Your Top Heifers All Trace to Three Cow Families. That’s a $ 93,300-A-Year Trap.

Monday, March 2nd, 2026

Your top genomic heifers probably trace to three cow families. In a $3,110 heifer market, that concentration can be a $93,300‑a‑year mistake.

Executive Summary: Replacement heifers averaged $3,110 per head in late 2025, inventories are sitting at a 47‑year low, and that makes your heifer pipeline one of the biggest financial risks on your farm. This article shows how herds like Glenn Kline’s — with every heifer genomic‑tested and beef‑on‑dairy dialed in — can still end up with most of their “best” heifers tracing back to just two or three cow families that don’t consistently last three or more lactations. When those same maternal lines also dominate your AI sires, you’re quietly concentrating inbreeding and fragility, not diversifying. On a 400‑cow herd, that concentration can mean 20–30 extra replacements every year, tying up about $93,300 in replacement capital at current prices. You get a concrete 30/90/365‑day playbook: add a cow‑family column to your data, run survival and culling by family, re‑aim sexed/IVF/beef rules at proven‑durable lines, and double-check your sire list by maternal line. The bottom line: genomics and beef‑on‑dairy still drive progress and cash flow — but adding cow family as a sorting column turns your breeding program into a risk‑management tool instead of a $93,300‑a‑year gamble.

USDA’s October 2025 Agricultural Prices report pegged the average U.S. replacement dairy heifer at $3,110 per head— the highest figure ever recorded in that series. By January 2026, the national average eased to $2,860, but top springing heifers in California and Minnesota were still clearing above $4,000. U.S. replacement inventories? A 47‑year low, with CoBank estimating the country is short roughly 800,000 dairy heifers across 2025–2026.

At his Holstein herd in Pennsylvania, Glenn Kline has built exactly the kind of genomic program those prices reward: every heifer is genomic‑tested, lower performers are bred to beef, and IVF is used to multiply the top cows. “Back in 2011, we started on genomic testing, and boy, that’s made a huge difference in our herd,” he told the CDCB industry meeting at World Dairy Expo 2025. When he expanded and had to buy animals in, the gap was obvious. “There was really a significant difference with our original animals lasting longer,” Kline said.

The genomics worked. The bought‑in cows didn’t hold up. But here’s the question Kline’s spreadsheet doesn’t answer — and that most progressive breeders aren’t asking either: which cow families do his best genomic heifers actually belong to? And what does it cost when a handful of famous families quietly dominate your replacement pipeline in the tightest heifer market in five decades?

The Cull Math That Changes Everything

Penn State Extension’s cull‑rate benchmarking using USDA/NAHMS data shows how many cows never reach the point where they’ve truly paid their way. In U.S. dairy herds tracked by NAHMS, the annual combined cull and death rate is around 37–38%, with about 73% of culls involuntary — driven by infertility (23.3%), mastitis (18.6%), lameness, and other biological failures rather than planned marketing decisions.

Penn State and other economic analyses put the full heifer‑rearing cost from birth to calving in the $1,800–$2,400range, depending on system, with roughly $2,000 per head as a solid 24‑month benchmark for many U.S. herds. At that cost level, most operations need three or more lactations before a cow starts delivering a longevity dividend instead of just paying back her childhood.

But NAHMS data still shows average productive life below that three‑lactation mark in many herds, with a large share of cows leaving before they finish a third lactation. Every cow that reaches a fourth lactation saves you at least one replacement you didn’t have to rear or buy and delivers another year of mature‑cow production.

The replacement side of the equation flipped fast. CoBank’s Corey Geiger tracked national averages moving from around $1,140 per head in April 2019 to $2,660 by January 2025, then surging to $3,010 in July 2025 — a 164% jump from that 2019 low. That’s the backdrop for every breeding decision you make right now.

How Genomics Quietly Narrowed the Sire Base

Here’s what the genomic revolution delivered alongside all that genetic gain: a smaller sire base and more concentrated maternal lines. Within the last decade, active Holstein bulls in AI programs dropped from about 2,734 to 1,079, and only 75–100 top genomic young bulls now enter AI each year in the U.S. — down from 1,000+ pedigree‑selected bulls annually before genomics. Big contraction on the male side. And because many of those “new” top bulls come from the same elite cow families, the female side narrows too.

