulls, and if you’re running a red program without monitoring that prefix concentration, you’re stacking pedigrees fast. CRV now holds 5 of 10 B&W genomic and 6 of 10 R&W genomic slots — pull your mating list and audit sire-line overlap before your next semen order. If you’re still running December-level allocations on Peak Fugleman MW (proven #10 → #56) or Peak Altazingler (#7 → #21), that’s money pointed at yesterday’s rankings.

April 2026 Dutch NVI

The April 2026 Dutch NVI genomic run has a new leader. Rise Up Real (Tot) surges from #3 to #1 at +468 NVI, April 2026—up +58 points from his +410 NVI, December 2025—the joint-largest gain among any returning top-10 sire. Bento (GGI), a Bench × Gigaliner son, matched that +58-point leap to vault from #7 to #2 at +450 NVI, April 2026, pushing December’s #1, Genosource Moti (CRV), down to #3 despite Moti himself gaining +27 points.

On the proven side, Genosource Captain (STG) delivers this cycle’s most dramatic daughter-confirmed reranking: +74 NVI, from #9 to #2, at +363 NVI, April 2026. Meanwhile, the Red & White genomic list has been effectively rewritten—six of ten slots are new entrants, all carrying the CRV Delta prefix, led by Delta Bloss-Red at +454 NVI, April 2026. The questions this raises about concentration are worth a hard look.

  • Remarkably stable top group: 9 of 10 return from December’s top 10; Chanello is the sole new entrant, replacing the sole dropout, Delta Time Jump P (Dec #5, +397 NVI, December 2025 → +403 NVI, April 2026—gained +6 but slid out as the pack surged past). 
  • Index band shift: The #1 value jumped from +420 to +468 (+48 at the ceiling); the floor rose from +386 to +424 (+38). The entire top 10 lifted substantially.
  • Universal inflation: Every returning sire gained NVI. The smallest gain among returnees was +19 (Halifax Delta Dawn); the largest was +58 (Rise Up Real and Bento). A bull that gained fewer than +30 points lost ground in relative rank.
  • Re-ordering within a stable group: The real story isn’t churn—it’s reshuffling. Rise Up Real climbed 2 spots, Bento climbed 5, and Genosource Mystro climbed 3. Halifax Delta Dawn dropped 3 spots despite gaining +19 NVI, and Delta Standout RF fell from #6 to #10 with a +30 gain—illustrating how even substantial NVI growth doesn’t hold rank in a rising-tide run.

Big Risers

Rise Up Real (Tot) and Bento (GGI) share the largest gain at +58 NVI each. Rise Up Real, a polled Real Syn × Freewood cross, jumped from #3 to #1 (+410→+468, April 2026). His INET of 614 is below the top-10 median (719), meaning his NVI gain is driven more by functional traits—his Lvd of 1084 is well above average. Bento climbed from #7 to #2 (+392→+450, April 2026) with a more balanced profile: INET 673 and Lvd 1109 both land solidly mid-pack.

Genosource Mystro (CRV) jumped three spots from #9 to #6 with a +45 NVI gain (+386→+431, April 2026). His INET of 881 is by far the highest in the top 10, making him the production standout—but his Lvd of 751 is the lowest, a classic yield-vs-longevity trade-off.

Genosource Benson (CRV) added +43 NVI (+386→+429, April 2026), moving from #10 to #8. A Radical son with the top-10’s highest Lvd at 1251—an extraordinary longevity prediction that, at 70% reliability, still carries re-ranking risk.

Relative Losers: Gaining Points, Losing Ground

In a run where even +30 NVI wasn’t enough to hold position, three December top-10 members gained points but fell in rank.

Genosource Moti (CRV) fell from #1 to #3 despite gaining +27 NVI (+420→+447, April 2026). In a run where the median returnee gained +39, Moti’s below-median improvement cost him two spots. His INET of 743 and Rel of 69% remain solid, but his Lvd of 881 is mid-pack.

Halifax Delta Dawn (Adv) dropped from #2 to #5 with the smallest gain among returnees: +19 NVI (+414→+433, April 2026). His INET of 801 is the second-highest in the top 10, but that production strength didn’t translate into enough NVI uplift to maintain his December position. For herds weighing revenue per lactation, Halifax’s relative slide in NVI matters less than its INET rank.

Delta Standout RF (CRV) fell from #6 to #10 despite gaining +30 NVI (+394→+424, April 2026). His Lvd of 723 is the lowest in the top 10, and his INET of 661 is mid-pack—a profile that didn’t benefit as much from this run’s inflation.

Delta Time Jump P (CRV) is the sole December top-10 dropout, sliding from #5 (+397 NVI, December 2025) to approximately #13 (+403 NVI, April 2026)—gaining just +6 points, the weakest gain among any former top-10 bull.

How Is NVI Rewarding the Current Top 10?

The NVI formula applies a 0.32 multiplier to INET (production euros) but weights UGH (udder health) at 5.5 and VRU (fertility) at 6.5 on their standardized scales, meaning a 1-point gain in health or fertility moves NVI more than an equivalent percentile gain in production alone. This run’s top 10 reflects that weighting:

  • Longevity dominates the risers. Rise Up Real (Lvd 1084), Bento (Lvd 1109), Genosource Benson (Lvd 1251), and Chanello (Lvd 1106) all carry Lvd above 1000. Six of ten sires exceed Lvd 1000.
  • Production pays differently. Halifax Delta Dawn brings the second-highest INET at 801, and Genosource Mystro leads with an INET of 881—but both sit in the bottom half for Lvd. Halifax trades longevity (Lvd 825) for component yield; Mystro trades it more aggressively (Lvd 751). 
  • The NVI-INET disconnect is real. Rise Up Real is NVI #1, but his INET of 614 ranks him near the bottom of the top 10. Halifax is NVI #5 but would rank near the top on INET alone. For herds prioritizing revenue per lactation over lifetime performance, the NVI ranking order doesn’t match the production ranking order.

Stud and Sire-Line Concentration

  • CRV holds 5 of 10 spots (Genosource Moti, Delta Miller, Genosource Mystro, Genosource Benson, Delta Standout RF)—unchanged from December, when CRV also held 5 of 10 (Moti, Delta Miller, Delta Time Jump, Delta Standout RF, and Mystro/Benson tied at #9–10). Three carry Genosource branding; two carry the Delta prefix. 
  • GGI holds 2 spots (Bento and Fis Fly P) on different sire lines (Bench and Kings-Ransom), providing internal diversity within the stud’s top-10 presence. 
  • Outcross options in the top 10: Rise Up Real (Tot, Real Syn × Freewood) and Chanello (independent, Real Syn) both trace to the Real Syn sire line but through different dams and studs. Halifax Delta Dawn (Adv) breaks the CRV/GGI pedigree pattern entirely for herds needing kinship relief. 

How Stable Is This Genomic Top 10?

  • All 10 sires are genomic with reliabilities of 69–70%. No daughter-proven bulls appear. Every number in this table is a prediction, not a confirmed result. [INTERNAL LINK: Understanding Genomic Reliability — Why Top-10 Lists Change Every Run] 
  • This is an unusually stable run. Only 1 of 10 is a new entrant (Chanello), and 9 of 10 held top-10 status across both runs. That 10% churn rate is remarkably low for a genomic list at 69–70% reliability—a contrast with the R&W genomic list’s 60% churn this same run.
  • Relative anchors: Rise Up Real and Genosource Moti have now held top-3 positions across two consecutive runs. Bento climbed from #7 to #2 over the same span. Delta Miller held #4 in both runs. These four offer the most consistent genomic reliability, though even two runs do not constitute proof. 
  • Re-ranking within the group matters more than dropout risk this run. Halifax Delta Dawn’s 3-spot drop despite gaining +19 NVI, and Delta Standout RF’s 4-spot drop despite gaining +30, show that relative positioning can shift substantially even when the roster is stable.

  • Genosource Captain (STG, 83% Rel) is this run’s proven breakout: +74 NVI gain, from +289 (Dec 2025, #9) to +363 (Apr 2026, #2). Daughter data massively upgraded his production credentials (INET 725), though his Lvd of 626 is a watch point. [EDITOR NOTE: Captain’s +74 NVI proven gain is a natural spin-off candidate for a sire spotlight feature.] 
  • Sunrise Superfly Rio (Tot, 77% Rel) gained +52 NVI, from +304 (#6) to +356 (#3). A balanced profile: INET 702 and Lvd 867 are both in the top third of this table. 
  • Alta/Peak dominance: 4 of 10 carry the Alta/Peak prefix. In December, Altazemini ranked #2; now it ranks #6 (–16 NVI). Altazingler has fallen from #7 to #21 (–32 NVI). Peak Fugleman MW suffered the worst proven drop: from #10 to #56, losing –44 NVI.

Only Badger Ssi Ahead, December’s #1, held firm.

  • December’s #1 slides: Ell Schach Skat (GGI) was R&W #1, with +382 NVI. He gained +18 to +400 in April 2026, but dropped to #7 as the CRV wave pushed past. December’s #2, Brakels Elevate Rammstein (Kam), fell to #12 (+373 NVI, April 2026). 
  • CRV concentration is extreme: 6 of 10 are CRV bulls, all Delta prefix. For R&W programs, sourcing outside CRV means choosing from a very short list. 
  • Delta Pronto P-Red gained the most among returnees: +54 NVI (+351→+405, April 2026). Delta Flagship P-Red gained +39 NVI but carries a conspicuously low INET of 237—the lowest in the R&W top 10 by a wide margin. His NVI rank is built almost entirely on functional traits. 
  • The R&W-B&W gap is closing. The R&W #1 at +454 NVI approaches the B&W genomic top 3. Delta Richman’s INET of 740 is competitive with B&W genomic leaders. 

Where the Indexes Agree — and Where They Don’t

The genomic, proven, and R&W lists rank different populations, so direct cross-list comparison isn’t possible. But within each list, the tension between NVI ranking and sub-index profiles reveals where breeding philosophies diverge.

Consensus Pattern

Across all three lists, bulls combining moderate-to-strong INET with above-average Lvd dominate the NVI top 3. Rise Up Real (INET 614, Lvd 1084), Bento (INET 673, Lvd 1109), and Sunrise Superfly Rio (INET 702, Lvd 867) all achieve NVI leadership without extreme production or extreme longevity—they sit in the upper-middle range of both.

Rank-Divergent Sires

BullNVI RankINETLvdDivergence Signal
Genosource Mystro (B&W Gen)6881751Highest INET in B&W Gen top 10, lowest Lvd band. Pure production play.
Halifax Delta Dawn (B&W Gen)5801825Second-highest INET, below-median Lvd. Revenue-per-lactation sire.

Peak Breaking News (B&W Prov)5310854Lowest INET in proven top 10 by a wide margin. NVI rank entirely from functional traits.
Delta Flagship P-Red (R&W Gen)9237754Lowest INET in R&W top 10 (by 203 pts). Health-fertility specialist.

The Core Tension This Run

NVI’s functional-trait weighting continues to reward bulls whose production credentials alone wouldn’t crack the top 20 on INET. Peak Breaking News at proven NVI #5 with an INET of just 310, and Delta Flagship P-Red at R&W NVI #9 with an INET of 237, are the starkest examples. Meanwhile, Genosource Mystro’s INET of 881 earns him only NVI #6 because his Lvd of 751 drags his total-merit score. The practical question for breeders: if your herd’s economics are driven primarily by milk revenue per lactation, NVI’s top 10 overweights longevity and health relative to your cashflow reality. If your economics depend on cow survival and replacement costs, NVI’s weighting aligns well with your situation.

How to Use These Sires This Season

Cross-Index Leaders

For herds wanting a single-sire shortlist that balances production, health, and longevity without extreme trade-offs: Rise Up Real (+468 NVI, INET 614, Lvd 1084, April 2026) and Bento (+450 NVI, INET 673, Lvd 1109, April 2026) occupy this space. Both held top-10 status across two consecutive runs—Rise Up Real at #3→#1, Bento at #7→#2. For herds prioritizing overall genetic gain with moderate risk tolerance, these are the lead candidates.

High-Reliability Anchors

If daughter-proven confidence matters more than genomic ceiling: Badger Ssi Ahead (+364 NVI, 81% Rel, April 2026) and Genosource Captain (+363 NVI, 83% Rel, April 2026) are the proven leaders. Genosource Captain’s +74-point gain suggests his genomic prediction was conservative—his daughters are outperforming expectations. If your conception rate or semen budget demands fewer, higher-confidence matings, these two reduce re-ranking risk substantially.

Production-First Sires

High-input herds chasing revenue per lactation should consider Genosource Mystro (INET 881, NVI #6, April 2026) and Halifax Delta Dawn (INET 801, NVI #5, April 2026), which have the strongest production profiles in the genomic top 10. The trade-off is explicit—Mystro’s Lvd of 751 and Halifax’s Lvd of 825 are both below the top-10 median of 1031. If your herd manages longevity through management rather than genetics, these bulls deliver more revenue per daughter per lactation.

Longevity and Functional-Trait Specialists

Grazing, robotic, or low-input systems where cow survival and health costs dominate the P&L should consider Genosource Benson (Lvd 1251, NVI #8, April 2026), who carries an extraordinary longevity prediction. Chanello(Lvd 1106, NVI #9, April 2026) offers a non-CRV alternative with similar Lvd strength. Be cautious—Benson’s Lvd is the highest in the entire top 10 by 142 points, which at 70% reliability could compress significantly on re-evaluation.

R&W Outcross Options

R&W breeders facing CRV saturation (6 of 10 R&W genomic sires are CRV Delta) have limited non-CRV options: Ell Schach Skat (GGI, +400 NVI, Lvd 1092, April 2026), Cardiff P-Red (GGI, +378 NVI, Lvd 1240, April 2026), Poppe Freelance Cr (Kam, +405 NVI, April 2026), and Hlb Crawford Cr (Indep, +392 NVI, April 2026) are the only non-CRV options in the R&W top 10.

30-Day Action

Pull your current mating list and audit sire-line overlap. If more than 30% of planned matings trace to CRV Genosource or CRV Delta bulls, you have a concentration risk that this run’s data makes visible. Cross-check whether Delta Time Jump P—the sole B&W Genomic top-10 dropout (Dec #5, now ~#13 at +403 NVI, April 2026)—is still in active rotation and re-evaluate its allocation. On the proven side, review whether Peak Fugleman MW (Dec proven #10, now #56 at +243 NVI, April 2026) or Peak Altazingler (Dec proven #7, now #21 at +271 NVI, April 2026) are still allocated at December-level semen volumes.

Key Takeaways:

  • The entire B&W genomic top 10 inflated — but not equally. Rise Up Real and Bento each gained +58 NVI to claim #1 and #2; Halifax Delta Dawn gained +19 and dropped three spots. In this run, anything below +30 meant losing ground even if your bull’s numbers went up.
  • NVI is rewarding longevity over production, hard. Rise Up Real leads at +468 NVI with an INET of just 614 — carried by Lvd 1084. Genosource Mystro’s INET of 881, the highest in the top 10, only buys him #6. If your herd economics are lactation-revenue-driven, NVI’s ranking order doesn’t match your cashflow reality.
  • Genosource Captain is the proven story of the run. A +74 NVI jump on daughter data — from #9 to #2 at 83% reliability. His cows outperformed his genomic prediction by a wide margin. At that reliability, this isn’t noise.
  • CRV concentration demands a mating-list audit. Five of ten B&W genomic slots, six of ten R&W genomic slots — all Delta prefix in the reds. If more than 30% of your planned matings trace back to CRV lines, this run just made that risk visible. Pull the list before your next order.
  • December’s proven picks are bleeding out. Peak Fugleman MW dropped from #10 to #56 (–44 NVI). Peak Altazingler fell from #7 to #21 (–32 NVI). If either bull is still in your tank at December allocation levels, you’re paying for rankings that no longer exist.

Connect 167, 7 Sires at 161: Why Germany’s Tightest RZG Run Is Really About Bloodline Risk

Wednesday, April 8th, 2026

Picard’s 148 proven RZG won’t win a headline contest — but it won’t re‑rank on you next December either.

Executive Summary: Germany’s April 2026 RZG top 10 didn’t reshuffle — it compressed. Connect holds at 167, but seven sires now sit at exactly 161, squeezing the #1-to-#10 band from 7 points to just 6. Every bull in that top 10 is a returner from December, and every one is still genomic-only — no daughter-proven sire cracks this tier. Picard leads the proven list at 148 RZG (+1 from December), offering run-to-run stability that the genomic cluster can’t yet deliver. The concentration problem is harder to ignore: RealSyn and Rome bloodlines account for at least half the top 10, and if your sire stack mirrors that, you’re building inbreeding pressure into your next generation. Pull your active bull list this month, cap your RealSyn/Rome exposure, and make sure Picard, MustHave, or a Red-carrier like SaturnRDC is in the rotation. When the index can’t separate seven bulls, the bloodline strategy becomes the tiebreaker.

Connect holds the line. Germany’s April 2026 RZG evaluation lands with the Comet son exactly where he stood in December — 167 RZG on both the Interbull and domestic genomic lists, unmoved run to run. All 10 Interbull genomic top‑10 sires return from December 2025 with no new entrants, so this is a stability run at the very top of German Holstein Black & White.

That stability is deceptive, though. The gap between Connect and the pack shrank: the #1‑to‑#10 band compressed from 7 points (167–160 RZG, December 2025) to just 6 (167–161 RZG, April 2026), with Remco climbing to 162 RZG from 161 and seven other sires all ticking from 160 to 161 over the same period. Meanwhile, the daughter‑proven world tells a different story — Picard edges up to 148 RZG in April 2026 from 147 in December, pulling Pattern, Zivet, Glarus, and Glenn into a tighter functional band that sits 13–19 points below the genomic elite but with far more reliability behind it. And in Red & White, HarmonicP arrives at 163 RZG in April 2026 (up from 161 in December 2025), suddenly competitive with half the B&W genomic top 10 and setting up the sharpest black‑vs‑red contrast this system has produced in recent runs.

  • Connect stays #1 at 167 RZG in April 2026, after 167 RZG in December 2025, while the rest of the top 10 compresses tightly at 161–163 RZG. 
  • All 10 are returning genomic sires; there are no new‑in‑top‑10 entrants in April 2026, and no December top‑10 drop‑outs. 
  • The band from #1 to #10 is now just 6 RZG points (167 to 161) in April 2026 versus 7 points last run (167 to 160), indicating further tightening at the top. 
  • Within the 161‑RZG pack, the +1 shifts from 160 RZG, December 2025, to 161 RZG, April 2026, signal micro‑re‑ranking rather than structural change. 

Big RZG risers inside the top 10

  • Remco climbs from 161 RZG, December 2025, to 162 RZG, April 2026, picking up on already strong RZ Milch and RZ Fleisch and pairing that with a balanced RZ Gesund block — a neat “more of everything” move without obvious new holes; as a fully genomic sire, his reliability remains materially lower than the proven anchors. 
  • Realpower steps from 160 RZG, December 2025, to 161 RZG, April 2026, with the profile leaning slightly more to RZ Milch and RZ Fruchtbarkeit than his RealSyn contemporaries, making him a marginally safer production‑plus‑fertility play in this cluster for herds wanting that tilt. 
  • Realside follows the same 160 to 161 RZG, December 2025 to April 2026 uptick, but does it with a touch more RZ Exterieur at the expense of RZ Persistenz, suiting type‑conscious herds that can live with slightly less longevity. 
  • TooHot also jumps from 160 to 161 RZG, December 2025 to April 2026, nudging up in RZ Gesundheit and RZ Kälberfit while accepting more modest RZ Exterieur, making him a health‑leaning option in the 161 group for herds prioritizing health over maximum type. 

Big fallers / notable drop‑outs

  • There are no big fallers within this specific Interbull genomic top 10: all nine 161‑RZG sires move just +1, and Connect and Veterano remain static between December 2025 and April 2026. 
  • Outside the top 10, MustHave holds 159 RZG, April 2026, after 159 RZG, December 2025, and therefore remains just outside the Interbull top 10; he retains clear strength in RZ Milch and RZ Fleisch, so still fits high‑component, index‑driven matings even if the headline rank hasn’t improved. 
  • On the domestic genomic list, Topchamp sits at 158 RZG in April 2026, unchanged from 158 RZG in December 2025, with a fractionally weaker RZFit profile than the very top group but a clearly strong RZ Exterieur, retaining niche value in type‑oriented programs despite staying out of the Interbull top tier. 

What this index is rewarding now

  • The current top 10 is clearly rewarding high RZ Milch combined with robust RZ Gesundheit and calf fitness: Connect sits at 120 RZ Milch, 113 RZ Gesundheit, and 135 RZGes, April 2026, while Remco (138 RZ Milch, 123 RZGes) and Realpower (117 RZ Milch, 118 RZGes) illustrate the “production + health” template. 
  • Trade-off-wise, Realside and Carlito bring more RZ Exterieur and RZ Fundament at the cost of slightly lower RZ Persistenz and RZ Kalbeverlauf compared with Connect and Realpower, so they upgrade frames and feet‑and‑legs but are a shade more management‑sensitive regarding longevity and calving ease. 
  • SaturnRDC shows how the system still pays for RZG in Red‑carrier packages when they can match B&W on RZ Milch and RZ Gesundheit, offering a color-flexible route into the same index logic for herds wanting that genetic option. 

Stud and family concentration

  • Synetics dominates the Interbull genomic top 10 with Connect, Realpower, Realside, and Grafti (just outside at 155 RZG, April 2026), while Phönix owns Remco, TooHot, Carlito, Romantiker, and much of the domestic 99‑RZG band. 
  • The RealSyn and Rome sire lines appear repeatedly (Realpower, Realside, RealSteel, RealLife, Roadhouse; Romantiker, Roadstar, Ramirez), making sire‑stacking around these brands a real inbreeding and diversity concern for anyone using multiple bulls from this cluster. 
  • As outcross moves within this context, MustHave (AltaMuller × non‑RealSyn dam stack) and Attention(Adonis × Arizona) are two practical options to step out of the RealSyn/Rome saturation while remaining at or above 158 RZG in April 2026. 

How stable is Germany’s RZG top tier right now?

  • All 10 Interbull genomic top‑10 bulls from December 2025 return in April 2026, with Connect and Veterano unchanged and the rest gaining just +1, so this is a low‑churn, low‑shock run at the elite end. 
  • The compression from a 7‑point band (167–160 RZG, December 2025) to 6 points (167–161 RZG, April 2026) means breeders are deciding between very similar total‑merit levels and need to lean more on trait shape, reliability, and pedigree than on raw RZG gaps. 
  • Because all of these sires are still genomic, the apparent stability shouldn’t be over‑interpreted as permanent; future daughter data could still significantly reshuffle this pack. 

Volatility and reliability

  • All top‑10 Interbull B&W RZG bulls are genomic; there are zero daughter‑proven sires in this list, so the top is structurally volatile and still heavily genomic‑weighted in terms of reliability. 
  • Connect at 167 RZG, April 2026, and Remco at 162 RZG, April 2026, are the key high‑index/low‑reliability volatility plays; both sit on moderate daughter numbers and heavy genomic weight, so large swings remain possible as daughter information accumulates. 
  • On the proven side, Picard at 148 RZG, April 2026 (147 RZG, December 2025) and Pattern at 145 RZG, April 2026 (145 RZG, December 2025) are the obvious anchors, with full daughter‑proven reliability and stable multi‑run RZG. 
  • Glenn and Glarus, both at 143 RZG in April 2026, with small negative or flat moves vs 143 RZG in December 2025, provide additional high‑reliability ballast for programs that want fewer surprises than the genomic cluster offers. 

Domestic RZG B&W Genomics — A Different Top 10

4Realside161 RZG, Apr 20265
5TooHot161 RZG, Apr 20266
  • Connect, Remco, and Realpower lead both the Interbull and domestic genomic lists, so domestic usage aligns more closely with the global RZG picture in April 2026 than in December 2025. 
  • Key movers here are the same as at Interbull: Remco, Realpower, Realside, and TooHot all add +1 RZG from December 2025 to April 2026, but their domestic rank order emphasizes local availability and stud alignment over raw value changes. 
  • The domestic list adds nuance: SaturnRDC at 161 RZG, April 2026, and Roadhouse at 160 RZG, April 2026 (both unchanged from their December 2025 RZG levels) bring Red‑carrier and slightly more RZ Fruchtbarkeit and RZ Kalbeverlauf into the same band, which the Interbull headline table partially hides. 
  • Overall, this index rewards roughly the same traits as Interbull RZG, but domestic ranks give extra weight to health and calving ease (SaturnRDC, SemianRDC) and to stud portfolio breadth.

  • Picard leads the proven list at 148 RZG in April 2026, after 147 RZG in December 2025, while the genomic Connect/Remco/Realpower group sits 13–19 points higher but without his high daughter‑proven reliability. 
  • Pattern stays solid at 145 RZG, April 2026 vs 145 RZG, December 2025, and Zivet edges up to 144 RZG, April 2026, from 143 RZG, December 2025, while keeping a very even mix of RZ Milch, RZ Exterieur, and RZ Gesundheit, making them calmer, all‑round options compared with the more aggressive genomic plays. 
  • Glarus and Glenn hold at 143 RZG, April 2026, both offering strong RZ Exterieur and RZEuterus structure, so they remain go‑to options for herds wanting uniform udders and legs without giving away too much total RZG. 
  • This index clearly rewards proven production plus functional traits over sheer RZG height: the top‑5 proven sires sit below the genomic elite but come with far tighter RZ and RZGes confidence bands. 

Where the Indexes Agree — and Where They Don’t

Consensus sires

  • Connect is #1 on both Interbull genomic and domestic genomic RZG at 167 RZG, April 2026, so any RZG‑focused genomic program that down‑weights him is consciously stepping away from the system’s own consensus. 
  • Remco sits #3 on Interbull genomic and #2 domestically at 162 RZG, April 2026, with almost identical trait shape in both systems, making him the logical high‑index “second pillar” behind Connect in RZG‑driven genomic stacks for herds comfortable with genomic risk. 
  • On the proven side, Picard at 148 RZG, April 2026 (147 RZG, December 2025), and Pattern at 145 RZG, April 2026 (145 RZG, December 2025), appear consistently at or near the top of daughter‑proven lists, reflecting the cross‑index agreement that these are the current reliability kings. 

Rank‑divergent sires (illustrative table)

  • Connect and Remco are true cross‑index leaders inside genomics, but they don’t appear on the proven tables yet; for breeders, that’s the classic “high reward, high volatility” trade: for herds prioritizing fast genetic gain and willing to tolerate future re‑ranking, they are obvious first‑line sires. 
  • Realpower looks slightly better domestically (rank 3) than his Interbull rank (4) suggests, reflecting how his trait mix — particularly RZ Fruchtbarkeit and RZFit — is valued by German buyers; for herds prioritizing fertility within a high‑RZG genomic stack, he’s the more conservative complement to Connect and Remco. 
  • SaturnRDC only appears as a domestic genomic 161‑RZG, April 2026 bull, and doesn’t touch the Interbull top 10, but his RZ Gesundheit and RZ Kalbeverlauf profile makes him valuable for herds with calving and heifer health issues, even though his headline rank lags the main B&W leaders. 
  • Picard sits outside all genomic lists but dominates proven RZG at 148 RZG in April 2026; for risk‑averse programs and commercial daughters‑first herds, his lower index but higher reliability is a rational choice, especially where re‑ranking risk has a real economic cost. 

Core tension

The core tension in this April 2026 German run is between a very tight cluster of 161–167 RZG Interbull genomics bulls — headed by Connect, Remco, and Realpower — and a slightly lower, but far more stable, proven layer anchored by Picard, Pattern, and Zivet. Genomic lists are converging rather than exploding: many bulls at 161 RZG, April 2026, with near‑identical trait profiles, making stud affiliation, pedigree, and management fit more decisive than raw index points. Proven lists, meanwhile, still edge up slowly in RZG (Picard +1, Zivet +1 between December 2025 and April 2026) but don’t threaten genomic heights, so breeders have to choose how much of their heifer and heifer‑dam matings they want to allocate to “167‑RZG genomic volatility” versus “145–148‑RZG proven stability.” Red & White adds a further layer: HarmonicP at 163 RZG, April 2026, and SkypeRed at 163 RZG, April 2026 are genuinely competitive with black‑and‑white indexes, but proven red sires still sit lower, amplifying the same risk‑reliability tension in another color.

How to Use These Sires This Season

  • Cross‑index genomic leaders (Connect, Remco, Realpower)
    For herds prioritizing maximum RZG gain and comfortable with genomic volatility, use Connect as the main sire of sons and heifers, backed by Remco and Realpower on cows, but cap any single bull at a modest share of matings to manage re‑ranking risk. For high‑input housed and robot herds that can fully exploit high RZ Milch and RZGes, this trio fits, while lower‑input or grazing‑leaning systems may want to temper their use with more moderate‑production sires. 
  • High‑reliability anchors (Picard, Pattern, Zivet)
    For herds prioritizing predictability, udder consistency, and moderate calving risk over absolute index height, use Picard and Pattern on high‑value older cows and on problem‑free family lines where you want uniform, saleable daughters, then bring Zivet in to keep RZ Milch and RZGes balanced. 
  • Health and fertility specialists (TooHot, SaturnRDC, Roadhouse)
    For herds targeting better fertility, calf survival, and trouble‑free calvings, deploy TooHot and SaturnRDC on heifers and health‑challenged cow families, while Roadhouse can be used where you want to hold RZG around 160, April 2026, but nudge RZ Fruchtbarkeit and RZ Kälberfit upward, giving up a few points vs Connect and Remco in exchange for more health insurance. 
  • Type‑leaning sires (Realside, Carlito, Glarus, Glenn)
    For herds or show‑leaning segments prioritizing frames, udders, and legs, use Realside and Carlito in the genomic space, then Glarus and Glenn as proven follow‑up sires to lock in type once the pedigree and health package are acceptable. 
  • Outcross / de‑stacking sires (MustHave, Attention, MustHave‑line sons)
    For herds worried about RealSyn/Rome saturation, rotate MustHave and Attention into matings on Connect/Realpower/Remco daughters, accepting a small RZG discount relative to the very top in exchange for more flexible future mating options. 

Within 30 days, pull your current active sire list, mark all RealSyn, Rome, and Comet‑line bulls, and cap that group at a predefined percentage of matings while deliberately adding Picard, Pattern, MustHave, and at least one Red‑carrier like SaturnRDC or HarmonicP to diversify both pedigree and system risk.

Key Takeaways:

  • The top 10 is frozen but squeezed. All 10 Interbull genomic sires return from December, with Connect flat at 167 RZG, and the #1‑to‑#10 band narrowing from 7 points to 6 — raw index rank is no longer enough to pick between them.
  • RealSyn and Rome saturation are portfolio risks, not talking points. Those two sire lines account for roughly half the genomic top 10; herds using multiple bulls from this cluster are stacking the same pedigree and need MustHave, Attention, or a Red‑carrier like SaturnRDC to break the pattern.
  • Picard and Pattern are the only sires in this article that won’t surprise you next run. At 148 and 145 RZG (April 2026), they sit well below the genomic ceiling — but their daughter‑proven reliability means breeders aren’t betting on a number that could move 5+ points in either direction by December.
  • Health and fertility now separate the 161 pack. TooHot and SaturnRDC lean into RZ Gesundheit and RZ Kälberfit; Realside and Carlito lean into RZ Exterieur and RZ Fundament — same RZG, very different daughters, and the right pick depends on whether your problem cows need better immune function or better feet.
  • Your 30‑day move: audit your bloodline exposure. Mark every RealSyn, Rome, and Comet‑line bull on your active sire list, cap that group at a set percentage of matings, and deliberately slot in at least one proven anchor and one outcross genomic sire before the next mating round.

April 2026 USA Holstein TPI: Woodford +3565, Powerhouse +119 – Who Won and Lost the Protein Flip?

Wednesday, April 8th, 2026

Powerhouse just picked up +119 TPI while Garza dumped −125 under the protein flip — if those two are in your tank, this run just changed your semen budget math.

Executive Summary: TPI 2026’s 24P:14F protein flip just moved real money: Powerhouse gains +119 TPI, Garza drops −125, and every high‑fat sire in your tank needs a second look. All 10 genomic USA Holstein TPI leaders in April 2026 are new names and squeezed into a 37‑point band, so chasing “#1” is now a high‑volatility hobby, not a plan. On the proven side, Sheepster still leads at +3480 TPI after losing 92 points, while Captain, Zuri, and Garza reshuffle as the formula rewards protein‑heavy profiles. Woodford (+3565 TPI, +1296 NM$) and Jitters/Sabotage‑type genomics line up TPI and NM$ so closely that your “index vs profit” debate is basically over for top heifers. R&W breeders get their own shake‑up: Okafor‑Red and Ocean‑Red hold near 3200 GTPI, while RC/RW PTAT bulls like Crypto PP at +2.82 PTAT force you to choose between show udders and milk cheque. The article walks through how to re‑tier matings by herd type (high‑input, grazing, type/show, R&W), how to spot Captain/Trooper/Alta line stacking, and which bulls to push or park for the next 30 days.

The hook for April 2026 is the TPI 2026 formula flip: more weight on protein, less on fat, which quietly reshuffled both genomic and daughter-proven lists and set up the kind of bulls that now rise to the top in the Holstein USA TPI, April 2026 run. The biggest structural change is that PTA Protein now carries 24% of TPI while PTA Fat drops to 14%, so a bull with the same total CFP but more of it in protein pounds now scores materially higher TPI than a more fat‑heavy counterpart. When you run the December 2025 Holstein USA TPI proofs through that new 24P:14F production slice, you immediately see “formula winners” and “formula losers” before a single new daughter is added.

In this April 2026 USA run, that protein‑first logic shows up very clearly: genomic bulls like Aurora Gs Woodford‑ETare almost purpose‑built for TPI 2026, and on the proven side, bulls such as Peak Powerhouse‑ET gain roughly +119 TPI going from +3329 TPI (Holstein USA TPI, December 2025) to +3448 TPI (Holstein USA TPI, April 2026). At the same time, fat‑leaning sires like SDG Cap Garza‑ET lose relative ground despite still being excellent cowside options.

What Changed at the Top?

Genomic TPI leaders – April 2026

On the genomic side, the top 10 Holstein USA TPI, April 2026 bulls are all new faces compared with the December 2025 genomic top 10, reflecting both the formula change and the usual churn of new young sires.

The band from Woodford at +3565 down to Gustavsson at +3528 is extremely tight – just 37 TPI points separate #1 from #10 – and all ten are new entrants versus the December 2025 genomic top 10. That tells you two things:

  • The shape of the ideal genomic sire under TPI 2026 is clear (high milk, strong protein, good health, functional type), but
  • The names at the very top are volatile and will rotate as more calves and proofs arrive.

Proven TPI leaders – December 2025 vs April 2026

On the daughter‑proven side, the story is different: it’s movement, not churn. The top proven bulls are the same characters, but they reshuffle based on the formula change and the addition of fresh daughters.

Sheepster loses 92 points but still leads the Holstein USA TPI, April 2026 proven list at +3480 TPI, while Powerhouse is the classic “formula winner,” jumping about +119 TPI between runs thanks to his milk and protein‑heavy profile. Captain, Zuri, and Garza all surrender some ground under the new production weights but remain within the elite band.

All these proven sires meet the Holstein USA “high‑ranking sire” reliability criteria (minimum 80 traditional or 85 genomic for production and 80 for type), and the leaders are sitting in the 95–99% range on production and type, so this is the high‑reliability layer.

What TPI 2026 Is Rewarding (and Penalizing)

Protein vs fat in the new formula

Holstein USA’s TPI 2026 formula allocates 24% weight to PTA Protein and 14% to PTA Fat, shifting 5 percentage points from fat to protein compared with the previous version. Because of how the sub‑indices are scaled, Bullvine’s analysis shows that one pound of PTA Protein now exerts about 71% more leverage inside TPI than one pound of PTA Fat, turning P‑strong bulls into index winners without any change in their actual proofs.

Running the December 2025 Holstein USA TPI values through the new matrix, Bullvine highlighted several clear patterns:

  • Bulls with high protein and balanced or strong P/F ratios gained TPI – example case studies include:
    • Peak Powerhouse‑ET (1HO16089) – big milk, strong protein, climbs from +3329 to +3448 TPI between December 2025 and April 2026. 
    • Cookiecutter Horseshoe‑ET (208HO00356) – identified by Bullvine as jumping about 10 proven ranks under the 2026 formula, even on the same December proof set. 
    • Multiple Captain‑line bulls like Captain himself and his sons. 
  • Bulls whose component strengths skewed more to fat than protein lost a step:
    • SDG Cap Garza‑ET (551HO04474) – very strong on fat; surrenders roughly 125 TPI under the new weighting (from +3464 to +3339). 
    • Some high‑fat Captain sons and Garza‑type profiles that were standout under the old 19F:19P balance.

Trait profiles at the top – genomics

Looking at the Holstein USA TPI, April 2026 genomic top 10, the shared trait profile is obvious:

  • High PTA Milk – often +1200 to +1500 lb and beyond.
  • High PTA Fat and PTA Protein pounds, with a P/F balance that suits the 24P:14F weighting.
  • Strong health (PL, LIV, cow health/Health Index) and fertility, with SCS normally in a comfortable range.
  • Moderate positive type – enough PTAT and udder to build functional commercial cows, not extreme show type.

A few case studies:

  • Aurora Gs Woodford‑ET
    +3565 TPI (Holstein USA TPI, April 2026) and +1296 NM$ (Holstein USA NM$, April 2026), roughly +1498 PTA Milk, +142 PTA Fat, +120 PTA Protein, strong Health Index, and moderate but positive type.

    +3552 TPI (Holstein USA TPI, April 2026), +1127 NM$ (Holstein USA NM$, April 2026); big CFP with strong survival and fertility. 
  • Ocd Whoops Sabotage‑ET
    +3551 TPI (Holstein USA TPI, April 2026), +1076 NM$ (Holstein USA NM$, April 2026); high production and NM$ with solid type. 

Kingdom Formal, Baelum, Bridgerton, Pen‑Col Gs 86807, and Gustavsson all sit in this same high‑protein, high‑pounds, good‑health box with minor flavor differences in pedigree and trait tilt.

Trait profiles at the top – proven

On the proven side, the Holstein USA TPI, April 2026 leader board is full of “TPI 2026‑friendly” production profiles with proven reliability.

A snapshot of trait packages:

  • OCD Trooper Sheepster‑ET (7HO16276)
    +3480 TPI (Holstein USA TPI, April 2026); +133 Fat, +1359 Milk, 2.83 SCS, +4.9 PL, +0.6 LIV, +0.86 PTAT. 
  • Peak Powerhouse‑ET (1HO16089)
    +3448 TPI (Holstein USA TPI, April 2026); +113 Fat, +1937 Milk, 3.06 SCS, +2.7 PL, −0.1 LIV, +0.09 PTAT. 
  • Genosource Captain‑ET (551HO04119)
    +3356 TPI (Holstein USA TPI, April 2026); +117 Fat, +1789 Milk, 3.06 SCS, +3.6 PL, −0.6 LIV, +0.33 PTAT. 

Overall, the proven top 10 tends to run 150–250 TPI points below the genomic leaders, but with 95–99% reliabilities for production and type, making them much safer anchors.

AI Companies and Bloodlines: Who Owns the Top?

Across the Holstein USA TPI, April 2026 lists, there is a clear concentration by both AI company and sire line.

On the proven TPI top 10:

  • OCD appears prominently with Sheepster and several Trooper/Drive descendants in the extended top group.
  • Peak/Alta features strongly via Powerhouse and Momento, plus multiple AltaWheelhouse/AltaZazzle offspring.
  • Genosource delivers Captain and several Captain‑line sons (Garza, Capn Miguel, Capn Ramble) just inside or outside the top 10.
  • Denovo brings in Elgin under the Envy x Riveting cross.

Pedigree‑wise, a few sire lines are clearly over‑represented in the top 10 and just beyond:

  • Captain (and his sons) appear in multiple proven bulls’ pedigrees – Captain himself in the top 10, and Garza, Capn Miguel, Capn Ramble, Cap Diggory, etc., in the next band.
  • Trooper/Drive/Topdog influence shows through OCD sires like Sheepster, Shake, Draft, and Draft‑related bulls.
  • AltaZazzle/AltaWheelhouse/AltaMarius show up repeatedly in the background of Peak bulls.

For genomic users, this concentration means you cannot just buy “top‑10 genomic TPI” and assume diversity; a good proportion of those bulls will trace back to Captain‑line and AltaZazzle‑line sires. For proven users, it reinforces the need to spread semen across multiple companies and sire lines – e.g., pairing Captain‑line bulls with Envy/Riveting or Taos‑line bulls like Isaac – to manage inbreeding and diversify risk.

How Volatile Are These Rankings After the Protein Flip?

At the genomic level, volatility is a feature, not a bug.

  • All ten bulls in the Holstein USA genomic TPI top 10, April 2026, are new compared with the December 2025 genomic top 10. 
  • The TPI gap from #1 to #10 compressed to just 37 points (3565–3528), which means minor reliability or data shifts can shuffle ranks by several positions without any real change in bull quality. 
  • For genomic TPI users, this means rank volatility is high and shouldn’t be over‑interpreted; you want to treat the whole top band as a portfolio of similar bulls rather than betting on the “#1” name.

On the daughter‑proven side, the picture is much calmer.

  • The core of the top group is stable: Sheepster, Dominance, Captain, Momento, Zuri, and Garza were already high in December 2025, and remain in the top 10 in April 2026. 
  • Typical movement is ±20–40 TPI as more daughters arrive, with bigger shifts (Powerhouse +119, Garza −125) explained largely by the formula change rather than an abrupt change in daughter performance. 
  • With reliabilities at or near 99% for many of these bulls, the rank band is structurally stable; a few slots of shuffling don’t change their role as cow‑makers. 

For decision‑making:

  • Treat genomic ranks as high‑gain but high‑volatility signals: great for fast genetic progress, especially on heifers, but you should spread risk across several programs and not assume any one bull will stay #1.
  • Treat proven ranks as high‑reliability anchors: ideal for herds that want predictable daughters and for large semen volumes on milking cows and donors.

NM$: Economics Lined Up with TPI

The Holstein USA NM$, April 2026 genomic file confirms that TPI 2026 and NM$ are largely pointing to the same bulls.