Metric	Pre-Genomic Era	Current Era (2020s)
Active AI bulls (total pool)	2,734	1,079
Young bulls entering annually	1,000+	88 (avg 75–100)

When your genomic‑tested heifer pen is dominated by daughters from three famous cow families, and your AI lineup is stacked with sons and grandsons of those same families, you’re doubling up maternal lines from both sides of the pedigree. The Expected Future Inbreeding (EFI) number on a bull proof might still look acceptable, but EFI is calculated against a base population that’s itself more inbred than it was a decade ago. You’re measuring water depth in a boat that’s already taking on water.

Doekes et al. (2020) analyzed Dutch Holstein Friesians and found roughly 36–99 kg less 305‑day milk per +1% increase in genome‑wide homozygosity, along with longer calving intervals and higher somatic cell scores. That’s the kind of quiet drag you feel when fresh‑pen performance doesn’t match the proofs. Misztal and Lourenco’s 2024 Journal of Animal Science review warned that genomic tools accelerate unfavorable changes in fitness traits alongside production gains, and that management alone can’t fully counteract them if inbreeding continues to rise.

Cow family tracking doesn’t fix inbreeding on its own. It lets you see where you’re stacking weight onto the same thin branches before your fresh‑cow pen and replacement budget start screaming.

What Does a $1,200 Beef‑on‑Dairy Calf Really Cost Your Replacement Program?

On paper, the beef‑on‑dairy logic is clean. You genomic‑test your heifers, rank them by index, breed the bottom slice to beef — capturing a $900–$1,400 beef‑cross calf premium in many 2024–2025 U.S. markets — and point sexed semen or IVF at the top slice to make replacements. The beef check shows up in 90 days. The genomic ranking tells you you’ve kept the “best” heifers.

Then you put the cow family on top. The picture shifts.

In a composite analysis built from several 300–500‑cow Holstein herds, one “plain” family that rarely produced chart‑topping genomic heifers quietly averaged 3.7–4.0 lactations in the parlor. Two fashionable high‑index families averaged 2.4–2.6 lactations, with disproportionate reproductive and transition‑disease culls. Those are herd‑record numbers, not theory. Your exact figures will differ, but the pattern probably feels familiar: some families stay; some don’t.

Genomics lets you see PL, DPR, and health indexes. But if your filter is still mostly “top overall index,” the families that rise fastest aren’t always the ones that handle your transition, lameness, and reproductive pressure best.

Metric	Family A (Durable)	Family B (Fragile)	Family C (Fragile)
Average lactations completed	3.9	2.4	2.6
Share of genomic-tested heifers	22%	31%	27%
Average GTPI rank (percentile)	68th	82nd	79th
Involuntary cull rate	28%	42%	39%
Top culling reasons	Mastitis, injury	Repro, transition	Lameness, repro

Running the Numbers: The Trade

Take a 400‑cow Holstein herd:

Herd size: 400 milking cows
Turnover target: 35% → about 140 replacements per year
Replacement purchase cost (national average): $3,010–$3,110 per head in mid‑ to late‑2025
Durable families: ~3.8 lactations average (turnover ~26% per year)
Fragile families: ~2.5 lactations average (turnover ~40% per year)

In a balanced scenario, overall turnover sits close to 35%. Replacement needs stay near 140 head. Now imagine your replacement pipeline is heavily tilted — 60–70% of your genomic‑tested replacements come from fragile families, rather than a more even mix. Based on the composite herd data, those herds saw replacement needs rise by 20–30 extra heifers per year.

At $3,110 per purchased replacement:

30 × $3,110 = $93,300 per year in additional capital

as long as that concentration-turnover gap persists.

Metric	Durable Families	Fragile Families
Average lactations completed	3.8	2.5
Annual turnover rate	~26%	~40%
Replacements needed (400-cow herd)	104 per year	160 per year
Extra replacements vs. baseline	—	+30 per year
Annual replacement cost at $3,110/head	$323,440	$497,600
Additional capital tied up	—	+$93,300/year

You didn’t make that choice explicitly. You made it when you set beef‑on‑dairy and IVF rules strictly by genomic rank, without asking which families actually survive in your barns.

The 400‑Cow Herd That Added the Cow Family Column

Here’s how those composite herds actually changed their breeding rules — built from several progressive Holstein operations that tracked maternal lines and shared data with their advisors.

Step 1 — Tag every female by maternal line. They added a “CowFamily” field in herd software. Every female was assigned to a family tied back to a base cow, defined strictly by maternal lineage — not marketing labels.

Step 2 — Build one combined heifer file. For every genomic‑tested heifer: ID, sire, birthdate, CowFamily, GTPI or NM$, PL/DPR/health indexes, and dam’s lactation number and culling status. For the first time, genomic scores, cow families, and real survival data lived in the same table.

Step 3 — Run family‑level stats. Average lactations completed, lifetime milk and components, primary culling reasons by family. The pattern was striking: some high‑index families had excellent longevity — gold. Others underperformed their genomic potential, with many second‑lactation exits. Several mid‑index families quietly averaged nearly 4 lactations, with fewer involuntary culls.

The lesson wasn’t “don’t trust genomics.” It was “don’t let genomics outrun what your cow families are telling you about your own barns.”

Step 4 — Rewrite three breeding rules.

Sexed semen allocation. Top heifers within each proven‑durable family got priority, even if their GTPI was mid‑pack.
IVF and donor lists. IVF on high‑index heifers from fragile families was capped; donor status went first to heifers from families that could reach third lactation under current management.
Beef‑on‑dairy targets. Beef semen was pointed at over‑represented, short‑lived families after enough replacements were secured from the durable families.

Within about two years, those herds consistently reported: no single family supplied more than ~30% of replacements, the annual increase in genomic inbreeding slowed, and a higher share of cows reached third and fourth lactation.

These aren’t randomized trials. But they’re real herd‑record results that line up with the math.

Your Sire Analyst’s Quiet Role in This

Your sire analyst isn’t out to sabotage your herd. They’re working with the same tools and incentives: genomic rankings, strong proofs, and semen that sells. When an AI program finds cow families that reliably produce top‑ranking sons, it’s logical to double down. Those families become donors and bull dams for everyone else. Over time, more bulls in your semen tank share the same grand‑dams and great‑grand‑dams, even if the sires change.

NAAB and industry reports show a concentrated semen market, with a small number of large organizations controlling most of the U.S. AI business. That’s efficient for pushing genetic gain. It also amplifies maternal‑line concentration in the client herds unless you actively steer away.

For breeders like Kline, the practical question isn’t whether AI companies are “wrong.” It’s whether their female programs are quietly overriding their own herd’s economics. If your bull list is heavy with sons of cow families that already account for a big chunk of your heifer pen, you’re not diversifying. You’re doubling down.

The Playbook: What to Do Before Your Next Breeding Cycle

In the Next 30 Days

Add the cow family column. Export your female inventory, add a “CowFamily” field, and tie each animal back to a base cow.
Run a concentration check. Pull your genomic‑tested heifer list, sort by GTPI or NM$, and look at the top 25–30%. If three or fewer families supply 60% or more of that group, you’re carrying the concentration risk this article describes.
Cross‑check your main sires. Note the cow families in their maternal pedigrees. If those match your over‑represented families, flag them as “use thoughtfully” instead of default choices.

In the Next 90 Days

Calculate family‑level survival from your own data. Average lactations completed, average lifetime milk, voluntary vs involuntary cull ratio, and top culling reasons — by cow family.
Identify your “insurance” families. Families averaging 3.5+ lactations with lower involuntary cull rates are your built‑in pipeline stabilizers.
Rewrite three core rules: Sexed semen priority goes to daughters from durable families. IVF donor lists start with high‑health, high‑PL heifers from durable families before fragile ones. Beef semen is allocated first to over‑represented, short‑lived families once replacement needs from durable families are met.

In the Next 365 Days

Audit your sire lineup by maternal line. For each bull you use heavily, record the cow family of his dam and grand‑dam. Don’t let half your semen volume come from bulls out of the same two or three families.
Set a practical inbreeding guardrail. Work with your genetic advisor to flag matings in which both the sire and dam come from your most common cow families.
Track outcomes, not intentions. As the first heifers under new rules freshen, watch average lactations completed by family, voluntary vs involuntary culling by family, and total replacements needed per year vs your target.