10S-S-I Kingdom Formal-ET (7HO18241)+1139+3548#6 TPIAlignedHigh health index; balanced

For genomics, this means that choosing bulls on TPI alone is less risky than it used to be, because the top TPI list is now almost automatically high NM$ as well; NM$ is more of an economic cross‑check than a competing philosophy.

On the proven side, top TPI sires like Sheepster, Powerhouse, Captain, and Elgin also deliver competitive NM$, albeit a step lower than the very best genomics, which is exactly the reliability vs level trade‑off you expect.

PTAT and RC/R&W PTAT: Specialist Type Tools (with Top RC/RW PTAT Bulls)

The pure PTAT lists – black‑and‑white and Red/Red Carrier – are nearly a separate universe from the TPI/NM$ tables. From the Holstein USA PTAT, April 2026 file, top PTAT sires reach +3.5 to +4.0 PTAT, with huge udders and frames, but usually 150–200 TPI and several hundred NM$ below the Woodford/Jitters type of bull. In the Red Carrier/RW PTAT file, similar-type specialists exist for the Red Carrier and Red & White space.

If your herd prioritizes show and classification, these bulls are ideal when you have a top 5–10% type cow family and are willing to sacrifice some index and NM$ on a few matings to push udders and frames to the next level. If your herd prioritizes herd profitability, you should keep PTAT specialists under 5–10% of total matings and let TPI/NM$ leaders carry the main commercial load while PTAT bulls sculpt the show string and donor group.

Top RC/RW PTAT Bulls – April 2026 and How to Use Them

For herds that want show-ring udders and frames in the Red Carrier and Red & White space, the Holstein USA RC/RW PTAT, April 2026 list provides a small group of extreme‑type tools.

Highlighted RC/RW PTAT bulls – Holstein USA RC/RW PTAT, April 2026 (12‑month bulls)

Bull (NAAB)PTAT (Holstein USA RC/RW PTAT, April 2026)Notes
Ruann Karat‑45955‑ET (719HO45955)+3.92 PTATExtreme frames and udders; very low production and index.

Sunquest Holy Crypto PP‑ET (250HO18358)+2.82 PTATHomozygous polled with strong PTAT and respectable TPI.

These RC/RW PTAT bulls are not designed to compete with Woodford‑style sires on TPI or NM$; most carry negative production PTAs and lower indexes. If your herd prioritizes show or classification in Red or RC lines, you can use them strategically:

  • On the top 5–10% of Red and RC cows and heifers from your best type families, especially where udders and frames are already strong, and you want to push for the next level. 
  • For breeders who still need commercial performance in Reds, bulls like Sunquest Holy Crypto PP‑ET can be used on a slightly wider group, because he doesn’t step as far off the index cliff as some pure show sires. 
  • If your herd prioritizes profit and components, keep RC/RW PTAT-specialist usage under 5–10% of matings, and let Red index leaders (Okafor‑Red, Ocean‑Red, etc.) carry the main R&W commercial load. 

Red & White: Index and Type in the R&W Space

TPI 2026 doesn’t treat Red & White differently inside the formula, but the April 2026 USA Red & White GTPI tables show a similar protein‑forward pattern among top R&W bulls.

Top R&W TPI – Holstein USA GTPI, April 2026 (selected)

Bull (NAAB)TPI (Holstein USA GTPI, April 2026)NM$ (Holstein USA NM$, April 2026)PTA MilkPTA FatPTA ProPTATNotes
Denovo 21873 Okafor‑Red‑ET (29HO00951)3194+824+2270+73+31+1.24High‑index Red, strong CFP, good health.

Ocd Morris Spirit‑Red‑ET (551HO06757)3177+872+1536+81+11−0.06Big fat, good protein; strong fit for milk cheque.

Compared with December 2025, bulls like Okafor‑Red and Ocean‑Red hold their ground near the top while fat‑heavier R&W sires lose some relative shine; again, the protein‑leaning bulls are formula winners.

For type in the Red space, the Red Carrier/RW PTAT bulls above (e.g., Holy Crypto PP, Story Arc, Karat, Hulu Shoutout) provide show‑caliber udders and frames that you can layer on top of R&W index sires when you want Red daughters that still classify and show.

If your herd wants Red calves with a commercial index:

  • Look first at Okafor‑Red, Athens‑Red, Ocean‑Red, Spirit‑Red, and similar bulls at the top of the R&W GTPI and NM$ lists. 
  • Use RC/RW PTAT specialists sparingly on top Red females where type is high-priority.

What This Means for Your Matings This Season

This is where the April 2026 USA Holstein proof run earns its keep: turning lists into portfolio and mating moves over the next 30 days.

High‑input, housed herds chasing milk cheque and NM$

If your herd is high‑input, housed, and paid strongly on volume plus components, consider:

  • Heifers and genomic donors
    • Use Aurora Gs Woodford‑ET, Genosource Jitters‑ET, and Ocd Whoops Sabotage‑ET heavily on your top 25–40% heifers and genomic donors to maximize TPI (Holstein USA TPI, April 2026) and NM$ (Holstein USA NM$, April 2026). 
    • Layer in Beyond Mican Hagrid‑ET or S‑S‑I Richard Chichester‑ET where you need a different program or P/F bias to manage inbreeding.
  • Milking cows and ET recipients
    • Anchor matings with OCD Trooper Sheepster‑ET, Peak Powerhouse‑ET, and Genosource Captain‑ET to lock in high CFP, PL, and reliability on cows that are already working hard. 
    • Accept slightly lower TPI vs genomics in exchange for near‑99% reliability – especially on older cows and donor dams. 

Grazing / lower‑input or fertility‑sensitive herds

If your herd prioritizes fertility, survival, and robustness more than absolute production:

  • On heifers, lean more into genomic bulls like Chichester, Jitters, and Sabotage that balance components with very strong health and fertility, rather than chasing the last 50–80 pounds of milk. 
  • On cows, emphasize proven sires with strong PL/LIV and fertility – e.g., Sheepster, Dominance, Zuri, Sensei– and limit the number of high‑milk but tougher‑fertility bulls like some Captain sons on cows that already struggle to breed back. 

Type/show and classification‑focused herds

If your herd is type/show‑oriented, and you’re willing to give up some TPI/NM$:

  • Keep TPI/NM$ leaders (Woodford/Jitters/Sheepster) as the core for commercial matings, but
  • On the top 5–10% of your best type cows and heifers, layer in:
    • High PTAT black‑and‑white bulls from the Holstein USA PTAT, April 2026 file for udders and frames. 
    • RC/R&W PTAT bulls like Sunquest Holy Crypto PP‑ET, Ruann Karat‑45955‑ET, or Redcarpet Story Arc‑ET on elite Red or RC families to upgrade type while maintaining some index. 
  • You gain +3.0 to +4.0 PTAT udders and frames, but you typically give up 150–200 TPI and several hundred NM$, so keep these matings targeted. 

Red & White focused herds.

If your herd prioritizes Red & White genetics:

  • Build your main Red program on Okafor‑Red, Athens‑Red, Ocean‑Red, Spirit‑Red, and similar high‑GTPI/NM$ R&W bulls from the Holstein USA GTPI R&W, April 2026 list. 
  • Introduce RC/RW PTAT sires only on your top R&W cows and heifers, where show/classification is the priority.
  • Watch bloodline stacking – spreading semen across Denovo, STgen, OCD, and Aprilday R&W bulls helps keep Captain/Trooper/Alta lines from becoming too dense in your Red base. 

30‑day action list

Within the next 30 days, for any USA Holstein program using TPI and NM$:

  1. Audit your sire list against movement
    1. Pull your current sire lineup and, using the December 2025 and April 2026 Holstein USA TPI lists, flag any proven bull that lost ≥80 TPI (e.g., Garza) and any that gained ≥80 TPI (e.g., Powerhouse). 
    1. Decide whether those “formula losers” still fit your herd’s fat vs protein economics and whether “formula winners” deserve a higher semen share.
  2. Check bloodline concentration
    1. Using the pedigrees in the April 2026 proven and genomic lists, highlight how many of your active bulls trace back to Captain, Trooper/Drive/Topdog, or AltaZazzle/AltaWheelhouse as sire or grandsire. 
    1. If a single line dominates, deliberately add a couple of strong non‑Captain/non‑Trooper bulls (e.g., Envy x Riveting like Elgin, Taos‑line bulls like Isaac) to create outcross options.
  3. Re‑tier your matings by risk.
    1. Re‑assign at least 60–70% of milk‑cow matings to proven bulls and the remaining 30–40% to genomics if your herd is risk‑averse; invert that on your top genomic heifers if you prioritize maximum genetic gain.
    1. Make sure each mating segment explicitly matches your herd’s economics (milk pricing, fat/protein premiums) and management style (grazing vs housed, robot vs parlor).

Key Takeaways:

  • The 24P:14F TPI 2026 protein flip turns Powerhouse (+119 TPI) into a proven winner and knocks fat-heavy bulls like Garza (−125 TPI) down a tier, so your semen mix needs a hard audit. 
  • All 10 genomic USA Holstein TPI leaders in April 2026 are new names within a 37‑point band, which means rank 1 vs rank 10 is noise, and you should buy portfolios, not “the” bull. 
  • Proven sires like Sheepster (+3480 TPI), Powerhouse, Captain, and Elgin still anchor the list with 95–99% reliabilities, trading 150–250 TPI points for far less re‑ranking risk on cows and ET work. 
  • For high‑input herds, Woodford/Jitters/Sabotage‑type genomics align top‑end TPI with +1,000+ NM$, while grazing and fertility‑sensitive herds should lean into health‑tilted sires and cap big‑milk, tougher‑fertility bulls. 
  • Red & White programs now pivot around Okafor‑Red/Ocean‑Red for index and Crypto PP/RC PTAT sires for show type, forcing you to pick where each Red mating sits on the profit‑vs‑pretty spectrum.

UK April 2026 PLI Proofs: Lorenzo +874, Powerhouse #1 Proven – and Why Type Merit Shows Zero Overlap

Wednesday, April 8th, 2026

Lorenzo just landed at +874 PLI while Powerhouse quietly took #1 proven — but the only bulls that balance PLI, TM, feet, and fertility are sitting well outside the headlines

Executive Summary: Lorenzo just landed at +874 PLI in the April 2026 UK run, while 70% of the genomic top 10 turned over, and not one of them appears in the TM genomic top 100. That means the bulls driving £PLI in the UK right now are mostly negative or marginal for Type Merit, so if you’re picking only off the PLI list, you’re probably not prioritizing udders and feet while chasing milk and health. On the proven side, Powerhouse moved to +768 PLI at #1, Severus crashed 168 points to +596, and MASERATI P jumped 80 points but brings -0.08 L&F, so some “safe” sires on old mating lists now look a lot riskier. The rare balanced sires — TROPHY at +769 PLI and +2.09 TM, Taos and RENEGADE with strong PLI, TM, and feet — sit just outside the headline slots and are easy to miss if you’re only scanning the top 10s. WWS now owns 7 of the top 10 proven TM spots off closely related Parfect/Renegade lines, which is great for type but a real inbreeding trap if your semen invoices already lean WWS-heavy. For your herd, this run says: cap exposure to any single genomic PLI rocket, audit how many cows are still booked to big droppers like COYOTE P and ALTAVALUEPACK, and make sure at least a few of your main sires live in the small overlap where PLI, TM, fertility, and feet all point in the same direction.

UK April 2026 PLI

Seven of the top 10 genomic PLI positions turned over between December 2025 and April 2026 in the UK evaluation — one of the highest-churn runs in recent memory. DENOVO 22750 LORENZO, a brand-new entrant at +874 PLI (April 2026 UK evaluation, 66% reliability), seized the #1 genomic spot from DENOVO COYOTE P, who cratered 62 points from +871 to +809 PLI and fell from first to 13th. Meanwhile, PEAK POWERHOUSE climbed to #1 daughter-proven at +768 PLI (April 2026 UK evaluation, 78% reliability), displacing OCD TROOPER SHEEPSTER, who dropped 72 points.

But here is the run’s most provocative signal: the PLI and Type Merit indexes are pulling in opposite directions at the genomic level. Lorenzo’s +874 PLI comes with a -0.21 Type Merit. OCD MANNY, the new #1 Type Merit genomic bull at +2.90 TM (April 2026 UK evaluation, 53% TM reliability), carries just +662 PLI — too low to crack the PLI top 100. Zero bulls appear in both the PLI genomic top 10 and the Type Merit genomic top 100. For breeders who care about both production economics and structural longevity, this divergence demands attention.

What Changed at the PLI Genomic Top?

The December 2025 PLI genomic top 10 was tightly bunched: the #1-to-#10 spread was just 26 points (871 down to 845). April 2026 blew that band open to 58 points (874 down to 816), with only three bulls surviving from the previous top 10.

The three survivors all dropped: ADAWAY BEYOND FAITHFUL fell 33 points, COLUMBIA lost 45, and DAY TRIP slid 54 points between December 2025 and April 2026. When the anchors decline, and the new entrants arrive untested, breeders should treat this top group as a hypothesis, not a verdict.

The Big Movers: Up, Down, and Out

Biggest Drops Inside the PLI Genomic Top 100

The most consequential movement happened outside the top 10. Several bulls that were generating heavy semen demand in late 2025 took significant hits:

BullDec 2025 Rank (UK PLI)Dec 2025 PLIApr 2026 Rank (UK PLI)Apr 2026 PLIChange
DENOVO COYOTE P A2A2187113809-62

PEAK ALTAMAXIMINO KCBB1583292723-109
PEAK ALTAREGALCROWN31816Dropped out——
PEAK ALTACASANOVA72768Dropped out——

COYOTE P’s fall — from #1 at +871 PLI (December 2025 UK evaluation) to #13 at +809 PLI (April 2026 UK evaluation) — is a textbook reminder of what 66% reliability means in practice. Sixty-two points of movement in a single run. ALTAVALUEPACK’s 94-point decline from #7 to #49 is even sharper. ALTAMAXIMINO’s 109-point plunge from #15 to #92 dropped it from a semen-demand hot list to borderline irrelevance in one evaluation cycle.

Three Alta bulls (AltaValuepack, AltaMaximino, AltaRegalcrown) took the heaviest damage in this run. This pattern could reflect daughter data accumulating in a direction that doesn’t match the genomic prediction, or it could reflect the normal variance associated with sub-70% reliabilities. Either way, any breeder who loaded mating lists with these bulls in Q1 2026 should audit their exposure.

Risers to Watch

Not everything moved down. A few bulls that were already in the December 2025 list held their ground or entered with strong profiles:

  • PEAK ALTATALLTALE entered at #11 (+815 PLI, April 2026 UK evaluation, 66% reliability) with a balanced TM of +0.54 and +0.61 Mammary — one of the few new PLI top-20 entrants carrying positive conformation.
  • DENOVO 20771 SEGMENT A2A2 held at #12 (+812 PLI, April 2026 UK evaluation), essentially stable from December’s +844 at #11. A 32-point decline, but modest relative to the carnage around it.
  • OCD SHEEPSTER MIKE is the most interesting new PLI top-10 arrival from a dual-purpose perspective: +828 PLI (April 2026 UK evaluation, 67% reliability) with +1.16 TM, +0.83 Mammary, +1.66 Legs & Feet, and +1.59 Locomotion. That combination of structural soundness and high PLI is rare at this level.

What PLI Is Rewarding This Run

The April 2026 PLI genomic top group has tilted decisively toward production and health economics at the expense of conformation. Across the top 3 bulls:

  • Average Milk: +723 kg (Lorenzo +953, AltaRotation +745, AltaVaughn +471, April 2026 UK evaluation)
  • Average TM: -0.21 to +0.76 — two of three carry negative or barely positive Type Merit
  • Average Mammary: -0.14 to +0.54 — Lorenzo and AltaRotation both carry negative Mammary composites, AltaVaughn is modestly positive
  • Average Fertility Index: +137 to +174 — strong reproductive values for all three

Compare that to December 2025’s top 3 (Coyote P, Day Trip, Preston), which averaged +940 kg of Milk but carried modestly higher TM scores (+0.76, -0.40, +0.93, respectively, in the December 2025 UK evaluation). The shift isn’t dramatic in production volume, but the conformation trade-off has steepened. Lorenzo and AltaRotation both carry negative TM values (-0.21 each, April 2026 UK evaluation), meaning breeders selecting on PLI alone are now actively pulling Type Merit backward at the very top of the ranking.

The Legs & Feet and Locomotion picture has also shifted. Lorenzo carries +0.82 L&F and +0.86 Locomotion — adequate. AltaRotation carries just +0.08 L&F and +0.13 Locomotion. For robotic milking herds where foot health directly impacts fetch rates, AltaRotation’s PLI rank may overstate his practical value.

How Volatile Are the UK’s PLI Genomic Rankings Right Now?

The 70% top-10 turnover rate and the band expansion from 26 points to 58 points are the two numbers that matter most for calibrating confidence in this run.

When 7 of 10 positions turn over, and all 10 bulls carry 66–67% reliability, the ranking is better understood as a probability distribution than a fixed leaderboard. Lorenzo at +874 PLI is the best current estimate of his genetic merit — but at 66% reliability, his true value could plausibly sit anywhere in a range of roughly ±50 PLI points. That means he could be a +924 bull or a +824 bull, and we won’t know for several more runs.

The three surviving anchors all moved down (FAITHFUL -33, COLUMBIA -45, DAY TRIP -54), which suggests the December 2025 genomic top group was slightly inflated relative to where the data settled in April 2026. This is normal genomic regression, not a system failure — but it reinforces why single-run PLI rankings should never be treated as definitive sire selection tools in isolation.

Key risk metric: Every bull in the PLI genomic top 10 has a reliability below 70%. No exceptions. Treat accordingly.

Whether this 70% churn rate is historically elevated or within normal UK genomic variance would require a multi-run comparison; that’s a trend line we’ll track in future proof-run coverage.

PLI Daughter-Proven: Powerhouse Takes #1 as Sheepster and Severus Fall Hard

The daughter-proven PLI list tells a more stable story — but still contains surprises. Seven of the December 2025 top 10 held their positions in April 2026, compared to just three on the genomic side. The proven top is anchored, but several high-profile bulls took heavy hits.

POWERHOUSE’s Rise to #1

PEAK POWERHOUSE gained 22 PLI points (+746 to +768, December 2025 to April 2026 UK evaluation) while most of his proven peers declined. At 78% reliability, he’s building confidence with each run. His profile is high-production, moderate-type: +1,111 kg Milk, +0.07 Fat %, +0.11 Prot %, but just +0.17 TM (April 2026 UK evaluation). His Mammary (+0.14) and Legs & Feet (+0.27) are minimal — he’s a PLI-efficiency bull, not a dual-purpose one.

GENOSOURCE CAPTAIN: The Quiet Climber

CAPTAIN’s +30 PLI gain (696 to 726, December 2025 to April 2026) on 98% reliability is arguably the most trustworthy number in the entire UK evaluation right now. At near-maximum reliability, his ranking is essentially final. His profile is balanced: +973 kg Milk, +1.09 Mammary, +0.73 Legs & Feet, +1.07 Locomotion, and +0.91 TM (April 2026 UK evaluation). Not flashy, but the data is done moving.

The Big Proven Losers

The December 2025 #1 and #2 both fell hard:

  • OCD TROOPER SHEEPSTER: -72 PLI (783 to 711, December 2025 to April 2026 UK evaluation), #1 to #3. His TM actually improved slightly (+1.07 to +1.22, December 2025 to April 2026), but production and health traits pulled his PLI down. At 79% reliability, this drop may stabilize — but the December #1 ranking now looks like the high-water mark.
  • PEAK ALTASEVERUS: -168 PLI (764 to 596, December 2025 to April 2026 UK evaluation), #2 to #22. This is the single largest PLI decline in the entire top group. ALTASEVERUS went from the second-highest proven bull in the UK to the 22nd in one run. At 88% reliability, this isn’t genomic noise — it’s daughter data correcting the prediction significantly downward. His TM moved from -2.64 (December 2025) to -2.53 (April 2026) — a marginal improvement but still deeply negative. Breeders who used Severus heavily in 2025 should review progeny performance.
  • PEAK ALTASOLACE: -111 PLI (683 to 572, December 2025 to April 2026 UK evaluation), #9 to #32. Another Alta proven bull with a triple-digit decline.
  • ALL.NURE WENDAT: -112 PLI (678 to 566, December 2025 to April 2026 UK evaluation), #10 to #35.

WINSTAR MASERATI P: The Biggest Proven Riser

MASERATI P surged 80 PLI points (585 to 665, December 2025 to April 2026 UK evaluation) to crack the top 10 at #8, jumping from #41 in December 2025. At 89% reliability, this gain carries weight. His profile is health-heavy: +0.38 SCC, +0.73 Mammary — solid for housed herds focused on cell count management — but his Legs & Feet of -0.08 is a red flag for any system where mobility matters. His TM of +0.55 and production of just +392 kg Milk mean he’s not a volume bull. He’s a cell-count-and-health play at a competitive PLI level, but herds needing structural soundness should look elsewhere.

Type Merit Genomic: OCD Manny Arrives at +2.90 TM — And the PLI Overlap Is Zero

The Type Merit genomic list runs on entirely different logic than PLI, and April 2026 makes that divergence impossible to ignore. OCD MANNY debuted at #1 with a +2.90 TM (53% TM reliability, April 2026 UK evaluation), the highest genomic Type Merit score in that evaluation. His PLI of +662 doesn’t appear in the PLI genomic top 100 (minimum threshold: +715 PLI, April 2026 UK evaluation).

Every returning bull dropped TM this run — no exceptions among the seven anchors. SYNERGY KICKSTART fell from #1 at +2.93 TM to #2 at +2.75, a -0.18 decline that also came with a -63 PLI drop (489 to 426, December 2025 to April 2026). MYSTIQUE ANIMATION took the steepest hit: -0.29 TM (2.75 to 2.46) and -75 PLI (460 to 385).

Three bulls exited the top 10. SHELAND PARFECT LOCK transitioned from the genomic TM list (#2 at +2.77 TM, December 2025, 71% PLI reliability) to the daughter-proven TM list (#6 at +2.42 TM, April 2026, 91% PLI reliability). His TM dropped 0.35 points during the genomic-to-proven transition — a useful reference point for anyone projecting how current genomic TM leaders might look once daughter data arrives.

What the TM Top Group Looks Like

The TM genomic top 10 is a conformation-first population. Average PLI across the top 10 is just +340 — less than half the PLI genomic top-10 average of +840. Five of the top 10 carry PLI below +400. CLWCH RHAPSODY EX90 at just +94 PLI would be essentially off the radar for any PLI-focused breeding program, despite being the UK’s #4 genomic Type Merit bull.

Mammary composites run high: OCD MANNY +2.99 MAM, MYSTIQUE ANIMATION +2.71, WALNUTLAWN PG BENSON +2.29 (April 2026 UK evaluation). Legs & Feet are likewise elevated, with MANNY at +1.73 L&F and BENSON at +2.16. These are structural bulls built for classification programs and longevity-first herds.

SMX dominates the TM genomic top 10, holding 5 of 10 positions (up from 4 in December 2025). CBL holds 2, with WWS, UKD, and ALT each at 1.

Type Merit Daughter-Proven: Rimrock Takes #1 as WWS Locks Down 7 of 10 Spots

The Type Merit daughter-proven list saw dramatic reshuffling. BOMAZ RIMROCK RDC, a GEN bull, rose to #1 at +2.88 TM (89% TM reliability, April 2026 UK evaluation). He was #20 in December 2025 at +2.33 TM — a gain of +0.55 TM points as daughter data accumulated.

The December 2025 TM DP #1, SANDY-VALLEY ESQUIRE (+3.02 TM, December 2025 UK evaluation), dropped out of the top 100 of the April 2026 dedicated Type Merit DP. AOT HAMPSHIRE, December’s #2 at +3.00 TM, fell to #3 at +2.63 TM (-0.37). SIEMERS RENGD PARFECT slipped from #3 at +2.97 to #2 at +2.74 (-0.23 TM).

The defining feature of the April 2026 TM DP top 10 is WWS’s dominance: 7 of the top 10 positions are WWS-marketed bulls. Positions #2 through #9 are all either Siemers, Sheland Parfect Lock, Winstar Parfect Cirrus P, AOT Parfect Harmony, Regan-Danhof Capone, or S-S-I PR Renegade — all distributed by WWS. The Parfect/Renegade bloodlines are heavily represented, suggesting concentration risk for herds sourcing exclusively from this list.

LEANINGHOUSE TAOS, at #13 on the TM DP list (+1.98 TM, 95% TM reliability, April 2026 UK evaluation) and #15 on the PLI DP list (+613 PLI, 96% reliability, April 2026), is one of the few daughter-proven bulls that appears near the top of both rankings — a genuine dual-index performer with the reliability to back it up.

The Cross-Index Divergence: PLI and Type Merit Are Selecting for Different Animals

This is the structural story of the April 2026 UK evaluation, and it warrants explicit treatment.

Genomic: Zero Overlap

Not a single bull in the PLI genomic top 10 appears in the Type Merit genomic top 100. Not a single bull in the TM genomic top 10 appears in the PLI genomic top 100. The two indices are selecting entirely non-overlapping populations at the extremes.

PLI Genomic #1 (Apr 2026 UK PLI)TM Genomic #1 (Apr 2026 UK TM)

Production-first, negative conformationConformation-first, moderate production
66% PLI reliability53% TM reliability
GENSMX

The best cross-index genomic performer in the April 2026 evaluation is TROPHY A2A2 (+769 PLI at genomic rank #46, +2.09 TM at TM rank #29, April 2026 UK evaluation). He carries +504 kg Milk, +2.54 Mammary, +2.04 Legs & Feet, +2.01 Locomotion, and a Fertility Index of +174 — the rare bull who doesn’t force breeders to choose between PLI and Type Merit. His AI company, SYN, may limit availability in some markets.

BEYOND HI-PACE (+722 PLI at #93, +1.93 TM at #39, April 2026 UK evaluation) is another dual-index bull with +1.35 Mammary, +1.01 L&F, and +0.99 Locomotion, though his PLI sits near the bottom of the top 100 and his TM is mid-pack.

Daughter-Proven: Slightly More Overlap, But Still Divergent

At the proven level, the gap narrows slightly:

  • LEANINGHOUSE TAOS: PLI DP #15 (+613 PLI, 96% reliability), TM DP #13 (+1.98 TM, 95% reliability), April 2026 UK evaluation. The most balanced proven bull in the UK system right now. His +1.79 Mammary, +2.42 Legs & Feet, and +2.87 Locomotion make him a standout structural sire, while +896 kg Milk and strong health traits keep his PLI competitive.
  • S-S-I PR RENEGADE: PLI DP #27 (+583 PLI, 98% reliability), TM DP #9 (+2.25 TM, 99% reliability), April 2026 UK evaluation. Near-maximum reliability on both indexes. His +1.54 Mammary, +2.41 L&F, and +2.81 Locomotion are elite linear scores with legitimate PLI backing.
  • PEAK POWERHOUSE (PLI DP #1, +768 PLI, April 2026 UK evaluation) carries just +0.17 TM — not in the TM DP top 100.
  • BOMAZ RIMROCK RDC (TM DP #1, +2.88 TM, April 2026 UK evaluation) carries just +374 PLI — not in the PLI DP top 100.

The divergence is less extreme among proven bulls than genomics, but the principle holds: the #1 on each index doesn’t rank on the other.

AI Companies and Bloodlines: Who Owns the Top and What Changed

PLI Genomic Top 10

GEN53↓
SMX21↓
ALT22—
CBL02↑
WWS12↑

GEN’s December dominance (5 of 10) contracted to 3 of 10 in April. CBL entered the top 10 for the first time with GENOSOURCE JUDO (#5) and OCD THORSON RIPCORD (#8). ALT held two spots, but both are untested first-run bulls (AltaRotation, AltaVaughn) — fragile positions. WWS gained through OCD SHEEPSTER MIKE and BADGER SIEMERS DAY TRIP.

PLI Daughter-Proven Top 10

The proven list is more diversified: WWS (3), CBL (2), GEN (2), UKD (1), SMX (1), ALT (0 — a notable absence from the proven top 10 given Alta’s heavy genomic marketing).

Type Merit Genomic Top 10

SMX dominates with 5 of 10 positions. For classification-focused breeders, SMX is the primary semen source at the genomic level. CBL holds 2 spots.

Type Merit Daughter-Proven Top 10

WWS controls 7 of 10 positions — the most concentrated company share across any of the four rankings. The Parfect/Renegade family line runs through multiple bulls in this group (Siemers Rengd Parfect, Sheland Parfect Lock, Winstar Parfect Cirrus P, AOT Parfect Harmony). Herds building mating lists exclusively from the TM DP top 10 risk significant bloodline overlap. Cross-referencing pedigrees before committing to multiple WWS type bulls from this list is essential.

What This Means for Your Matings This Season

For Housed, High-Input Herds Prioritizing PLI

If your breeding goal is maximum economic index in a housed TMR system, LORENZO (+874 PLI, April 2026 UK evaluation), ALTAROTATION (+867 PLI), and HOTSHOT (+846 PLI) sit at the top — but all carry 66% reliability and negative or barely positive TM. Use them as part of a diversified sire portfolio, not as blanket picks. Limit any single genomic bull to no more than 15–20% of matings until reliability crosses 75%.

If you want PLI with proven confidence, GENOSOURCE CAPTAIN (+726 PLI, 98% reliability, April 2026 UK evaluation) is the safest bet in the entire UK evaluation. His numbers aren’t moving. PEAK POWERHOUSE (+768 PLI, 78% reliability, April 2026) offers higher PLI but with less certainty.

For Grazing and Lower-Input Systems

Grazing herds that need moderate production with strong fertility and structural soundness should look at TROPHY A2A2 (+769 PLI, +2.09 TM, Fertility Index +174, +2.54 Mammary, +2.04 L&F, +2.01 Locomotion, April 2026 UK evaluation). He’s the best cross-index genomic bull in this run and carries the kind of balanced profile that holds up on pasture. His SYN distribution may require proactive sourcing.

At the proven level, LEANINGHOUSE TAOS (+613 PLI, +1.98 TM, 96% PLI reliability, 95% TM reliability, April 2026 UK evaluation) is the standout. His daughter’s proof is essentially confirmed, his Legs & Feet (+2.42) and Locomotion (+2.87) are outstanding for grazing longevity, and his +1.79 Mammary supports functional udder quality alongside +896 kg Milk.

If you’re running robots, screen for Mammary and Legs & Feet first, PLI second. OCD SHEEPSTER MIKE (+828 PLI, +1.16 TM, +0.83 Mammary, +1.66 L&F, +1.59 Locomotion, April 2026 UK evaluation) is the clear genomic standout for robot herds — strong enough PLI to justify the pick, with the foot and leg traits that reduce fetch failures. His Mammary at +0.83 is adequate though not elite; pair him with high-MAM maternal lines where udder attachment needs reinforcement.

If your herd’s primary bottleneck is udder conformation rather than locomotion, ADAWAY BEYOND FAITHFUL(+827 PLI, +1.23 TM, +1.50 Mammary, +0.63 L&F, +0.73 Locomotion, April 2026 UK evaluation) offers better Mammary but weaker feet — a different trade-off that suits herds where locomotion is already under control.

Among proven bulls, S-S-I PR RENEGADE (+583 PLI, +2.25 TM, 98% PLI reliability, +1.54 Mammary, +2.41 L&F, +2.81 Locomotion, April 2026 UK evaluation) combines elite structural proof with legitimate PLI backing for herds that can accept a lower PLI floor in exchange for near-certainty on feet and legs.

For Type and Classification Programs

If your primary goal is classification and a show-oriented type while keeping PLI respectable, OCD MANNY (+2.90 TM, +662 PLI, April 2026 UK evaluation) is the genomic TM leader but comes with a PLI trade-off compared with the extreme PLI bulls. His +2.99 Mammary is the highest in the TM top 10. Use him for targeted structural matings, not as a universal sire of sons.

If your herd needs type but can’t give up too much PLI, SYNERGY KICKSTART (+2.75 TM, +426 PLI, April 2026 UK evaluation) is the second-highest genomic TM bull, but his PLI of +426 is a substantial economic penalty. Reserve him for cows where conformation needs outweigh production targets.

At the proven level, BOMAZ RIMROCK RDC (+2.88 TM, +374 PLI, 89% TM reliability, April 2026 UK evaluation) is a high-confidence type sire. His Red Carrier status opens crossbreeding flexibility. SIEMERS RENGD PARFECT(+2.74 TM, +418 PLI, 95% TM reliability, April 2026) offers slightly more PLI with near-maximum type reliability.

For Beef-on-Dairy Cull Programs

If you’re using beef-on-dairy on the bottom of your herd, you want the remaining dairy matings concentrated on the highest-PLI or highest-TM bulls appropriate to your goals — and aligned with this run’s data. Any cow still allocated to ALTASEVERUS (now +596 PLI, April 2026 UK evaluation, down from +764 in December 2025) or ALTASOLACE (+572 PLI, April 2026, down from +683) should be reassigned before the next breeding round.

30-Day Action Item

Pull your current UK mating list and cross-check every sire against the April 2026 PLI and Type Merit rankings. Specifically:

  1. Flag any bull that dropped >50 PLI points this run — particularly COYOTE P (-62), PRESTON (-62), ALTAVALUEPACK (-94), and ALTAMAXIMINO (-109). Review remaining inventory allocation before your next mating cycle.
  2. Audit bloodline concentration in your WWS type bulls if you source heavily from the TM DP list. Seven of the top 10 TM DP bulls are distributed by WWS and share overlapping Parfect/Renegade pedigrees.
  3. Rebalance your PLI-to-TM mix. If you’ve been selecting purely on PLI, the April 2026 top group is pushing TM backward. For herds that need structural maintenance alongside economic gain, consider adding TROPHY, SHEEPSTER MIKE, or FAITHFUL as dual-purpose anchors.

Key Takeaways:

  • Lorenzo debuts at +874 PLI and drives a 70% turnover in the UK genomic top 10, but none of those bulls make the TM genomic top 100, so pure-PLI selection now pushes type backward.
  • On the proven list, Powerhouse climbs to +768 PLI at #1 while Severus drops 168 points and MASERATI P rises to +665 PLI with -0.08 L&F, making several “trusted” sires much higher risk than they looked last run.
  • The best all‑rounders sit off the front page: TROPHY (+769 PLI, +2.09 TM), Taos and RENEGADE combine strong PLI, TM, and feet, and are the bulls most likely to keep both your milk cheque and your cull list happy.
  • WWS controls 7 of the top 10 proven TM spots off Parfect/Renegade blood, which is great for type but dangerous for inbreeding if a WWS-heavy semen bill is already running through your TMR herd.
  • Action this run: cap exposure to any one genomic PLI rocket, pull any leftover Severus/ALTAVALUEPACK/COYOTE P from routine matings, and make sure each herd segment has at least one sire where PLI, TM, fertility, and legs all point the same way.

April 2026 Canada Holstein LPI & Pro$ -PARFECT Takes #1 from ROZLINE as ROZLINE Loses 626 Pro$ and PATTERN Drops 237

Tuesday, April 7th, 2026

The Pro$ ceiling dropped ~250 points for most top bulls. If your sire lineup hasn’t changed since December, your income math has.

Executive Summary: ROZLINE just lost 626 Canada Pro$ in one run (from +2664 in December 2025 to +2038 in April 2026), while PARFECT quietly gained 58 Canada LPI points to take #1 at +3914. PATTERN stays #1 on Canada Pro$ at +2974 but gives back 237 Pro$, and CABO trims 231 Pro$ to sit at +2877, which means the Pro$ ceiling on proven sires dropped ~200–250 points for most front‑end bulls. That’s a different risk picture if you’re budgeting semen off last run’s income numbers or counting on single‑bull exposure to carry your Pro$ average. The daughter‑proven LPI and Pro$ top 10s are still anchored by many of the same names, but the big Pro$ hits to ROZLINE and GRAZIANO and the new arrival of POWERSTAR at +2854 Pro$ show how quickly “go‑to” bulls can be repriced. Genomic GPA LPI and GPA Pro$ lists remain volatile, with new bulls rotating through the top 10, so stacking too many matings on a couple of young sires is still a higher‑beta play. If your herd prioritizes income, robot‑friendly type, or inbreeding control, this run gives you clear signals on which proven sires to keep as anchors, which to demote to niche roles, and where Red/polled or alternative‑family outcrosses can keep your milk cheque and future mating options safer.

In the April 2026 Canada Holstein proof run, SIEMERS RENGD PARFECT‑ET moves to #1 on Canada LPI at +3914 (Canada Holstein LPI, April 2026) after sitting at +3856 and #5 in December 2025 (Canada Holstein LPI, December 2025). At the same time, PROGENESIS PATTERN stays #1 on Canada Pro$ at +2974 (Canada Holstein Pro$, April 2026) but drops 237 Pro$ from +3211 (Canada Holstein Pro$, December 2025). The bigger hit belongs to SIEMERS RENEGADE ROZLINE‑ET: he falls from +2664 to +2038 (Canada Holstein Pro$, December 2025 vs April 2026), a −626 Pro$ change, and from +3947 to +3810 on Canada LPI, sliding from #1 to #9 (Canada Holstein LPI, December 2025 vs April 2026).

For elite breeders and AI programs, this April 2026 Canada Holstein run matters because it compresses the top of both Canada LPI and Pro$ rankings, trims the income ceiling on several headline bulls, and shifts which sires you should treat as portfolio anchors vs. specialists over the next 6–12 months. The daughter‑proven front edge looks more stable than the genomic lists, but the magnitude and pattern of Pro$ changes still carry real implications for how you weight income vs type at the very top.

What Changed at the Top?

On the daughter‑proven side, SIEMERS RENGD PARFECT‑ET moves from +3856 (Canada Holstein LPI, December 2025, rank #5) to +3914 (Canada Holstein LPI, April 2026, rank #1), gaining 58 LPI and jumping four spots. STANTONS REMOVER PP moves from +3831 (Canada Holstein LPI, December 2025, rank #9) to +3873 (Canada Holstein LPI, April 2026, rank #2), a +42 LPI move that pushes him into the top pair. December 2025’s #1, SIEMERS RENEGADE ROZLINE‑ET, drops from +3947 to +3810 (Canada Holstein LPI, December 2025 vs April 2026), losing 137 LPI and landing at #9 in April 2026.

PEAK ALTAINSCAPE‑ET shifts from +3897 (Canada Holstein LPI, December 2025, rank #2) to +3829 (Canada Holstein LPI, April 2026, rank #7), −68 LPI, and WINSTAR MELBY‑P‑ET moves out of the April 2026 LPI top 10 from +3838 (Canada Holstein LPI, December 2025, rank #7 tied), though he remains in the top 100. Overall, roughly seven of the December 2025 Canada Holstein LPI top 10 still sit in or immediately around the top 10 in April 2026, with 3–4 bulls rotating in and out.

On Canada Pro$, PROGENESIS PATTERN holds #1 but drops from +3211 to +2974 (Canada Holstein Pro$, December 2025 vs April 2026), a −237 Pro$ change. DENOVO 16034 CABO‑ET stays #2 but falls from +3108 to +2877 (Canada Holstein Pro$, December 2025 vs April 2026), −231 Pro$. A new face, PEAK POWERSTAR‑ET, appears at +2854 (Canada Holstein Pro$, April 2026, rank #3) after not featuring in the December 2025 Pro$ top 100, while December 2025’s #3, WINSTAR GRAZIANO‑ET, drops from +3099 to +2655 and from #3 to #81 tied (Canada Holstein Pro$, December 2025 vs April 2026).

The headline shift is clear: the LPI front is reshuffled but still anchored by broadly similar bulls, while the Pro$ ceiling has been lowered by roughly 200–250 points for most top‑end sires, with ROZLINE and GRAZIANO seeing much larger income hits.

  • Role: polled, high‑milk, high‑component proven bull who remains a Pro$ factor even after a trim; ideal where polled is non‑negotiable, and income still matters.

PEAK POWERSTAR‑ET

  • Pro$: not in December 2025 Canada Holstein Pro$ top 100 → +2854 (Canada Holstein Pro$, April 2026, rank #3), new entrant.
  • LPI: +3406 (Canada Holstein LPI, April 2026).
  • Trait profile (April 2026): +695 Milk, +109 Fat, +72 Protein, +0.55%F, +0.29%P, +4 Conf, HL 105, DCA 104 (Canada Holstein Pro$ & LPI, April 2026).
  • Role: daughter‑proven Pro$ newcomer with components, decent type and health, suited as an income sire with workable conformation.

Droppers

SIEMERS RENEGADE ROZLINE‑ET

  • LPI: +3947 (Canada Holstein LPI, December 2025, rank #1) → +3810 (Canada Holstein LPI, April 2026, rank #9), −137 LPI.
  • Pro$: +2664 (Canada Holstein Pro$, December 2025) → +2038 (Canada Holstein Pro$, April 2026), −626 Pro$.

  • Role: now a specialist type bull with strong components; better reserved for type/show and high‑type cow families than for pure income roles.

PROGENESIS PATTERN

  • Pro$: +3211 (Canada Holstein Pro$, December 2025, rank #1) → +2974 (Canada Holstein Pro$, April 2026, rank #1), −237 Pro$.
  • LPI: +3829 (Canada Holstein LPI, December 2025, rank #10) → +3766 (Canada Holstein LPI, April 2026, rank #15), −63 LPI.
  • Trait profile (April 2026): +1199 Milk, +106 Fat, +71 Protein, +0.47%F, +0.23%P, +3 Conf, HL 108, DCA 104.
  • Role: still the Pro$ reference bull but now as part of a compressed top tier; an income anchor with sufficient type and health for large, efficiency‑driven herds.

DENOVO 16034 CABO‑ET

  • Pro$: +3108 (Canada Holstein Pro$, December 2025, rank #2) → +2877 (Canada Holstein Pro$, April 2026, rank #2), −231 Pro$.
  • LPI: +3707 (Canada Holstein LPI, December 2025, rank #33) → +3611 (Canada Holstein LPI, April 2026, rank #32), −96 LPI.
  • Trait profile (April 2026): +685 Milk, +117 Fat, +73 Protein, +0.56%F, +0.27%P, 0 Conf.
  • Role: a fat‑driven Pro$ sire with modest type; still high‑band for income but now more clearly a components specialist.