What This Means for Your Operation

Your genomic ranking list is a tool, not a verdict. It doesn’t know which cow families actually survive under your feed, facilities, and disease pressure. Your cull and longevity records do.
Replacement cost has changed the tolerance for fragility. Going from $1,140 per head in 2019 to $3,010–$3,110 in 2025 means being wrong about cow family durability isn’t a nuisance — it’s a five‑ or six‑figure swing in capital exposure.
Inbreeding penalties are already in your tank and your parlor. The depression numbers from Dutch Holsteins — up to 99 kg less milk per +1% genomic inbreeding — aren’t abstract; they describe what happens when you stack too many related lines.
Beef‑on‑dairy decisions need a family filter. Before you write next season’s beef semen rules, pull the last 50 heifers you bred to beef and tag them by cow family and dam’s lactation. If your best longevity families are taking the hit, your protocol is backwards.
IVF amplifies whatever you point it at. If you aim your IVF budget at cow families that don’t last in your system, you’re multiplying fragility in the tightest replacement window in decades.

Key Takeaways

If three or fewer cow families supply 60%+ of your top genomic heifers, you’re carrying the concentration risk this article lays out. Put a hard cap on your breeding protocols and deliberately feed replacements from underrepresented, proven‑durable families.
If your annual replacement rate has drifted above the mid‑35% range without obvious disease crashes, check whether short‑lived families are quietly driving that turnover. Run replacements‑needed per year by cow family and compare that to your longevity and cull data.
Before your next beef‑on‑dairy semen order, block out an hour to run one report: last 50 heifers bred to beef, tagged by cow family and dam’s lactation number. If durable families are over‑represented in the beef column, fix the rules before the next breeding season.
On your next call with your sire analyst, ask one extra question: “Which bulls in your lineup come from cow families we don’t already have stacked in this herd?” Make maternal‑line diversity part of the conversation, not an afterthought.

The Bottom Line

Open your genomic heifer list right now. Add a cow family column. Sort by family instead of GTPI. How many maternal lines are you actually betting your next three years of replacements on — and do the families carrying the most weight have the track record in your barns to justify it? If you’re already doing what Kline did — leaning into genomics early, pushing for better cows — this isn’t about blaming you. It’s about upgrading the tools so your cow families, not just your proofs, protect the herd you’ve worked hard to build.

Super Bowl LX and the $869-Per-Cow Sire Gap: The Breeding Strategy Your Dairy Can’t Ignore

Sunday, February 8th, 2026

Super Bowl LX will burn $8M a spot. Your sire picks can swing $869 per cow. Still letting someone else call the breeding plays?

Executive Summary: Top‑quartile genetics are already worth $869 more lifetime profit per cow, according to a nine‑year Zoetis study on 12,952 Holsteins across 11 US dairies. This article shows how that gap has widened with the 2025 NM$ revision, where a higher weight on Feed Saved and longevity – and a 11% hit on cow size – quietly killed the idea that a show‑ring cow is also the most profitable commercial cow. Framed against Super Bowl LX’s $8 million ad slots, it argues your sire choices deserve the same level of strategy, because they move far more money across a 200‑cow herd than any 30‑second commercial. You’ll get a concrete “game plan”: a four‑slot sire roster with named December 2025 bulls, a one‑page scorecard to run every bull through, and a simple starting plan for genomic testing on your next 20 heifers. Stories from Simon Vander Woude in California, the Baileys at Moorhouse Hall Farm in the UK, and DataGene focus farms in Australia show what happens when producers stop delegating sire selection and let the numbers challenge old habits. The core message is direct: over the next five years, genetics is shifting from “nice‑to‑optimize” to a structural survival factor for any dairy paid on components.

A nine-year Zoetis study tracking 12,952 Holsteins across 11 US dairies found that cows in the top 25% of genetic profitability generated $869 more in lifetime profit than cows in the bottom 25% (Zoetis, August 2022, ranked by Dairy Wellness Profit Index). On a 200-cow herd, that gap adds up to $173,800 per cow generation. On a 100-cow herd, $86,900. That’s not a model. It’s observed data from real operations over nearly a decade.

Tonight, brands paying $8 million for 30 seconds of Super Bowl LX airtime at Levi’s Stadium have stress-tested their campaigns for months — audience-segmented, ROI-modeled, every frame data-validated. Meanwhile, a 2010 reader survey found that 46% of producers simply use whatever mating program their A.I. company provides, and only 11% match sire traits to individual cow weaknesses. That survey is 16 years old now — and given the complexity genomics has added, the delegation rate may well be higher today.