WINSTAR GRAZIANO‑ET

  • Pro$: +3099 (Canada Holstein Pro$, December 2025, rank #3) → +2655 (Canada Holstein Pro$, April 2026, rank #81 tied), −444 Pro$.
  • LPI: +3707 (Canada Holstein LPI, December 2025, rank #33) → +3564 (Canada Holstein LPI, April 2026, rank #56), −143 LPI.
  • Trait profile (April 2026): +683 Milk, +125 Fat, +47 Protein, +1.33%F, +0.58%P, 0 Conf, HL 104, DCA 104.
  • Role: still attractive where very high fat % and good management traits are prioritized; no longer a top‑band Pro$ pick for general use.

What Canada LPI and Pro$ Are Rewarding This Run

The April 2026 Canada Holstein LPI top group is rewarding production and components with strong, but not necessarily extreme, type. PARFECT at +3914 (Canada Holstein LPI, April 2026) shows +894 Milk, +85 Fat, +57 Protein, +0.39%F, +0.19%P, +10 Conf, MS +4, FL +15, DS +7 — a balanced yield and type profile. STANTONS REMOVER PP at +3873 (Canada Holstein LPI, April 2026) pushes more volume with +1793 Milk, +113 Fat, +81 Protein, +0.36%F, +0.23%P, +8 Conf, MS +5, FL +9. DUCKETT PFCT HAS IT ALL‑ET at +3843 (Canada Holstein LPI, April 2026) runs +2294 Milk, +52 Fat, +65 Protein, +0.30%F, +0.10%P, +15 Conf, MS +10, FL +10, DS +16, clearly prioritizing volume and show‑type.

On Canada Pro$, April 2026 favors bulls that convert fat and protein into net income with a solid, workmanlike type. PATTERN at +2974 (Canada Holstein Pro$, April 2026) sits at +1199 Milk, +106 Fat, +71 Protein, +0.47%F, +0.23%P, +3 Conf, HL 108, DCA 104. CABO at +2877 (Canada Holstein Pro$, April 2026) is +685 Milk, +117 Fat, +73 Protein, +0.56%F, +0.27%P, 0 Conf. POWERSTAR at +2854 (Canada Holstein Pro$, April 2026) combines +695 Milk, +109 Fat, +72 Protein, +0.55%F, +0.29%P, +4 Conf, HL 105, DCA 104.

Three contrasting case studies spell out the trade‑offs:

  • PAZZLE (SIEMERS RZ PAZZLE 34954‑ET)
    +3810 (Canada Holstein LPI, April 2026), +2038 (Canada Holstein Pro$, April 2026), +16 Conf.
    +191 Milk, +145 Fat, +34 Protein, +1.16%F, +0.23%P, MS +5, FL +13, DS +16.
    Trade‑off: extreme type and fat %, solid but mid‑band Pro$ — excellent for show‑leaning programs that still care about components.
  • DUCKETT PFCT HAS IT ALL‑ET
    +3843 (Canada Holstein LPI, April 2026), +1960 (Canada Holstein Pro$, April 2026), +15 Conf.
    +2294 Milk with moderate components and strong MS/FL — big‑volume, high‑type, mid‑Pro$.
    Trade‑off: ideal for herds that monetize type and pedigree; less suited as a primary income sire.
  • PROGENESIS PATTERN
    +2974 (Canada Holstein Pro$, April 2026), +3766 (Canada Holstein LPI, April 2026), +3 Conf.
    +1199 Milk, +106 Fat, +71 Protein, strong health composite.
    Trade‑off: less eye‑catching than the extreme type bulls, but a more efficient income engine for commercial‑style and large herds.

In short, April 2026 Canada LPI still pays strongly for type and functional conformation when coupled with components, while Canada Pro$ is unforgiving about the income math and will only carry high‑type bulls when their fat/protein profiles justify it.

Stud Power, Family Power, and Outcross Space

AI stud codes in the April 2026 Canada Holstein lists show a familiar pattern. Semex 200 code bulls (PROGENESIS PATTERN, PROGENESIS MONTREAL, PROGENESIS MONTEVERDI, PROGENESIS PRAGMATIC, and others) occupy multiple slots in both the LPI and Pro$ top 100 lists. Codes 0007, 0011, and 0029 (Select, Alta/Peak, and related groups) are also heavily represented: PEAK ALTAINSCAPE‑ET, PEAK ALTACRAZE‑ET, PEAK ALTAHOTHAND‑ET, PEAK POWERSTAR‑ET, and a large set of genomic BEYOND/SHEEPSTER and Rosemary‑line bulls lead the young‑sire lists.

Bloodline concentration is particularly evident in the top 100 genomic by GPA LPI and GPA Pro$. SIEMERS SSI ROSMRY TONKS‑ET leads GPA LPI at +4179 in April 2026 (Canada Holstein GPA LPI, April 2026), with several other Rosemary‑line sires close behind. On GPA Pro$, SIEMERS RIM COBOT‑ET at +3755 and KENYON‑HILL OLYOP‑ET at +3732 (Canada Holstein GPA Pro$, April 2026) again tie back into a handful of sire stacks.

Within the daughter‑proven lists, genuine outcross space still exists:

  • DROUNER KL AUGUSTUS P RED at +3786 (Canada Holstein LPI, April 2026) and +2145 (Canada Holstein Pro$, April 2026) brings a Dutch Red, polled, alternative pedigree into the top 100.
  • KOEPON OH ROBIN RED at +3576 (Canada Holstein LPI, April 2026) and +2302 (Canada Holstein Pro$, April 2026) offers another competitive Red option with different bloodlines from the main Renegade/Parfect and BEYOND/SHEEPSTER clusters.

For ET and AI programs heavily invested in Renegade/Parfect, BEYOND, and related families, these Red and polled proven bulls — plus a handful of non‑cluster foreign codes — are where the practical outcross opportunities live, even if they sit 1–2 index tiers below the absolute top of LPI or a couple hundred Pro$ points below PATTERN/CABO.

How Volatile Are Canada’s LPI and Pro$ Rankings Right Now?

Between December 2025 and April 2026, the daughter‑proven Canada Holstein LPI and Pro$ lists show more compression than chaos. Around seven of the December 2025 LPI top‑10 bulls remain in or near the top 10 in April 2026, and a similar proportion holds for Pro$, with PATTERN, CABO, REMOVER PP, ALTAHOTHAND‑ET, and others still occupying high ranks despite level changes. The top‑end Pro$ bulls mostly lose 200–250 points (PATTERN −237 Pro$, CABO −231 Pro$, ALTAINSCAPE −245 Pro$), while ROZLINE and GRAZIANO see much larger drops (−626 and −444 Pro$ respectively).

Reliabilities for these leading daughter‑proven sires are high and in the mid‑ to high‑90s for production and conformation in both runs, as shown in the official lists. For bulls like PATTERN, PARFECT, CABO, REMOVER PP, ALTAINSCAPE, and GRAZIANO, these shifts are less about sampling noise and more about model and economic rebalancing across traits. That’s important: a 200‑point Pro$ or 60‑point LPI change signals a reset in how the index values their trait mix, but it doesn’t make existing daughters suddenly “wrong.”

The genomic lists are more volatile. OCD MILAN‑ET at +4137 (Canada Holstein GPA LPI, December 2025) gives way to SIEMERS SSI ROSMRY TONKS‑ET at +4179 (Canada Holstein GPA LPI, April 2026), with several bulls rotating in and out of the top 10. On GPA Pro$, PEAK ALTAPURPOSE‑ET at +3947 (Canada Holstein GPA Pro$, December 2025) is replaced by SIEMERS RIM COBOT‑ET at +3755 and a different mix of bulls in the +3700–3800 band (Canada Holstein GPA Pro$, April 2026). With no or very few Canadian daughters behind these bulls, this volatility is precisely the risk premium you should expect from genomic evaluations.

For portfolio planning, treat the daughter‑proven LPI and Pro$ front edge as relatively stable anchors and the genomic lists as higher‑beta tools where you spread risk across several bulls rather than betting heavily on any single name.

What This Means for Your Matings This Season

This is the section where April 2026 turns into decisions.

High-Input, Housed, Income-Driven Herds

If your herd prioritizes net income per cow in high‑input, housed systems, your starting point is Canada Holstein Pro$.

  • If your herd prioritizes maximum Pro$ with solid type, keep PROGENESIS PATTERN (+2974, Canada Holstein Pro$, April 2026) and DENOVO 16034 CABO‑ET (+2877, Canada Holstein Pro$, April 2026) as key anchors, and add PEAK POWERSTAR‑ET (+2854, Canada Holstein Pro$, April 2026) as a new proven income sire.
  • If your herd already relies on bulls that lost >250 Pro$ — ROZLINE (−626), GRAZIANO (−444), REMOVER PP (−299), ALTAINSCAPE (−245) — keep using them, but narrow them to matings where their specific strengths (type, fat %, polled, or other traits) justify the reduced Pro$.

Within 30 days, pull your active service list and flag every bull that dropped more than 250 Canada Holstein Pro$ between December 2025 and April 2026; for each, decide whether he remains a mainline income sire or becomes a targeted, trait‑specific option.

Robot Herds and Udder/Feet Priority

If your herd is on robots or runs high milking frequency with tight udder/feet requirements, you’ll put more weight on Canada Holstein LPI and Conformation.

  • If your herd prioritizes functional type with good components, look hard at PARFECT (+3914 LPI, +10 Conf, Canada Holstein LPI & Conformation, April 2026) and ALTAHOTHAND‑ET (+3853 LPI, +10 Conf, MS +7, FL +10, Canada Holstein LPI & Conformation, April 2026) as daughter‑proven anchors.
  • If your herd wants type with enough Pro$ to keep the accountant calm, PAZZLE (+3810 LPI, +2038 Pro$, +16 Conf) and HAS IT ALL (+3843 LPI, +1960 Pro$, +15 Conf) give you show‑influenced cows that still rank decently on Pro$.

Be cautious using low‑Conf, low‑MS bulls as day‑to‑day sires in robot herds, even when they’re high on Pro$. PATTERN, CABO, and POWERSTAR are all safe on that front; some other high‑Pro$ bulls are not.

Type/Show-Focused Programs

If you live off classification sheets, sales, and show results, this run confirms that the Canada Holstein Conformation list is stable and well-stocked.

  • If your herd prioritizes maximum Conformation, bulls like MATTENHOF HARRIS (+18 Conf, +278 Pro$, Canada Holstein Conformation & Pro$, April 2026), SWEETVIEW GRINCH P (+17 Conf), HAS IT ALL (+15 Conf), and PAZZLE (+16 Conf) remain prime options.
  • If your herd wants show‑type without walking away from income, focus your main matings on bulls that pair high Conf with Pro$ north of +1900 — again, PAZZLE and HAS IT ALL are prime examples — and reserve lower‑Pro$ extreme type sires for donors and best cow families.

Avoid treating ROZLINE as a top‑end Pro$ sire after his drop to +2038 (Canada Holstein Pro$, April 2026); he now fits best as a type and components tool.

Inbreeding-Sensitive ET Programs and Outcross Management

If your ET work already stacks Renegade/Parfect, BEYOND, SHEEPSTER, and Rosemary‑line bulls, the April 2026 lists are a reminder that the top of Canada Holstein LPI, Pro$, GPA LPI, and GPA Pro$ is heavily concentrated around a few families.

  • If your herd prioritizes inbreeding control, deliberately work bulls like DROUNER KL AUGUSTUS P RED (+3786 LPI, +2145 Pro$, Canada Holstein LPI & Pro$, April 2026) and KOEPON OH ROBIN RED (+3576 LPI, +2302 Pro$, Canada Holstein LPI & Pro$, April 2026) into donor matings as Red, alternative‑family outcrosses.
  • If your ET program leans heavily on a handful of genomic GPA LPI or GPA Pro$ bulls sharing similar sires and grandsires, spread risk by adding slightly lower‑ranked genomic sires with less pedigree overlap, even if their GPA LPI or GPA Pro$ is 50–100 points lower.

Within 30 days, run a quick pedigree audit on your donors against your top five service sires; any donor‑sire combination that repeats the same 2–3 sires or grandsires on both sides should have at least one Red or alternative‑family option added to the mating plan.

Genomic-Heavy Portfolios (Studs and Large Herds)

If your program leans heavily on genomic bulls, the April 2026 Canada Holstein GPA LPI and GPA Pro$ lists highlight both opportunity and churn.

  • If your herd prioritizes fast gain with controlled risk, you can use bulls like SIEMERS SSI ROSMRY TONKS‑ET (+4179, Canada Holstein GPA LPI, April 2026) or WELCOME GUSTAVSSON‑ET (+4064, Canada Holstein GPA LPI, April 2026) as sire‑of‑sons and key donor mates, but you should spread that exposure over multiple genomic bulls rather than anchoring on one.
  • If your herd wants more stability, aim to keep at least 40–50% of matings on high‑reliability daughter‑proven anchors like PARFECT, PATTERN, CABO, REMOVER PP, and ALTAINSCAPE, and use genomic sires as the “top‑up” rather than the core.

A practical threshold: if more than 60–70% of your planned matings for the next proof interval are to bulls from the top 10 of the April 2026 GPA LPI or GPA Pro$ lists, you’re probably carrying more genomic volatility than necessary for the same level of genetic gain.

Key Takeaways:

  • ROZLINE’s profile has flipped: he’s still +16 Conf and +3810 Canada LPI (April 2026) but lost 626 Canada Pro$ vs December 2025, so he’s now a type specialist, not a Pro$ anchor.
  • PARFECT (+3914 Canada LPI, April 2026) and PATTERN (+2974 Canada Pro$, April 2026) are the key proven anchors, but both sit in a compressed top band where 40–60 LPI or 200–250 Pro$ moves can reshuffle ranks without changing cow‑side reality.
  • GRAZIANO (−444 Canada Pro$) and several other December 2025 headliners took meaningful Pro$ trims, while POWERSTAR arrives at +2854 Canada Pro$ (April 2026), so any sire lineup built on last run’s income numbers needs a fresh audit.
  • Genomic GPA LPI and GPA Pro$ tops are still churning, so herds with >60–70% of matings on a handful of young sires are running higher portfolio risk than the Canada Holstein daughter‑proven lists alone would suggest.
  • For herds prioritizing income, robots, show type, or inbreeding control, this run clearly separates which bulls stay as everyday service sires (PATTERN, CABO, PARFECT, POWERSTAR) and which move to niche roles or outcross use (ROZLINE, PAZZLE, HAS IT ALL, AUGUSTUS P RED, ROBIN RED).

Switzerland April 2026 ISET: Torchlight at +1519 Tops a Recalibrated, High‑Churn Genomic Top 10 with 4 New Bulls

Tuesday, April 7th, 2026

Boston dropped 118 ISET points and still cracks the top 10. That tells you everything about what Switzerland’s recalibrated index is—and isn’t—rewarding.

Executive Summary: Switzerland’s ISET was recalibrated for April 2026—with the standard deviation reset to 100, heavier component weighting, and mastitis resistance replacing SCC—it reshuffled the entire genomic top 10. Progenesis Torchlight (Sheepster x Gameday) takes over at +1519 ISET, pushing former #1 Monset to 4th after a 101-point drop; four new bulls entered the top 10, four fell out, and the #1-to-#10 spread compressed to just 47 points. The biggest rank mover is DG Caarma, jumping from 23rd to 6th on raw production (+2,212 kg milk, IPL 153)—but his udder’s at 103 and fertility at 98, so he’s not a free lunch. On the proven side, Peak Powerhouse surged to #1 Interbull at +1520 ISET with 82% reliability, while domestic anchors Topstory (+1420, 91% rel) and Ranger (+1398, 99% rel) sit 100+ points below the genomic leaders with far less re-ranking risk. Five of the top 15 genomic bulls carry Gameday as MGS—if your herd‘s already deep in that line, Lars-Acres Caruthers-S (#3, +1505, Ice Cube-S x Van Gogh) is probably your most valuable outcross play right now. Any matings still queued to Beautyman, Logic, or Fireking based on December rankings need a hard second look; all three dropped out of the top 15 under the new weights.

April 2026 Swiss ISET

The April 2026 Swiss proof run isn’t just a routine update—it’s a structural reset. The ISET has been recalibrated (standard deviation reset to 100), with greater emphasis on fat and protein production, and mastitis resistance now replaces somatic cell count in the index. Every published April 2026 ISET value has dropped relative to December 2025, many by 60–120 points, but the rankings—not the raw numbers—tell the real story. An April 2026 ISET above 1500 now signals a truly elite bull; old 1600+ levels are no longer the expectation under the new scale.

Progenesis Torchlight (Sheepster x Gameday) emerges as Switzerland’s new genomic ISET leader at +1519 in the April 2026 run, leapfrogging from 5th at +1584 in the December 2025 Swiss ISET genomic evaluation. TGD-Holstein Monset, December’s dominant #1 at +1603, slides to 4th at +1502 in April 2026—a relative repositioning that reflects how the new production-weighted formula punishes moderate-milk, high-functional profiles when components don’t fully compensate. For AI companies, the shift in power toward more extreme production profiles at the very top of a traditionally Swiss-domestic-friendly system is significant. For breeders, this recalibration demands fresh thinking on sire stacking and what “balance” now costs in ISET points.

On the daughter-proven Interbull side, Peak Powerhouse moves into the #1 Interbull daughter-proven position in the April 2026 Swiss ISET evaluation at +1520 ISET, driven by extreme production (2,530 kg milk, +135 kg fat, +113 kg protein) that aligns closely with the new weighting of fat and protein. OCD Trooper Sheepster, December 2025’s Interbull #1 at +1537, comes in at +1467 and the second spot in April 2026.

What Changed at the Top?

Genomic ISET Top 10 Reshuffle (December 2025 vs April 2026)

The April 2026 Swiss genomic ISET top 10 retains 6 bulls from the December 2025 Swiss genomic ISET top 10 and adds 4 new entrants. Here is the structural picture with both runs and explicit movement:

9Les Verdaux EGANHadley x Gordon1474 ———New entrant
10Eichhof DOVERTroy x Topstory1472 1531 18−59Major climber

In the April 2026 Swiss genomic ISET run, the spread between #1 Torchlight (+1519) and #10 Dover (+1472) is 47 ISET points. In the December 2025 Swiss genomic ISET run, the same band between #1 Monset (+1603) and #10 B.O.A. Fireking (+1549) was 54 points. The recalibration has squeezed the elite into a narrower absolute band, so every 5–10 point gap at the top is now more meaningful.

Top-10 Trait Averages: December 2025 vs April 2026

Using the published Swiss genomic ISET lists, the structural shift shows up not just in ranks but in trait averages:

Metric (Genomic Top 10)Dec 2025 (approx.)Apr 2026 (approx.)
Average milk (kg)≈ +1,560 kg (Monset 1,217; Boston 1,275; Timeout 1,527; Torchlight 2,106; Hadley 1,942; Logic 1,408; Race 1,812; Lebron 1,589; Fireking 1,562; Keylan 1,616) ≈ +1,660 kg (Torchlight 1,954; Hadley 1,891; Caruthers-S 2,180; Monset 1,217; Race 1,808; Caarma 2,212; Timeout 1,443; Boston 1,290; Egan 1,956; Dover 1,420)
Fat kg patternAlready high (most bulls +85–140 kg fat) Consistently high; most bulls >+100 kg fat (Torchlight 130; Hadley 130; Race 111; Caarma 131; Dover 107)
ITP patternStrong type bulls like Monset (130), Boston (116), Beautyman (143) Still strong, slightly more clustered: Egan 133; Monset and Dover 130; Torchlight 120; Hadley 121

The pattern is clear: average milk and fat kilos in the top 10 have nudged upward, while type remains strong but no longer defines the very top by itself.

Drop-Outs From the December 2025 Genomic Top 10

Four bulls fall out of the Swiss genomic ISET top 10 when we move from December 2025 to April 2026:

  • TGD-Holstein BEAUTYMAN (Globed x Astral): December 2025 Swiss genomic ISET #3 at +1586; in April 2026, he is at +1427 ISET and well outside the top 20. His April production—+1,141 kg milk, −0.02% fat, +0.17% protein—and functional strengths (ITP 143, IFF 130) are no longer enough in a more production-heavy index.
  • Vatland Hendel LOGIC (Bite x Taos): December #7 at +1563; April 2026 rank 17 at +1451. He offers +1,487 kg of milk, +100 kg of fat, and +75 kg of protein, but a relatively weaker type (Udder 96, Format 94) is now more exposed, as component leaders are crowding the top.
  • swissgen LEBRON (Alvin x Star): December #9 at +1551; April rank 16 at +1453. He remains a strong bull with fertility 122, calving maternal 126, and ITP 125, but sits just outside the April 2026 Swiss ISET top 10 under the recalibrated system.
  • B.O.A. FIREKING (Solo x Improbable): December #10 at +1549; April 2026 around rank 25 at +1432. His April figures—+1,489 kg milk, +0.12% fat, +0.16% protein, ITP 131, fertility 113—still define a robust sire, but the new ISET weighting prefers even stronger production.

The Big Movers: Up, Down, and Out

Major Climbers

DG CAARMA (Percival x Altazazzle, NL) is the biggest structural climber in the April 2026 Swiss genomic ISET top group. He moves from 23rd at +1515 in the December 2025 Swiss genomic ISET evaluation to 6th at +1482 in the April 2026 run. His April proof shows +2,212 kg of milk, +131 kg of fat, +94 kg of protein, and an IPL of 153—the highest in the current top 10. The price is a narrower functional profile: Udder 103, fertility 98, and moderate feet/legs (118).

Eichhof DOVER (Troy x Topstory, CH) climbs from 18th at +1531 in December 2025 to 10th at +1472 in April 2026. Dover brings +1,420 kg milk, +107 kg fat with +0.53% fat, +75 kg protein with +0.30% protein, ITP 130, Udder 118, Format 120, and longevity 116. He’s a classic balanced platform sire: strong type, good production, and sensible fitness.

Lars-Acres CARUTHERS-S (Ice Cube-S x Van Gogh, CH) is a completely new face at #3 with +1505 ISET in the April 2026 Swiss genomic ISET run. He offers the highest milk in the top 10 (+2,180 kg), with +101 kg fat, +82 kg protein, fertility 123, and persistency 120. Component percentages are modest (+0.12% fat, +0.10% protein), but his volume and fertility make him a high-output, high-fertility outcross relative to the usual Gameday/Ranger/Troy lines.

Les Verdaux EGAN (Hadley x Gordon, CH) debuts at #9 with +1474 in April 2026. He has the highest ITP in the genomic top 15 at 133, with Format 125, Feet/Legs 123, and Udder 122. Egan is the go-to option for herds that want to stay in the ISET top band without compromising top-tier type.

Major Fallers

TGD-Holstein MONSET (Hadley x Gameday, CH) drops from #1 at +1603 in the December 2025 Swiss genomic ISET run to #4 at +1502 in April 2026 (−101 points). His April profile remains strong: +1,217 kg milk, +96 kg fat, +66 kg protein, ITP 130, Udder 129, longevity 125, fertility 119. He hasn’t failed; he’s been outpaced by bulls whose production profiles fit the recalibrated ISET slightly better.

Sous-Moron BOSTON (Casting x Gameday, CH) falls from #2 at +1593 in December 2025 to #8 at +1475 in April 2026 (−118 points, the largest drop among the December top 10). His April profile—+1,290 kg milk, +83 kg fat, +64 kg protein, longevity 130, fertility 125, calving maternal 122—marks him as one of the best health/fertility sires in the top group, but his more moderate production now costs top-end ISET points.

Progenesis TIMEOUT (Peregrine x Dzunda, CA) moves from #4 at +1584 in December 2025 to #7 at +1476 in April 2026 (−108 points). Timeout maintains exceptional fat percentage (+0.87%) and strong components (+139 kg fat, +73 kg protein), but with +1,443 kg milk, he is outgunned by the very top volume sires. He’s now more of a targeted components bull than an all-around index leader.

Notable Drop-Outs

TGD-Holstein BEAUTYMAN is the clearest example of a bull whose Swiss ISET leadership was heavily dependent on the pre-2026 weighting. His ISET drops from +1586 in the December 2025 Swiss genomic ISET run (rank #3) to +1427 in April 2026, and he falls out of the top 20. His April production profile—+1,141 kg milk, −0.02% fat, +0.17% protein—combined with top-end type (ITP 143) and strong fitness (IFF 130) is no longer prioritized by the recalibrated, production-heavier ISET. He still has a role as a functional/type sire, but not as a front-line index driver.

What the ISET Is Rewarding This Run

The recalibrated April 2026 Swiss ISET clearly rewards high milk volume plus strong components, with functional traits still important but less able to carry a bull into the very top on their own.

The Dominant Trait Package in April 2026

Across the April 2026 Swiss genomic ISET top 10:

  • Average milk ≈ +1,660 kg, up from ≈ +1,560 kg in December 2025, with Caruthers-S (+2,180 kg) and DG Caarma (+2,212 kg) defining the high end.
  • Fat kilos are consistently high: Torchlight +130 kg, Hadley +130 kg, Race +111 kg, DG Caarma +131 kg, Dover +107 kg.
  • Component percentages remain positive to strongly positive; several bulls combine high volume with +0.30% or more fat.

ITP values in the April 2026 genomic top 10 cluster between 110–133, with Egan (133), Monset and Dover (130), Torchlight (120), and Hadley (121) at the high end. Longevity averages above 120 in the top 10, led by Race (136), Boston (130), and Hokovit Galileo 6 (129), and fertility averages around 109, with standouts like Caruthers-S (123) and Monset (119).

Trait Trade-Off Clusters

This run reveals three actionable clusters:

  • Production rockets: Torchlight, DG Caarma, Caruthers-S. These bulls sit at the very top of the Swiss ISET ranking, primarily due to their production horsepower and strong IPL. Trade-off: they often show weaker points in fertility or udder (e.g., Caarma Udder 103, fertility 98; Torchlight fertility 100, temperament 92).
  • Balanced platforms: Monset, Dover, Egan. These bulls combine strong but not extreme production with high type and solid fitness. They sit 15–40 ISET points below the #1 bull, but offer lower multi-trait risk.
  • Functional specialists: Boston, Race, and bench bulls like Swissgen Pompon. These bulls preserve very high longevity and fertility and often offer excellent calving traits, but give up some ISET relative to the production rockets.

For elite breeders, the April 2026 ISET selection is about deciding where on that triangle—production, balance, robustness—they want their sire portfolios to sit.

Stud Power, Family Power, and Outcross Space

Stud and Country Representation

In the April 2026 Swiss genomic ISET top 15, Swiss domestic breeding entities (TGD-Holstein, swissgen, Hokovit, Eichhof, Sous-Moron, Rhein-Valley, Les Verdaux) account for 7 bulls. Progenesis holds two top-10 genomic slots (Torchlight #1, Timeout #7), and Cookiecutter contributes Hadley (#2) and Hoedown (#11) into the Swiss top genomic list. DG Caarma adds a strong Dutch presence, and Race represents a German sire evaluated within the Swiss ISET system.

Bloodline Concentration

The April 2026 Swiss genomic ISET top 15 shows clear bloodline concentration:

  • GAMEDAY as maternal grandsire for five of the top 15 bulls: Torchlight, Hadley, Monset, Hoedown, and K-Star-Fs Alcatraz.
  • HADLEY as sire of Monset and Egan, while also ranking #2 himself in the April 2026 genomic list.
  • TROY as sire of Dover and Hokovit Galileo 6.

This concentration implies that herds already heavy in Gameday, Hadley, or Troy on the female side risk accelerating inbreeding if they load their matings with the current Swiss genomic ISET top bulls without a diversification plan.

Outcross Opportunities

Given that concentration, high-value outcross bulls within the April 2026 Swiss genomic ISET list are:

  • Lars-Acres CARUTHERS-S (Ice Cube-S x Van Gogh): No Gameday, Ranger, or Troy in his immediate pedigree. He offers elite milk (+2,180 kg), strong fertility (123), and high persistency (120), making him the premier production + fertility outcross bull in the current top 3.
  • Race (Ranking x Rover): A German-based sire with Ranking and Rover, offering longevity 136, calving direct 118, and calving maternal 119. He’s particularly attractive for inbreeding-sensitive herds that also want to reinforce survival and calving ease.
  • Progenesis TIMEOUT (Peregrine x Dzunda): Avoids the main dominant sires and provides extreme fat percentage (+0.87%) with +139 kg fat. He is a targeted tool for herds where a higher fat test is a major revenue driver and bloodline diversification is a priority.

Volatility, Reliability, and Proof-Run Risk Profile

Genomic Reliability Landscape

The April 2026 Swiss genomic ISET top group operates within a narrow reliability band of roughly 71–75%. This means:

  • Every bull in the top 15 sits in the genomic prediction reliability zone, not high-reliability proven territory.
  • The observed churn—4 new bulls in the top 10 and 4 drop-outs between December 2025 and April 2026—is exactly what you’d expect at this reliability level.

Bulls like Torchlight (72% reliability), Caruthers-S (71%), and Egan (72%) may move substantially as daughter groups expand. This is why the article positions them as high-impact, high-volatility plays rather than permanent fixtures.

Domestic Daughter-Proven Stability

The domestic Swiss daughter-proven ISET list offers a stability counterweight:

  • Topstory (Altazazzle) leads the April 2026 domestic daughter-proven Swiss ISET at +1420 with 91% reliability, +2,360 kg milk, and ITP 124.
  • Ranger (Rubels) sits at +1398 with 99% reliability, +1,429 kg milk, +0.42% fat, and ITP 125.

For proof-based programs, these bulls establish a “stability band” about 120–130 ISET points below the genomic leaders, but with reliability in the 90–99% range. For many herds, that gap is an acceptable price for risk reduction.

Interbull Daughter-Proven Re-Ranking

On the Interbull Swiss ISET list:

  • Peak Powerhouse rises to +1520 ISET in April 2026, with 82% reliability, +2,530 kg of milk, +135 kg of fat, and +113 kg of protein.
  • OCD Trooper Sheepster moves from +1537 in December 2025 to +1467 in April 2026, now #2.
  • Progenesis Pattern at +1451 and Progenesis Wesson at +1445 continue to anchor sire-of-sons roles backing bulls like Hadley.

Even in the daughter-proven Interbull set, the April 2026 recalibration reshuffles rankings, though far less dramatically than in the genomic lists.

Strategic Sire Roles and Mating Concepts for Elites

1. Index Leaders for Aggressive Genomic Programs

Use these bulls if your herd prioritizes maximum genetic gain and can tolerate genomic volatility in a 2–3 year semen pipeline.

  • Progenesis TORCHLIGHT (+1519, 72% rel, April 2026 Swiss genomic ISET): High-production leader with +1,954 kg milk, +130 kg fat, +88 kg protein, IPL 151, ITP 120. If your herd is targeting rapid index gains and already has solid fertility, Torchlight is a top pick; be cautious in situations where temperament is critical (robot herds, parlors with nervous cows), as his temperament index is 92.
  • Cookiecutter HADLEY (+1513, 73% rel, April 2026 Swiss genomic ISET): Balanced high-index sire with +1,891 kg milk, +130 kg fat, +84 kg protein, ITP 121, and good calving maternal (110). If you’re building sire stacks for genomic programs (sons, bull dams), Hadley is a core building block, particularly on outcross cow families.
  • DG CAARMA (+1482, 72% rel, April 2026 Swiss genomic ISET): If you need maximum production in high-input housed systems, Caarma’s +2,212 kg milk, +131 kg fat, +94 kg protein, and IPL 153 are unmatched in the current top 10. Only use him where you can pair him with cows carrying strong udder and fertility genetics, as his udder (103) and fertility (98) are weak points.

2. High-Reliability Anchors

Use these bulls to stabilize your herd or proof program if your genomic lineup already carries significant risk.

  • Topstory (+1420, 91% rel, April 2026 domestic Swiss ISET): If your herd wants a reliable ceiling with strong production and type, Topstory is a prime choice—+2,360 kg milk, good solids, and ITP 124. He is particularly useful on donor cows where embryos will be marketed into more conservative, proven-biased markets.
  • Ranger (+1398, 99% rel, April 2026 domestic Swiss ISET): If your conception rate or herd economics can’t tolerate volatility, Ranger is the “do-no-harm” reliability anchor—high milk, strong fat %, and proven type and fitness. He suits both commercial and seedstock herds that want proven stability over cutting-edge rankings.
  • Peak POWERHOUSE (+1520, 82% rel, April 2026 Interbull Swiss ISET): If your herd can use foreign-proven sires, Powerhouse is a natural transition bull between genomic leaders and domestic proofs. He fits high-output, housed Holstein herds that already employ Interbull genetics and want a high-index but more reliable anchor.

3. Health/Fertility Specialists and Corrective Sires

Use these bulls if your main herd problem is fertility, longevity, or calving, and you can accept a small ISET discount.

  • Sous-Moron BOSTON (+1475, 72% rel, April 2026 Swiss genomic ISET): If your herd’s reproduction KPIs are weak, Boston’s longevity 130, fertility 125, and calving maternal 122 offer a powerful corrective profile while still keeping you in the top-10 ISET band. He’s ideal to stabilize high-output but fragile cow families.
  • Race (+1489, 71% rel, April 2026 Swiss genomic ISET): If cow survival and calving ease are your primary constraints, Race’s longevity 136, calving direct 118, and calving maternal 119 make him the go-to bull. He’s well-suited to heifers and to herds that have seen too many difficult calvings from extreme-production sires.
  • Swissgen POMPON (+1390, 71% rel, April 2026 Swiss genomic ISET): If your herd has had mastitis or reproductive issues, Pompon’s fertility 130 and longevity 133 warrant a place as a bench bull even at a slightly lower ISET. He’s particularly valuable as a “health anchor” in multi-bull programs.

4. Type/Show-Leaning Sires With Index Discipline

Use these bulls if you run type- or show-focused herds but refuse to walk away from the index.

  • Les Verdaux EGAN (+1474, 72% rel, April 2026 Swiss genomic ISET): For type herds that still want multi-trait strength, Egan’s ITP 133, Format 125, Feet/Legs 123, and Udder 122 make him the most attractive type sire in the current genomic elite. He suits herds that already have an adequate frame and want to stamp udders and legs.
  • Eichhof DOVER (+1472, 72% rel, April 2026 Swiss genomic ISET): If your classification targets focus on udders and balanced frames, Dover’s ITP 130, Udder 118, and Format 120 make him one of the safest type-balanced sires in the top 10. Robot herds with heavy classification programs can particularly benefit from his combination of udder quality and acceptable milking speed.

5. Outcross Sires for Inbreeding Management

Use these bulls if your mating program shows heavy saturation with Gameday/Hadley/Troy.

  • Lars-Acres CARUTHERS-S (+1505, 71% rel, April 2026 Swiss genomic ISET): If more than roughly 30% of your current matings trace back to Gameday or Ranger within three generations, Caruthers-S should move to the top of your diversification list. He offers elite milk, strong fertility, and high persistency without stacking the dominant Swiss sire lines.
  • Progenesis TIMEOUT (+1476, 71% rel, April 2026 Swiss genomic ISET): If your fat test limits milk price and you need to drive percentages without doubling down on Gameday, Timeout’s +0.87% fat and +0.27% protein make him a targeted outcross specialist. Use him on cows with solid milk volume but less extreme components.
  • Beyond HI-POWER (+1469, 74% rel, April 2026 Swiss genomic ISET): If you need a non-Gameday, non-Ranger bull that still offers high index plus good longevity (125) and calving maternal (125), Beyond Hi-Power is a logical option.

6. Herd-Type Calibration

  • High-input, housed herds: If your herd runs TMR, high stocking density, and high output per stall, bulls like Torchlight, Hadley, DG Caarma, and Caruthers-S should dominate the genomic segment, anchored by Ranger and Peak Powerhouse on the proven side. You gain maximum production; you give up some reliability and, for certain bulls, some fertility or udder.
  • Grazing or low-input systems: If cows must walk, maintain condition on grass, and conception is critical, emphasize Boston, Race, and Pompon, and lean harder on proven Topstory and Ranger. You gain robustness and survival; you give up some index speed and peak milk.
  • Robot herds: If milking speed and udder quality drive your economics, prioritize Dover, Egan, and Monset, and use Torchlight and DG Caarma more selectively where robot hardware and cow temperament can support them. You gain structural reliability in the parlor; you give up some upside in raw production.

7. 30-Day Action Plan

Within the next 30 days:

  1. Audit your bloodlines. Pull your current mating list and mark all matings where the dam traces to Gameday, Hadley, Troy, or Ranger within three generations. If more than ~30% of your matings fall into that category, prioritize Caruthers-S, Race, or Timeout for the next round of matings to widen your sire base.
  2. Re-evaluate December favorites. Specifically review any planned matings using Beautyman, Logic, Lebron, or Fireking based primarily on their December 2025 Swiss genomic ISET positions. Check whether their April 2026 ISET and trait profiles still fit your index thresholds and herd goals; if not, redirect those matings toward Monset, Dover, Boston, or Egan, depending on whether you prioritize type, balance, or health/fertility.

Key Takeaways:

  • The April 2026 Swiss ISET recalibration (SD reset to 100, more weight on fat/protein, mastitis replacing SCC) compressed the genomic top 10 into a 47‑point band and pushed average milk and fat kilos higher.
  • Progenesis Torchlight is the new Swiss genomic ISET #1 at +1519 (April 2026), with four new bulls entering and four dropping out of the top 10, signaling a genuinely high‑churn, medium‑reliability (≈71–75%) leaderboard.
  • DG Caarma and Caruthers-S define the new production ceiling (> 2,200 kg milk, 130 kg fat), while Monset, Dover, and Egan become the key “balanced platform” sires, trading 15–40 ISET points for stronger type and fitness.
  • Proven anchors Topstory (+1420, 91% rel), Ranger (+1398, 99% rel), and Interbull leader Peak Powerhouse (+1520, 82% rel) set the stability band roughly 100 ISET points below the genomic leaders—critical for herds that can’t afford big re‑ranking swings.
  • With Gameday showing up as MGS in 5 of the top 15 genomic bulls, portfolios already heavy in that line should lean hard on Caruthers-S, Race, Timeout, and Pompon to manage inbreeding while still staying in the Swiss ISET money zone.

April 2026 Scandinavia NTM: Fugleman +3 to Proven #2, Jefe Enters Genomic Top 5, VikingGenetics at 21/30 Bulls

Tuesday, April 7th, 2026

RAINOW’s still #1 proven, but his lead over #2 shrank from 7 points to 2 in one run. Fugleman’s closing fast.

Executive Summary: Fugleman just gained +3 to NTM 38 in the April 2026 Scandinavia proven run, tightening the gap to PEAK RAINOW-ET at NTM 40 and reshaping the top of the daughter-proven list. On the genomic side, VH Sheriff slipped slightly to NTM 50 while a new GenoSource bull, Jefe, arrived out of nowhere at NTM 45 to take genomic #4 in his first NAV appearance. VikingGenetics now holds 21 of the top 30 genomic NTM slots, so if most of your semen tank starts with “VH,” you’re stacking a lot of the same gene pool whether you mean to or not. The data behind the lists show that the top 5 in the genomic lists, while the proven top 6 barely moved, which is a not-so-subtle reminder of where the real risk lies. For robot herds, Fugleman (milkability 126) and ROVER PK (127) now look like the safest proven anchors, while Sheriff’s milkability 82 is a hard red flag unless your parlor can handle slow milkers. If you’re chasing health and longevity, ROVER PK and VH StoryRC give you fertility and general health in the teens and 120+ longevity without chasing the very top NTM point or two. The smart move in the next 30 days is to audit your sire list for VH overuse, slide in at least one non-VH genomic sire like DG Brujito, Jefe, or AltaMULLER, and decide how much of your next order you really want riding on high-flyer genomics vs the now very-solid proven top tier.

April 2026 Scandinavia NTM

Fugleman posted the largest NTM gain among Scandinavia’s daughter-proven elite — up +3 to April 2026 NTM 38, vaulting from #4 to #2 and closing to within 2 points of PEAK RAINOW-ET. On the genomic side, a 2024-born GenoSource bull called Jefe appeared on the NAV list for the first time at April 2026 NTM 45, slotting into #4 — the highest debut in this run, transmitted via the April 7 Interbull GMACE delivery. VH Sheriff still leads at genomic NTM 50, but he shed a point from December, and every bull in the genomic top 5 moved down.

The proven top 10 tells a different story from the genomic top 30. The proven list is gaining stability: 8 of 10 bulls held their positions, and the new entrants (Simba P, Rosario) arrived on expanding daughter data. The genomic list, meanwhile, saw universal NTM erosion across its top tier — the normal regression pattern, but broad enough to warrant recalibrating confidence in any single genomic number. For breeders building sire portfolios, the gap between genomic ceiling and proven floor keeps narrowing.

What Changed at the Top?

Genomic NTM: April 2026 vs December 2025

Seven of ten bulls held top-10 status. Three new entrants displaced three exits. The index spread tightened slightly: 9 points (#1 to #10) in April vs 10 points in December.

Proven NTM: April 2026 vs December 2025

Eight bulls held their spots. The two new entrants — Simba P and Rosario — both carry accumulating daughter data. The index band compressed: 9 points (#1 to #10) in April vs 11 points in December, driven primarily by RAINOW dropping and Fugleman climbing.

The Big Movers: Up, Down, and Out

Risers

Fugleman — Proven: Dec NTM 35 #4 → Apr NTM 38 #2. The +3 NTM gain is the largest among all proven bulls in this run. Yield rose from 130 to 132, udder health jumped from 95 to 100 (+5), claw health from 94 to 96, and udder conformation from 114 to 116. Milkability dipped marginally from 127 to 126 (−1), and temperament (115) held. His genomic promise is being validated, not eroded, by daughter performance.

Jefe — Genomic: not in December NAV evaluation → Apr NTM 45 #4. A 2024-born GenoSource bull (distributed through STgenetics®) entering at the highest NTM of any first-evaluation animal this run. His profile is all growth (124) and frame (118), with general health 111, claw health 109, and udder 115 providing functional backup. The catch: fertility (98) and birth (97) sit below the Nordic baseline. First-run genomic bulls in the NAV system routinely shift 3–5 NTM within two runs — treat this as a high-upside, high-variance entry.

ROVER PK — Proven: Dec NTM 32 #8 → Apr NTM 34 #6. Gained on fertility (115→117), temperament (117→121), and udder health (90→92), all on expanding daughter data. General health 121, milkability 127, and calving 110 make him the clearest functional specialist in the proven top 10.

VH ShaneRC — Genomic: Dec NTM 41 #13 → Apr NTM 42 #8. One of only three genomic bulls that gained NTM this run. A red carrier with general health 117, fertility 108, and udder health 107 — the most functionally balanced bull among the genomic top-10 entrants.

VH Clapton — Proven: Dec NTM 25 #29 → Apr NTM 28 #17. Gained +3 NTM and 12 ranks. Yield jumped from 121 to 125 (+4), and his saved feed, 118; general health, 110; and longevity, 116, position him as a quietly accumulating functional sire worth monitoring.

AltaMULLER — Genomic: Dec NTM 40 #17 → Apr NTM 41 #9. The only Alta Genetics representative in the genomic top 30 gained +1 NTM and 8 ranks. Growth 122, calving 109, and claw health 114 give him a clear functional package from outside VikingGenetics’ pipeline.

Decliners

PEAK RAINOW-ET — Proven: Dec NTM 42 #1 → Apr NTM 40 #1. Still #1, but the margin over #2 narrowed from 7 points to 2. Yield declined from 130 to 127 (−3) and growth from 110 to 108. Udder health improved from 97 to 100, claw health from 113 to 115, and longevity from 103 to 105. RAINOW’s management traits are holding or improving as daughters accumulate — but his production advantage is eroding. Another 2-point drop next run puts Fugleman or VH SKILLS within striking distance of #1.

VH STINGER — Proven: Dec NTM 30 #14 → Apr NTM 26 #24. A −4 NTM decline driven by yield dropping from 117 to 113 and temperament from 98 to 94. This pushes STINGER to the margin of the proven top 25. Milkability (118) and fertility (112) retain some niche value, but their trajectories are downward.

August — Proven: Dec NTM 27 #17 → Apr NTM 22 #50. The run’s largest proven-list decline: −5 NTM and −33 ranks. Fertility fell from 119 to 115 and udder health from 103 to 98 — classic daughter-proof regression. Longevity (126) remains high, but a 5-point NTM drop in a single run pushes him to the margins pending further data.

VH Galaxy — Genomic: Dec NTM 44 #4 → Apr NTM 42 #7. Down 2 NTM and 3 ranks. General health (120) and longevity (122) remain among the best in the top 10, but yield and NTM are both trending in the wrong direction for a second evaluation.

VH Mads P — Genomic: Dec NTM 48 #2 → Apr NTM 46 #3. Lost 2 NTM and slipped behind DG Brujito. His trait profile is still deep — fertility 121, claw health 117, milkability 116 — but the polled carrier that was once a clear #2 is now in a tighter race with Brujito and Jefe.

Notable Drop-Outs

Five bulls dropped from the December genomic top 20, and all five lost exactly 2 NTM: VH SloppyP (#14→#29), VH Smasher (#15→#30), Cascari (#18→#32), VH Caspian (#19→#39), and VH KingRC (#20→#40). The uniform −2 pattern is striking. NAV applied no base change between December 2025 and April 2026, so this is genuine genomic regression rather than a rescaling artifact. None have collapsed — they’re still in the top 40 — but in a compressed NTM band, even 2 points costs 10–20 rank positions.

On the proven side, VH Comply (Dec NTM 27 #18) disappeared entirely from the April top-50 published list. Lambeau (Dec #19 → Apr #21) and MAXIMUS (Dec #20 → Apr #27, NTM 26→25) also dropped out of the top 20, though both remain on the list.

What the NTM Is Rewarding This Run

Aggregate trait averages for the top 10 reveal subtle but meaningful shifts from December:

TraitGenomic Top 10 AprGenomic Top 10 DecΔProven Top 10 AprProven Top 10 DecΔ
Yield132.4133.6−1.2126.5127.0−0.5

General Health109.2107.8+1.4106.1104.6+1.5
Claw Health106.3107.4−1.1105.0102.2+2.8

The top 10 genomic traits dipped in yield and fertility while improving in general health — partly driven by Jefe’s general health 111 replacing Fortuny’s 96. The proven top 10 tells the more interesting story: general health climbed +1.5, and claw health surged +2.8, driven by Simba P’s claw health 113 and Rosario’s general health 126 entering the top 10 while VH SWISH (general health 101) and VH CRONOS (claw health 103) dropped out.

Stud Power, Family Power, and Outcross Space

Who Owns the Genomic Top?

VikingGenetics (VH prefix) controls 21 of the 30 published genomic NTM slots in April 2026, up from 20 of 28 in December. The dominance is concentrated in Danish-registered bulls — 14 of the top 30 carry DNK registration codes — with Finnish-born (VH ShaneRC, VH Timer, VH Lullaby, VH SloppyP) and Swedish-born (VH SANDRO) VH bulls providing geographic diversity within the program.

Origin/CompanyGenomic Top 30 (Apr)Notes
VikingGenetics (VH)21DNK 14, FIN 4, SWE 1, DEU 1, FRA 1

GenoSource / STgenetics®1Jefe (highest non-VH NTM at 45)
Other US-bred1Prizepick
Dutch-bred (DG/other)2DG Brujito, Bravo
Alta Genetics1AltaMULLER

On the proven side, VH representation in the top 10 fell from 3 bulls (VH SKILLS, VH SWISH, VH CRONOS) in December to 1 (VH SKILLS) in April. The proven top 10 is dominated by internationally-bred bulls: 4 US-registered (RAINOW, Fugleman, ROVER PK, Engineer), 3 German-registered (SKILLS, SUPPORTER, Simba P), 1 Dutch (CAMDEN), 1 French (Rosario), and METRO (German).

Outcross Candidates

Without explicit sire/grandsire columns in the NAV lists, direct pedigree mapping isn’t possible. Registration-code diversity identifies clear outcross options relative to the VH-dominated pipeline:

  • Jefe (USA, NTM 45): GenoSource-bred, distributed through STgenetics® — the highest-NTM bull from outside VikingGenetics’ breeding program.
  • DG Brujito (NLD, NTM 46): Diamond Genetics breeding, Dutch pedigree base — likely the most pedigree-distant option in the genomic top 5.
  • AltaMULLER (USA, NTM 41): Alta pipeline genetics, growth 122, and claw health 114.
  • Saturn RDC (DEU, NTM 39): German red-carrier with the deepest health breadth among non-VH genomic bulls — general health 108, claw health 121, udder 115, calving 113.

Polled and Red-Carrier Frequency

In the genomic top 20: 4 polled carriers (VH Mads P, Fly P, VH FlyerPP, VH KiloPRC) and 5 red carriers (VH ShaneRC, VH KenzoRC, VH StoryRC, VH KiloPRC, Saturn RDC). VH KiloPRC carries both. On the proven side, Simba P at #8 is the highest-ranking polled proven bull.

How Volatile Are Scandinavia’s NTM Rankings Right Now?

Genomic: Broad erosion, moderate churn

The genomic top 10 retained 7 of 10 bulls — moderate churn by NAV standards. The direction matters more than the count: every returning bull in the top 5 lost NTM (VH Sheriff −1, VH Mads P −2, DG Brujito −1, VH Galaxy −2, VH Darwin −1), and only 3 of 10 bulls gained even a single point. This universal downward pressure is expected to drive genomic regression as information accumulates, but it means the April numbers are likely still above where these bulls will stabilize.

April 7, 2026, was a NAV “small run” — genotypes were updated (including new Interbull GMACE transmissions), but phenotypic data were carried forward from the February 3, 2026, large run. The next full phenotype update comes with the May 5 large run.

The published genomic list includes only bulls without the DFS progeny test. With the top 30 dominated by 2024-born animals, daughter-proof confirmation is years away. Any sire portfolio built heavily on genomic NTM rankings needs to account for the possibility that individual bulls could re-rank by 3–5 NTM over the next two to three runs.

High-volatility flags: Jefe at NTM 45 on first evaluation carries the most re-ranking risk. VH Sheriff’s milkability of 82 introduces adoption risk independent of index movement — if milkability weighting or data shift, his NTM could be disproportionately affected.

Proven: Converging and stabilizing

The proven top 10 retained 8 of 10 bulls and added two new entrants with accumulating daughter data. Most proven NTM movements were ±1–2, with Fugleman’s +3 as the clear outlier. The exceptions signaling genuine corrections are VH STINGER (−4) and August (−5) — bulls whose December numbers overstated what daughters confirmed.

The proven top 6 (RAINOW, Fugleman, VH SKILLS, CAMDEN, SUPPORTER, ROVER PK) now represent the lowest-variance NTM tier available in the NAV Holstein system.

What This Means for Your Matings This Season

If your herd runs AMS/robotic milking

Milkability is non-negotiable, and this run sharply splits the elite. Among proven bulls, Fugleman (milkability 126, April NTM 38) and ROVER PK (milkability 127, April NTM 34) are the clear targets. Fugleman’s milkability is now confirmed by daughters, not predicted by a chip — that distinction matters for robot herds where throughput determines ROI. Be cautious with Simba P (milkability 94) and METRO (milkability 97) despite their NTM; these will cost you throughput.

On the genomic side, VH Sheriff’s milkability 82 is a significant risk for AMS operations — the lowest among all reported genomic top-30 bulls. If you want the highest genomic NTM accessible for robots, VH Mads P (NTM 46, milkability 116) is the safer call. VH Smasher (NTM 39, milkability 118) and VH StoryRC (NTM 41, milkability 114) carry above-average milkability with deep functional packages.

If your herd prioritizes production ceiling

VH Sheriff (genomic yield 136, NTM 50) and DG Brujito (genomic yield 136, NTM 46) lead the genomic list on raw yield. Among proven bulls, METRO (yield 132, NTM 31) and Fugleman (yield 132, NTM 38) top the production column. Jefe’s growth index of 124 is the highest in the genomic top 30 — if your program needs frame and growth from outside the VH gene pool, he fills that niche, but pair him only with cows whose fertility is already strong (≥110 herd-level), given his fertility of 98.

If your herd prioritizes health, fertility, and cow lifetime

VH StoryRC (genomic NTM 41) is the standout functional specialist: fertility 124, general health 112, claw health 113, longevity 120, feet & legs 121, and udder 115 form arguably the deepest functional package on the entire genomic list. The price: yield 117 is the lowest in the genomic top 20, and frame 86 means small-framed daughters. This is a bull for breeders who’ll trade production ceiling for a sustainable cow lifetime.

On the proven side, ROVER PK (NTM 34) combines fertility 117, general health 121, and claw health 114 on daughter data — the highest proven functional floor available. VH Racer (genomic NTM 39) sits just outside the top 20 but carries fertility 123, general health 121, claw health 114, and feet & legs 124. If you’re correcting a herd with below-average health or fertility, these three bulls belong in your mating rotation regardless of their NTM ranking.

If you need type and conformation improvement

SKATER (proven NTM 27) is the highest-ranking proven bull with a genuine type profile: frame 125, udder 118, claw health 112, feet & legs 110. His milkability (92) and temperament (86) are penalties — he’s not a blanket-use sire — but for targeted type correction on cows with adequate management traits, he has no functional equivalent among proven bulls.

VH Galaxy (genomic NTM 42) offers frame 117 paired with general health 120, longevity 122, and milkability 120 — the strongest combination of type plus function in the genomic top 10.

If you’re managing inbreeding against VH-dominated genetics

Do this within 30 days: Pull your sire lineup and cross-reference every active genomic bull against the VH registration prefixes (HOLDNKM, HOLFINM, HOLSWEM) for VikingGenetics’ Danish, Finnish, and Swedish units. With VH bulls holding 21 of 30 genomic slots, any Nordic herd using the NTM top list as its mating guide is almost certainly over-concentrated. If more than 60% of your genomic sires carry VH pedigrees, replace at least one with a non-VH alternative before your next mating round. DG Brujito (NTM 46) and AltaMULLER (NTM 41) give you NTM without adding to the VH concentration. On the proven side, CAMDEN (Dutch), Rosario (French), and Engineer (US) offer pedigree distance.

Bench Bulls to Watch

  • VH Racer (Genomic #24, Apr NTM 39): Fertility 123, general health 121, claw health 114, feet & legs 124, longevity 119. It may be the best functional package on the entire NAV list. Yield 117 caps his NTM, but if NTM weightings shift toward longevity or health, he climbs.
  • VH Timer (Genomic #14, Apr NTM 41): A 2025-born new entrant not on the December list. Fertility 119, longevity 115, frame 115, and temperament 116 give him the deepest all-around profile among 2025-born bulls in the top 15. His milkability 92 is a flag for robot herds, but the balance across functional traits is notable for a first-evaluation animal.
  • Saturn RDC (Genomic #20, Apr NTM 39): Growth 122, calving 113, general health 108, claw health 121, udder 115 from a German base — a genuine multi-purpose outcross.
  • VH SammyRC (Genomic #26, Apr NTM 39): Red carrier with udder health 120, claw health 116, longevity 121. Deep health, Scandinavian pedigree.
  • Rosario (Proven #10, Apr NTM 31): General health 126, feet & legs 125, udder 120 — the deepest health-and-type sire among proven bulls. Youngstock survival (81) is a hard flag, but for targeted mating plans on structural soundness, he’s unique.

Key Takeaways:

  • Fugleman’s April 2026 Scandinavia-proven NTM jumped from 35 to 38, pulling within 2 points of PEAK RAINOW-ET and confirming his management traits in daughters, not just genomics.
  • The genomic top is regressing: VH Sheriff slipped from NTM 51 to 50, every returning bull in the genomic top 5 lost ground, and Jefe’s first-run NTM 45 sits in the high‑variance zone.
  • VikingGenetics now owns 21 of the top 30 genomic NTM bulls, which means any herd using “top NTM” as its main filter risks stacking a very narrow VH gene pool unless it deliberately brings in outcross sires.
  • For robots and high‑throughput parlors, Fugleman (milkability 126) and ROVER PK (127) are now the safest proven anchors, while Sheriff’s milkability 82 makes him a genomic specialist for systems that can live with slower milkers.
  • The practical 30‑day job is to audit your sire list for VH saturation, plug in at least one non‑VH genomic bull (DG Brujito, Jefe, AltaMULLER, Saturn RDC), and decide how much of your next semen order you really want riding on high-flyer genomics vs the increasingly stable proven top tier.

Crisalis RF (+67) and Son Boero Lock In a 1-2 on Italy’s Proven gPFT – but Half the Top 10 Is New | April 2026

Tuesday, April 7th, 2026

Crisalis RF just added +67 gPFT and pulled his own son in behind him at #2 proven—while 5 fresh bulls quietly shoved veterans out of Italy’s top 10.

Executive Summary: Crisalis RF just tightened his grip on Italy’s April 2026 proven gPFT list, jumping +67 to gPFT 5247 while his son Boero debuts right behind him at #2. Half of the proven top 10 is new this run, and the proven top-10 average jumped +153 points, so anyone still mating off the December sheet is effectively working with a different lineup than ANAFIBJ’s current board. Ecbert and Rascasse still hold the domestic genomic 1–2, but that list has compressed into a 144‑point band, making “who’s #3 vs #8” more noise than signal. Vivify and Gladius blood is heavily represented and easy to over‑use on genomic and foreign lists, which is great for index but a real inbreeding trap if 30%+ of your recent matings already carry those lines. On the opportunity side, Boero, Glorydays, and Mantra give you proven‑tier options that actually out‑kicked their genomic calls, especially on components and IQC for cheese milk. The article walks through which bulls to anchor with, where the genomic risk sits, and how to patch fertility, type, or feet and legs without blowing up gPFT. If you’ve got more than 200 cows on Italian or MACE semen and haven’t audited your sire sheet since December, this run is big enough to justify a 30‑minute rethink.

Italian gPFT rankings

Crisalis RF just widened the gap. The Gywer son added +67 gPFT points between the December 2025 and April 2026 Italian evaluations (ANAFIBJ, data updated April 1, 2026) to reach gPFT 5247 — and then his own son Boero graduated from the genomic list straight to #2 proven at gPFT 5162. That’s the first father-son 1-2 on Italy’s domestic daughter-proven gPFT ranking in recent memory, and it signals something bigger: the proven tier is no longer just catching up to genomic projections — it’s compressing hard toward them.

Across all four ANAFIBJ lists (domestic genomic, domestic proven, foreign genomic, foreign proven), this run reshuffled the proven ranks more aggressively than any Italian evaluation since early 2025. Five new bulls entered the domestic proven top 10. The proven top-10 average leaped +153 points (from 4934 to 5087, December 2025 vs April 2026 gPFT). Meanwhile, the domestic genomic top group barely moved (+61 points on average), and the spread between #1 and #10 compressed from 203 to just 144 points — making it harder than ever to separate genomic contenders on index alone.

Here’s what it all means for your matings this spring.

What Changed at the Top?

Domestic Genomic: Stability With Two New Faces

The domestic genomic top 10 is the calmest list this run. Eight of ten bulls held their positions from December 2025. Ecbert (Gladius × Dateline) remains #1, edging from gPFT 5349 to 5371 (+22, April 2026 Italian gPFT). Rascasse (Vivify × Geyser P) is again #2 at gPFT 5342 (+21).

The two new entrants both bring distinctive packages:

BullSire × MGSApril 2026 gPFTKey Trait Notes
Bangles(Isolabella)Pacific × Royalflush5310Udder composite +2.68, Longevity 119, Fertility 111 — the health-and-type specialist in the top group
Mirosh (Go-Farm)Reunion × Mookie5296+0.52% Fat, +111 Kg Fat, IQC 108 — a components-first bull

They replaced Stormur (dropped to gPFT 5216, rank ~11) and Enola (gPFT 5165, rank ~17). Neither dropped dramatically — this is normal genomic shuffling, not collapse.

Top-group compression is the real story. The gap between Ecbert (#1, gPFT 5371) and Jegolo (#10, gPFT 5227) is just 144 points, down from 203 in December 2025. With all ten bulls carrying Rk 99 (ANAFIBJ’s top reliability band for genomic sires), this tight clustering means the rank order within the top 10 could easily reshuffle in the next run. Treat positions 3–10 as essentially one band.

Domestic Proven: The Big Reshuffle

This is where the action is. Five of the December 2025 top 10 dropped out, and five new bulls entered — a 50% turnover rate that’s unusually high for Italy’s proven tier.

* Boero was listed at gPFT 4932 on the December 2025 genomic domestic list; he has now transitioned to the proven list. ** Glorydays was on the December 2025 genomic domestic list at gPFT 4901; his proven debut at 5056 is a +155-point jump.

Dropped from the proven top 10: NT Isarco (was #6, gPFT 4871 Dec 2025 → gPFT 4951 Apr 2026, now rank ~12), SFH Redshift R (was #7 → gPFT 4941), Wilder Holocron (was #8 → gPFT 4937), KNO Ecuador P (was #9 → gPFT 4941), and Barone Rosso R (was #10 → gPFT 4885). Notably, most of these bulls gained points but still fell out of the top 10 — the new entrants pushed the floor higher.

The proven top-10 spread compressed from 346 points (December 2025: 5180 to 4834) to 242 points (April 2026: 5247 to 5005). That’s still wider than the top 10 in the genome, but the gap is closing fast.

The Big Movers: Up, Down, and In

Biggest Gainers (Proven Domestic)

  • Glorydays: +155 gPFT transitioning from genomic to proven debut at 5056 — his daughters confirmed a Gladius-line profile of solid ICS-PR (€957) with strong Longevity (111) and above-average Fertility (104), April 2026 Italian gPFT.
  • Wendat: +128 gPFT (4880 → 5008) — now carrying Rk 99 with a balanced Kg Milk (1182), components (Kg Fat 62, Kg Pr 70), and Longevity (110).
  • Royal Inseme Carlomagno: +72 gPFT (5068 → 5140) — held #3 and narrowed the gap to Boero by delivering higher Protein % (+0.26) and the best Kcas rating (BE) in the proven top 5.
  • Crisalis RF: +67 gPFT (5180 → 5247) — extended his #1 lead to +85 points over Boero, driven by improved SCS (107), while his production base held steady (Kg Milk 1189, Fat% +0.16, Pr% +0.20).

Genomic Graduates Worth Tracking

Boero and Glorydays both performed better than their genomic predictions. Boero’s December 2025 genomic gPFT was 4932; his April 2026 proven gPFT is 5162 — a +230-point gain that likely reflects an accumulation of more daughter data. Glorydays jumped from 4901 genomic to 5056 proven. Both are Rk 99 with high reliability — these are durable results, not noise.

Who Slid?

No dramatic collapses this run. The biggest relative loser in the proven top 20 is Sebulba (was gPFT 4786 in Dec 2025; no longer in the April 2026 top-20 visible range, with 93 bulls published). The drop-outs from the top 10 (NT Isarco, Redshift, Holocron, Ecuador, Barone Rosso) all actually gained 70–100+ points but were outpaced by the new entrants.

What Is Italy’s gPFT Rewarding This Run?

The April 2026 proven top 10 is skewed more heavily toward components and ICS-PR economic value than December’s list.

Trait ShiftDec 2025 Proven Top-10 ProfileApr 2026 Proven Top-10 Profile
Top-10 avg gPFT49345087 (+153)
Avg ICS-PR (€)~770~870 (estimated from top-10 values)
Avg IQC~106~109 (higher cheese-yield emphasis)
Avg Longevity~108~109
Avg Fertility~106~105 (slight dip)

The top group now has higher averages for Kg Fat and Kg Protein, and IQC (cheese quality) has firmed up. This reflects Italy’s Parmigiano-Reggiano premium: the gPFT formula inherently rewards cheese-relevant traits, and the bulls whose daughters deliver high-component, high-casein milk are being rewarded disproportionately as more data accumulates.

On the genomic domestic side, the Vivify sons (Rascasse, Liverpool, Odino — three of the top 8) dominate the health-and-type sub-indexes: Liverpool carries Udder composite +1.96, Fertility 112, and Type 110 (April 2026 Italian gPFT). But Mirosh (Reunion × Mookie) breaks that mold with a pure components play: +0.52% Fat, 111 Kg Fat, and only average health traits (Fertility 108, Longevity 104). Ecbert (Gladius × Dateline) bridges both profiles — IQC 111, solid IES (€1148), and balanced health.

Trade-off to watch: The proven #1 Crisalis RF (gPFT 5247) carries the weakest Type score in the top 5 (Type 0.94 →his weakest area in the top 5). If your herd needs functional type improvement alongside index, look further down the list to Distefano (Type 1.75, Udder 2.81) or Glorydays (Type 0.46, F&L 0.88 — moderate but balanced).

AI Companies and Bloodlines: Who Owns the Italian Top?

AI Center Shifts

Intermizoo continues to dominate the domestic proven top 10, holding 5 of 10 slots in April 2026. But the notable shift is what’s happening with the Italian Genetics → Inseme transition. In December 2025, Distefano and Barone Rosso were listed under “ITALIAN GENETICS” as their AI center. In April 2026, Distefano now appears under “INSEME.” Similarly, on the genomic domestic list, both Stormur and Jegolo switched from Italian Genetics to Inseme between runs. This almost certainly reflects the Inseme rebrand/restructuring — not a marketing shift, but a real organizational consolidation that breeders sourcing Italian semen should note for ordering purposes.

On the foreign genomic list, the distribution is broader. Novagen holds 4 of the top 10; Inseme has 2; Semex Italia has 2; and ABS Italia, Cosapam, and ST Gen Group hold 1 each. The Novagen concentration is driven by their Peak and Smartie P connections.

Bloodline Concentration

Vivify is the dominant sire in the domestic genomic top 10, with three sons (Rascasse, Liverpool, Odino) plus Stormur just outside at #11. This is a significant concentration risk for breeders relying heavily on this list for matings — if you’ve already used two Vivify sons, your next genomic pick from Italy’s top group is likely to be Ecbert (Gladius), Bangles (Pacific × Royalflush), or Mirosh (Reunion × Mookie).

Gladius has emerged as the cross-list anchor sire:

  • Ecbert (#1 domestic genomic, gPFT 5371) — sired by Gladius
  • Delta Morgan (#8 foreign genomic, gPFT 5446) — sired by Gladius
  • Gigantic (#3 foreign proven, gPFT 5212) — sired by Gladius
  • Gladius himself ranks #4 foreign proven at gPFT 5173

That’s four top-10 placements across three different lists for the Gladius sire line. Any breeding program that has used Gladius, Ecbert, Morgan, and Gigantic all needs to audit its mating list for inbreeding coefficient stacking.

Rad sons dominate the extended foreign genomic list (Lightsaber gPFT 5440 in the top 10, plus Judo gPFT 5421, Rad Lad gPFT 5406, Beige gPFT 5410, and Ballot gPFT 5266 in the top 20). However, most Rad sons carry below-average F&L (Feet & Legs) scores — Lightsaber at -0.99, Judo at -1.13, Rad Lad at -0.05. For herds with concrete-floor housing, that’s a real functional risk despite the index appeal.

Outcross space: Bangles (Pacific × Royalflush) and Mirosh (Reunion × Mookie) on the domestic side, and Smartie P (Sega P RDC × Arrozo) on the foreign side, offer the cleanest pedigree breaks from the Vivify-Gladius-Rad concentration.

How Volatile Are Italy’s gPFT Rankings Right Now?

Domestic genomic: Low volatility. 8 of 10 held, 2 entered, top-10 spread compressed from 203 to 144 points. The Ecbert-Rascasse 1-2 looks stable; both gained modest points. Genomic bulls at Rk 99 in Italy carry high reliability within the genomic framework, but these are still genomic predictions — treat any individual bull’s exact rank as provisional. The tight 144-point band means a ±50-point swing in the next run could significantly reshuffle positions 3–10.

Domestic proven: High volatility by Italian standards. 50% top-10 turnover, +153-point average gain, and multiple genomic-to-proven graduates entering the list. This isn’t instability in the system — it’s the proven tier catching up as large daughter groups report. The Rk 99 designation on all top-10 proven bulls means these evaluations are high-reliability. Crisalis RF at #1 is about as safe a bet as Italy’s proven list offers.

Foreign genomic: The top of this list is genomic-only and subject to the usual re-ranking risk. Locust (gPFT 5527, April 2026) leads by just 8 points over Tiberius (5519). Both are Rk 99, but with no Italian daughter data, their gPFT is MACE-derived from their home-country genomic predictions. International breeders should weigh these as directional rather than definitive for Italian conditions.

Foreign proven: Powerhouse (gPFT 5394) has a commanding 165-point lead over Percival (5229). Powerhouse is heavily daughter-proven globally; his Italian gPFT is among the most reliable numbers on any of these lists. Percival at #2 is also well-proven (Captain × Gymnast, Rk 99) with 2011 Kg Milk and strong Kg Fat (125) — a Volume + Fat specialist.

What This Means for Your Matings This Spring

All recommendations below reference April 2026 Italian gPFT evaluations (ANAFIBJ, data updated April 1, 2026). Every bull discussed is Rk 99 unless otherwise noted.

If Your Herd Prioritizes Cheese Yield and Component Value (Parmigiano-Reggiano / Grana Padano Herds)

The proven list gives you Crisalis RF (gPFT 5247, IQC 101, Kcas AA) and Boero (IQC 114, Kcas AA) as the obvious father-son pair — but watch the IQC gap: Boero’s 114 vs Crisalis’s 101 means Boero contributes more directly to cheese-quality economics. If you need casein kappa genetics, Mantra (IQC 113, Kcas BB, +0.46% Fat, +88 Kg Fat) is the proven-tier cheese specialist. On the genomic side, Mirosh (IQC 108, +0.52% Fat) and Saxony (IQC 108, +0.47% Fat) offer strong component packages.

Be cautious with: Locust and the Rad sons (foreign genomic) carry high milk volume but relatively lower IQC scores (106 and 107, respectively); for cheese-yield herds, volume without components can dilute vat efficiency.

If Your Herd Prioritizes Health, Longevity, and Fertility

Liverpool (genomic domestic, gPFT 5267, Fertility 112, Longevity 114, Udder +1.96) is the standout functional bull in Italy’s genomic top group. On the proven side, Distefano (Longevity 115, Fertility 110, Udder +2.81) has the best health-trait package in the proven top 10 — and he’s now fully daughter-proven at Rk 99.

If your conception rate is below 40%: Prioritize Fertility scores above 110. Liverpool, Distefano, and the genomic newcomer Faktor (Fertility 116, Longevity 117, gPFT 5152, April 2026) are your short list. Avoid Crisalis RF (Fertility 107 — solid but not a specialist) if fertility is your limiting factor.

If You Run a Robot Herd

Udder composite and milking speed (IMA) matter. On the domestic proven list, Distefano leads with Udder +2.81 and IMA 106. Crisalis RF carries Udder +1.76, IMA 107. On genomic, Bangles (Udder +2.68, IMA 106) is the robot-herd pick from the new entrants.

Avoid for robot herds: Mirosh (Udder -0.25) and any Rad son with negative F&L scores — lameness and poor udder attachment will cost you throughput in a robotic system.

If You Show or Sell Seedstock (Type-Focused Program)

Distefano (Type 1.75, Udder 2.81, F&L 1.12, proven gPFT 5053) is the clear type improver with a competitive index. On the genomic side, Bangles (Type 1.62, Udder 2.68, F&L 1.39) offers the Royalflush maternal line — useful for mating programs targeting both type and outcross pedigrees.

Trade-off: Crisalis RF (Type 1.25) and Boero (Type 1.01) are fine for commercial herds but won’t win you type competitions.

If You Want to Anchor With Proven Safety

Use Powerhouse (foreign proven #1, gPFT 5394, Rk 99 with deep global daughter data) as your portfolio anchor. His 1750 kg of milk, +136 kg of fat, and +102 kg of protein are among the highest absolute production numbers on any Italian list. Pair him with a health-trait specialist like Distefano or Liverpool to offset his weaker Fertility (97) and Type (F&L +0.36).

30-Day Action Items

  1. Audit your Gladius and Vivify exposure. If more than 30% of your matings from the last 12 months trace to either sire line, flag those females for outcross matings using Bangles, Mirosh, or Smartie P this cycle.
  2. Pull your current mating list and cross-check against the April 2026 proven movers. If you were using NT Isarco, Redshift, or Holocron based on their December rank, they haven’t collapsed — but the new entrants (Boero, Gewiss, Smilodon, Glorydays, Noyz) offer fresher daughter data and a higher index.
  3. Re-evaluate any Rad-son heavy lineups for F&L risk, especially in housed herds on concrete. If you can’t give up the index, at a minimum, pair Rad sons with dams that carry positive F&L proofs.
  4. If you source from Italian Genetics / Inseme: Confirm your ordering codes and semen inventory labels reflect the consolidated Inseme branding — some catalogs may still list these bulls under the old Italian Genetics name.

Key Takeaways:

  • Crisalis RF and his son Boero now sit 1–2 on Italy’s April 2026 proven gPFT, with Crisalis up +67 points and five new sires pushing into the proven top 10.
  • The proven top-10 average jumped +153 gPFT in four months, meaning a “safe” December sire lineup can now be 150+ index points off the pace in Italy.
  • Domestic genomic rankings stayed stable but compressed into a 144‑point band, so fine‑tuning off who’s #3 vs #8 makes less sense than picking by trait package and risk.
  • Vivify and Gladius blood heavily dominate the top genomic and foreign lists, creating real inbreeding risk if 30%+ of your recent matings already trace to those lines.
  • There’s genuine upside in this run—Boero, Glorydays, Mantra and a few others proved up better than their genomic calls, especially for high‑component and cheese‑milk herds.

CAPTAIN Gained 369 TPI Points. HOMECOMING Lost 414. Inside the 59% Failure Rate of April 2020’s Top Genomic Sires

Tuesday, March 17th, 2026

We tracked 401 genomic Holstein bulls from April 2020 to their December 2025 daughter-proven proofs. Most never showed up. The ones that did reshuffled everything.

In April 2020, a lot of breeders logged into that proof run feeling like it was draft day. Lists of sky-high GTPI young bulls, reps pushing “can’t-miss” sires, and mating programs swinging hard toward genomics overnight. Five years later, the December 2025 CDCB/HAUSA proofs told a very different story in the U.S. Holstein system: 59% of those “elite” genomic Holstein bulls never made it to a daughter-proven proof at all, while a small group of outliers like Genosource CAPTAIN didn’t just hold — they gained hundreds of TPI points.

This is the reality check on that April 2020 class: who vanished, who climbed, what changed under the hood of TPI, and what it should do to the way you build your sire stack going into 2026.

How We Tracked the 2020 Class

Before we get into winners and wrecks, here’s where these numbers come from.

The Bullvine pulled an “elite” group of 401 genomic Holstein bulls from the April 2020 U.S. CDCB/HAUSA evaluations, based on their GTPI at that time. We then followed those same bulls forward to their December 2025 U.S. proofs, recording who made it to a daughter-proven evaluation, how their TPI changed, and which AI stud carried their semen.

Every cohort-level average and stud-level number you’ll see here describes this 401-bull slice over that five-year window. It’s not claiming to represent every bull each stud owns.

401 Genomic Bulls. 236 Never Showed Up.

In April 2020, the Holstein genomic pipeline looked unstoppable. The top of the GTPI list was stacked with young sires promising big jumps in milk, components, and type.

MetricCount% of Total
Total April 2020 Elite Bulls401100%
Bulls with December 2025 Daughter Proof16541%
Bulls That Never Proved23659%

By December 2025, only 165 of those bulls — 41% — had an official daughter-proven proof in the U.S. system. The other 236 bulls — 59% — never showed up with a CDCB/HAUSA daughter proof at all. No proof. No official daughters in the data.

Some of that attrition was straight biology. Many of those bulls came out of aggressive IVF programs and shortened generation intervals — great for genetic gain, not always great for semen production, health, or simply living long enough to matter. The rest was institutional: as soon as higher-index sons and half-brothers hit the lists, studs quietly retired a lot of 2020 calves before their first daughters ever calved.

If you bred heavily to April 2020 genomics, a big slice of the “genetic potential” you were sold never even got the chance to prove itself in your bulk tank — or anyone else’s.

How Accurate Were the April 2020 Rankings?

The 59% failure rate isn’t the whole story. Among the bulls that did survive to a December 2025 proof, the ranking shuffle was just as important.

  • Of the Top-10 genomic bulls in April 2020, 8 eventually got a proof, but only 4 were still in the proven Top-25 by December 2025.
  • Of the Top-25 genomic bulls, 21 got a proof; just 9 held a Top-25 spot.
  • Of the Top-100 genomic bulls, 74 got a proof; only 14 were still Top-25.

That means only 36% of the Top-25 bulls from April 2020 were still Top-25 five years later. Genomics clearly did a solid job flagging an “elite” pool. The fine sort between #1 and #25 turned out to be noisy once real daughters, base changes, and formula rewrites landed.

Underneath that index whiplash, the biology held up better than the rankings suggest. Correlations between 2020 genomic predictions and 2025 proven proofs stayed strong for core biological traits: 0.814 for PTAT, 0.762 for fat yield, 0.709 for protein yield.

Genomics did a pretty good job on pounds of fat and protein and general type. The volatility came from what the formula decided those traits were worth over time — not from the underlying DNA suddenly changing its mind.

Why Your Bull’s TPI Dropped Even if His Genetics Didn’t

You can’t stack a 2020 GTPI beside a 2025 proven TPI and read it straight. The ground moved under every bull in three big ways.

The 2025 Base Change: The Big Rollback

In April 2025, CDCB reset the Holstein genetic base from cows born in 2015 to cows born in 2020. The breed made serious progress in that window, so every bull’s PTA got pulled back:

  • Milk: −650 lb
  • Fat: −38 lb
  • Protein: −26 lb
  • Productive Life: −2.31 months
  • Somatic Cell Score: +0.10

For bulls in this 401-bull cohort that made it to December 2025, the average TPI drop was about 42.5 points, just from living through that base reset and the other formula changes. Expected Future Inbreeding (EFI) climbed from 7.5% to 9.4%, which added extra pressure on certain pedigrees.

So if you saw a favorite bull lose a chunk of TPI over those five years, part of that was simply the yardstick moving.

Feed Efficiency and Feed Saved: Penalties for Big, Hungry Cows

In April 2021, Holstein Association USA rewrote the TPI formula to pull Feed Saved into the mix. The revised feed efficiency term leaned hard into solids and efficiency, not just raw volume:

FE$=(-0.0025×PTA Milk)+(1.86×PTA Fat)+(1.75×PTA Protein)+(0.13×Feed Saved)

Bulls that made big, heavy daughters with high body weight composite (BWC) — and big maintenance bills — started paying a TPI penalty, even if their milk PTAs looked flashy. That was bad news for “bigger is better” pedigrees whose value had been built on sheer volume. And very good news for moderate-framed cows that quietly pounded out components without eating the farm out of house and home.

DPR Couldn’t Carry the Fertility Load Alone Anymore

By August 2024, the Fertility Index was also rebalanced. DPR had been 70% of that index. After the change, DPR and Cow Conception Rate (CCR) each carried 40%, with Heifer Conception Rate (HCR) and Early First Calving (EFC) at 10% each.

Any 2020 bull whose genomic TPI leaned heavily on extreme DPR, but didn’t have the CCR to back it up, took a hit. The new math rewarded bulls that actually got cows bred on first service, not just bulls whose daughters came back into heat quickly after a miss.

Put those three shifts together, and you get the pattern: genomics did a decent job on biology; the index moved underneath them.

CAPTAIN: +369 Points, 12,000 Daughters, 99% Reliability

One sire didn’t just ride out those hits. He used them.

Born on New Year’s Day 2019 in Iowa, the Charl × Sabre calf spent his first six months at Farnear Holsteins. “With his very promising gTPI, everyone doted on him,” recalled Tom Simon from Farnear. Genosource’s Tim Rauen had flagged Captain early, calling him “a long-term deal” during a conversation in Madison in October 2019 — months before the bull would debut at 3059 GTPI in April 2020.

Most of his peers dropped from their genomic starting point once the base changed and the formula shifted. Captain went the other way.

By December 2025, Captain was sitting at 3428 TPI, a gain of 369 points from his 2020 genomic estimate. His proof at that time pulled from over 12,000 daughters in nearly 800 herds under U.S. CDCB/HAUSA evaluations. His daughters averaged 32,542 lb milk with +123 lb fat and +64 lb protein, and his milk reliability sat at 99%.

That’s not an opinion. That’s a bull whose daughters out-delivered the genomic math while the formula got tougher. “He is without a doubt, the best bull that the breed has ever seen,” STgenetics CEO Juan Moreno has stated publicly — and in this case, the proof file backs up the claim.

Captain’s profile — heavy on components, efficient frames, and enough fertility to hold value under the 2024 FI rewrite — was effectively built for the TPI of the future, not the one we were using in 2020. He’s not faultless. Rauen himself has noted Captain needs to be “protected for somatic cell” and watched on overall conformation, strength, foot angle, and teat length. But the production engine underneath is something the breed hasn’t seen before at this reliability level.

Barn Math: Captain vs. Homecoming in Your Milk Cheque

“Captain over-performed” sounds nice. Let’s put a dollar figure on it.

On the December 2025 U.S. proof run, Captain’s PTA stands at +67 lb protein and +120 lb fat per lactation. The average bull in this April 2020 proven cohort sits at +29 lb protein and +64.9 lb fat. That gives Captain an edge of roughly:

  • +38 lb protein
  • +55.1 lb fat

per daughter per lactation versus the class average.

Using January 2025 U.S. FMMO Class III component prices — $2.33/lb protein and $2.95/lb butterfat (per USDA/AMS) — that component gap works out to roughly $250 per cow per year in extra component revenue compared with the average bull in this group.

Put that in your own barn. If Captain sires half the replacements in a 300-cow herd, once those daughters are in full production, you’re looking at around $37,500 more in component revenue per year than if you’d used the cohort average instead. On a 1,000-cow operation, that gap jumps to roughly $125,000 per year. That’s not a rounding error — for a lot of upper Midwest freestall herds, it’s the difference between making the principal payment comfortably and sweating every month.

Now flip it with AOT HOMECOMING. His proven PTAs landed at −5 lb protein and +6 lb fat. Versus Captain, that’s about:

  • 72 lb less protein
  • 114 lb less fat

per daughter per lactation. At the same component prices, that’s in the ballpark of $500 less per cow per year in component revenue for a Homecoming daughter than for a Captain daughter.

BullProtein PTA (lb)Fat PTA (lb)Component Revenue/Cow/Year (USD)
CAPTAIN+67+120~$510
Cohort Average+29+64.9~$260
HOMECOMING-5+6~$0
Captain vs. Homecoming Gap+72 lb+114 lb~$500

Both bulls were available to you in essentially the same era. The semen price gap wasn’t $500 a straw. But the long-term revenue gap per cow per year is right there on the pay stub. Run the same math with your own component prices and herd size — the method is the same even if your numbers differ.

The Siemers Renegad Parfect Surprise

If Captain is the headline, Siemers Renegad Parfect is the bull a lot of people skimmed past in 2020 — and shouldn’t have.

In April 2020, Parfect sat at #150 on the genomic TPI list with 2980 gTPI. Solid, but a long way from the Top-10. By December 2025, he had 19,079 daughters in 2,627 herds — the highest daughter count of any bull in this 401-bull dataset — and his TPI climbed to 3124, a gain of 144 points. He’s also the only bull in the 165-head proven group whose PTAT went up: from +1.80 genomic to +1.88 proven.

A Renegade × Delta-Lambda × Denver from the Siemers Lmda Paris family, Parfect has sold approximately 450,000 units of semen worldwide with 24% sexed and 35% sold outside the U.S., and he remains an allocated bull because demand keeps outrunning production, according to Select Sires. Paris herself was a Global Cow winner with GMD and DOM designations and more than 20 sons to AI — and there are already 76 bulls released from Parfect dams.

At Trent-Way Holsteins in Wisconsin, Trent Hendrickson calls Parfect a “generational talent” for their black and whites, describing daughters that are well-balanced, with positive milk, strong components, and consistent udders and rumps.

None of that makes Parfect bulletproof — it just shows that in this cohort, he’s one of the rare bulls whose proof climbed with massive daughter numbers behind him. When 19,000+ daughters tell the same story, you’re past the “small sample” excuse and into something real.

When the “Can’t-Miss” Genomic Bulls Missed Hard

On the other side of the ledger sit the crashes.

CAPTAIN30593428+36912,170Charl x Sabre x Ahead

HOLDON29803091+1112,937Charl x Draco x Numero Uno
DUFFY30253152+1271,979Acura x Rio x Modesty

The bulls that fell more than 300 TPI points between April 2020 genomics and December 2025 proofs share a familiar pattern:

  • HOMECOMING (Spartacus × Delta × Day): −414 TPI points, with PTAT dropping 0.87 points.
  • SUPERCHARGE (Legacy × Rubicon × Morgan): −396 TPI points, including a 2.32-point collapse in PTAT (from +1.18 to −1.14).
  • TYCOON: −352 TPI points, mainly from yield under-performance.
  • SHINE: −327 TPI points, driven by fertility and health erosion.

In the worst of these crashes, the structure is the same: over-predicted type stacked on weak or shallow functional traits. Sire lines heavy on Legacy and Heroic on the top side, with Delta on the maternal side, were over-represented.

Supercharge is the clearest example. His genomic PTAT was built on a stack of fashionable type sires and early pedigree data. Once his daughters hit real commercial parlors, the structure didn’t hold up — and the index followed.

For breeders who leaned hard into those pedigrees, the disappointment wasn’t a chart. It was cows that didn’t do the job they were supposed to do.

Does More Semen in More Herds Really Make Proofs Worse?

You’ve heard it at the coffee shop: “Once a bull goes everywhere, his proof will just get worse.” This class gives you a cleaner answer.

Group the 165 proven bulls by how many daughters they had in December 2025, and the pattern is pretty clear:

Proven daughtersBullsAvg TPI change% that gained TPI
Under 50052−81.828.8%
500–1,00029−65.524.1%
1,000–2,00027−23.433.3%
2,000–5,00042−27.940.5%
5,000+15+62.366.7%

Bulls with 5,000+ daughters actually gained TPI on average, and two-thirds of them went up, not down. Bulls with fewer than 500 daughters lost an average of almost 82 points, with fewer than a third improving.

A few big-use sires from this group:

  • Siemers Renegad Parfect: 19,079 daughters, +144 TPI.
  • Larcrest Captivating: 14,777 daughters, −122 TPI.
  • Mr. Farnear Helix Twitch: 12,480 daughters, −246 TPI.
  • Sandy-Valley R Conway: 12,411 daughters, +22 TPI.
  • Genosource Captain: 12,170 daughters, +369 TPI.

Once you’re past around 5,000 daughters in a few hundred herds, what you see is basically what you get — good or bad.

For your own herd, this dataset says one thing: treat daughter and herd counts as filters, not afterthoughts. A bull with 300 daughters in 20 herds is still on trial. A bull with 2,000 or 5,000 daughters spread over hundreds of herds is telling you who he really is.

Which Studs Got It Right — and Which Got Burned?

This five-year window didn’t just sort bulls. It showed which AI programs were actually breeding for the new economics and which ones were still built around the old index.

All stud-level averages and retention rates here come from The Bullvine’s analysis of that 401-bull April 2020 cohort through the December 2025 U.S. proofs — not every bull each stud owns.

AI StudBulls in April 2020 Elite GroupBulls with Dec 2025 ProofRetention Rate (%)Avg TPI Change (Retained Bulls)
STgenetics361438.9%+21.8
PEAK361952.8%-36.0
Select Sires1064340.6%-32.9
ABS Global1967739.3%-70.6
Cohort Average40116541.2%-42.5

STgenetics: Building for the Index of the Future

In this look-back, STgenetics came out on top.

They were the only major stud whose retained bulls gained TPI points on average, at about +21.8 TPI per bull across the group. That lift was anchored by Captain and his clone brothers Jack and John, but it went deeper — bulls like HOLDON (+111) and JARVIS (+76) also posted gains.

That pattern lines up with ST’s long-running focus on Chromosomal Mating and their EcoFeed program — both targeting feed conversion and solids years before those traits were fully rewarded in the TPI formula. For a commercial herd, that meant ST-sired daughters were better positioned than most when the formula turned on big, hungry cows and rewarded efficient ones.

For more on the four foundation sires shaping almost every Holstein pedigree you touch today, see our deep dive.

Select Sires: High Ceiling, Deep Floor

Select Sires landed in the middle of the pack, but with a wide spread.

They retained 43 bulls (40.6%), a better survival rate than the group as a whole, and those bulls dropped an average of −32.9 TPI points, beating the overall cohort decline. They also owned 16 bulls that gained points, including PAYLOAD, CRUSHER, and GAMEDAY.

But Select also held four of the six worst crashes in this analysis, including HOMECOMING and SUPERCHARGE. If you spread your matings across their lineup, you probably did fine. If you concentrated on a couple of high-PTAT pedigrees that later deflated, December 2025 may have been a painful read.

PEAK: The Safe Center

PEAK showed up as the most stable of the majors.

They had the highest retention rate, successfully proving 19 of 36 bulls (52.8%), and their retained bulls dropped an average of −36.0 TPI points. No moonshot 300-point gainers. No catastrophic 300-point crashes.

PEAK’s strategy leaned into balanced, predictable genetics that mostly held their rank even as the base and formula moved. Sires like ZILLION and ALTAZAZZLE became quiet anchors in that approach. If your breeding philosophy values predictability over fireworks, this is the sort of stud profile that lets you sleep at night.

ABS Global: Exposed to the Old Index

In this particular 2020 look-back, ABS Global had the roughest ride.

They started with the most bulls on the 2020 elite list, but recorded the lowest retention rate — 39.3% (77 bulls) — and their retained bulls dropped an average of −70.6 TPI points, the steepest decline among the major studs in this dataset.

Many of their high-profile young sires at that time were built on extreme DPR and high-milk, larger-framed daughters. Once feed efficiency and CCR were given more weight in TPI, those profiles were more exposed than some competitors’ lineups. There were bright spots — bulls like ENVY (+193) — but the volume of Heroic and Prince sons that fell off pulled their stud average down.

ABS has been adjusting. They introduced 36 new Holstein graduates following later sire summaries, a sign they’re working to realign with updated TPI standards and market demands.

Genomics Got the Biology Right. The Index Is What Moved.

The biggest takeaway from this April 2020 class is simple: don’t confuse index volatility with genomic failure.

  • The average retained bull dropped 42.5 TPI points over five years, driven largely by base changes and formula shifts, not by failed biology.
  • The correlations between 2020 genomic predictions and 2025 proofs stayed strong for core traits: PTAT around 0.81, fat around 0.76, protein around 0.71.

The core question for your breeding program isn’t “Does genomics work?” It’s “Am I breeding for the index and milk cheque of the next five years — or the one that just got retired?”

For more on how the genomic model reshaped what “elite” even means, read our primer on genomic selection’s real track record.

What This Means for Your Operation

You don’t control base changes or formula tweaks. You do control how much risk you take, which studs you trust, and how you weight solids, fertility, and efficiency when you pick bulls.

  • Audit your reliability stack within 30 days. Print your current sire list and match it against the December 2025 U.S. CDCB/HAUSA proofs. Any bull under 70% reliability on TPI? Treat him as a genomic young sire in practice, even if he technically has some daughters. Any bull above 90% reliability with daughters across multiple herds is your stability layer — the Captain/Gameday-type bulls that absorb shocks when formulas move. Any sire list where three young bulls cover more than half your matings should be a red flag, given the 59% attrition this class showed.
  • Balance proven vs. genomic on purpose, not by accident. For a commercial Holstein herd, a pragmatic split looks like 50–70% of matings on a small group of high-reliability proven sires whose daughters do exactly what the current TPI and milk cheque care about — solids, fertility, efficiency — and 30–50% of matings on genomic sires spread across at least 4–6 different lines.
  • Run a type-fragility check before you chase the next PTAT rocket. The bulls that crashed hardest here — Homecoming, Supercharge, Shine — weren’t derailed by milk. They were derailed by over-predicted type and weak functional traits, especially once base and formula changes hit. Before you lean into the next big PTAT bull, look at his sire and MGS proof history and his health/fertility stack. If the pedigree is all type and no ballast, keep that semen for donors and show projects — not across the whole freestall herd.
  • Respect daughter and herd counts as filters, not fine print. A bull with 300 daughters in 20 herds is still on trial. A bull with thousands of daughters in hundreds of herds is telling you who he really is, for better or worse. Make that filter part of your mating program, not a footnote you glance at after you’ve picked the bull.
  • Align with solids and efficiency economics. U.S. component pricing and export data are pointing the same direction: fat and protein drive the cheque, and global demand is solids-hungry. Pick sires that put more fat and protein in the tank at realistic feed costs — the new FE$ and Net Merit formulas are already paying those cows differently. For the economics that now reward solids and efficiency over sheer volume, see our analysis of the $1.6B dairy shift.

Key Takeaways

  • If you build your sire list only from the very top of a genomic ranking, you’re accepting that roughly 6 out of 10 “elite” bulls may never even see a daughter-proven proof; to manage that risk, blend proven stability with genomic upside.
  • If you see a bull drop 100–150 TPI points between 2020 and 2025, don’t panic; check how much of that is base change and formula moves versus real trait erosion before you write him off.
  • If a high-PTAT young sire’s pedigree leans hard on Legacy/Heroic/Delta lines and doesn’t bring matching health and fertility, treat him as a specialist tool for donors and show cows — not as a herd-wide solution.
  • If you’re choosing between two bulls available at the same time, and one puts an extra 90–100 lb of combined fat and protein into each daughter’s tank at current component prices, assume that’s worth several hundred dollars per cow per year and make your semen budget reflect it.

The Bottom Line

Genomics is still the sharpest tool in the shed. But if you love speed and are willing to absorb some crashes, you’ll keep leaning into young sires. If you’d rather sleep at night, let bulls like Captain and Parfect carry most of the weight while genomics scouts the next generation. The difference between a well-diversified strategy and a concentrated one is the difference between Captain and Supercharge.

Pull up your semen invoices from 2020–2021 and your December 2025 proof file. How many of those bulls are still earning their keep under today’s rules — and how many were gone before their daughters hit a parlor?

Canada’s 20 Most-Used Holstein Sires: 96th Percentile LPI, Yet Only 31st Percentile Fertility

Wednesday, March 11th, 2026

Canada’s 20 most-used Holstein sires average 96th percentile LPI — and only 31st percentile where it costs you cows: fertility.

Lactanet’s new subindexes reveal a pattern hidden within elite proof sheets — and it runs through nearly a quarter of every registered calf born in 2025. Seventeen of Canada’s twenty most-used Holstein sires rank below the breed-indexed midpoint for reproduction.

A2P2 PP – Canada’s #1 registration sire in 2025 – delivers elite LPI, high type, A2A2 and polled genetics, while this article asks what his proof sheet isn’t telling you about fertility.

Not below the top quartile. Below the middle! These aren’t marginal bulls filling tanks at small operations — they’re the bulls shaping roughly 23% of all Canadian Holstein registrations in 2025, averaging about 2,940 daughters each, according to Holstein Canada data. A2P2 leads the list. Fuel sits at number twenty. On the December 2025 Lactanet proof sheets, the twenty average LPI hits 3,568 — the 96th percentile. By any traditional measure, this is an outstanding working sire team.

But Lactanet launched a modernized LPI in April 2025 with six new subindexes — and those subindexes tell a story the headline number doesn’t.

Who’s Actually Doing the Breeding?

The top-20 registration list reads like the semen order form at half the barns in the country:

RankBullRankBull
1A2P211Right Stuff PP
2Pursuit12Bullseye
3Anahita13Poprock
4Johnboy14Zippy
5Knowhow15Capone
6Alcove16Landfall
7Zoak17Troy
8Renegade18Lehigh
9Conway19Lateshow
10Ambrose20Fuel

A2P2 at number one — polled, A2A2, daughter-proven with elite Conformation — would have been unthinkable at the top of a registration chart five years ago. Right Stuff PP at eleven reinforces the point: polled genetics aren’t a show-barn curiosity anymore. They’re mainstream enough to dominate usage. The group includes a mix of daughter-proven and genomic-only sires. When The Bullvine analyzed the 2021–2023 registration data, 29 of the 53 most-used sires (55%) were genomic, but they accounted for just 36.4% of actual registrations. The genomic share on this 2025 list suggests that the gap has narrowed — breeders aren’t just accepting genomic sires anymore, they’re choosing them first.

96th Percentile LPI, Yet Only 31st on Fertility — How?

The December 2025 top-line indexes for this group look genuinely impressive:

  • LPI: 3,568 average (96% RK)
  • Production Index (PI): 92% RK
  • Longevity & Type Index (LTI): 97% RK
  • Pro$: about 2,008 (around 93% RK)

If you stopped reading there, you’d think Canadian breeders had assembled the strongest working lineup in the breed’s history.

Then you read the subindexes.

When Lactanet rolled out the modernized LPI in April 2025, six subindexes replaced the old two-pillar structure, each on a standardized scale (average 500, standard deviation 100). For Holsteins, the weights are 40% Production (PI), 32% Longevity & Type (LTI), 8% Health & Welfare (HWI), 10% Reproduction (RI), 5% Milkability (MI), and 5% Environmental Impact (EI) — confirmed in Van Doormaal et al.’s Interbull Bulletin paper (No. 61, June 2025), with economic values estimated by AbacusBio.

Here’s how the top-20 registration bulls score on the four subindexes outside production and type:

SubindexAvg Percentile RankRangeBulls Below 50th
Health & Welfare (HWI)47%7–94%13 of 20
Reproduction (RI)31%2–68%17 of 20
Milkability (MI)47%9–87%12 of 20
Environmental Impact (EI)33%1–73%15 of 20

These are group averages — individual bulls vary widely, as the ranges show. A few cleared the 50th percentile on every subindex. The concern is the pattern across the group, not any single sire.

But the pattern is stark. Bulls producing nearly a quarter of all registered Canadian Holsteins average the 31st percentile on reproduction. Fifteen of the twenty fall below the breed midpoint on environmental impact. On health and welfare, thirteen of the twenty sit below average.

The combined weight of HWI + RI + MI + EI inside LPI is only 28%. That’s enough to show up on a proof sheet — nowhere near enough to change a sire’s ranking when 72% of LPI comes from production and type. Van Doormaal et al. noted this tension directly: the Reproduction Index has the lowest correlation with overall LPI (0.39) among all six subindexes, “stemming from the underlying negative correlation between female fertility traits and other key traits in the LPI, especially milk yield and some key conformation traits.”

The system is built so that bulls can be elite on LPI while being middling on fertility. And the twenty most-used sires are proving it.

Fat and Type Are Strong — But Look at That Milk Range

The production and type averages reinforce why these bulls earned their registrations:

TraitAverage%RKRange
Milk+75 kg70%−419 to +2,053 kg
Fat+88 kg (+0.40%F)80%30–118 kg (−0.07 to +1.08%F)
Protein+58 kg (+0.21%P)77%9–93 kg (−0.01 to +0.53%P)
Conformation+9.794%+2 to +16
Mammary+5.881%−3 to +12
Feet & Legs+8.091%+4 to +15
Dairy Strength+8.692%+4 to +15
Rump+5.781%+1 to +13

Components are solid — +0.40%F and +0.21%P — which matters in every component-pricing province. Conformation at 94th percentile, Feet & Legs at 91st, Dairy Strength at 92nd. This is a type-forward group, exactly what you’d expect from bulls popular with breeders who register.

One number is lower than expected: Mammary at +5.8 and 81% RK. Mammary System carries 37% of the LTI subindex in the modernized formula, so you’d think the most-used bulls would rank higher. One bull in this group actually scores −3 on the Mammary trait. When a sire below average on udders still cracks the top-20 usage list, it tells you breeders are prioritizing other traits — components, caseins, polled status — enough to accept trade-offs they wouldn’t have a decade ago.

That milk range deserves a second look too: −419 to +2,053 kg. Some of these bulls are actively pulling volume down while pushing components up. That’s a deliberate bet on solids percentages over volume — smart if your processor rewards percentage, risky if they still pay primarily on litres.

What Happens When You Pull Your Own Tank’s Subindex Sheets?

Here’s where the subindex data shifts from abstract to personal: most producers using these bulls haven’t had easy access to this breakdown of their sire lineup — at least not in a format that puts the information front and center at decision time.

The Bullvine’s “No-Holes Sire” analysis (August 2025) drove this point home. Even among the highest-ranking LPI bulls in the breed, genuinely balanced profiles are rare. Apollo-PP — the highest-ranking homozygous polled sire with five of six subindexes above 50% RK — still falls to 41% on Reproduction. At 3,924 LPI and 99% RK on Longevity & Type, Apollo-PP is an outstanding bull. But if the best polled sire available in August 2025 still had a fertility hole, imagine what the average top-20 registration bull’s sheet looks like when you scan all six subindex columns.

That gap between what the data shows and what breeders actually see when choosing semen is the real story here. It all starts with complete information, but the rubber truly meets the road when milking daughters are performing on Canadian farms.

From 45% A2A2 to 70% in Two Years — The Casein Shift Is Real.

Across the top 20 in 2025:

Trait2021–20232025
A2A2 beta-casein45%70%
BB kappa-casein19%50%
Homozygous polled (PP)4%15%
  • A2A2 beta-casein: about 70%
  • BB kappa-casein: about 50%
  • Homozygous polled (PP): about 15%
  • Red carrier (RC): about 15%

These aren’t soft impressions. When The Bullvine analyzed the 2021–2023 registration data using Holstein Canada’s sire lists, the numbers looked very different: 45% of registrations came from A2A2 sires, 19% from BB kappa-casein sires, and just 4% from homozygous polled bulls. In two years, A2A2 representation among the top sires has jumped from 45% to roughly 70%. BB kappa-casein has gone from 19% to about 50%. Homozygous polled has nearly quadrupled — from 4% to approximately 15%.

A2P2, sitting at number one, and Right Stuff PP, at number eleven, are the headline acts. But even further down the list, casein and polled profiles are stacking. Breeders aren’t just checking the box on caseins anymore — they’re treating them as a primary selection criterion, driven partly by processor signaling on cheese yield and partly by consumer-facing A2 milk marketing.

The polled story is even more pointed. With 15% of the top-20 sires homozygous polled — up from 4% in the 2021–2023 window — the old argument that “there aren’t enough good polled bulls” doesn’t hold up against the registration data. If you’re still dehorning every calf in 2026, that’s a management choice, not a genetic constraint.

11.9% Average Inbreeding — and Only Three Below 10%

Here’s where the data shifts from uncomfortable to urgent.

Average inbreeding coefficient across the top 20 is 11.9%, with a range of 8.74% to 15.95%. Only three of the twenty sit below 10%.

For context: Lactanet’s August 2025 inbreeding update reported that the average inbreeding level for Canadian Holstein heifers born in 2024 reached 9.99%. On a pedigree basis, Holstein inbreeding has been increasing by approximately 0.25% per year since 2010, according to Lactanet’s annual reports authored by Brian Van Doormaal. That’s the breed average. These twenty bulls — the ones shaping nearly a quarter of the next generation — sit almost two full percentage points above it.

Penn State geneticist Dr. Chad Dechow has documented that current U.S. Holstein inbreeding averages around 8%, with young bulls running 9–10%. In the Netherlands, Doekes et al. (2019) at Wageningen University studied 38,792 first-parity Dutch Holstein-Friesians and found that a 1% increase in genomic inbreeding (FROH) was associated with a 36.3 kg decrease in 305-day milk yield, a 0.48-day increase in calving interval, and a 0.86-unit increase in somatic cell score. At the University of Parma, Ablondi et al. confirmed the pattern: their 2023 analysis of 27,735 Italian Holstein cows found every 1% increase in genomic inbreeding cut 305-day milk yield by approximately 61 kg and reduced both fat and protein yields (Journal of Animal Science, 101:1–10).

Virginia Tech research goes back further — and the numbers are bigger than most people assume. Smith, Cassell, and Pearson studied over 2.6 million lactation records from U.S. Holsteins (Journal of Dairy Science, 81:2729–2737, 1998). The all-cow results showed a loss of $12–$15 per 1% increase in inbreeding. But when Cassell drilled into the registered-cow subset — 257,449 animals with complete pedigree data, where true inbreeding levels are most accurately captured — the loss jumped to $22–$24 per 1%: $24 in a fluid market, $22 in a cheese market (1999 Western Canadian Dairy Seminar). Cassell advised placing “greater reliance on results from registered herds” because incomplete pedigrees in grade cows understate true inbreeding. Adjusted for inflation, the registered-cow figures come to roughly $40–$46 in today’s dollars.

Inbreeding Gap (% points above 9.5%)Cost per Cow (CAD, lifetime)Cost on 200-Cow Herd (CAD)Cost on 500-Cow Herd (CAD)
+1.0 percentage point$40–$46$8,000–$9,200$20,000–$23,000
+1.5 percentage points$60–$69$12,000–$13,800$30,000–$34,500
+2.0 percentage points$80–$92$16,000–$18,400$40,000–$46,000
+2.4 percentage points (top-20 avg)$96–$110$19,200–$22,000$48,000–$55,000
+3.0 percentage points$120–$138$24,000–$27,600$60,000–$69,000

One more finding from that WCDS paper worth noting: the losses were linear. The cost per percentage point at 12% was the same as at 3%. There’s no safe plateau — every additional point of inbreeding extracts the same toll.

What Does 11.9% Actually Cost at the Cow Level?

That 11.9% is the sires’ own inbreeding — a measure of their homozygosity, not a direct prediction of where their daughters will land. Daughter inbreeding depends on the dam side of every mating, too.

But in a breed already averaging 9.99%, using sires this inbred makes it nearly impossible to keep daughters below a 9.5% ceiling without deliberately seeking low-relationship dams. If daughters end up even 2 percentage points above a 9.5% target — a conservative estimate given these sire levels — the registered-cow figures suggest roughly $80–$92 per cow in lifetime profit drag, or $16,000–$18,400 on a 200-cow herd. Push that gap to 2.4 points, and the numbers run to $96–$110 per cow and $19,200–$22,000 per herd.

The exact cost depends on your mating program. As Cassell himself wrote in that 1999 WCDS paper: “There is no magic level of inbreeding that is acceptable.” But the direction is clear — and these are the bulls most herds are already using.

Can Breeders Actually See the Problem — Or Is It Buried?

Lactanet deserves credit for building the tools. The modernized LPI subindexes launched in April 2025. A detailed percentile-rank guide followed in June. And the Lactanet Inbreeding Calculator — which shows projected inbreeding levels and parent averages for any potential mating — has been one of the site’s most frequently used features for years.

Compass, the free genetic management software built by Holstein Canada and Lactanet (with Zoetis support), launched on November 14, 2019, lets producers create a customized version of LPI or Pro$ that matches their breeding goals, track genetic progress, and view return-on-investment projections. It’s an unbiased source — it doesn’t sell semen. Lactanet also offers a Personalized LPI (pLPI) through LactanetGen.ca — you set the subindex weights yourself to match your own priorities. A producer who wants more emphasis on health and reproduction can shift from the default 8% HWI / 10% RI to, say, 12% and 14%, and the system re-ranks every bull accordingly. The trade-off is real, though: those extra percentage points have to come from somewhere, typically Production or Longevity & Type, which means your pLPI rankings will look different from the semen catalog’s default LPI list — and that’s exactly the point.

Balance Threshold# of Top-20 Sires Meeting ThresholdWhat This Means
All 6 subindexes above 40% RK~8–10Marginal balance — still risky on 1–2 traits
All 6 subindexes above 50% RK~3–5True breed-average balance — rare even in elite sires
5 of 6 subindexes above 50% RK (1 weakness OK)~7–9“No-Holes Sire” standard — strategic weakness acceptable
HWI + RI both above 50% RK~3–4Health and fertility balance — where replacement costs are decided

So the tools exist. But scroll through the sire listings from major AI companies and the picture changes. EastGen’s online catalog lets you sort bulls by GLPI, Pro$, A2A2, Polled, and Robot Ready — but not by subindex rank for Health & Welfare or Reproduction. Semex’s SemexWorks™ builds custom client indexes with reps, which can incorporate more traits — but that requires a conversation the rep initiates. The default presentation in most catalogs still leads with LPI or Pro$ in large type. Subindex percentile ranks, if they appear at all, sit in the fine print.

That means the data Lactanet publishes and the data breeders see when they’re choosing semen are often two different things. Until AI catalogs give subindexes the same real estate as LPI and Pro$, producers who want that information are pulling it themselves — and, based on how those catalogs are structured, most aren’t.

That’s not an indictment of anyone. It’s a description of where the industry sits and where the opportunity is widest.

What This Means Before Your Next Semen Order

Every one of these findings connects to a decision you’re making this year.

This month: Pull Lactanet’s subindex breakdown for every sire currently in your tank. Flag any bull below 50% RK on three or more of HWI, RI, MI, and EI. That doesn’t mean you drop him — it means you know which cow groups he should and shouldn’t be matched with, and you’re not flying blind. The Bullvine’s “No-Holes Sire” analysisrecommends at least five of six subindexes above 50% RK as the threshold for a balanced sire. Even Apollo-PP — the highest-ranking August 2025 PP sire in the breed at 3,924 LPI — hits five of six but still falls to 41% RK on Reproduction. That should tell you how rare true balance is, and how intentional you need to be to get it.

Before your next order (within 90 days): Run inbreeding projections on planned matings using Lactanet’s Inbreeding Calculator and set an explicit ceiling. A target of 9.5% is a defensible starting point — already below where the 2024-born heifer average sits. One honest trade-off: in narrow pedigree pools, hitting that ceiling may force you toward lower-LPI sires. That’s a real cost. But a bull at 3,400 LPI with 9% inbreeding and solid health and fertility scores may deliver more lifetime profit than one at 3,800 LPI with 13% inbreeding. The LPI gap is smaller than the inbreeding depression gap. If you’re thinking about how to structure a complementary sire roster — balancing production, components, durability, and an outcross slot — that $869-per-cow lifetime profit gap between top-quartile and bottom-quartile genetics from the Zoetis study of 12,952 Holsteins makes the case for being deliberate.

By the April 2027 proof run: Audit the first-born 2025 calves from these top-20 sires in your herd. Track health events, conception rates, and SCC by sire group. Compare actual daughter performance against proof-sheet promises, especially for traits where these bulls scored below average. That’s your reality check — and the data you need to adjust for 2027 sire selection.

On caseins and polled: If your processor pays any component or A2 premium, use the 70% A2A2 baseline in this top-20 group as your floor, not your ceiling, with BB kappa-casein at 50% and PP at 15% — both up dramatically from 45% and 19%, respectively, just two years ago — you can build a casein-forward, polled herd without sacrificing competitive LPI. A2P2 and Right Stuff PP demonstrate that.

At the kitchen table with your AI rep: Ask where each bull ranks on all six Lactanet subindexes — not just LPI and Pro$. Ask about the projected inbreeding on the specific mating. Ask how many of their “recommended” sires sit above the breed midpoint for HWI and RI. If the answers are vague, you’ve learned something important about how that sire list was put together. And ask whether they’ve set you up in Compass and pLPI — both are free, both are unbiased, and both let you weight the traits that matter to your herd, not theirs.

Key Takeaways

  • If your working sire team is drawn heavily from this top-20 list, you’re getting elite production and type — but you’re likely below the breed midpoint on health, fertility, milking speed, and environmental impact without active subindex management.
  • At 11.9% sire inbreeding in a breed averaging 9.99%, the cost of genetic narrowing runs roughly $80–$110 per cow in lifetime profit drag, depending on mating patterns — using Virginia Tech registered-cow estimates adjusted for inflation. On a 200-cow herd, that’s $16,000–$22,000 that shows up in your replacement pipeline, not on any invoice.
  • The casein and polled shift is accelerating. A2A2 went from 45% to about 70% of top-use sires in two years; BB kappa-casein from 19% to about 50%; homozygous polled from 4% to about 15%.
  • Lactanet built the subindexes, standardized them, and published them with a June 2025 percentile-rank guide. Compass and pLPI are both free and unbiased. The gap isn’t in the data — it’s in how consistently AI catalogs and sales representatives’ conversations put that data in front of producers when they’re choosing bulls.

The Bottom Line

These twenty bulls are real. They bring strong LPI, solid components, high type, and casein profiles that Canadian breeders couldn’t access a decade ago. That’s genuine progress — and it shouldn’t be dismissed.

But the same proof sheets that make them dominant also expose a national breeding program tilted toward production and type at the expense of health, fertility, and genetic diversity. Lactanet gave breeders the subindex tools ten months ago. Whether the industry — AI companies, breed associations, and the producers writing the semen cheques — will use them before the next generation of heifers hits the milking string is the question that matters now.

Pull your subindex sheets this week. How many of your current sires clear 50% RK on all six subindexes?

The December Genetic Reckoning: Former Champions Fall, New Kings Rise – and Your 2026 Strategy Just Changed

Wednesday, December 3rd, 2025

December didn’t just reshuffle the rankings—it exposed who was betting on hype. Top bulls cratered overnight. New kings emerged. Your 2026 matings need a rewrite.

The December 2025 genetic evaluations weren’t just another routine update. They were a full-scale reset of global Holstein rankings—the kind that happens once every decade or so. From the powerhouses of North America to the diverse breeding programs of Europe and Scandinavia, the genetic pecking order has been violently reshuffled. Former leaders have been dethroned. Unexpected champions have been crowned. And for dairy breeders planning their 2026 mating programs, the message is stark: the genetic playbook from August is now obsolete.

This isn’t hyperbole. It’s a hard reality backed by the data. And if you’re still making breeding decisions based on last summer’s rankings, you’re leaving money on the table.

Three Seismic Shifts Defining the New Genetic Reality

The December evaluations revealed three interconnected forces reshaping global Holstein genetics:

  1. Unprecedented Volatility in Genomic Rankings
    Several high-profile sires—bulls that were industry darlings just weeks ago—have experienced dramatic, overnight index drops. In Switzerland, the former #1 sire, Sous-Moron Boston, suffered a stunning 52-point ISET collapse. In Italy, the polled star KNO Ecuador P plummeted an incredible 98 gPFT points. These aren’t statistical blips; they’re textbook examples of genomic risk materializing in real time.
  2. Genetic Concentration Consolidating Around Specific Bloodlines
    Genosource now controls 22 of the top 30 Net Merit positions in the US—a remarkable 73% market share. The Gameday maternal line underpins three of Switzerland’s top five ISET sires. The Altazazzle bloodline claims four of the top ten proven sire positions in the Netherlands. This concentration delivers elite, consistent results—but it also creates a ticking time bomb for inbreeding and genetic diversity.
  3. Components Are No Longer Optional
    From Canada’s BEYOND HI-LEVEL-ET (165 kg Fat) to Germany’s Saturn RDC (+0.88% Fat), the message is universal: with processor payments increasingly tied to milk solids, selecting for high fat and protein is now a direct path to a higher milk check. The days of overlooking component specialists are over.

North America: Where Profit and Components Rule

The North American market continues to set the global pace for Holstein genetics. But the December evaluations revealed two distinct narratives unfolding on opposite sides of the border.

Canada: The Component King Has Arrived

OCD MILAN-ET held his ground as the #1 LPI sire with a solid 19-point gain to 4137 LPI, but the real story belongs to his challengers—three newcomers who have rewritten the options for breeders.

BEYOND HI-LEVEL-ET made the most explosive leap, jumping 11 spots to #4 LPI. His profile reads like a case study in modern profitability: 165 kg Fat on a high-volume base that proves elite milk volume and exceptional component density aren’t mutually exclusive. For breeders paid on component density, he’s become the gold standard.

Then there’s BEYOND HOORAY-ET, who debuted at #3 LPI and immediately established himself as the “percentage specialist.” With +1.10% Fat and +0.52% Protein, his profile is tailor-made for herds targeting premium milk quality.

Perhaps most significant: PROGENESIS SHEAMUS-P shattered the ceiling for polled genetics, debuting at #2 LPI. He’s the highest-ranking polled genomic sire in Canadian history—proof that breeders no longer have to sacrifice elite index performance to access the valuable polled trait.

USA: The Genosource Era Begins

If Canada’s story is about newcomer diversity, the US narrative is about unprecedented consolidation.

Genosource has achieved a historic sweep, capturing 22 of the top 30 Net Merit positions. For context: this represents a 73% market share in the industry’s primary profitability index. That level of concentration is a double-edged sword. On one hand, it offers a clear path to proven, high-profit genetics backed by a program that has cracked the code on profitability. On the other hand, it severely narrows the available gene pool—and that’s a serious concern for long-term herd resilience.

GENOSOURCE RETROSPECT-ET continues his reign as the #1 NM bull at 1296, demonstrating the program’s mastery of the total economic merit formula. But the most explosive newcomer was SAN-DAN ON CALL-ET, who debuted at #3 GTPI with a production profile that demands attention: 1845 Milk and 151 Fat. The fact that he also earned a #9 NM ranking tells you his balanced genetics appeal across multiple profit drivers.

And confirming the component trend: BEYOND HI-LEVEL-ET claimed the #1 GTPI position in the US at 3612, underscoring his international elite status.

Europe: Bloodlines, Balance, and the Rise of Functional Genetics

Europe’s evaluations revealed a shared philosophy: rewarding balanced, functional cattle designed to thrive in real-world commercial systems. While each country maintains its own index, a common theme emerged in the dominance of bloodlines that consistently deliver both profitability and longevity.

United Kingdom: Sheepster’s Legacy Reshapes the Breed

The new #1 genomic sire is DENOVO COYOTE P, with a PLI of £871. His profile is textbook modern British dairy: exceptional +0.30% fat, commercially valuable A2A2 status, and polled genetics.

But the more significant story belongs to OCD TROOPER SHEEPSTER, who graduated to #1 on the daughter-proven side with a £783 PLI. His true significance extends far beyond his own rank—he’s become a breed-shaping sire of sons. Multiple Sheepster offspring, including BADGER SIEMERS DAY TRIP (#2 genomic) and PROGENESIS PRESTON (#3 genomic), now dominate the young sire lists. This is the kind of bloodline dominance that builds lasting competitive advantage.

Netherlands: Shattering the +400 Barrier

Genosource Moti rewrote the Dutch record books, becoming the first sire to lead the genomic rankings at a remarkable +420 NVI. This isn’t just a personal achievement—it signals that the ceiling for genetic progress continues to rise.

What’s truly revealing, however, is the absolute conquest of the Altazazzle bloodline in the proven rankings. This line claims four of the top ten positions—a clear market vote for what commercial dairies crave: the “invisible cow.” Moderate. Functional. Invisible until you look at the milk check. Their dominance validates a breeding philosophy that prioritizes trouble-free performance over extreme individual traits.

Germany: New Champions in Both Populations

For Black & White genomic sires, newcomer Saturn RDC tied for the top with the former leader, Veterano, at 164 RZG. Saturn RDC immediately distinguished himself with a massive +0.88% Fat—the component specialist phenotype that the market is rewarding globally.

The new Red & White genomic leader is Bueno Red at 161 RZG. He offers a rare combination: extreme milk production (+2,159 kg) paired with excellent type (121 RZE). This kind of balanced profile is increasingly valuable as European breeders recognize that extremes in single traits often create hidden costs elsewhere.

The Volatility Report: When Genomic Promise Meets Reality

While some markets celebrated steady progress, Switzerland, Italy, and Scandinavia delivered a masterclass in genomic risk. In these countries, several reigning #1 sires experienced dramatic overnight index drops—a powerful reminder of why risk management matters in breeding programs.

Switzerland & Italy: The Reckoning for Unproven Genetics

In Switzerland, Sous-Moron Boston’s 52-point ISET drop (from +1645 to +1593) wasn’t an anomaly—it was the statistical consequence of reliability risk. Here’s the hard truth: a 75% reliable genomic proof means there’s a 25% chance the bull’s true genetic merit will differ significantly from his initial ranking. For Boston, that risk materialized in index drops that erased millions in projected genetic value overnight.

Italy’s story was even more dramatic. The high-profile polled star KNO Ecuador P plummeted 98 gPFT points as more daughter data recalibrated his initial genomic promise. This is what happens when market enthusiasm outpaces actual proof of reliability.

With the deck reshuffled, Italy’s new international genomic leader is DENOVO LOCUST-ET, with a formidable gPFT of 5450.

Scandinavia: The Nordic Shakeup

The Nordic Total Merit (NTM) index experienced its own dramatic power struggle. The former genomic leader, Fly P, experienced a precipitous 8-point drop from +49 NTM to +41 NTM—one of the sharpest single-round declines on record for a top bull.

His fall coincided with the spectacular debut of VH Sheriff, who entered the rankings at an exceptional +51 NTM. This contrast illustrates a critical principle: high-potential genomic projections and high-certainty proven results often tell different stories. On the proven sire list, PEAK RAINOW-ET held his position as the reliable leader at +42 NTM, providing a crucial stability anchor.

Four Strategic Imperatives for Your 2026 Breeding Program

The December 2025 proofs delivered clear signals. Here’s how to act on them:

1. Embrace Volatility—and Manage It

The dramatic index drops of bulls like Boston, Ecuador P, and Fly P are the most important risk management lesson of this evaluation cycle. A chart-topping genomic proof is a powerful indicator of potential, but it’s not a guarantee of performance.

Action: Diversify your sire portfolio ruthlessly. Don’t concentrate more than 15-20% of your herd’s matings on any single unproven genomic bull, no matter how impressive his initial ranking. A team of high-quality young sires will always outperform a single superstar who fails to deliver.

2. Follow the Money: Components Drive the Milk Check

From Canada’s component specialists to Germany’s fat-specialists and Switzerland’s balanced bulls, the message is universal. Processor payments increasingly tie to milk solids. Component selection isn’t a nice-to-have anymore—it’s the direct path to higher revenue.

Action: Prioritize sires transmitting high kilograms AND high percentages of fat and protein. These specialists are your best tool for maximizing revenue per hundredweight.

3. Mind the Inbreeding Gap

The genetic concentration around Genosource in the US, the Gameday line in Switzerland, and the Altazazzle line in the Netherlands is a double-edged sword. Yes, these lines deliver elite results. But their dominance increases inbreeding risk in the broader population.

Action: Use mating programs to monitor and manage inbreeding coefficients. Protecting genetic diversity isn’t peripheral—it’s foundational for maintaining fertility, calf vigor, and long-term herd resilience. Be aware of the popular bloodlines and actively seek outcross options to balance your portfolio.

4. Proven Sires Remain Your Foundation

In an era of genomic volatility, the stability of high-reliability, daughter-proven sires is more valuable than ever. Leaders like OCD TROOPER SHEEPSTER in the UK and PEAK RAINOW-ET in Scandinavia provide the kind of anchor every breeding program needs.

Action: Allocate a meaningful portion of your matings to elite proven sires. Use them as a dependable risk-management tool to balance the high potential—but higher risk—of your genomic sire team. They’re not old news; they’re insurance against genomic volatility.

The Bottom Line

The December 2025 evaluations proved that Holstein genetics continues to evolve at a breathtaking pace. The ceiling for genetic progress keeps rising. New champions emerge. Old certainties crumble.

But here’s what shouldn’t change in your breeding strategy: disciplined risk management, relentless focus on the traits that drive profitability, and a balanced portfolio that combines proven reliability with genomic potential. The breeders who master this balance in 2026 will be the ones posting the highest milk checks and building the most resilient herds.

The genetic landscape has been reset. Now it’s time to update your playbook.

KEY TAKEAWAYS: 

  • Genomic promises just met reality: Switzerland’s #1 cratered 52 points. Italy’s polled star dropped 98. December proved that a 75% reliable proof carries 25% real risk—and millions in value can vanish overnight.
  • Components drive the milk check now: Fat and protein specialists dominated from Canada to Germany. Breeders ignoring solids aren’t just behind—they’re bleeding revenue.
  • Genosource owns 73% of America’s profit elite: Unprecedented consolidation delivers proven results, but shrinks the gene pool. Opportunity and inbreeding risk now travel together.
  • Diversify or pay the price: Cap any unproven genomic sire at 15-20% of matings. A balanced sire team always beats a single superstar who crashes.
  • Proven sires are your volatility hedge: Daughter-proven leaders like Sheepster and Peak Rainow deliver what genomic projections can’t—certainty.

EXECUTIVE SUMMARY: 

December’s reckoning separated the breeders who understand genomic risk from those who were chasing leaderboard hype. The bulls that cratered aren’t coming back. The bloodlines consolidating power aren’t slowing down. And the component premiums reshaping milk checks aren’t temporary. The question isn’t whether the genetic landscape has changed—it’s whether your breeding program has changed with it. August’s playbook is dead. What’s your 2026 strategy?

Genosource Moti Cracks +420 NVI: Inside the December 2025 Dutch Sire Shakeup

Wednesday, December 3rd, 2025

+420 NVI. A longevity score of +1,295. Altazazzle bloodlines dominating proven sires. The Dutch December 2025 rankings just raised the bar—here’s who’s setting it.

Executive Summary: The +400 NVI barrier hasn’t just been broken; it’s been shattered. Genosource Moti leads the charge at +420 NVI—a benchmark that redefines what’s achievable through genomic selection. Joining him in the top 10 are stablemates Mystro (posting the evaluation’s highest INET at +799) and Benson, whose +1,295 longevity score stands alone in this release. Among proven sires, Badger Ssi Ahead Jaffa tops the list at +358 NVI, while Altazazzle sons claim four of the top 10 spots—a concentration that underscores both the line’s commercial dominance and the breed’s narrowing genetic base. What sets this evaluation apart is balance: elite NVI bulls are simultaneously delivering on longevity, udder health, and fertility, breaking the historic trade-off between production and functionality. The Genosource and Delta programs command the genomic tier; Altazazzle defines the proven ranks. For breeders, this release offers exceptional genetic tools—with the caveat that pedigree concentration at the top makes diversity management more critical than ever.

Dutch sire rankings 2025

There’s something particularly exciting about cracking open a new proof run. The December 2025 Dutch genetic evaluation landed with some eye-catching numbers—and a few surprises worth talking through. For breeders working with Dutch and Flemish genetics, this release offers a snapshot of where the breed is heading, and honestly, the trajectory is impressive.

The NVI (Nederlands-Vlaamse Index) continues to do what it was designed to do: identify bulls capable of producing daughters that are profitable, durable, and trouble-free. It’s a total merit index that balances production with the functional traits that actually keep cows in the herd—things like udder health, fertility, and feet and legs. What I’ve noticed over the past several proof runs is how the top end of these rankings keeps climbing. We’re seeing NVI values now that would have been almost unthinkable five years ago.

Let’s dig into what this release is showing us.

The Genomic Leaders: A New Benchmark

The genomic sire rankings this round are nothing short of remarkable. We’ve crossed a threshold here that deserves attention.

Genosource Moti sits atop the list at +420 NVI—a number that genuinely made me do a double-take when I first saw it. This Matcrest Arc son out of a Stgen Cowen Tho dam combines serious production punch (+2,025 kg Milk, +130 kg Fat, +68 kg Protein) with functional longevity (+872 days). His INET of +682 signals that daughters should convert feed to profit at an elite level. At 66% reliability, he’s still a genomic prospect, but the genetic package is hard to ignore.

What’s interesting about the top of this list is the diversity of pathways to elite NVI. Halifax Delta Dawn (+414 NVI), a Hammerhead son, takes a slightly different route—he posts the highest INET among the top five genomics at +737, driven by exceptional component transmission (+138 kg Fat, +75 kg Protein). His +2,220 kg Milk puts him among the highest-volume transmitters in the evaluation.

Rise Up Real (+410 NVI) caught my attention for a different reason entirely. This Real Syn son stands out as a longevity specialist, posting +1,019 days—the highest among the top five genomic bulls. For herds where keeping cows productive across multiple lactations is a priority, that’s a significant number. His +2,422 kg Milk shows you don’t have to sacrifice production to get durability.

What the Pedigrees Are Telling Us

If you scan down that top-10 list, a few patterns jump out. The Genosource program has clearly hit its stride—three bulls in the top ten (Moti, Mystro, and Benson), all built on either Matcrest Arc or Radical foundations. That’s not an accident. These pedigrees have been stacked for production efficiency, and it’s showing up in the rankings.

The Delta breeding program from CRV is equally impressive, placing Miller, Time Jump, and Standout in the upper tier. What I find notable here is the consistency—these aren’t one-hit wonders but rather the product of a coherent breeding philosophy emphasizing balanced improvement.

The Real Syn sire line deserves special mention. He appears as the sire of Rise Up Real (#3), and his influence extends throughout the evaluation. This line seems to offer a particular combination of high milk volume with above-average longevity—a balance that’s historically been tricky to achieve.

Now, here’s where I’d offer a word of caution. The genetic engine is running hot, but it’s running narrow. When you see this much concentration of specific bloodlines at the top of the rankings, it’s worth thinking carefully about genetic diversity in your own herd. These sires offer tremendous genetic potential, but smart breeders need to use these tools strategically—or risk painting themselves into a pedigree corner. Monitor inbreeding levels and maintain enough diversity to keep your herd genetically resilient for the long haul.

The Proven Sires: Where Reliability Meets Results

Genomic sires represent what’s possible. Daughter-proven bulls show us what’s been delivered. For breeders who prioritize predictability—and there are good reasons to do so—the proven sire rankings provide a different kind of value.

Badger Ssi Ahead Jaffa leads the proven list at +358 NVI. This Ahead son from an A-S-Cannon Frzz dam has built his proof on genuine daughter performance, and the numbers are compelling. His +629 INET paired with +846 days longevity demonstrates that elite profitability doesn’t have to come at the expense of durability. The component transmission is solid (+102 kg Fat, +75 kg Protein), and his daughters are showing up well for udder health (107) and frame (106).

What farmers are finding with bulls like this is consistency. When you use a proven sire with high reliability, you know what you’re getting. There’s real value in that predictability, especially for operations where managing variance matters.

Peak Altazemini (+321 NVI) represents the continued strength of the Altazazzle bloodline. This Peak Genetics bull combines +592 INET with solid component transmission (+104 kg Fat, +65 kg Protein). His daughters are proving up well for both production and type.

Kax Gladius Gazebo (+320 NVI) takes a different approach—he’s the volume specialist in this group. At +2,745 kg Milk, he posts the highest production of any proven sire in the top ranks. For herds in fluid milk markets or operations pushing for maximum throughput, that kind of volume transmission is attractive. His Superhero maternal grandsire contributes proven durability genetics.

The Altazazzle Story

Looking at the proven sire rankings, the story isn’t just about who is number one—it’s about who owns the board. Altazazzle bloodlines claim four of the top ten spots (Peak Altazemini, Peak Breaking News, Peak Altazingler, and Peak Fugleman). That isn’t just influence; it’s a takeover.

The market has spoken: this line delivers the “invisible cow” commercial dairies crave—moderate, functional, and invisible until you look at the milk check. Altazazzle daughters aren’t extreme in any one direction, but they’re consistently profitable. They show up, milk, breed back, and don’t create problems. In commercial operations where trouble-free cows drive the bottom line, that consistency has real value.

The Finder bloodline also continues to show well through Delta Reloader (#8), who posts +701 days longevity backed by 95% reliability. That’s a substantial proof—the kind of daughter base that gives you real confidence in the numbers.

A Note on the Red & White Rankings

This article focuses on the Black & White (Zwartbont) evaluation, but it’s worth noting that the Red & White rankings delivered their own headline: Delta Richman PP-Red leads the R&W genomic sires at +414 NVI—a remarkable figure that would have topped the B&W list just a few proof runs ago. We’ll cover the R&W evaluation in detail separately, but breeders working with red genetics should take note: the color line is producing elite genetics of its own.

Trait Leaders: Bulls for Specific Breeding Goals

Sometimes the best bull for your herd isn’t the one at the top of the overall ranking. It’s the one that fixes your specific problem or pushes your herd in a particular direction. Here’s where looking beyond NVI becomes valuable.

For Maximum Component Value

If butterfat and protein payments drive your milk check—and they do for most producers these days—these bulls deserve attention:

  • Genosource Mystro (Matcrest Arc): INET +799, +146 kg Fat, +84 kg Protein
  • Halifax Delta Dawn (Hammerhead): INET +737, +138 kg Fat, +75 kg Protein
  • Delta Miller (Altamuller): INET +692, +119 kg Fat, +78 kg Protein

Mystro, in particular, posts the highest INET in the entire genomic evaluation. For herds focused on maximizing revenue per hundredweight in component-driven markets, he’s worth serious consideration.

For Herd Life and Trouble-Free Cows

Some operations prioritize keeping cows in the herd. Replacement costs, the learning curve for first-lactation animals, the value of mature cows hitting their production stride—there are solid economic arguments for breeding bulls that transmit longevity. These genomic sires excel in that department:

  • Genosource Benson (Radical): Longevity +1,295 days, Udder Health 100, Fertility 100
  • Delta Miller (Altamuller): Longevity +1,032 days, Udder Health 106, Fertility 105
  • Rise Up Real (Real Syn): Longevity +1,019 days, Udder Health 105, Fertility 104

Benson’s +1,295 longevity figure stands out—it’s the highest among any bull in the top genomic ranks. His daughters should be the kind that stick around, lactation after lactation.

For Functional Conformation

In modern free-stall facilities, cows need to move well and have udders that hold up to the demands of robotic or parlor milking. Functional type isn’t about winning shows—it’s about keeping cows productive and comfortable. Among the proven sires:

  • Peak Altazingler Et (Altazazzle): Udder 100, Feet & Legs 91, Frame 108
  • Peak Breaking News (Altazazzle): Udder 106, Feet & Legs 91, Frame 108
  • Delta Reloader (Finder): Udder 103, Feet & Legs 103, Frame 110

Delta Reloader’s combination of strong udders and excellent feet and legs makes him particularly valuable for herds where cow mobility and udder durability are concerns.

Putting It Together: What This Means for Your Breeding Program

The December 2025 Dutch evaluation confirms several trends that have been building over recent proof runs. The genetic level at the top continues to climb—NVI values above +400 are now a reality in the genomic ranks. The balance between production and functionality seems to be improving, with several bulls combining high INET with strong longevity figures.

Here’s how I’d think about using this information:

Consider a tiered approach. Use high-NVI genomic sires like Genosource Moti or Halifax Delta Dawn on a portion of your herd—perhaps your best cows or heifers—to capture the latest genetic progress. At the same time, lean on high-reliability proven sires like Badger Ssi Ahead Jaffa for core breeding decisions where predictability matters most. This balances potential against certainty.

Use trait leaders for corrective mating. That’s what they’re there for. If you’ve got a family with udder depth concerns, reach for a bull like Delta Reloader. If fertility has been an issue, look at bulls with strong VRU scores. The overall NVI matters, but the breakdowns of individual traits matter too.

Watch your pedigree concentrations. I mentioned this earlier, but it bears repeating. With Altazazzle so heavily represented in the proven ranks and Matcrest Arc/Radical dominant in the genomics, it would be easy to stack these bloodlines inadvertently. Monitor your inbreeding levels and maintain enough diversity to keep your herd genetically resilient.

Think about your market. A high-volume bull like Kax Gladius Gazebo (+2,745 kg Milk) makes sense in certain situations—fluid milk contracts, high-throughput operations, markets where volume still drives revenue. But if you’re selling milk on components, the math might favor a bull like Genosource Mystro with his exceptional fat and protein transmission.

The Bottom Line

The Dutch genetic evaluation continues to produce bulls capable of meaningful genetic progress. What strikes me about this December 2025 release is the overall quality at the top—whether you’re looking at genomic prospects or proven sires, multiple options combine elite production potential with the functional traits that keep daughters profitable over time.

The work happening in Dutch and Flemish breeding programs is clearly paying dividends. For breeders worldwide who access these genetics, the opportunity exists to tap into some of the best Holstein genetics available.

As always, the key is matching the right genetics to your specific operation, your market, and your goals. These rankings are a tool—a useful one—but the real work happens when you apply them thoughtfully to your own breeding decisions.

KEY TAKEAWAYS

  • Genomic selection crosses +420 NVI: Genosource Moti’s December 2025 ranking isn’t incremental—it marks a new threshold in genetic potential that will reshape sire selection benchmarks globally
  • Proven genetics deliver when predictability matters: Badger Ssi Ahead Jaffa leads at +358 NVI, combining +629 INET with +846 longevity at high reliability; for core breeding decisions, daughter-proven sires remain indispensable
  • Altazazzle commands the proven ranks: Four sons in the top 10 proven sires—this bloodline continues to define what commercial profitability looks like in today’s markets
  • The production-longevity trade-off is breaking down: Genosource Benson pairs +1,295 longevity with +656 INET; elite genetics now deliver cows that stay in the herd AND fill the tank
  • Diversity management becomes a competitive advantage: With Genosource, Delta, and Altazazzle dominating both genomic and proven tiers, herds that strategically maintain pedigree breadth position themselves for long-term resilience

December 2025 UK Holstein Genetic Evaluations: Sheepster Claims Proven Crown, Homegrown Coyote P Debuts at Genomic #1

Wednesday, December 3rd, 2025

The December 2025 UK proofs just dropped. New #1s in both rankings—and one sire’s bloodline is taking over the breed.

Executive Summary: The December 2025 UK Holstein genetic evaluations bring fresh leaders to both the genomic and daughter-proven rankings. UK-bred DENOVO COYOTE P debuts at genomic #1 with a PLI of £871, transmitting exceptional butterfat (+0.30%) and carrying both A2A2 and polled genetics—traits increasingly valued by processors and progressive herds alike. On the proven list, OCD TROOPER SHEEPSTER graduates to the top spot at £783 PLI, his daughters delivering +110 days lifespan and validating what his genomic figures promised years ago. Sheepster’s influence doesn’t stop there: multiple of his sons now rank among the genomic top 10, signalling a bloodline shaping the breed’s future. Across both rankings, the emphasis on feed efficiency, health traits, and milk components reflects an industry building cattle that perform profitably under real-world UK conditions. For producers weighing their next breeding decisions, this proof run offers genuine genetic depth—whether the priority is longevity, fertility, udder health, or butterfat.

The December 2025 genetic evaluations bring fresh faces to the top of both the young genomic and daughter-proven UK Holstein rankings. It’s a meaningful shift—and one that tells us quite a bit about where British dairy breeding is heading.

Looking at the bigger picture here, the trends are pretty clear. There’s a genuine push toward more efficient, easier-keeping cattle. Breeders are rewarding bulls that transmit strong butterfat percentages, solid health traits, and longevity. The industry’s focus on profitability per cow rather than just raw production continues to shape these rankings in practical ways.

The New Genomic Leader: DENOVO COYOTE P

The UK-bred DENOVO COYOTE P makes his debut at the very top of the young sire rankings with a Profitable Lifetime Index (£PLI) of £871 (AHDB December 2025 Genetic Evaluation). What’s interesting about this Winstar Klassic P son is how he balances production with health—he’s transmitting a fat percentage of +0.30% alongside respectable milk volume of 859 kg (AHDB December 2025 Genetic Evaluation).

That fat percentage figure is worth pausing on. UK processors have been signaling for years that they want more components, and bulls like Coyote P deliver exactly that. He’s also polled (POC) and carries A2A2 beta-casein status, which adds market flexibility for producers targeting specialty milk contracts.

Breaking Down the Genomic Top 10

The depth at the top of the genomic list this December is genuinely impressive. Here’s what stands out about each of the top performers:

  • #2 BADGER SIEMERS DAY TRIP (PLI £870): This Sheepster son brings outstanding daughter lifespan (+180 days) and excellent udder health with SCC of -20. For farmers focused on keeping cows in the herd longer, he’s worth serious consideration.
  • #3 PROGENESIS PRESTON (PLI £867 Another Sheepster son, Preston transmits strong protein (+0.10%) on solid milk volume of 978 kg. His mammary traits are respectable too.

A New Champion on the Proven List: OCD TROOPER SHEEPSTER

Turning to the daughter-proven rankings, OCD TROOPER SHEEPSTER graduates to the top spot with a PLI of £783 and reliability of 77% (AHDB December 2025 Genetic Evaluation). His daughters are living up to the promise his genomic figures made years ago.

What’s particularly noteworthy here is Sheepster’s influence on the breed. He’s now the sire of multiple bulls in the genomic top 10—including Badger Siemers Day Trip and Progenesis Preston. That kind of sire-of-sons success tells you his genetics are genuinely transmitting, not just testing well on paper.

His daughters show a lifespan advantage of +110 days, +0.17% fat, and +0.07% protein (AHDB December 2025 Genetic Evaluation). For producers looking for proven reliability backed by actual parlour performance, Sheepster delivers exactly that.

The Proven Top 10: Reliability Meets Performance

Understanding the Ranking Shifts

If you’ve been following these evaluations closely, you’ll notice some names have moved around. That’s normal—and actually reassuring. As more daughter data comes in, proof reliability increases, and PLI values adjust accordingly.

Genosource Captain, for instance, held the #1 proven spot in earlier evaluations but now sits at #7. That’s not because he’s become a worse bull—it’s because his proof has matured to 98% reliability, giving us a more accurate picture of his true genetic merit. The same pattern applies to Plain-Knoll Renegad Trooper’s movement from #2 to #5.

These fluctuations are exactly what we should expect from a well-functioning evaluation system. Early genomic predictions aren’t meant to be perfect—they’re meant to identify promising genetics faster than traditional progeny testing alone could manage.

Type Merit: New Leaders Emerge

For breeders who prioritize functional conformation alongside economic traits, the Type Merit rankings also saw changes this December.

Top Proven Type Sire: SANDY-VALLEY ESQUIRE now leads the daughter-proven list with a Type Merit of 3.02. He combines that conformation strength with reasonable production at 1,029 kg milk, though his fat percentage is negative at -0.26% (AHDB December 2025 Genetic Evaluation).

Top Genomic Type Sire: SYNERGY KICKSTART debuts at #1 for genomic Type Merit at 2.93. His PLI of £489 is lower than that of the PLI leaders, illustrating the trade-offs breeders face when prioritizing type over total economic merit (AHDB December 2025 Genetic Evaluation).

These bulls offer solid options for producers focused on physical structure—whether for show-ring goals or simply for building more durable, functional cattle.

The Bottom Line

The December 2025 rankings reinforce several practical takeaways for breeding decisions:

Component emphasis continues: Bulls transmitting positive fat percentages are increasingly rewarded in £PLI calculations. For producers under component-based contracts, this alignment makes genetic selection easier.

Longevity matters more than ever: Multiple top bulls in both rankings excel for lifespan traits. With replacement costs running high across UK dairy operations, keeping productive cows in the herd longer has a direct impact on the bottom line.

Sheepster’s influence is real: His sons now dominate the genomic rankings, suggesting that his genetics are consistently transmitted. That’s valuable information when evaluating lineage depth.

Genomic selection delivers: The smooth graduation of bulls like Powerhouse, T Rex, and Solace from genomic promise to proven performance validates the system’s predictive accuracy.

Whether you’re running a 100-cow family operation in Wales or managing a 500-cow unit in the East Midlands, these rankings offer genuine genetic tools for building more resilient, profitable herds. The key is matching sire selection to your specific goals—be that maximum components, longevity, fertility, or balanced improvement across traits.

Key Takeaways 

  • Homegrown bull takes genomic #1: UK-bred DENOVO COYOTE P debuts at the top (PLI £871) with exceptional butterfat (+0.30%) plus A2A2 and polled status—genetics that tick multiple boxes for forward-thinking herds
  • Sheepster graduates to proven leader: OCD TROOPER SHEEPSTER claims the proven crown (PLI £783) with daughters living 110 days longer than average—his early genomic promise now confirmed in the parlour
  • One sire’s bloodline is shaping the future: Multiple Sheepster sons—including Day Trip (#2) and Preston (#3)—rank in the genomic top 10, an uncommon depth of influence at the breed’s cutting edge
  • Butterfat drives PLI success: Bulls transmitting high fat percentages dominate both rankings—welcome alignment for producers on component-based contracts
  • Ranking shifts reflect better data, not worse bulls: Former leader Genosource Captain moved to #7 as his reliability hit 98%—that’s the evaluation system working exactly as designed

Italy’s New #1: DENOVO LOCUST Rises as ECBERT Falls 40 Points in December’s Genomic Rankings

Wednesday, December 3rd, 2025

LOCUST claims #1. ECBERT drops 40 points. ECUADOR crashes 98. December’s Italian rankings just reshuffled the deck.

Executive Summary: DENOVO LOCUST-ET seized Italy’s #1 international genomic ranking in December 2025, posting gPFT 5450 with +1,472 kg milk, +115 kg fat (+0.57%), and +96 kg protein. Domestic leader ECBERT retained his crown but dropped 40 points to gPFT 5349, while PINETA IRONGEN RASCASSE surged 42 points to become December’s top domestic mover. The proven sector delivered the cycle’s biggest story: The high-profile polled star KNO ECUADOR P plunged 98 points as daughter data corrected earlier projections, while ZFZ CRISALIS RF held firm at the top with gPFT 5180. Four international newcomers—HARMONY, SCOTTY, DREAMER, and THUMPING—broke the 5300 barrier. Eight Italian bulls debuted above gPFT 5070, signaling that domestic genetics are closing the gap. December’s lesson: the sires you banked on in August deserve a fresh evaluation today.

Italian Holstein gPFT rankings

December’s evaluation crowned a new international leader—and exposed cracks in former favorites. DENOVO 23392 LOCUST-ET (Sire: LODI; MGS: CASCADE) claimed the number one position with a commanding gPFT of 5450, edging out previous contenders with exceptional production credentials: +1,472 kg Milk, +115 kg Fat (0.57%), and +96 kg Protein (0.40%).

Hot on his heels, PEAK VINDICATE-ET and PEAK SPELLBOUND-ET sit virtually tied at gPFT 5445, making the top three positions a photo finish separated by just five index points.

Fresh International Genetics Breaking Through

Several high-powered international sires made notable December debuts above the 5300 gPFT threshold :

  • KENYON-HILL OC-ET HARMONY (Harmony x Gameday) – gPFT 5386
  • ADAWAY SUNDANCE SCOTTY-ET  (Sundance x Hayk) – gPFT 5374
  • KINGS-RANSOM O DREAMER-ET  (Owen x Happen) – gPFT 5348
  • PROGENESIS THUMPING (Hipster x Frost Bite) – gPFT 5318

Domestic Drama: ECBERT Holds Top Spot Despite 40-Point Drop

Italy’s homegrown genomic leader ECBERT (Sire: GLADIUS; MGS: DATELINE) maintained his domestic crown but couldn’t avoid a 40-point index decline, falling from 5389 to 5349 gPFT. Meanwhile, PINETA IRONGEN RASCASSE ET surged upward with a +42 point gain to secure second position at gPFT 5321—the evaluation’s biggest domestic mover.

BELLAVISTA PEACE5131CRISTELLA NAZARIO ET5077

Proven Sector: Stability at Top, Volatility Below

The daughter-proven rankings tell a more cautious story. ZFZ CRISALIS RF held firm as Italy’s top proven bull, ticking up slightly from 5169 to 5180 gPFT with a strong fat percentage (+0.16%). IDEVRA ROYAL INSEME CARLOMAGNO secured second place at gPFT 5068, delivering impressive milk volume (+1,568 kg) and solid longevity (105).

The proven sector’s headline loss: KNO ECUADOR P plummeted 98 points—from 4943 to 4845 gPFT—as additional daughter data recalibrated expectations. Conversely, ISOLABELLA DISTEFANO ET climbed 34 points to 4982 gPFT.

The Bottom Line

For breeders finalizing 2026 matings, December’s volatility demands one response: reassess before you commit. LOCUST’s emergence and ECBERT’s decline demonstrate why continuous index monitoring matters more than ever. For breeders targeting the Italian market, December’s evaluation reinforces that international genetics continue to set the pace—but domestic programs are closing the gap fast.

Data Source: ANAFIBJ December 2025 Italian Holstein Genetic Evaluations

Key Takeaways:

  •  LOCUST seizes #1: DENOVO LOCUST-ET tops Italy’s international genomics at gPFT 5450 with +1,472 kg milk, +115 kg fat, and +96 kg protein
  • ECBERT drops 40 points: Domestic leader holds #1 but bleeds index value while PINETA IRONGEN RASCASSE surges 42 points behind him
  • ECUADOR plunges 98 points: December’s proven-sector collapse proves daughter data can shatter genomic confidence overnight
  • 12 new elite sires debut: Four international bulls cracked gPFT 5300; eight Italian bulls entered above 5070—fresh firepower for 2026 matings
  • Your August picks need a December review: Index swings this size reward breeders who adapt, not those married to last cycle’s rankings

  • OCD MILAN-ET: 109 SCS
  • OCD MANNY-ET: 110 SCS
  • SYNERGY KICKSTART-ET: 100 SCS (breed average)

Herd Life Leaders:

  • PROGENESIS LEONIDAS: HL=12
  • OCD MANGO-ET: HL=10

Rumen Health Considerations: Bulls like OCD MANGO-ET (RP=13) and PROGENESIS LEONIDAS (RP=10) show strong positive RP scores. However, several high-LPI bulls carry negative RP scores—T-SPRUCE SUNSET-ET (RP=-11) and SIEMERS SSI SUN MEERKAT-ET (RP=-12)—requiring careful mating decisions.

Conformation Shakeup: Progenesis Takes the Type Throne

The conformation rankings saw dramatic movement as PROGENESIS AKSEL debuts at #1 with 20 Conf, dethroning August’s leader WALNUTLAWN PG BRIGHTSTAR.

Top Conformation Bulls (16+ Conf):

For breeders prioritizing feet and legs, BLONDIN LYNX’s F&L=20 represents the pinnacle of mobility genetics currently available in Canada. For mammary-focused programs, PROGENESIS ALASTOR (MS=16) and BENJO LINDENRIGHT MAPACHE-P (MS=16) offer the strongest udder genetics among elite type bulls.

Strategic Breeding Decisions for 2026

The December 2025 evaluations create distinct opportunities:

For Balanced Herds: OCD MILAN-ET remains the safe choice—elite LPI, proven stability across proof runs, and solid health traits.

For Component-Focused Operations: BEYOND HI-LEVEL-ET (#4) offers the best combination of high LPI with exceptional fat production. His 67-point LPI gain since August demonstrates strong genetic stability.

For Polled Programs: PROGENESIS SHEAMUS-P at #2 proves polled genetics can compete at the very top without compromising production.

For Type Improvement: PROGENESIS AKSEL and BLONDIN LYNX provide two distinct paths—balanced type versus feet & legs specialization. For mammary focus, consider PROGENESIS ALASTOR (MS=16).

Key Takeaways

  • Component king emerges: BEYOND HI-LEVEL-ET jumped 11 spots to #4 with 165 kg fat—rewriting what’s possible from a top-10 LPI bull
  • Polled shatters the ceiling: PROGENESIS SHEAMUS-P debuted at #2 (4092 LPI), proving elite genetics and hornless no longer trade off
  • Type throne flips: PROGENESIS AKSEL claimed #1 conformation (20 Conf) in his first evaluation, ending WALNUTLAWN PG BRIGHTSTAR’s reign
  • Milan holds, pack closes: OCD MILAN-ET defends #1 at 4137 LPI (+19 from August), but three bulls now sit within 67 points of the crown
  • Percentage play for premium checks: BEYOND HOORAY-ET (#3) posts +1.10% fat and +0.52% protein—numbers built for component pricing

The Bottom Line

These evaluations function like a stock portfolio: OCD MILAN-ET is the blue-chip holding—proven, stable, still delivering. Bulls like PROGENESIS SHEAMUS-P and BEYOND HI-LEVEL-ET are the high-growth plays that just IPO’d into elite territory. The breeders who act on December’s data before their neighbors do will own the genetic edge heading into 2026.

German Rankings Upset: Saturn RDC Shares B&W Throne, Bueno Red Captures Red Crown

Tuesday, December 2nd, 2025

Veterano’s solo reign ends today. Saturn RDC ties at 164 RZG with +0.88% fat. Germany’s new genomic era starts now.

Executive Summary: Germany’s December 2025 evaluations shook up both Holstein leaderboards with new names at the top. Saturn RDC, a Shield son, rockets to 164 RZG—tying Veterano for B&W genomic supremacy—while posting an eye-popping +0.88% fat that makes him the evaluation’s standout component sire. In Red & Whites, Bueno Red seizes the genomic crown at 161 RZG, blending exceptional production (+2,159 kg M) with superior type (121 RZE). The daughter-proven lists also turned over: Precision (148 RZG) now leads B&W with elite udders (132 Eut), while Mask Red (146 RZG) commands the Reds with standout functionality (126 Fun). Sire line trends confirm Real Syn’s grip on B&W genomics, but Shield and Borax Red progeny are rising fast across both breeds. The takeaway for breeders: elite components and top indexes are no longer mutually exclusive—and this proof run proves it.

German genetic evaluations

The December 2025 German genetic evaluations have introduced several notable shifts and new high-ranking sires across both Black & White (Holstein) and Red & White (German Red Holsteins) breeds, according to the latest Interbull data. While top genomic RZG scores remain fiercely competitive, a new shared leader emerged in the B&W category, and the Red & White daughter-proven list crowned a fresh champion.

Here is a detailed report highlighting the changes and new entrants compared to the previous August 2025 rankings.

Black & White (B&W) Holsteins

Genomic Sires: Shared Leadership and Strong Components

The top of the Black & White genomic list (RZG) saw a slight overall shift in index values but welcomed a major new sire joining the former leader.

In the August 2025 evaluation, the undisputed top B&W genomic sire was Veterano (s. Vivify) with an RZG of 166. For December 2025, Veterano’s RZG moderated slightly to 164, resulting in a shared number one spot with the Shield son Saturn RDC.

  • Saturn RDC (HB-Nr 103000) debuts strongly at 164 RZG. This newcomer is a notable component specialist, boasting exceptional fat content at +0.88% F (+110 kg F) and a strong mammary score (Eut) of 126. Saturn RDC’s RZhealth of 132 is exceptional.

Other key B&W genomic sires and their movement:

  • Evenstar (s. Real Syn) dropped slightly from 164 RZG (August) to 163 RZG (December, rank 3).
  • Realpower (s. Real Syn) also fell slightly from 164 RZG (August) to 163 RZG (December, rank 4). Realpower remains an outstanding production sire with +1,986 kg M and extremely high fat percentages at +0.61% F (+154 kg F).
  • Two Real Syn sons continue to impress in the genomic charts:
    • DG Rico debuted (or was highlighted in the latest summary) at +160 RZG, noted for his +126 RZE(Type), +1,649 kgM, +0.51% F, and +0.02% P.
    • His full brother, DG Eliandro, achieved a 158 RZG and impressive type figures (+134 RZE, +1,582 kgM).

Daughter Proven Sires (Active AI Bulls, 500+ DEU Dtrs)

The Daughter Proven category saw significant turnover at the top, with bulls featuring at least 500 German daughters.

In August 2025, Mirco (s. Mick) led the domestic daughter-proven list at 144 RZG. The December 2025 evaluation introduces a new leader:

  • Precision (HB-Nr 575319), ranking #1 with 148 RZG. This sire excels in conformation, showing an RZE of 133 and a particularly high Udder score (Eut) of 132.

Other notable changes in the daughter-proven segment:

  • Zivet (s. AltaZarek), his RZG decreased slightly from 147 (August Interbull Top 1) to 146 (December, rank 2), while increasing his milk production to +2,074 kg M.
  • Mirco dropped two points, moving from 144 RZG (August #1) down to 143 RZG (December #3).
  • Sunrise also saw a slight drop in RZG, moving from 142 RZG (August Interbull #9) to 141 RZG (December #3 in the domestic list).

German Red Holsteins (R&W)

Genomic Sires: Bueno Red Takes the Lead

The Red & White genomic list also experienced a shift at the very top (RZG 161).

In August 2025, the top three Red & White genomic sires were tightly grouped at 161 RZG: Schach (s. Skat P RDC), Create P (s. CR 7 P), and Coco Red P (s. Cop Red PP).

In the December 2025 Interbull genomic rankings, the new #1 sire is Bueno Red (HB-Nr 823382, s. Borax Red) with a 161 RZG. Bueno Red stands out for excellent production figures (+2,159 kg M) and exceptional Type (RZE 121).

Key movements among the top R&W genomic sires:

  • Create P (161 RZG in August) settled at 159 RZG (December rank 2).
  • Cardiff P (160 RZG in August) landed at 159 RZG (December rank 3).
  • Coco Red P (161 RZG in August) scored 159 RZG (December rank 4).
  • Schach dropped slightly to 159 RZG (December domestic ranking #5), falling out of his shared #1 position from August.
  • A new high entry in the top 5 is Maestro (s. Shield), achieving 159 RZG and strong components including +0.83% F and +0.41% E.

Daughter Proven Sires: Mask Red Ascends

The R&W Daughter Proven category also saw a leadership change. The August 2025 Interbull list was led by Rammstein (s. Jayvano) at 145 RZG.

For December 2025, Mask Red (s. Stamkos) is confirmed as the new chart-topper in the R&W RZG Daughter Proven index with 146 RZG. Mask Red offers solid production (+1,354 kg M) and excellent Functionality (Fun 126).

The previous leader, Rammstein, moved to #2 at 145 RZG. Importantly, Rammstein increased his components proof, now showing +0.01% F and +0.15% P.

Other major movements in R&W daughter-proven rankings (500+ DEU daughters):

  • Ginger (s. Gywer RDC) saw an RZG decrease from 143 (August Interbull Rank 2) to 142 RZG (December Domestic Rank 1), but remains a strong milk bull (+2,719 kg M).
  • Money P (s. Match P) also dropped slightly from 138 RZG (August Domestic Rank 1) to 137 RZG (December Domestic Rank 2).
  • Garnier (s. Gywer RDC) decreased from 136 RZG (August Domestic Rank 2) to 135 RZG (December Domestic Rank 3).

The December 2025 German evaluation highlights the quick succession and strong performance of young genomic sires, particularly those sired by Real Syn (B&W), and the emergence of Shield and Borax Red progeny in the R&W categories. The Daughter Proven lists show Precision and Mask Red successfully capitalizing on their proof increases to claim the top spots in their respective breeds.

Key Takeaways:

  • Saturn RDC Ties for B&W Crown: Shield son debuts at 164 RZG—matching Veterano—with +0.88% fat that sets a new standard for component excellence at elite index levels
  • Bueno Red Seizes Red Leadership: New R&W genomic #1 at 161 RZG delivers both volume (+2,159 kg M) and type (121 RZE)—a rare combination
  • Proven Lists Overturn: Precision (148 RZG, 132 Eut) now leads B&W daughter-proven; Mask Red (146 RZG, 126 Fun) takes R&W top spot
  • Sire Line Trends: Real Syn continues B&W genomic dominance, but Shield and Borax Red progeny are ascending rapidly in both breeds
  • Breeder Action: High-component, high-index genetics are no longer trade-offs—these December leaders prove you can have both

Swiss Shakeup: Monset (+1603) Claims ISET Crown as Boston Plummets 52 Points

Tuesday, December 2nd, 2025

Boston was untouchable at +1645 ISET. Four months later, he’s lost 52 points and his crown. The new Swiss #1? Hadley son Monset at +1603.

Executive Summary: Switzerland’s December 2025 ISET rankings delivered a stunning reversal: TGD-Holstein Monset (+1603), a Hadley x Gameday cross, seized the genomic throne after Sous-Moron Boston plummeted 52 points—from +1645 to +1593—in just four months. This collapse, among the sharpest ever recorded for a reigning Swiss #1, starkly illustrates the volatility risk of concentrating matings on young genomic sires. The Gameday maternal line now underpins three of five top bulls, creating genetic concentration that demands careful inbreeding management in progressive herds. Breeders seeking production alternatives should consider Progenesis Timeout (+141 kg fat, +0.83%) and Torchlight (+92 kg protein, +1584 ISET)—elite components outside the Hadley stack. For conformation priority, DG Blackburn leads genomic type at +136 ITP, while daughter-proven NH DG Arrow (+128 ITP) offers proven reliability over genomic projection. The December lesson is unambiguous: rankings reward diversified mating strategies, and any sire—regardless of peak index—can lose 50+ points before his first daughters calve.

Swiss ISET Genomic Rankings

A New Name at the Top

The December 2025 Swiss genetic evaluations have reshuffled the genomic leaderboard in ways that should give every breeder pause. TGD-Holstein Monset, a Hadley son bred from a Gameday dam, now sits atop the ISET (Total Index) rankings with a score of +1603. That’s not a typo—the new #1 actually posts a lower index than the old #1 held just four months ago.

What’s interesting here is how this leadership change happened. Monset didn’t surge past Boston through some spectacular gain. Rather, Sous-Moron Boston—the bull who looked bulletproof in August at +1645 ISET—experienced a 52-point correction that dropped him to +1593. In genomic evaluation terms, that’s a significant recalibration. Boston, a Casting son also out of a Gameday dam, now sits in second place behind a bull he would have comfortably outranked just one evaluation cycle ago.

Rounding out the top three is TGD-Holstein Beautyman, a Globed x Astral cross holding steady at +1586 ISET. Beautyman has proven remarkably consistent across evaluations—he sat at +1590 in August—which is exactly the kind of stability progressive breeders should value.

December 2025 Genomic ISET Top Performers

Here is a look at the top rankings in the genomic list for December 2025:

Rank (Dec ’25)NameSire x Dam’s SireISET ScoreFat kg / %Protein kg / %
1TGD-Holstein MONSETHADLEY x GAMEDAY160397 kg / 0.51%68 kg / 0.30%

For comparison, here’s where things stood in August—note how dramatically the picture has shifted:

5Swissgen EMPIREBLAKELY x CAPTIVATING157374 kg / 0.45%48 kg / 0.22%

Understanding Boston’s 52-Point Correction

So what happened to Boston? This is where the mechanics of genomic evaluation matter for practical breeding decisions.

Young genomic sires carry what geneticists call “reliability risk.” When a bull has no milking daughters—or very few—his genomic prediction is essentially a statistical estimate based on DNA marker associations with the reference population. Research from the Council on Dairy Cattle Breeding shows that genomic evaluations for young bulls typically carry reliabilities around 70-75%, compared to 90%+ for daughter-proven sires. That 25-30% uncertainty has to go somewhere, and sometimes it goes against you.

As more data accumulates—whether from the bull’s own daughters entering production, updates to the reference population, or methodology refinements—those predictions get recalibrated. The dramatic swings we’re seeing in genomic rankings aren’t bugs in the system; they’re features. They reflect the reality that early genomic predictions are educated estimates, not guarantees.

I’ve noticed that bulls gaining or losing 50+ points in a single evaluation cycle aren’t unusual in genomic rankings, though it’s certainly jarring when it happens to the reigning #1. What’s worth noting is that Boston’s component predictions also shifted—his fat yield estimate dropped from 98 kg to 87 kg, while his fat percentage moved from 0.44% to 0.38%. These aren’t minor adjustments.

The practical takeaway? Any breeding program built heavily around a single young genomic sire carries a concentration risk that can materialize faster than most producers expect.

The Gameday Question: Maternal Dominance and Inbreeding Pressure

Looking at the December rankings, something jumps out immediately: three of the top five ISET sires trace to Gameday dams. Monset, Boston, and Torchlight all carry Gameday on their maternal side. That’s a lot of genetic eggs in one basket.

Gameday (RMD-Dotterer SSI Gameday-ET) earned his reputation honestly—he was the breed’s #1 sire for Net Merit and GTPI when he debuted, combining high production with solid health and type traits. His influence through both sons and daughters has been enormous. But when a single bull’s genetics dominate multiple pathways to the top of the rankings, inbreeding management becomes a real operational concern.

For herds that have used Gameday-sired bulls heavily over the past few years—and many have—the December rankings present a practical challenge. Using Monset or Boston on Gameday granddaughters pushes inbreeding coefficients into territory that can affect fertility, calf vigor, and lifetime productivity. What farmers are finding is that mating software becomes essential, not optional, when the top of the rankings shares this much common ancestry. The alternative—breeding for maximum ISET without inbreeding checks—is a strategy that works until it doesn’t.

Component Alternatives Worth Considering

Not every herd needs to chase the top ISET number. For operations focused on butterfat performance or protein premiums, the December rankings offer some compelling alternatives that fly a bit under the radar.

Progenesis Timeout (+1584 ISET) posts remarkable component numbers: +141 kg fat with a +0.83% butterfat deviation. That’s elite fat production with the percentage improvement that component-focused markets reward. His Peregrine x Dzunda pedigree also sits outside the Hadley/Gameday concentration, offering some genetic diversity for herds looking to manage inbreeding pressure.

Progenesis Torchlight (+1584 ISET) takes a different angle—he’s the protein king of this group at +92 kg protein with a +0.23% deviation. For cheese-market producers or those selling into protein-premium contracts, Torchlight’s profile makes a lot of sense. He does carry Gameday on his dam’s side, though, so inbreeding checks remain important.

What’s interesting here is the production gap between these component specialists and the ISET leaders. Beautyman, sitting at #3 ISET, posts just +49 kg fat and +57 kg protein—strong index, but not the component punch that Timeout and Torchlight deliver. Different bulls for different breeding objectives.

Type Index (ITP): Balancing Genomic Promise and Proven Reliability

For breeders who prioritize conformation alongside production, the type rankings tell their own story.

DG Blackburn leads the genomic ITP category with a +136 type index, a genuinely impressive type index. He’s a Davinci son tracing to the Regancrest-PR Barbie EX-92-USA cow family—genetics that have consistently produced style and dairy strength. For herds targeting show-ring success or breeding-stock sales, Blackburn’s genomic type profile is hard to ignore.

But here’s where the discussion of genomic volatility becomes relevant again. Blackburn’s +136 ITP is a genomic prediction with the same reliability considerations we discussed with ISET rankings. Bulls can and do move significantly on type evaluations as daughter information accumulates.

That’s why NH DG Arrow deserves attention as the #3 daughter-proven ITP sire at +128 ITP. Arrow, bred by Nosbisch Holsteins and Diamond Genetics, offers something Blackburn can’t yet provide: actual daughter performance data backing up his type prediction. The 8-point gap between Blackburn’s genomic +136 and Arrow’s proven +128 represents the premium breeders pay for certainty versus projection.

Strategic Breeding Takeaways

December’s Swiss rankings offer several clear signals for breeding program planning:

  • For high-index programs: Monset’s rise to #1 makes him an obvious choice for herds chasing maximum ISET. But his Hadley x Gameday pedigree demands careful inbreeding management. Consider pairing Monset matings with outcross alternatives, such as Timeout or Beautyman, to maintain genetic diversity across the herd.
  • For component-focused operations: Timeout (+141 kg fat, +0.83%) and Torchlight (+92 kg protein) offer elite production traits that may actually deliver more economic value than top ISET bulls in premium-market situations. Don’t let index rankings blind you to component opportunities.
  • For type-priority breeders, the genomic-versus-proven trade-off between Blackburn (+136 ITP genomic) and Arrow (+128 ITP proven) is a fundamental risk-management decision. Using both strategically—Arrow on your best cows where you can’t afford a miss, Blackburn on animals where you can accept more variance—often makes more sense than choosing one approach exclusively.
  • For everyone: Boston’s 52-point correction is a reminder that genomic rankings are probability distributions, not certainties. The generation interval advantages of young genomic sires are real—research shows the sire-of-bulls pathway has compressed from nearly 7.5 years to under 2.5 years since genomic selection began. But those advantages come with volatility that daughter-proven sires don’t carry.

The Bigger Picture

What December’s Swiss evaluations really demonstrate is something geneticists have been saying since genomic selection launched: these tools work best when used thoughtfully, not blindly.

The dramatic swings we see in genomic rankings aren’t evidence that the system is broken. They’re evidence that early predictions carry meaningful uncertainty—uncertainty that resolves as more data accumulates. Bulls like Beautyman, who hold relatively steady across evaluations, may ultimately prove more valuable than higher-indexed bulls who experience significant corrections.

For breeders, the lesson isn’t to abandon genomic sires—their contribution to genetic progress has been profound. The lesson is to build breeding programs around diversification rather than concentration. Use multiple sire lines. Balance genomic potential with proven reliability. Run inbreeding checks before every mating decision, not just occasionally. The bull who sits at #1 today may not be there in April. But a breeding program built on sound genetic principles will perform regardless of which individual bull wears the crown.

August 2025 Proofs: New Kings, Big Swings, and What It Means for Your Herd

Wednesday, August 13th, 2025

Bulls losing 102 points overnight while proven sires gain $2,400/cow advantage? August’s genomic chaos changes everything we know.

EXECUTIVE SUMMARY

The August 2025 genetic evaluations reveal a critical shift in the dairy industry, as the proven reliability of daughter-backed sires increasingly outshines the volatile promise of their genomic counterparts. This trend is highlighted by major ranking changes, including Stantons Remover PP leaping to the #1 proven spot in Canada, while genomic bulls like Cookiecutter Hadley-ET experienced dramatic drops. The displacement of established sires like Genosource Captain in the UK further signals a rapid industry shift towards functional traits, such as health and efficiency. This dynamic underscores a move by breeders to prioritize real-world economic performance, exemplified by GENOSOURCE RETROSPECT-ET’s dominance in the US Net Merit rankings, leading to breeding strategies that now favor the stability of proven genetics.

KEY CHANGES

  • Stantons Remover PP: The biggest mover, leaping from #7 to become the new #1 proven sire in Canada (LPI) after his first daughters validated his genomic potential.
  • Cookiecutter Hadley-ET: A prime example of genomic volatility, going from #2 to #10 in the Italian genomic rankings in a single evaluation cycle.
  • OCD Trooper Sheepster: Emerged as the new #1 daughter-proven sire in the UK (£PLI), showcasing a desirable combination of production and a high lifespan improvement.
  • GENOSOURCE RETROSPECT-ET: The new leader for Net Merit ($NM) in the US, headlining Genosource’s complete domination of the economic-focused index.
  • Genosource Captain: A significant change, this former industry-leading sire dropped to fifth place in the UK and 3rd place in the US, highlighting the rapid genetic progress and shifting priorities towards health and efficiency traits.
  • Evenstar & Pennywise: A pair of “twin” sires who became the new #1 genomic leaders in Germany ($RZG), both achieving an elite score of 164.
  • Peak Spellbound-ET: Surged to become the new #1 genomic sire in Italy ($gPFT), noted for his exceptional component percentages that appeal to the cheese market.

The August 2025 genetic evaluations have delivered the most dramatic ranking reshuffles we’ve seen in years, with proven sire Stantons Remover PP leaping from #7 to #1 in Canada, while Italian genomics swung by 100+ points in single evaluations. The real story? Proven reliability is increasingly outperforming genomic promises as economic pressures force progressive breeders to prioritize profitable genetics over flashy TPI numbers.

Look, I’ve been watching genetic evaluations for over two decades, and what just dropped in August 2025 has me scratching my head in the best possible way. We’re seeing ranking shifts that would’ve been unthinkable just a few years ago—and the implications for your breeding program are massive.

The thing that’s really got my attention isn’t just the new leaders (though they’re impressive), it’s this growing tension between what genomics promise and what proven bulls actually deliver. And frankly, some of the volatility we’re seeing should prompt every breeder to pause before they become too aggressive with unproven genetics.

The Great Genomic Reality Check—And Why It Matters to Your Bottom Line

Here’s what’s happening across the major Holstein markets, and it’s telling a story that every progressive breeder needs to understand. We’re looking at the United States, Canada, the UK, Germany, and Italy—basically the genetic powerhouses that drive most of our industry decisions.

The pattern that’s emerging? Genomic predictions are becoming increasingly volatile, while proven bulls are demonstrating the kind of consistency that actually pays the bills. Take what just happened in Italy—Cookiecutter Hadley-ET dropped from #2 to #10 genomic, losing 102 points in one evaluation cycle. That’s not a small adjustment; that’s a complete reversal of fortune.

Meanwhile, proven sire ZFZ Crisalis RF gained 29 points, strengthening his position as #1. The guy has thousands of daughters, actually milking in real barns, dealing with real feed costs and real heat stress. There’s something to be said for that kind of validation.

What really drives this home is the German comparison. Their genomic leaders, Evenstar and Pennywise, both reached RZG 164—that’s a 17-point advantage over proven leader Zivet, who reached RZG 147. Now, if you’re doing the math on lifetime profit, that gap represents serious money… if the predictions hold true.

Marco Winters from AHDB put it perfectly when he looked at the UK situation: “The six new graduates in the top 10 already have around 7,000 heifers registered in UK milk-recorded herds, with some now milking. Their proven £PLI values deviate by just one point on average from their earlier genomic predictions.”

That’s the kind of validation that makes you feel good about using genomics early. But here’s the thing—not every market is showing that kind of accuracy.

North America: Where Economic Reality Meets Genetic Hype

The United States: Genosource’s Economic Domination

What’s fascinating about the US August proofs is how they reveal a fundamental shift toward economic reality. Sure, BEYOND HI-LEVEL-ET claimed the #1 genomic spot at +3539 TPI, but honestly, that’s not the story that’s going to matter to your milk check.

The real story is how Genosource has completely taken over the Net Merit rankings. I mean completely. GENOSOURCE RETROSPECT-ET leads at +1317 NM$, followed by his stable mates GENOSOURCE ENDURANCE-ET (+1233NM) and GENOSOURCE PURDY-ET (+1222 NM$).

This isn’t a coincidence—this is systematic breeding for traits that actually make money rather than chasing TPI points that look good on paper but don’t always translate to profitability. And with feed costs where they are in 2025, that focus on economic merit is becoming non-negotiable.

In the proven ranks, SDG CAP GARZA-ET is leading at +3488 TPI with 98% reliability. What I like about Garza is his balance—+146 lbs fat, +53 lbs protein, and +3.7 PL. Those are the kind of numbers that keep operations profitable when everything else goes sideways.

Canada: The Remover Revolution (And What It Really Means)

Now this is where August got really interesting. Stantons Remover PP made this spectacular jump from #7 in April to #1 in August (+3897 LPI). That’s not just a statistical blip—this bull’s backed by 234 daughters across 32 herds, which means we’re looking at real-world validation of genomic predictions.

What strikes me about Remover is his profile. He’s not just high-scoring, he’s balanced in exactly the ways that Canadian producers need as replacement costs keep climbing. The durability traits are there, the production is solid, and crucially, he’s proving himself in diverse management systems across the country.

The genomic young sire category is where things get really exciting, though. OCD Milan-ET leads at +4118 GPA LPI, and his numbers tell a story: +638 Milk, +108 Fat, plus strong type (+10 Mammary System, +6 Feet & Legs). This combination of production and structural soundness is exactly what the Canadian industry has been selecting for—cattle that can handle our diverse climate and management challenges.

European Markets: The Functional Excellence Revolution

United Kingdom: When Genomic Predictions Actually Work

The UK market gave us probably the strongest validation of genomic accuracy we’ve seen recently. Six new daughter-proven sires graduated into the top 10 PLI positions, and here’s the kicker—their proven values are matching their genomic predictions almost perfectly.

OCD Trooper Sheepster emerged as the new proven leader at £779 PLI. His production numbers are impressive (47.8kg fat, 35.7kg protein), but what really catches my attention is the +113-day lifespan improvement. With replacement costs exceeding £ 2,000 per animal, longevity traits like these are becoming the difference between profit and loss.

The genomic leader, Peak AltaValuepack, at £877 PLI, shows even stronger longevity (+122 days) while maintaining solid production (+785kg milk). This represents what I think is the modern ideal—comprehensive genetic merit that addresses both production and durability.

What’s particularly noteworthy is how Genosource Captain dropped to fifth place (£723 PLI) despite having over 2,000 UK milking daughters. This displacement illustrates how rapidly genetic progress can transform breeding hierarchies when functional traits take precedence over other traits. The Captain has been a reliable choice for years, but the industry’s moving toward health, fertility, and efficiency traits faster than many expected.

Germany: Precision Breeding at Its Finest

German evaluations consistently demonstrate why their breeding program is considered world-class. Proven leader Zivet commands RZG 147 through this impressive balance: +1,971 kg milk, +88 kg fat, +86 kg protein, combined with functional traits (RZN 121, RZGes 113) that actually work in commercial settings.

The genomic sphere produced these twin leaders in Evenstar and Pennywise, both at RZG 164. Evenstar’s projections (+2,090 kg milk, +120 kg fat, +69 kg protein, RZN 134) position him as a premium choice for operations serious about maximizing both production and longevity.

What’s interesting is how Red Holstein genetics keep showing up in top rankings. Ginger leads proven sires at RZG 143 with +2,638 kg milk through 510 daughters. In genomics, Schach achieved RZG 161. This demonstrates continued genetic progress in color variants—something that’s becoming increasingly important as producers seek ways to differentiate their cattle.

Italy: The Volatility That Should Worry Everyone

The Italian evaluations provided the starkest illustration of genomic volatility I’ve seen. Peak Spellbound-ET surged to #1 genomic position at 5458 gPFT—he’s an Overdrive son showing impressive components (+1.07% fat, +0.54% protein) that appeal to Italy’s cheese-focused industry.

But here’s what should concern every breeder: the dramatic swings in genomic rankings. Bulls gaining or losing 100 points or more in a single evaluation raise serious questions about reliability. This underscores why the Italian proven bull rankings, where ZFZ Crisalis RF maintains steady leadership at 5169 gPFT, provide such important stability.

The Italian ICS-PR€ index tells another story entirely. Smartie P-ET leads with 1398 ICS-PR€, demonstrating the economic reality that in value-added dairy systems, components matter more than volume. This is particularly relevant as more operations explore premium markets.

The Trends That Are Reshaping Everything

Health and Longevity: No Longer Optional

What’s becoming increasingly clear across all markets is that health and longevity traits are no longer nice-to-have features—they’re essential for profitability. PROGENESIS WATCHMAN’s elite 8.6 Health Index represents the kind of defensive genetics that operations need against rising veterinary costs.

The UK’s emphasis on HealthyCow values and Germany’s focus on RZGes scores reflect an industry-wide recognition that profitable cows must first be healthy cows. This isn’t just about animal welfare (though that matters), it’s about economic survival in an environment where every sick cow threatens your bottom line.

Component Production: The New Economic Reality

The shift toward fat and protein production rather than volume alone is evident everywhere you look. German proven sire Ginger’s +2,638 kg milk production demonstrates that volume still matters, but bulls like Peak Spellbound-ET, with +1.07% fat, are capturing attention in component-focused markets.

This trend makes sense when considering where milk prices are headed. Component premiums are becoming more significant, and operations that can deliver high-quality fat and protein are seeing better returns than those focused purely on volume.

Polled Integration: Finally Happening Seamlessly

Polled genetics are showing up in top rankings without the performance compromises we used to see. Germany’s Create P achieving RZG 161 and Canada’s Vogue A2P2-PP maintaining +15 CONF demonstrate successful integration of polled traits into elite genetic packages.

This matters because consumer pressure around dehorning isn’t going away, and having polled options that don’t sacrifice performance removes a major management headache.

The Bloodline Concentration Problem

Here’s something that should concern everyone: the dominance of specific sire lines across multiple countries. Overdrive sons appear in top rankings across markets, while Genosource genetics dominate US economic merit rankings.

This concentration delivers short-term genetic progress, but it’s creating long-term risks to breed adaptability. We’ve seen this movie before with other breeds, and it doesn’t end well if we’re not careful about maintaining genetic diversity.

Economic Pressures Driving Everything

Feed Efficiency: The Make-or-Break Trait

With feed costs still elevated in 2025, bulls showing superior feed conversion are becoming premium choices. The UK’s emphasis on Maintenance Index scores and Italy’s ICS-PR€ rankings reflect an industry that can no longer afford inefficient genetics.

Genosource Captain’s Feed Advantage, with a +255, exemplifies why these traits matter so much. When margins are this tight, feed efficiency often determines profitability more than raw production numbers. This is basic math that every operation needs to understand.

Replacement Costs: Why Longevity Pays

Rising replacement heifer costs are elevating longevity traits to critical importance. OCD Trooper Sheepster’s +113 days lifespan improvement and Peak AltaValuepack’s +122 days longevity represent real economic value when replacements cost $2,000+ per animal.

The math here is straightforward—every additional lactation from a cow represents thousands of dollars in value. Operations that ignore longevity traits in favor of short-term production are essentially choosing to hemorrhage money on replacement costs.

What This Means for Your Breeding Strategy

The Portfolio Approach (Because Balance Matters)

The volatility we’re seeing suggests genetic diversification rather than relying on a single bloodline. Successful operations are adopting portfolio approaches—combining proven reliability with selective use of high-potential genomics. My recommendation? Build genetic portfolios with 60-70% proven sires and 30-40% genomic young sires, adjusting based on your risk tolerance and genetic progress objectives. This captures advancement while maintaining reliability.

Market-Specific Selection (One Size Doesn’t Fit All)

Each market’s payment systems and management conditions require tailored strategies. Italian producers focused on cheese production, with weight component percentages, differently than Canadian operations that sell fluid milk.

UK producers must balance production with stringent health and welfare requirements.

This means you can’t just follow rankings blindly—you need to understand what traits actually drive profitability in your specific market situation.

Timing Genomic Adoption (When to Jump, When to Wait)

The UK’s validation of genomic predictions through proven daughters provides confidence for early adoption of superior young sires. However, the Italian experience suggests that extensive use of unproven genetics carries a substantial risk.

Successful breeders are adopting measured approaches—using genomic bulls selectively while maintaining core breeding programs on proven genetics. It’s about being progressive without being reckless.

Looking Forward: The Real Strategic Imperatives

What the August 2025 evaluations really reveal is that the industry is striking a balance between the promise of genomics and economic reality. The winners aren’t chasing the highest TPI or PLI scores—they’re building profitable, sustainable herds adapted to their specific conditions.

Success belongs to breeders who strategically combine proven genetics as their foundation with selective genomic advancement. The future isn’t about choosing between proven and genomic selection—it’s about leveraging both approaches to create cattle that thrive in an increasingly challenging environment.

The real winners are already emerging, and they’re not just showing up in rankings. They’re showing up in milk checks and bottom lines of operations that have learned to balance genetic potential with economic reality. Because at the end of the day, that’s what actually matters in this business.

August 2025 US Proofs: A Guide to the Real Winners and Winning Strategies

Wednesday, August 13th, 2025

The August proofs are out. Don’t just chase the #1 bull. Discover the winning strategies that will actually drive your profitability.

Executive Summary: The August 2025 sire proofs reveal a key strategic crossroads for dairy producers, contrasting the high-potential genomics of the new #1 GTPI® sire, BEYOND HI-LEVEL-ET, with the data-backed reliability of proven powerhouses like SDG CAP GARZA-ET. This analysis delves deeper than the headline rankings, questioning the industry’s focus on TPI points versus true on-farm profitability. It highlights the dominance of Genosource in the Net Merit category, led by GENOSOURCE RETROSPECT-ET, as a case study in breeding for economic success. Ultimately, the article argues that the “real winners” are sires that deliver balanced traits, such as health and longevity, urging producers to build resilient, profitable herds rather than simply chasing the highest-ranking genomic bull.

sire selection guide, dairy cattle breeding, dairy farm profitability, Holstein genetics, genomic sires

The August 2025 sire proofs are out, and they paint a clear picture of the two paths available to dairy producers: the high-risk, high-reward world of elite genomics, and the reliable, data-backed foundation of proven sires. Understanding the leaders in each category—and the larger trends they represent—is crucial for building a profitable breeding strategy in today’s demanding market.

Genomic Leaders: A Glimpse into the Future

The top of the young sire list is where we see the absolute cutting edge of genetic potential.

  • The New #1: BEYOND HI-LEVEL-ET has claimed the top spot at +3539 TPI (Over 1 year of age). His well-rounded profile features a +1048 NM$, solid production, and a strong +7.0 Health Index, making him a complete package on paper.
  • The Contenders: Right behind him, OCD RADICAL JOSH ALLEN-ET (+3534 TPI) offers a higher Net Merit at +1097 NM$ and massive milk (+1765 lbs). However, for many producers focused on trouble-free cows, PROGENESIS WATCHMAN is a standout. His elite 8.6 Health Index offers a powerful defense against costly vet bills and labor challenges.

Proven Sires: The Gold Standard of Reliability

While the genomic list offers potential, the proven sire list delivers confidence backed by thousands of real-world milking daughters.

  • The Proven Powerhouse: SDG CAP GARZA-ET leads this list at +3488 TPI with an exceptional 98% reliability. His combination of high-volume components (+146 lbs fat, +53 lbs protein) and solid longevity (+3.7 PL) makes him a go-to sire for predictable results.
  • The Veterans: OCD TROOPER SHEEPSTER-ET (+3458 TPI) and GENOSOURCE CAPTAIN-ET (+3429 TPI) are titans of the industry. Sheepster built his reputation on massive production validated across diverse environments, while Captain is a cornerstone sire known for building lasting, profitable cow families with his 99% reliability.

The Genosource Phenomenon: Cracking the Profitability Code

Across the rankings, one trend is undeniable: Genosource’s dominance in delivering profitable genetics.

  • Net Merit Leaders: GENOSOURCE RETROSPECT-ET is crushing the competition at +1317 NM, driven by elite fat production (+144lbs) and longevity (+6.0PL, +7.2 Health Index). He is followed by a stable of herd mates like GENOSOURCE ENDURANCE-ET (+1233NM) and GENOSOURCE PURDY-ET (+1222 NM$).
  • The Strategy: This isn’t just about genetic concentration. Genosource has clearly developed a winning formula for identifying sires that excel in traits directly driving profit. Their laser focus on the Net Merit formula is a strategy the entire industry can learn from.

The Color Advantage: Grounded Genetics in a Volatile Market

For breeders looking for solid performance without the volatility of chasing the #1 genomic bull, the Red & White and Red Carrier lists offer compelling opportunities.

  • Red & White (R&W): While SIEMERS RLE PAPAYA-RED-ET leads at +3245 TPI, the bull to watch for commercial durability is APRILDAY ORPHS AESOP-RED-ET (+3195 TPI). His +5.3 PL and 8.2 Health Index are exactly what’s needed to lower involuntary culling when replacement heifers are at a premium.
  • Red Carrier (RC): S-S-I SIEMERS FALCIFORM-ET (+3305 TPI) and OCD DOMINANCE SUNDAY-ET (+3304 TPI) both offer elite production packages, though Sunday’s 3.02 SCS warrants careful mating to maintain udder health.

Type Specialists: Precision Tools for Conformation

The top of the PTAT list is reserved for specialists. These bulls fill a specific niche in breeding programs—think of them as surgical tools, not everyday workhorses.

  • The Extreme Tier: SHG LEGO (+3.89 PTAT) and REDCARPET STORY ARC-ET (+3.88 PTAT) remain the clear leaders for extreme type.
  • The Balanced Option: SIEMERS HULU PALDWYN-ET deserves special attention. At +3.18 PTAT combined with a strong +3069 TPI, he represents one of the best options for improving conformation without sacrificing significant overall genetic merit.

The Bottom Line: Breeding for Profit, Not Just Points

When making breeding decisions, consider these key takeaways from the August proofs:

  1. Study the Winners: Genosource’s Net Merit dominance isn’t an accident. Analyze their approach to selecting for the traits that drive economic success.
  2. Prioritize Health: With soaring costs, the high Health Index scores on bulls like Watchman and Aesop are becoming non-negotiable for building a resilient and profitable herd.
  3. Use Type Strategically: Leverage extreme PTAT sires as corrective tools for your worst-conformed animals, but build your herd’s foundation on profitable production and health genetics.

The smart money isn’t just chasing the latest #1 genomic bull. It’s about learning from proven programs and building a balanced herd that can thrive, no matter what the market throws at you.

Canadian Holstein Genetics Heat Up: A New #1 Proven Sire and What the August ’25 Rankings Really Mean

Tuesday, August 12th, 2025

The August ’25 proofs just dropped & the rankings are shaken up! A new sire takes the proven crown & a genomic superstar claims #1. See who’s making moves.

EXECUTIVE SUMMARY: The August 2025 Canadian Holstein genetic evaluations signal significant shifts in sire leadership, headlined by Stantons Remover PP’s notable ascent to the #1 daughter-proven LPI position at +3897, a substantial leap from his #7 rank in April. In the genomic rankings, OCD Milan-ET now leads with a +4118 GPA LPI, climbing from fourth place and showcasing a balanced profile of production and strong type scores. This trend toward balanced genetics is further highlighted by conformation leaders like genomic sire Walnutlawn PG Brightstar (+20 CONF) and proven sire Blondin Energy (+17 CONF), who combine elite type with solid production, reflecting a broader industry focus on creating durable, high-output animals.

Canadian Holstein proofs, LPI sires, dairy herd profitability, genomic testing dairy, top Holstein sires

The current state of Canadian Holstein genetics is fascinating, and it has me pretty excited about where this industry is heading. In reviewing the August 2025 genetic evaluations, there are some real eye-opening moves in the bull rankings that every producer should be paying attention to.

The Proven Sires: A New King Is Crowned

Let’s start with the heavyweights. In what is probably the biggest news of this proof round, Stantons Remover PP has made a significant leap to the top, claiming the #1 LPI spot at +3897. This is a huge jump from his #7 position just back in April. What strikes me about Remover is how he’s backed by real-world proof—we’re talking about a bull with 32 herds and 234 daughters contributing to those numbers. That’s the kind of reliability that builds confidence when you’re making decisions that will impact your herd for years.

Here’s where it gets interesting: the top of the list is a game of consistency and power. Siemers Renegade Rozline-ET holds strong in second place with an LPI of +3891, showing the staying power of the Renegade sons. When you see his component numbers from previous runs, you understand why producers keep coming back to this bloodline. Siemers Rengd Parfect-ET rounds out the top three at +3874 LPI, proving that his daughters are translating those genomic predictions into real milk checks, which is what ultimately matters when you’re trying to keep the lights on.

Young Bulls Making Waves

Now, the genomic young bull rankings… this is where the future is forged. OCD Milan-ET has climbed from fourth place in April to top the GPA LPI charts at a massive +4118 with a powerful +3281 PRO$ . What’s particularly noteworthy is his balance; he combines solid production (+638 Milk, +108 Fat) with strong type scores: +10 for Mammary System and +6 for Feet & Legs. That blend of production and durability is crucial, as input costs continue to rise.

April’s leader, OCD Monkey-ET, is right behind at +4105 GPA LPI, alongside Progenesis Impulse at +4067 GPA LPI. The Impulse story is fascinating because you’re seeing exceptional component percentages (+0.38% Protein) combined with a reasonable milk volume. That’s the sweet spot that many producers are chasing—enough volume to generate a cash flow, but with components that actually pay.

And here’s something that caught my eye: Adaway Beyond Fitness-ET at #5 is showing a massive +0.42% Protein. Those are the kinds of numbers that make your milk check smile.

Conformation Leaders Tell a Story

The conformation rankings reveal a telling shift. Walnutlawn PG Brightstar leads the genomic bulls with a stunning +20 CONF score, and he does it without sacrificing production, boasting an impressive +1286 Milk. But what’s really interesting is seeing bulls like Benjo Lindenright Mapache-P (+19 CONF) and Fepro Langundo (+18 CONF) in the top three—these aren’t just show winners; they’re functional animals with solid production profiles to back it up.

Among the proven bulls, familiar names are holding strong. Blondin Energy leads at +17 CONF, followed by Black Silver Crushabull Stan at +16 CONF. The Crushabull influence just keeps showing up in these rankings, which tells you something about the staying power of that line. And right there with them is Vogue A2P2-PP, a polled bull holding his own with a solid +15 CONF. This continued presence of polled genetics in top conformation spots shows how successfully these traits are being integrated.

Germany’s August 2025 Holstein Rankings Reveal New Genetic Kings

Tuesday, August 12th, 2025

German sire just hit RZG 148 – that’s $2,400 more lifetime profit per cow than industry average bulls.

EXECUTIVE SUMMARY: Just spent the morning analyzing Germany’s August 2025 Holstein evaluations, and the results are frankly stunning. The pace of genomic progress is relentless—we’re seeing genomic bulls like Evenstar and Pennywise hitting an incredible RZG 164, while the top daughter-proven bull, Zivet, commands the proven rankings at an already elite RZG 147. For breeders, that 17-point RZG gap between the proven king and the new genomic leaders can translate to thousands of dollars in lifetime profit per cow. The standout in the proven list is Zivet at RZG 147, delivering over +1,900 kg of milk with phenomenal components. In the Red Holstein world, Ginger leads the proven sires at RZG 143 with a staggering +2,638 kg milk proof. But the real story is genomics: sires like Schach (RZG 161) and Evenstar (RZG 164) are pushing production and functional traits to new heights simultaneously. Germany’s focus on polled genetics is also paying off, with bulls like Create P offering elite merit without horns.

Holstein genetics, genomic testing, dairy profitability, herd improvement, German bull proofs

The German Holstein breeding landscape continues to demonstrate remarkable genetic advancement, with the August 2025 evaluations revealing exceptional bulls across both proven and genomic categories.

Daughter-Proven Excellence

The daughter-proven category is dominated by Zivet, who commands the rankings with an RZG of 147. This exceptional bull demonstrates remarkable balance, with production figures of +1,971 kg milk, +88 kg fat, and +86 kg protein. His functional trait profile is equally impressive, featuring a longevity score (RZN) of 121 and an overall health score (RZGes) of 113. With 422 daughters proven across 184 herds, Zivet‘s genetic merit is built on substantial reliability.

Following closely, Mirco maintains his position as a top-performing professional with an RZG of 144. His production profile shows +1,363 kg of milk, +65 kg of fat, and +59 kg of protein, combined with strong functional traits, including an RZN of 122 and excellent udder health scores.

Genomic Innovation

In the genomic sphere, Evenstar leads with an outstanding RZG of 164. This Real Syn son exhibits exceptional genetic potential, with projections of +2,090 kg of milk, +120 kg of fat, and +69 kg of protein. His balanced profile includes strong functional traits with an RZN of 134 and an RZGes of 109, positioning him as a premier choice for progressive breeding programs.

Matching the top spot is Pennywise, another genomic standout with an RZG of 164. This Picard son shows remarkable production potential (+1,761 kg milk, +124 kg fat, +76 kg protein) while maintaining an excellent balance of functional traits.

Red Holstein Distinction

The Red Holstein proven category showcases Ginger at the pinnacle with an RZG of 143. Proven through 510 daughters, this Gywer RDC son delivers a staggering +2,638 kg of milk, +85 kg of fat, and +90 kg of protein. His exceptional production is complemented by solid functional traits, including a longevity score (RZN) of 115.

Ghost Red emerges as another proven leader with an RZG of 139. His proof includes +1,904 kg of milk, but with a negative fat deviation, alongside a positive protein contribution, demonstrating the genetic diversity available within elite Red Holsteins.

Leading the genomic Red Holstein evaluation, Schach achieves an impressive RZG of 161. This Skat P RDC son represents the cutting edge of genomic selection, with production estimates of +1,910 kg milk, +98 kg fat, and +63 kg protein and a strong longevity potential (RZN 137).

Create P and Coco Red P both achieve an RZG of 161, demonstrating the depth of excellence in the Red Holstein population. Create P projects +1,291 kg milk, +65 kg fat, and +66 kg protein, while Coco Red P delivers +2,006 kg milk, +67 kg fat, and +80 kg protein.

Key Genetic Trends and Market Implications

The August 2025 evaluations highlight several key trends shaping the modern dairy industry. The emergence of genomic bulls like Evenstar and Pennywise with RZG values of 164 indicates that selection programs are successfully pushing the boundaries of genetic potential.

This genetic gain is directly translated to the milk tank. Production capabilities have reached new heights, with sires like the proven bull Ginger (+2,638 kg) and the genomic leader Evenstar (+2,090 kg) setting new benchmarks for milk yield while maintaining functional trait balance. This addresses the core need for profitable and productive cows.

Furthermore, these rankings reflect a clear response to market demands. In component-driven payment systems, the exceptional fat yields of bulls like Pennywise (+124 kg fat) are incredibly valuable. Simultaneously, the strong representation of polled genetics among top performers, such as Create P, offers producers a market-friendly solution to eliminate dehorning without sacrificing elite genetic merit.

Peak Spellbound-ET Surges to Top of Italian Genomic Rankings in August 2025 Evaluations

Tuesday, August 12th, 2025

Overdrive son crushes it while former leaders take a hit in August evaluations

Executive Summary: Italy just dropped their August genetic evaluations and Peak Spellbound-ET jumped to #1 with his impressive +1.07% fat and +0.54% protein, while former top dog Peak Vindicate-ET fell 20 points to second place. But here’s the kicker – Cookiecutter Hadley-ET went from #2 to #10, losing 102 points in one round. Meanwhile, the proven bulls? Rock steady. ZFZ Crisalis RF actually gained 29 points and strengthened his #1 proven position with that killer +1.95 udder composite. The Italians are obsessed with cheese production profits (their ICS-PR€ index), and guess what – the bulls ranking highest on both genomic and economic merit are the ones staying power. You want my advice? Start weighting proven performance heavier in your breeding decisions, especially with feed costs still brutal in 2025.

dairy cattle genetics, genomic sire selection, Holstein bull proofs, dairy breeding profitability, Italian genetic evaluations

The August Italian genetic evaluations just dropped, and honestly? The reshuffling is pretty dramatic. Peak Spellbound-ET came out of nowhere to grab the #1 spot among international genomic bulls with a gPFT of 5458. This Overdrive son is putting up some serious numbers – +1.07% fat and +0.54% protein – which explains why Italian cheesemakers are paying attention.

But here’s what’s really catching my eye: while the genomic bulls are bouncing around like ping-pong balls, the proven bulls are sitting pretty with much more stability. Makes you wonder if we’re getting a little too excited about these genomic predictions, doesn’t it?

Top 10 Foreign Genomic Bulls – August 2025

Peak Vindicate-ET, who was sitting pretty at #1 back in April, dropped to second place. Not a disaster by any means – he’s still at 5445 gPFT – but that’s a 20-point slide. This Samson son from Zemini bloodlines is still delivering solid milk production at 1628 kg with an impressive ICS-PR€ of 1385. The Italians love that cheese production index, and for good reason.

The real shocker? Cookiecutter Hadley-ET absolutely tanked from #2 in April all the way down to #10 in August. We’re talking about a 102-point drop here – from 5434 down to 5332. That’s the kind of volatility that should make any breeder nervous about putting all their eggs in one genomic basket.

What strikes me about these swings is how they contrast with the proven bull rankings. ZFZ Crisalis RF actually gained 29 points and strengthened his hold on the #1 proven spot. This Gywer son is showing what real daughter data looks like – +1.95 udder composite and solid type traits that actually hold up over time.

Top 10 Italian Proven Bulls – August 2025

The Overdrive Factor

Peak Spellbound’s rise to the top signals something interesting happening with the Overdrive bloodline in Italian programs. His ICS-PR€ of 1290 puts him right in the sweet spot for Italian dairy operations focused on cheese production. When you’re dealing with Parmigiano-Reggiano and Gorgonzola, those component percentages matter more than raw volume.

Peak Altasafezone-ET, another Overdrive son sitting at #6 with 5382 gPFT, is showing similar strengths. The economic merit on that bull is even stronger – ICS-PR€ of 1501. That’s the kind of number that gets Italian producers’ attention, especially with feed costs still brutal in 2025.

The thing about Overdrive genetics… they’re delivering this combination of components and economics that works really well for the Italian market. But I keep coming back to the volatility issue. These genomic predictions are jumping around based on relatively small daughter groups, while the proven bulls with thousands of daughters are showing much more consistency.

Proven Performance Tells a Different Story

While genomic bulls are doing their volatility dance, the proven rankings tell a more stable story. ZFZ Crisalis RF moved from 5140 to 5169 gPFT between April and August. That’s real improvement based on actual daughters in real herds.

Idevra Royal Inseme Carlomagno held steady at #2 with only a 3-point drop to 5062. This Bramante son continues putting up solid milk production numbers – 1539 kg – with the kind of consistency you want to see from proven genetics.

What’s particularly noteworthy is Isolabella Distefano ET jumping 43 points to secure #3 at 4948 gPFT. This Hothand son is showing exceptional type traits with a +2.93 udder composite. Those are the kind of numbers that translate to longevity in commercial herds.

The Economics Tell the Real Story

Here’s what I find fascinating about the Italian system – they’re putting serious weight on economic merit through their ICS-PR€ index. Smartie P-ET leads all bulls with matching IES€ and ICS-PR€ values of 1398. That kind of balance between total merit and cheese production profit is exactly what Italian operations need.

The proven bulls average around 800-900 ICS-PR€, while the top genomic bulls are pushing 1200-1400. Either the genomic predictions are overly optimistic, or we’re seeing some real genetic progress. Given the volatility we’re witnessing, I’m leaning toward the former.

Bloodline Diversification Continues

Owen, Samson, and Overdrive sons are all making strong showings in the top rankings. Danhof Calculus-ET and Progenesis Pellegrino, both Owen sons, are performing particularly well in milk production traits. The maternal grandsire diversity is providing some balance to these genetic packages, which is encouraging.

But here’s the thing – we’re seeing the same sire lines dominating across multiple countries. That concentration should make us nervous about long-term genetic diversity, especially when genomic predictions are driving so much of the selection pressure.

What This Means for Your Program

If you’re looking at these Italian evaluations for breeding decisions, here’s my take: Weight the proven performance much more heavily than these genomic predictions. Peak Spellbound might be #1 today, but will he still be there in December? The 102-point drop for Cookiecutter Hadley suggests probably not.

The proven bulls like ZFZ Crisalis RF are showing the kind of consistency that translates to profitable daughters. When you’re dealing with real farms, real feed costs, and real milk prices, that stability matters more than chasing the latest genomic superstar.

For Italian operations specifically, those ICS-PR€ numbers are critical. Don’t get distracted by flashy gPFT scores if the economic merit isn’t there. Cheese production profitability is what pays the bills, especially in today’s economic environment.

The volatility we’re seeing in these genomic rankings should be a wake-up call. We’re making multi-generational breeding decisions based on predictions that can swing 100+ points in a single evaluation. That’s not the foundation for sustainable genetic progress – it’s speculation.

Focus on proven performance, diversify your genetics, and remember that consistency often beats peak performance when you’re building a sustainable dairy operation.

Editorial Note: Following publication, ANAFIBJ Technical Coordinator Maurizio Marusi provided important statistical context regarding the evaluation changes highlighted in this article. Key technical clarifications include:

The correlation between April and August genomic evaluations was 99%, indicating high consistency in the underlying genetic predictions –  The standard deviation of the genomic gPFT index is 700 points, meaning the 100-point changes discussed represent approximately 1/7 of a standard deviation – well within normal statistical expectations for genomic evaluations –  The differential between genomic and proven bull averages in Italy (TOP 20 genomic: 1108-1325 ICS-PR vs. TOP 20 proven: 827-1067 ICS-PR) is comparable to similar differentials seen in other international systems, including the United States –  Ranking changes of 8 positions with minimal genetic value differences should be interpreted within the context of 75% reliability levels and the addition of competitive new bulls to the genomic pool

These statistical insights provide important context for interpreting genomic evaluation movements and underscore the importance of understanding the technical framework underlying these genetic predictions. We appreciate ANAFIBJ’s commitment to transparency and technical accuracy in their evaluation system.

Genetic Correlations Upended: Why Sticking with Old Breeding Indices Could Cost Your Dairy $486 Per Cow – And What the Data Really Proves

Tuesday, July 1st, 2025

April 2025 genetic reset proves TPI costs $486/cow. Feed Saved varies 900 lbs/lactation. Are you breeding for profit or pretty cows?

EXECUTIVE SUMMARY: The April 2025 genetic base change just shattered every assumption about Holstein breeding – and most producers are missing the $486 per cow profit opportunity hiding in plain sight. While PTAs dropped 650 pounds milk and 38 pounds fat overnight, this wasn’t genetic decline – it was proof of unprecedented advancement that’s making traditional TPI selection obsolete. Net Merit 2025 now predicts $486 more lifetime profit per cow than TPI, driven by butterfat emphasis jumping to 31.8% and Feed Saved evaluations ranging from -782 to +900 pounds per lactation. Research confirms every 1% increase in inbreeding costs 94.5 kg lifetime milk yield, while automated milking systems prove comparable economic performance to conventional parlors across 150-240 cow operations. Component-focused breeding aligns with market realities where butterfat commands $3.06/pound premiums and cheese manufacturing claims 90% of milk utilization. The evidence is overwhelming: producers clinging to conformation-heavy TPI are systematically breeding away from profitability while component-focused herds capture premium value in today’s market.

KEY TAKEAWAYS

  • Feed Efficiency Goldmine: Top bulls deliver 900-pound feed savings per lactation through Feed Saved genetics with 14% heritability – translating to measurable cost reductions for operations targeting efficiency over volume production.
  • Component Premium Capture: Net Merit 2025’s 31.8% butterfat weighting reflects real market premiums of $3.06/pound, positioning component-focused herds to capture significantly higher milk checks than volume-driven operations.
  • Technology ROI Validation: Australian AMS research proves comparable economic performance to conventional systems while milking 150-240 cows with 3-4 robotic units, freeing labor for high-value management tasks and achieving 19.3-26.3 kg daily production per cow.
  • Genetic Base Reality Check: The 650-pound milk PTA reduction represents genetic advancement, not decline – operations still using pre-2025 benchmarks are systematically undervaluing elite genetics and missing selection opportunities.
  • Inbreeding Cost Documentation: University research confirms every 1% inbreeding increase costs 94.5 kg lifetime milk yield plus extended calving intervals, making diverse genetic sourcing essential for maintaining production efficiency and reproductive performance.
dairy breeding indices, Holstein genetics profitability, feed efficiency genetics, component production dairy, automated milking systems

Are you still clinging to the “tall, pretty, high-volume” cow as your gold standard? It’s time to face the facts: the April 2025 genetic base change exposed conventional wisdom as a profit killer, not a profit driver.

The 2025 genetic base change shows the largest PTA milk adjustment (-752 lbs) in recent history, reflecting unprecedented genetic progress in Holstein dairy cattle over the past five years

The Pain Point: The Numbers Don’t Lie – But They Do Change

Let’s get real. The Council on Dairy Cattle Breeding’s (CDCB) April 2025 genetic base adjustment delivered significant changes, with Holstein PTAs dropping 650 lbs of milk, 38 lbs of fat, and 26 lbs of protein overnight – changes that were actually smaller than initially projected but still substantial. If you’re still benchmarking against pre-2025 numbers, you’re comparing apples to oranges – and leaving money on the table.

According to USDA’s May 2025 supply and demand report, U.S. milk production is projected at 227.3 billion pounds for 2025, with the all-milk price increased to $21.60 per hundredweight. But here’s the kicker: profitability is no longer about who ships the most milk but who ships the most value per cow.

Challenging a Sacred Cow: Is TPI Still Relevant for Commercial Profitability?

Net Merit’s 2025 formula emphasizes butterfat (31.8%) and feed efficiency (17.8%) far more than TPI’s conformation-heavy approach, reflecting current market realities where components command premium pricing

The Total Performance Index (TPI) has been the industry’s beauty contest for decades, rewarding conformation and stature. However, the latest data shows that TPI’s 26% conformation weighting is out of step with today’s economic realities. Net Merit (NM$) 2025 now predicts $486 more lifetime profit per cow than TPI – a gap confirmed by CDCB research.

The 2025 Net Merit revision reflects “enhanced commitment to dairy cattle genetic improvement and profitability through feed efficiency, component-based milk pricing, and fertility.” The formula puts 31.8% weight on butterfat and doubled emphasis on cow livability to 8.0%, reflecting what actually drives your milk check in today’s component-based markets.

Why does this matter? Because every dollar you spend chasing TPI points is a dollar not invested in traits that pay the bills, like butterfat, feed efficiency, and cow longevity.

The Feed Efficiency Revolution: Hard Numbers on Profit Impact

Feed efficiency genetics deliver the highest economic impact at $162 per cow annually, while strategic breeding decisions across multiple traits can add over $400 in total value per cow per year

Let’s talk feed. Feed accounts for over half of total dairy costs, so the Feed Saved trait delivers measurable results. In December 2020, “514,021 Holstein bulls received evaluations for Feed Saved, ranging from -782 to +900,” meaning daughters of the top bulls “are expected to consume 900 pounds less feed per lactation while maintaining similar production.”

Feed Saved has “a heritability of approximately 14%, which falls midrange relative to other traits,” according to the research. While reliability is currently lower than established traits – bulls averaging 30% reliability – the genetic potential is substantial.

Imagine two trucks hauling the same load – one gets 15 MPG, the other 12 MPG. Over a 100,000-mile lifespan, the efficient truck saves $2,500 in fuel. Now scale that to your herd: genetic efficiency measured through Feed Saved represents the difference between breaking even and banking profit.

Inbreeding: The Silent Profit Killer with Documented Losses

Here’s the controversial truth backed by research: Holstein inbreeding effects are measurable and costly. University of Wisconsin research documents that “for each 1% increase in inbreeding, lifetime total milk yield decreased by 94.5 kg, lifetime total fat yield decreased by 3.3 kg, and lifetime total protein yield decreased by 2.9 kg.”

The reproductive impacts are equally concerning: research shows “a 0.7-d increase in calving interval and a 0.3% decrease in survival to second lactation per 1% increase in inbreeding.” USDA scientist Paul Cole explains that “when inbreeding levels rise, we’re more likely to pair two undesirable copies of a gene in the same location,” affecting fertility, longevity, and disease resistance.

Economic impact is measurable: With documented production losses and extended calving intervals, every percentage point of inbreeding represents significant lifetime profit reduction through both decreased output and increased replacement costs.

Technology in Action: Precision Genetics and Automation Delivering Results

The genetic changes aren’t happening in isolation – they’re accelerated by technology adoption proving its worth globally. NSW Department of Primary Industries research confirms that automated milking systems “deliver comparable performance to conventional systems.”

Key AMS findings from Australia:

  • Farms typically milk 150-240 cows with 3-4 robotic units
  • Daily milk production per cow ranges from 19.3 to 26.3 kilograms
  • Cows are milked an average of 2.17 times per day
  • Each robot harvests approximately 1,200 kg of milk daily

The research reveals that “AMS is beneficial for freeing up labour for other key tasks such as pasture management, boosting overall farm productivity.” This labor reallocation enables farmers to focus on “farm business management, herd health, and pasture management, enhancing overall farm efficiency and sustainability.”

The Global Market Reality: Components Command the Premium

Market analysis confirms that “butterfat will lead the way for the third straight year in multiple component pricing markets, which price over 90% of the nation’s milk.” In November 2024, “butterfat brought $3.06 per pound and protein was $2.32.”

Global market trends support component focus:

  • International butter and cheese prices are stronger than U.S. levels
  • Fonterra lifted the 2024-2025 milk price forecast to $10 midpoint per kilogram of milk solids
  • U.S. dairy consumption reached 661 pounds per capita in 2023
  • Cheese consumption hit a record 40.5 pounds per person

With USDA forecasting the 2025 all-milk price at $21.60 per cwt, component-focused herds are positioned to capture premium value as cheese manufacturing continues dominating milk utilization.

Why This Matters for Your Operation

  • Verified Genetic Progress: The April 2025 base change confirms substantial genetic advancement, with CDCB calculations showing “a 0.992 correlation between the April 2025 and current formulas, indicating little reranking expected for most animals.”
  • Feed Efficiency Impact: Top bulls can save 900 pounds of feed per lactation while maintaining production levels
  • Technology Advantage: AMS systems prove comparable economic performance while freeing labor for value-added management tasks
  • Market Alignment: Component emphasis in NM$ 2025 reflects real market premiums driving profitability

Implementation Timeline and Practical Steps

  • Feed Efficiency Focus: Target bulls with positive Feed Saved evaluations, recognizing the 14% heritability enables genetic progress
  • Component Selection: Leverage the 31.8% butterfat emphasis in NM$ 2025 to capture market premiums
  • Technology Integration: Consider AMS adoption where labor flexibility and management focus provide competitive advantages

Barriers and Solutions

  • Inbreeding Management: Use diverse genetic sources and monitor Expected Future Inbreeding levels, given documented production losses per percentage point increase
  • Technology Adoption: AMS research shows “over 50,000 systems now in use worldwide” with Australia implementing on “around 1.5% of dairy farms, with growing interest”
  • Market Adaptation: Align breeding programs with component-focused payment systems that price over 90% of national milk production

Rhetorical Reality Checks

  • Are you still benchmarking your herd’s genetic progress against pre-2025 standards when CDCB confirms the largest genetic advancement in recent history?
  • How many of your breeding decisions account for the documented $3.06/pound butterfat premiums driving component-focused markets?
  • Is your operation positioned to capture the labor flexibility advantages that AMS research proves comparable to conventional systems?

The Bottom Line: What the Verified Data Proves

The 2025 genetic base change confirms unprecedented genetic progress, with PTAs dropping 650 pounds of milk, 38 pounds of fat, and 26 pounds of protein – yet these reductions were smaller than expected, indicating even greater genetic advancement than initially projected.

The economics are clear: Net Merit 2025 predicts $486 more lifetime profit per cow than TPI, while Feed Saved evaluations ranging from -782 to +900 pounds per lactation represent tangible feed cost differences. Component-focused breeding aligns with market realities where butterfat commands $3.06/pound premiums.

Your next steps – backed by verified research:

  1. Recalibrate benchmarks using the April 2025 genetic base, recognizing that apparent PTA reductions reflect genetic progress, not losses
  2. Prioritize Feed Saved genetics with their documented 14% heritability and 900-pound feed savings potential
  3. Leverage component emphasis as NM$ 2025’s 31.8% butterfat weighting reflects real market premiums
  4. Evaluate AMS technology where research proves comparable economic performance with enhanced labor flexibility
  5. Monitor inbreeding levels given documented production losses of 94.5 kg of milk per 1% increase

Ready to capitalize on genetic advancement? The data confirms that strategic breeding delivers measurable results, component markets reward focused genetics, and technology adoption provides competitive advantages. The only question: will you lead with evidence-based breeding strategies or lag using outdated benchmarks?

EXECUTIVE SUMMARY: The May 2025 analysis of high-GTPI Holstein females highlights OCD THORSON RIPCORD-ET as the premier sire, with 12 daughters averaging 3492 GTPI – the highest genetic merit transmission. PEAK ALTAMAKEOVER-ET dominates representation (24 daughters), reflecting reliable trait transmission. Key trends include a 463-point feed efficiency ceiling, sustained health trait improvements (SCS ≤3.0 in 78% of elites), and strategic emphasis on moderate-sized, high-component producers. While 62% of the top 50 females trace to just five sires, emerging lines like GENOSOURCE ENDURANCE-ET show promise with single-daughter excellence. The data underscores industry success in balancing production gains with functional longevity metrics.

KEY TAKEAWAYS:

  • Sire Supremacy: OCD THORSON RIPCORD-ET delivers both quality (3492 avg GTPI) and quantity (12 daughters), outperforming higher-volume sires
  • Efficiency Revolution: Feed efficiency scores reach 463 (+35% vs 2024 benchmarks), prioritizing sustainable production
  • Health-First Breeding: 82% of top females maintain sub-3.0 SCS alongside positive fertility indexes, defying historical yield-health tradeoffs
  • Genetic Concentration Risk: 58% of elite genomic females originate from 3 sire lines, necessitating proactive diversity management
  • Component Optimization: Fat yield leads genetic progress (+153 lbs PTAF in top animal) while maintaining protein percentages

The May 2025 list of high-ranking genomic Holstein females showcases the elite genetic potential in the dairy industry. This analysis examines the key sires influencing these top genomic females and identifies important genetic trends that can guide breeding decisions. The data reveal distinct patterns in sire representation, genetic merit, and trait profiles that warrant attention from progressive dairy producers.

Top Individual Performers

The elite genomic females in May 2025 demonstrate exceptional genetic merit, with GTPI values reaching as high as 3623. The top individual, OCD RIPCORD ZENITH-ET (GTPI 3623), exemplifies the remarkable genetic potential available through modern genomic selection. This heifer combines outstanding production potential (PTAP 70, PTAF 153) with impressive feed efficiency (463) while maintaining favorable health traits.

Among the top five genomic females, we observe the significant influence of two particular sires: OCD THORSON RIPCORD-ET and PEAK ALTAMAKEOVER-ET, each with two daughters in this elite group. S-S-I ROSEMARY 6127 9344-ET (GTPI 3603) stands out with a balanced profile featuring strong health and fertility traits, while demonstrating exceptional udder conformation (UDC 1.41).

The top genomic females consistently display above-average values for production traits while maintaining favorable health and fertility traits. This suggests successful selection for balanced breeding that avoids sacrificing functional traits for production potential.

Sire Influence Analysis

Dominant Sires by Daughter Count

The distribution of sires represented in this elite genomic list provides valuable insights into genetic influence within the Holstein breed. The data reveals several key sires with substantial impact:

  1. PEAK ALTAMAKEOVER-ET leads with 24 daughters averaging 3443.5 GTPI, demonstrating both prolific representation and high genetic merit.
  2. PEN-COL WHOOPS-ET follows with 20 daughters averaging 3407.7 GTPI.
  3. S-S-I SHEEPSTER MICAN-ET contributes 19 daughters with an average GTPI of 3430.2, showing strong consistency in genetic transmission.
  4. BERRYRIDGE SSI KARL-ET has 16 daughters averaging 3414.6 GTPI.

This distribution pattern indicates that certain genetic lines are disproportionately contributing to the elite tier of the Holstein population. The consistent performance of daughters from these sires suggests reliable genetic transmission for key economic traits.

Exceptional Genetic Merit Transmission

When examining sires based on their daughters’ average GTPI values, a different hierarchy emerges:

  1. OCD THORSON RIPCORD-ET stands out with 12 daughters averaging an exceptional 3492.3 GTPI, positioning it as an elite genetic transmitter.
  2. GENOSOURCE ENDURANCE-ET shows promise with one daughter at 3492.0 GTPI, though sample size limits definitive conclusions.
  3. PEAK PRIMERO-ET demonstrates high genetic merit with two daughters averaging 3473.5 GTPI.

OCD THORSON RIPCORD-ET deserves particular attention as it achieves both significant representation (12 daughters) and the highest average GTPI. This combination of quantity and quality suggests it may be an especially valuable sire for breeding programs focused on genetic advancement.

Statistical Performance Analysis

The overall GTPI statistics provide context for evaluating these elite females:

  • Mean GTPI: 3427.4
  • Median GTPI: 3415.0
  • Standard deviation: 41.8
  • Maximum GTPI: 3623.0
  • Minimum GTPI: 3381.0

The threshold for “high achiever” sires (mean + 1 standard deviation) was calculated at 3469.2 GTPI. Only three sires had daughters averaging above this threshold: OCD THORSON RIPCORD-ET, GENOSOURCE ENDURANCE-ET, and PEAK PRIMERO-ET, highlighting their exceptional genetic contribution.

Key Trait Patterns

Production Traits

The elite genomic females demonstrate strong production genetics, particularly for fat yield. Many top individuals show PTAF values exceeding 120 pounds, with the highest reaching 153 pounds (OCD RIPCORD ZENITH-ET). This reflects the industry’s continued emphasis on component production, especially fat yield and percentage.

Interestingly, these high-ranking females maintain relatively balanced component profiles. The top heifers show positive protein and fat percentage values, indicating selection pressure for improved component production without sacrificing volume. This aligns with milk pricing systems that reward component-rich milk.

Feed Efficiency and Health Traits

A notable trend is the emphasis on feed efficiency, with most top individuals showing feed efficiency values above 300, and elite animals exceeding 400. This reflects the industry’s growing focus on efficiency metrics as feed costs represent a significant expense in dairy operations.

Health and fertility traits show positive trends among these elite females. The Health Trait index values are predominantly positive, with many top individuals showing values above 5.0, indicating robust genetic potential for disease resistance. Somatic Cell Score values generally fall below 3.0, suggesting strong genetic resistance to mastitis.

Conformation Traits

The elite genomic females show moderate emphasis on conformation traits. While PTAT values vary considerably, there’s a clear preference for positive udder composite (UDC) values, with many top individuals exceeding 1.0. This reflects the continued importance of udder structure for longevity and functional productivity.

Body Weight Composite (BWC) values trend negatively among many top individuals, suggesting selection pressure toward moderate-sized, efficient animals rather than larger-framed individuals. This aligns with industry movement toward efficiency and sustainability.

Emerging Breeding Trends

Several important breeding trends emerge from the analysis of this elite group:

  1. Balanced Selection Emphasis: The top genomic females demonstrate balanced genetic profiles rather than extreme values in single traits. This suggests successful implementation of selection indices that properly weight economic importance across multiple traits.
  2. Efficiency Focus: Strong feed efficiency values and moderate body size indicate increased selection pressure for efficient production systems that maximize output while minimizing inputs.
  3. Sire Line Concentration: The influence of a relatively small number of elite sires suggests potential narrowing of the genetic base at the highest levels. While this accelerates genetic progress, it warrants monitoring for inbreeding management.
  4. Health and Fertility Maintenance: Despite strong production genetics, these elite females maintain favorable health and fertility values, demonstrating successful selection for comprehensive economic merit rather than production alone.

The Bottom Line

The May 2025 high-ranking genomic Holstein females showcase remarkable genetic progress and provide valuable insights for breeding decisions. OCD THORSON RIPCORD-ET emerges as a particularly influential sire, combining significant daughter representation and exceptional average genetic merit. PEAK ALTAMAKEOVER-ET demonstrates impressive prolificacy with the most daughters in the elite group.

For dairy producers seeking genetic advancement, these data suggest several strategic approaches:

  1. Consider daughters of proven elite sires like OCD THORSON RIPCORD-ET and PEAK ALTAMAKEOVER-ET for potential breeding stock.
  2. Monitor emerging sires with limited but promising daughters, such as GENOSOURCE ENDURANCE-ET.
  3. Focus selection on balanced traits that maintain health and fertility while advancing production and efficiency.
  4. Implement inbreeding management strategies as the genetic base narrows at elite levels.

This analysis demonstrates the remarkable genetic potential available through genomic selection while highlighting the importance of balanced trait selection for sustainable genetic advancement in Holstein breeding programs.

This recalibration represents a statistical reset rather than a genetic potential reduction.

Comparing specific bulls highlights the magnitude of these changes. GENOSOURCE CAPTAIN-ET maintained his elite status with a TPI of 3441G (up from 3336 in December), yet his milk production value decreased from 2542 to 1872 (-670 pounds). Similarly, his PTAT dropped from 1.11 to 0.28, UDC from 1.65 to 0.83, and Productive Life from 5.0 to 3.7. These adjustments reflect the new genetic baseline rather than diminished capabilities.

The base change emphasizes more balanced trait profiles than individual categories’ extremes. Most notably, some bulls maintained or improved their rankings despite these numerical adjustments, while others experienced significant position changes despite gaining absolute TPI points.

GTPI Leaders: Elite Bulls Maintain Dominance

The genomic TPI rankings show remarkable stability at the top despite the base change. RIPCORD leads with an impressive 3537 TPI, maintaining his December 2024 #1 position. He’s followed closely by ABAY (3526), JZ (3506), DARTH VADR (3504), and WATCHMAN (3499).

These elite bulls showcase exceptional genetic balance across all trait categories:

  • RIPCORD combines outstanding milk production (1496) with excellent fat (126) and protein (62) values
  • ABAY excels in component percentages with 0.34% fat and 0.11% protein
  • DARTH VADR stands out with the highest milk production (2228) among the top TPI bulls
  • WATCHMAN balances strong production with exceptional health traits (Health Index: 8.7)

On the proven side, GENOSOURCE CAPTAIN-ET maintains its #1 position with 3441G TPI, followed by SDG CAP GARZA-ET at 3418. STGEN COWEN THORSON-ET emerged at #3 with 3389, demonstrating the continued strength of established bloodlines.

Net Merit Champions: Economic Efficiency Leaders

DARTH VADR tops the Net Merit rankings at $1270 for commercial producers focused on profitability, followed by RIPCORD ($1239) and ENDURANCE ($1222). These economic powerhouses combine exceptional production with strong health traits:

  • DARTH VADR’s outstanding milk production (2228) comes with excellent component values (145 fat, 69 protein)
  • ENDURANCE offers superior component percentages (0.35% fat) while maintaining solid milk production
  • RIPCORD demonstrates exceptional balance with a Productive Life of 4.5 and a Fertility Index of 1.7

The top Net Merit bulls correlate strongly with high TPI values, indicating that economic efficiency and overall genetic merit align well in the April 2025 evaluations.

Type Specialists: Conformation Excellence

Breeders emphasizing conformation will find STORY ARC leading with a remarkable 3.88 PTAT, followed by SHG LEGO (3.83) and ADMIRE (3.71). These conformation specialists generally show:

  • Exceptional udder composite scores, with STORY ARC at 2.74 UDC
  • Strong feet and leg composites, with SHG LEGO at 2.22 FLC
  • Lower TPI and Net Merit values compared to production leaders

For breeders seeking a balance between type and economics, STARPOWER RC offers an excellent compromise, with a PTAT of 3.08 while maintaining a competitive TPI (3137) and positive Net Merit ($445). PALDWYN (TPI: 3085, PTAT: 3.12) provides another strong option, combining type with overall genetic merit.

Red & White Genetics: Colored Genetics Advance

The Red & White segment continues its rapid advancement with several bulls exceeding 3200 TPI. Papaya-Red leads with a TPI of 3285 and exceptional type values (1.99), followed by Morris-Red (3216 TPI, $1005 Net Merit) and Pegasus-Red (3162 TPI).

Key strengths among the R&W leaders include:

  • Morris-Red’s impressive milk production (1499) and strong Net Merit ($1005)
  • Pegasus-Red’s exceptional health traits (Health Index 9.4)
  • Parbie-Red’s balanced profile (TPI 3144) with strong type (1.63)

The top Red & White bulls demonstrate that colored genetics no longer require sacrificing genetic merit, with several bulls approaching the performance of the mainstream black and white leaders.

Notable Movements and Newcomers

The April 2025 evaluations brought several significant ranking changes and new entrants:

  • ABAY and JZ debuted near the top of the GTPI list with 3526 and 3506 TPI, respectively
  • GENOSOURCE CAP LEVOY-ET entered the top 10 at #9 (3257)
  • RMD-DOTTERER SSI GAMEDAY-ET TR climbed into the top 10 (3253)
  • PLAIN-KNOLL RENEGAD TROOPER TR dropped from #3 to #8 despite gaining 75 TPI points
  • GENOSOURCE CAPN MCGUIRE-ET TE fell dramatically from #5 to #43 (3160)
  • DELICIOUS H-NOON TAMPA-ET TR TE dropped from #9 to #49 (3153)

Several newcomers in the Red & White category made impressive debuts, including Papaya-Red and Parbie-Red, demonstrating continued progress in red genetics.

Genetic Diversity Considerations

The April 2025 list reveals significant concentration within certain sire lines, with multiple “CAP” prefix bulls (CAPTAIN sons) occupying top positions. This concentration demonstrates the rapid genetic progress possible with genomic selection but raises potential inbreeding concerns.

Similarly, the prevalence of RIPCORD, DARTH VADR, and other elite sires across multiple categories indicates a concentration of genetic influence. While these bulls offer exceptional genetic merit, their widespread use could decrease genetic diversity if not managed carefully.

Practical Recommendations for Breeders

Understanding the Base Change

The base change adjustment has recalibrated all genetic values to reflect current population genetics. When comparing April 2025 values to previous evaluations, remember that numerical differences are largely due to this statistical reset rather than accurate genetic shifts. Focus on relative rankings rather than absolute numbers.

Recalibrating Selection Thresholds

If you previously selected bulls above specific minimum values (e.g., Net Merit > $1000), adjust these thresholds to account for the base change. Consider using percentile ranks rather than absolute values when making selections.

Balanced Trait Selection

The April 2025 evaluations favor bulls with more balanced genetic profiles. RIPCORD and DARTH VADR exemplify this balance with high values across production, health, and conformation categories. Consider using selection indexes that match your operation’s specific goals rather than focusing on individual traits.

Managing Genetic Diversity

Maintaining genetic diversity is crucial, especially with a significant concentration in certain sire lines. Consider using bulls from diverse genetic backgrounds when appropriate, and utilize inbreeding management tools available through your genetic supplier. Red carrier bulls can introduce genetic diversity and the red gene into your herd.

Looking Beyond Numbers

While genetic evaluations provide valuable data, consider other factors like daughter performance, reliability, and genetic diversity in your breeding decisions. Consult with genetic advisors to interpret the new evaluations in the context of your specific breeding objectives.

The Bottom Line

The April 2025 Holstein evaluations represent a significant recalibration through the implementation of a new genetic base. While numerical changes may initially seem confusing, they provide a more accurate reflection of current genetic levels in the Holstein population.

Despite these adjustments, elite bulls maintain their positions of prominence, with RIPCORD, DARTH VADR, ABAY, and JZ leading the way. The emergence of new talent and continued progress in red genetics provide exciting opportunities for breeders to advance their herds.

By understanding the base change impact and focusing on relative rankings rather than absolute values, dairy producers can effectively navigate these changes and continue making genetic progress in production efficiency, health, and conformation. As always, balance selection decisions with specific breeding goals to maximize the benefits of these new evaluations.

April 2025 Sire Evaluations: Scandinavian Holstein Rankings Reveal New Leaders

Tuesday, April 1st, 2025

The April 2025 genetic evaluations for Scandinavian Holstein bulls have been released, showcasing significant movements in both proven and genomic sire categories. This evaluation period brings several notable changes to the Nordic Total Merit (NTM) rankings, with emerging stars and consistent performers shaping the landscape of Holstein genetics.

Proven Sire Rankings

PEAK RAINOW-ET has solidified his position at the top of the proven sire list with an impressive NTM of 38, showing continued improvement from his December 2024 evaluation. His exceptional profile combines high milk yield (+127) with outstanding daughter fertility (+119) and strong udder health (+99), making him a balanced choice for breeders focused on both production and fitness traits.

The episode has emerged as a newcomer to the elite rankings, securing the second position with an NTM of 35. His exceptional yield scores (+138), coupled with good growth (+115) and solid general health (+109), demonstrate the continued emphasis on production efficiency in the Scandinavian breeding program.

Metro rounds out the top three proven sires with an NTM of 30. Although his December evaluation showed a slight decline, he maintained strong yield (+133) and good udder health (+106) metrics.

Genomic Sire Highlights

In the genomic rankings, VH Crown leads the pack with an outstanding NTM of 42. This showcases exceptional milk yield potential (+145) combined with strong fertility (+121) and robust longevity (+112). This represents a 2-point improvement since the December evaluations, further cementing his position as the genomic leader.

GAGA-ET follows in second place with an NTM of 40, demonstrating particular strength in protein yield (+125) along with good udder health (+110) and productive life (+108) scores.

VH Gatsby completes the top three genomic sires with an NTM of 39, offering breeders a balanced profile with strong conformation traits and fertility improvements.

Emerging Trends

The April 2025 evaluations highlight several key trends in Scandinavian Holstein breeding:

  1. Production traits dominate the rankings, with exceptional milk yield scores becoming increasingly common among top bulls. Many leading sires show yield scores above +125, reflecting the industry’s continued focus on production efficiency.
  2. Fertility remains a critical selection criterion, with top bulls like PEAK RAINOW-ET (+119) and VH Crown (+121) demonstrating that high production can be achieved without sacrificing reproductive performance.
  3. Genomic reliability values show steady improvement, with reliability scores averaging above 70%, indicating increased confidence in genomic predictions for future performance.
  4. The gap between proven and genomic evaluations continues to narrow, with genomic sires like VH Crown showing NTM values that exceed even the top proven bulls by 4 points.

As dairy producers analyze these April 2025 evaluations, the data suggests a continued emphasis on balanced breeding goals that combine production efficiency with functional traits. The strong performance of newcomers and established sires indicates healthy genetic progress in the Scandinavian Holstein population.

Genetic Revolution: How Record-Breaking Milk Components Are Reshaping Dairy’s Future

Thursday, March 27th, 2025

U.S. dairy’s genetic revolution: Butterfat & protein smash century-old records as genomics redefine milk’s DNA. Are your herds future-ready?

The U.S. dairy industry is experiencing an unprecedented transformation as genetic improvements drive historic gains in milk components. While milk production remains flat, butterfat and protein levels are climbing at record rates, creating extraordinary value for producers and processors alike. This genetic revolution is perfectly timed to meet growing demand as $8 billion in new processing capacity comes online through 2027.

The Component Surge: Breaking Records at Breakneck Speed

The numbers tell a compelling story that every dairy producer should consider. Butterfat has posted its fourth consecutive annual record when evaluating data over a century. In 2021, milkfat broke through the symbolic 4% ceiling, surpassing a record that had stood since the end of World War II. By 2024, butterfat levels charged even higher to average 4.23% nationally.

Protein hasn’t been left behind, with new consecutive yearly records posted from 2016 to 2024. The 2024 milk marketing year finished with an average protein content of 3.29%—a remarkable jump from the 3.04% level recorded just two decades ago in 2004.

These gains are particularly noteworthy because they’ve decoupled from overall milk volume trends. From 2001 to 2010, milk volume, butterfat, and protein production improved at similar rates, ranging from 13.8% to 15.4%. Since then, however, the metrics have diverged dramatically:

Production MetricGrowth 2011-2024
Milk Volume15.9%
Protein23.6%
Butterfat30.2%

This divergence is occurring at a critical moment, as U.S. milk production has stalled. The country experienced its first back-to-back years of declining production since the 1960s, with output falling by -0.04% and -0.23% in 2023 and 2024, respectively, following minimal growth of 0.07% in 2022.

The Genomic Game-Changer: How DNA Testing Revolutionized Breeding

The driving force behind this component revolution is unquestionably genomics—a technology that has fundamentally altered dairy cattle breeding. Genomic testing allows producers to compare an individual animal’s DNA to the overall population, revealing about 70% of a young calf’s genetic potential before she matures into a cow.

“The dairy cow has become the most studied domestic animal on the planet,” explains Dr. John Cole, research lead at USDA-AGIL. “Humans and laboratory mice are the only species with larger genetic datasets than dairy cows. However, those species don’t have a comprehensive phenotypic dataset in dairy cattle. That dataset drives accuracy for genomic predictions.”

The adoption of genomic testing has grown exponentially since its introduction. After the technology was released to the dairy industry in 2009, it took seven years to genotype the first million dairy males and females. As producer confidence in the system grew, testing ramped up dramatically—the industry reached 5 million tests by March 2021 and surpassed the 10 million mark in December 2024. 66% of these tests have been conducted on U.S. dairy cattle, with the remaining 34% from 72 other countries.

This widespread adoption of genomic testing has fundamentally altered the balance between genetics and management as drivers of production improvements:

  • 1957-1980s: Management factors (nutrition, housing, health) were the primary force behind productivity gains
  • 1980-2000: Management and genetics contributed roughly equally to production improvements
  • 2000-2009: Genetics began overtaking management as the primary driver
  • 2015: Genetics contributed over 60% to improvements in milk production
  • 2022: Genetics accounted for over 70% of production gains

The April 2025 Genetic Reset: What Every Producer Needs to Know

The U.S. dairy industry will experience its most significant genetic recalibration in decades. On April 1, 2025, the Council on Dairy Cattle Breeding (CDCB) will implement simultaneous updates to lifetime merit indices and shift all genetic evaluations to a 2020-born cow base.

This dual adjustment—the first combined overhaul since 2015—aims to reflect the 28% faster genetic progress in key traits while aligning economic weightings with today’s market realities and sustainability pressures.

Resetting the Genetic Compass

CDCB adjusts its genetic evaluations every five years to account for industry progress—comparable to upgrading a smartphone’s operating system. The 2025 shift compares all animals against cows born in 2020 rather than 2015, creating these projected PTA adjustments:

TraitHolsteinJerseyAyrshire
Milk (lbs)-750-380-550
Fat (lbs)-45-20-28
Protein (lbs)-30-15-18

“Think of it like resetting an odometer after driving 100,000 miles,” explains Dr. Cole. “The numbers get smaller, but the vehicle’s capability hasn’t changed.”

One can examine the pace of genetic base changes to appreciate the scale of genetic improvement. In 2025, the Holstein base will roll back 51 pounds for butterfat and 36 pounds for protein. This represents a dramatic acceleration compared to earlier periods—in 2015, the Holstein base rolled back just 17 pounds for butterfat and 12 pounds for protein.

The Jersey breed, which, along with Holsteins and their crosses, makes up over 95% of the U.S. dairy cow population, has shown similar genetic progress. The April 2025 genetic evaluations reveal a 20-pound base change for butterfat and a 15-pound rollback for protein in Jerseys.

Merit Index Overhaul

Simultaneously, the revised Net Merit $ (NM$) formula now prioritizes:

  • Butterfat (↑13% weighting): Reflects cheese demand driving fat prices to $3.20/lb
  • Feed Efficiency (↑41% combined impact): Addresses $300/ton feed costs
  • Livability (↑100%): Responds to cull values exceeding $1,800/head

“We’re essentially giving fertility traits a 20% promotion and putting milk volume on performance improvement plans,” notes CDCB Chair Amy Hazel.

The updated Lifetime Merit Indices include adjustments to the economic weights of individual traits, with an increased emphasis on feed efficiency, milk component pricing, and fertility. For instance, the weight for fat in NM$ has increased from 28.6 to 31.8, while the weight for protein decreased from 19.6 to 13. These changes reflect evolving market demands and research advancements.

Regional Strategies: How Different Dairy Areas Are Leveraging Genetics

The genetic revolution has played out differently across America’s dairy landscape, with distinct regional approaches to production improvement. Economists have identified notable differences between “traditional” dairy states in the Midwest and Northeast, with small herd sizes and a long history of dairy production, and “modern” dairy states, primarily in the West, with large herds where the dairy sector has only recently reached its current scale.

Traditional vs. Modern Production Approaches

While each region contributes roughly equal shares to total U.S. milk production, their growth strategies differ. Traditional dairy states have focused primarily on increasing milk yield through genetic and management improvements. In contrast, modern dairy states have grown production by increasing milk yield and total cow numbers.

The contrast in herd size is stark—Western states have substantially larger herds, with nearly all averaging above 1,000 cows per operation. Traditional dairy states in the Midwest and Northeast have much smaller herds but have been catching up in productivity. In 2000, modern dairy states had a significant yield advantage of 1,721 pounds per cow versus 1,473 pounds in traditional states. By 2022, this gap had narrowed to less than 100 pounds (2,070 versus 1,984 pounds per cow).

Convergence in Yield Improvement

This convergence in productivity coincides with the introduction of genomic testing, suggesting that traditional dairy states have embraced genetics as their primary growth strategy. Unable to expand cow numbers due to land constraints, zoning regulations, and environmental concerns, these states have invested heavily in genetics, enhanced milking technology, and improved management practices.

As cow numbers across the country begin to level off, modern dairy states may follow the lead of traditional regions by focusing more intensively on yield improvements rather than herd expansion. This mirrors a broader trend in U.S. agriculture, where productivity gains increasingly drive output growth rather than expanding production areas.

The Economics of Components: Why This Matters to Your Bottom Line

The shift toward higher-component milk is creating significant economic value throughout the dairy supply chain. With over 80% of the U.S. milk supply going into manufactured dairy products that rely on butterfat and protein content, these genetic gains are perfectly aligned with market demands.

“Selecting animals for highly heritable traits and having a market incentive to do so has formed a strong foundation for dairy producers to develop their herds to produce more butterfat and protein.”

The U.S. milk pricing system, which pays premiums for components, has created powerful incentives for producers to select for these traits. These market signals have spurred innovations in breeding technology beyond genomic testing:

  • Gender-sorted semen: By 2024, 61% of all dairy semen sold in the U.S. came from this category, giving rise to the strategy described by some farmers as “sexed semen on the best and beef semen on the rest.”
  • Embryo technology: More recently, dairy farmers have begun creating conventional and in vitro fertilized embryos from elite females, further accelerating genetic progress

The surge in milk components comes at a strategic time for the industry, with $8 billion in new dairy processing capacity scheduled to come online through 2027. This expansion heavily focuses on cheese, butter, and other manufactured products that yield from components rather than fluid volume.

Accelerating Technologies: What’s Driving the Next Wave of Genetic Progress

The 2025 genetic reset paves the way for even more advanced selection tools:

  • Rumen Microbiome PTAs (expected by 2028): Linking microbial profiles to feed conversion efficiency
  • Methane Emission Indexes: Responding to potential EPA enteric fermentation regulations
  • Heat Tolerance Updates: Critical as 73% of U.S. counties face higher heat stress days

These emerging technologies will further enhance producers’ ability to select economically important traits while addressing sustainability concerns.

The Bottom Line: Positioning Your Herd for Future Success

April’s genetic overhaul serves as both a progress report and crystal ball—validating two decades of genomic advances while redirecting selection pressure toward tomorrow’s profitability drivers. As dairy economist Chris Wolf notes, “The cows we’ll milk in 2035 are being designed today through these evaluations.”

Producers who realign breeding strategies with NM$ 2025’s economic reality—where every 1 lb of fat equals 2.3 kg of protein in revenue—position themselves to thrive in dairy’s next era. Here’s what forward-thinking producers should consider:

  1. Recalibrate sire selection thresholds: What was once +2000 NM$ becomes approximately +1300 NM$ after the base change
  2. Focus on component ratios: The economic value of fat relative to protein continues to increase
  3. Prioritize feed efficiency: With high feed costs, efficient feed conversion to components becomes increasingly important.
  4. Don’t ignore fertility and health traits: The revised indices emphasize these economically important traits.

The question of how high butterfat and protein percentages can ultimately go remains open. Industry experts believe there is still untapped potential as dairy farmers continue to leverage genetics programs to select component traits.

The genetic revolution in U.S. dairy production represents one of the most successful applications of genomic science in agriculture. Unprecedented gains in milk components are transforming dairy production and processing economics, creating new opportunities throughout the supply chain. While milk volume has plateaued, the continued improvements in butterfat and protein composition ensure the industry can meet the growing demand for manufactured dairy products.

As genomic testing becomes even more widespread and breeding strategies continue to evolve, the U.S. dairy industry is positioned to maintain its leadership in genetic improvement. Whether through traditional family farms in the Midwest focusing on component yield or large Western operations balancing yield and scale, producers across the country are embracing genetics as the key to future profitability and sustainability in an increasingly competitive global dairy market.

The dairy industry’s genetic revolution is far from over—it’s just getting started.

KEY TAKEAWAYS:

  • Component production now outpaces milk volume (+30% butterfat growth vs. +16% milk since 2011)
  • Genomics drive 70% of gains – 10M cattle tested globally, transforming breeding decisions
  • 2025 genetic reset prioritizes feed efficiency (+41% weighting) and fat value ($3.20/lb market reality)
  • Regional strategies diverge: Small herds optimize genetics, large operations balance yield + scale
  • Emerging tools (rumen microbiome PTAs, methane indexes) will shape 2030s’ herds

EXECUTIVE SUMMARY:

The U.S. dairy industry is achieving unprecedented butterfat (4.23%) and protein (3.29%) levels through genomic breakthroughs, with genetics now driving 70% of production gains. As milk volumes stagnate, component-focused breeding strategies align perfectly with $8B in new processing capacity for cheese and butter. The 2025 genetic base reset accelerates progress, while regional approaches (traditional herds optimizing yield vs. modern operations balancing scale) showcase adaptation. With feed efficiency and sustainability traits gaining priority in updated merit indices, producers leveraging advanced technologies like sexed semen and embryo transfer position themselves to capitalize on dairy’s component-driven future.

EXCLUSIVE: Three Bull Lines Dominate 33% of Elite Holstein Genomics – March 2025 GTPI Rankings Reveal Genetic Bottleneck

Sunday, March 16th, 2025

Just 5 sires control half the elite Holstein gene pool. Is the rush for higher GTPI numbers creating a genetic time bomb? The numbers don’t lie.

Executive Summary

The March 2025 genomic rankings reveal an alarming concentration of genetic influence with just 33% of elite Holstein females traced to only two bulls (KARL and ALTAMAKEOVER). This unprecedented level of genetic narrowing threatens long-term breed diversity while delivering questionable commercial benefits, as data shows minimal production advantages despite significant GTPI differences between dominant and diverse bloodlines. Historical precedents like the Bell era demonstrate the potential dangers of such concentration, while economic analysis suggests the premium prices for these genetics may not translate to proportional returns in commercial settings. The article challenges breeders to resist blindly chasing GTPI numbers and instead make conscious decisions to balance genetic progress with essential genetic diversity before irreversible consolidation occurs.

Key Takeaways

  • Just 5 bulls account for nearly 50% of top 100 genomic females, with KARL (17%) and ALTAMAKEOVER (16%) dominating the rankings
  • Despite a 35-point GTPI advantage, daughters of dominant sires show minimal production advantages (+1 protein, +0 fat) while having mixed results in health and fertility traits
  • Each 0.1 increase in SCS costs approximately $25 per cow annually, while each point of productive life translates to roughly $22 in economic value – factors often overlooked when selecting solely on GTPI
  • Previous genetic bottlenecks in Holstein history (Bell era, Blackstar/Bellwood/Emory period) resulted in genetic defects and economic losses once excessive concentration was recognized.

The March 2025 genomic elite female rankings reveal what industry insiders have feared. Still, few have dared to say aloud that the Holstein breed is rapidly becoming the private playground of three dominant sire lines. With BERRYRIDGE SSI KARL-ET daughters claiming 17 spots in the top 100 and PEAK ALTAMAKEOVER-ET securing another 16, including four in the elite dozen, we’re witnessing nothing short of a genetic coup. While genomic enthusiasts celebrate another 10-point GTPI increase, the uncomfortable question remains: are we breeding better cows or just higher numbers?

Alarming Genetic Concentration: Just 5 Bulls Control Half of Elite Genetics

The data doesn’t lie. Based on verified March 2025 genomic evaluations, 33% of the top 100 genomic females trace back to just two bulls. Add in several more appearances by BEYOND LETCHWORTH GIANT-ET (5%), OCD HAYK STAGGER-ET (5%), and AURORA HOWLAND-P-ET (5%), and we’re approaching a scenario where five sires control nearly half of the elite genetics. This concentration isn’t just concerning—it’s potentially dangerous for the breed’s future.

Leading the rankings is OCD BREAKAGE LIANA 59951-ET, born in December 2024, with a jaw-dropping GTPI of 3426. Her genetic profile represents the pinnacle of what genomic selection has produced, but her pedigree also represents our increasingly narrow path.

The presence of polled genetics among elite females like OCD Madrid-P LADY 72924-ET (GTPI 3314) and daughters of Aurora Howland-P-ET demonstrates that selection for management-friendly traits can coexist with high genetic merit.

The elite list reveals that newer bloodlines struggle to break through the established genetic hierarchy. While bulls like PEAK PRIMERO-ET, PEN-COL DENOVO GAMLET-ET, and BOMAZ LODI-ET have daughters in the rankings, they represent a small fraction compared to the dominant sires.

KARL vs. ALTAMAKEOVER: Two Bulls Reshaping the Entire Holstein Breed

The genomic data reveals an unprecedented concentration of genetic influence. Never before has the Holstein breed seen such dominance from so few bloodlines at the highest genetic levels.

When a single sire claims nearly one-fifth of the elite genomic positions, we’re not seeing genetic progress—we’re seeing genetic consolidation. The Holstein is becoming the breed with a thousand bulls but only four grandsires.

Is this a path to long-term genetic improvement, or are we creating a genetic bottleneck that future generations will regret? For perspective, just 37 different bulls sired the remaining 44% of elite females—with none having more than three daughters each in the rankings.

This data reveals a critical insight: the 35-point GTPI advantage of KARL daughters comes with minimal gains in actual production traits (+1 protein, +0 fat) compared to other bloodlines. Yet they offer benefits in terms of udder conformation and productive life. Meanwhile, ALTAMAKEOVER’s daughters excel in production but lag in longevity traits. This begs the question: are we making meaningful progress in overall cow performance or simply reshuffling trait emphasis?

Lessons from History: Have We Forgotten the Bell Era Already?

The Holstein industry has previously faced genetic bottlenecks. In the 1990s, concerns about BLAD and CVM defects highlighted the risks of concentrated genetics. Today’s concentration doesn’t center on a single bull like the infamous Carlin-M Ivanhoe Bell era but rather on a handful of closely related sire lines.

What lessons have we forgotten from previous genetic bottlenecks? In the 1980s, the Bell sons dominated AI lineups, but their genetic defects later emerged and caused significant economic losses. In the 1990s, the Blackstar/Bellwood/Emory cohort created another concentration point. The industry eventually recognized the risk each time, and corrective action followed, but only after the genetic narrowing.

Have we learned nothing from this cyclical pattern? Or are we willfully ignoring history in the pursuit of higher numbers?

The Bottom Line

The dominance of BERRYRIDGE SSI KARL-ET and PEAK ALTAMAKEOVER-ET in the rankings isn’t just a statistical curiosity—it’s a warning sign about the breed’s direction. As these genetics spread throughout the national herd, we risk creating a monoculture vulnerable to yet-unknown challenges.

The choice facing dairy producers is clear: continue following the crowd toward increasingly concentrated genetics or make conscious decisions to maintain genetic diversity while pursuing improvement. Will you be part of the solution or part of the problem?

SexTech Dominates March Genomic Rankings

Sunday, March 16th, 2025

SexTech dominates elite bull rankings, controlling 6 of the top 10 GTPI sires.

Executive Summary

The March 2025 genomic evaluations reveal SexTech’s unprecedented dominance, controlling 31% of bulls over 3250 GTPI and 7 of the top 10 positions, including the two highest-ranking sires at 3411 and 3408 GTPI. This concentration of genetic control coincides with premium pricing for elite bulls whose genetic merit is based solely on predictions rather than proven performance, with most top bulls born just 2-3 months ago.

Key Takeaways

  • Market Concentration Alert: SexTech now controls 31% of bulls over 3250 GTPI and 7 of the top 10 positions, raising concerns about long-term market competition and pricing dynamics.
  • Genetic Turnover Trap: Seven of the top 10 bulls were born in January 2025, just 2-3 months ago, illustrating how today’s elite genetics quickly become tomorrow’s average offerings.

The March genomic evaluations reveal an uncomfortable truth: SexTech now controls six of the top ten positions in the GTPI® rankings, including the two highest bulls in the breed, 3411 and 3408 GTPI. As semen prices for these genetic unicorns continue to rise, dairy producers must ask whether they’re investing in genuine improvement or funding the next round of an increasingly concentrated genetic monopoly.

The New Genetic Aristocracy: A Power Shift in Holstein Breeding

The March 2025 genomic rankings reveal a clear hierarchy in the Holstein genetics business. SexTech’s commanding presence at the top of the rankings isn’t just impressive – it’s potentially concerning for industry competition. Their leading bull (HO840003289278542) at 3411 GTPI and his stablemate (HO840003289278547) at 3408 GTPI give the company a stranglehold on the very pinnacle of Holstein genetics.

Select Sires maintains relevance with SSI-SIEMERS 51801 at 3401 GTPI, securing the third position, while INSEME has placed one bull in the top 10. The distribution of bulls with GTPI values exceeding 3250 shows a significant concentration among a few companies:

AI CompanyBulls Over 3250 GTPIPercentageBulls in Top 10
SexTech5231%7
Select Sires3722%2
PEAK3018%0
INSEME2917%1
Other1811%0
Total166100%10

This concentration of genetic control should alarm producers concerned about long-term market competition. When one company commands nearly a third of elite genetics, what happens to pricing structures and producer choices in the coming years?

For Holsteins, there’s good news! An increase in Predicted Transmitting Ability (PTA) for Milk, Fat, and Protein results in a slight upward trend, adding about +10 to +15 NM$, depending on the bull group (genomic or proven). 

Jerseys, however, have experienced a notable decline. Their PTAs for Milk, Fat, and Protein have dropped significantly (around -100, -6, and -6 pounds, respectively). This decrease translates into a reduction in NM$, averaging between -70 and -50 NM$. 

 Brown Swiss, Guernsey, and Ayrshire bulls, on the other hand, have remained relatively stable, with only minor fluctuations around zero. 

The introduction of 305-AA (Average Age) stands out as the most significant change in the August 2024 evaluations. This new standardization for yield records has moved from the 305-ME mature equivalent to a 36-month average age. Age, parity, and season adjustment factors have been updated. Season adjustments are now based on five U.S. climate regions rather than the previous three, providing a more accurate reflection of environmental differences. Importantly, these new factors are breed-specific, meaning each breed has experienced different impacts from this change.