Your sire selection deserves the same analytical rigor that advertisers bring to a 30-second spot.

The Widening Genetic Gap

Genomic selection has fundamentally accelerated genetic progress in US Holsteins. Before genomics took hold, from 2005 through 2009, the average Net Merit gain for marketed Holstein bulls was roughly $40 per year. Since 2011, that rate has more than doubled. Wiggans and Carrillo documented the acceleration in a 2022 review published in Frontiers in Genetics. CDCB’s own genomic impact data tells a similar story — $40.33 per year from 2005–2010, jumping to $79.20 per year from 2016–2020. The distance between elite and middle-of-the-pack genetics grows larger with each proof round, and if you’re not actively capturing that progress, you fall further behind every cycle.

The December 2025 US Holstein genetic evaluations made the concentration at the top impossible to ignore. Genosource now holds 22 of the top 30 NM$ positions — 73% of the industry’s elite profitability bracket. The number-one bull, GENOSOURCE RETROSPECT-ET, sits at +1,296 NM$. The NM$ true transmitting ability standard deviation is $228 (VanRaden et al., NM$, January 2025), which means a single standard deviation of difference between your sire battery and the industry average shows up as real dollars at the bulk tank. Every month. For years.

Mid-size operations — 100 to 500 cows — feel this most acutely. You’re large enough that genetic differences compound into serious money, but you probably don’t have a dedicated genetics manager parsing proof sheets three times a year.

What Producers Discovered When They Stopped Delegating

Alta Genetics has built its entire product philosophy around what they call the 4-EVENT COW — a cow whose card reads FRESH, BRED, PREGNANT, DRY, and nothing else. No treatments, no repros, no vet calls between those four entries. Their Alta CONCEPT PLUS sire fertility evaluation, built on real pregnancy check data from progressive dairies across North America since 2001, identifies bulls that create more pregnancies faster — CONCEPT PLUS DxD sires deliver a 2–5% conception rate advantage over the average conventional sire on cows, and CONCEPT PLUS 511 sires add 3–7% when using sexed semen on heifers (Alta Genetics, 2025). A mating program adjusts the consistency of type traits within your herd. Sire selection determines the genetic level of the herd itself. Delegate the selection, and no mating optimization closes the gap.

The Zoetis study made this concrete. The difference between top-quartile and bottom-quartile genetics wasn’t just dollars — it was 35% more milk, 44% fewer antibiotic treatments over their lifetimes, 5% less feed for maintenance, and an estimated 10% less enteric methane. And that gap held regardless of management quality across all 11 herds studied. That’s why the conversation has shifted from “genetics is about production” to “genetics is about total cost structure.”

Simon Vander Woude’s operation illustrates how the shift actually happens on a working farm. Vander Woude owns and operates three dairies totaling 6,000 cows near Merced, California, and has run over 10,000 genomic tests with Zoetis CLARIFIDE Plus. His team started genomic testing simply to identify bottom-end heifers to sell off and get heifer inventory in line with cow numbers. But the test results revealed something uncomfortable: they’d been chasing Daughter Pregnancy Rate as a standalone trait without evaluating how it connected to the rest of the animal. “We focused on DPR pretty heavily and kind of forgot about milk for a while,” Vander Woude shared in 2022. “We’ve stubbed our toes plenty along this path.” That honest reassessment reshaped their entire program. Today, they run IVF on top genomic females — 40 to 60 embryo calves born per month — sexed Holstein semen on the next tier, and Angus on everything else. A tiered system that didn’t exist before they let the data challenge their assumptions.

The Bailey family at Moorhouse Hall Farm in Cumbria, England, had a different trigger entirely. John, Kate, and their son Chris — a full-time vet — started genomic testing their heifers after hearing Nuffield Scholar Neil Easter describe how he’d built a herd with youngstock in the top 1% for Profitable Lifetime Index. As they tested, AHDB’s broader UK analysis revealed a startling finding: around 17% of calves had their recorded sires updated when genotypes were analysed — 7% because the wrong sire was recorded, another 10% because no sire was recorded at all (AHDB, 2024). The Baileys now genomic test every heifer, breed their top-performing animals to dairy sires and the bottom 10–20% to beef, and sit just shy of the top 1% nationally for £PLI in their youngstock. “We used to always find an excuse for why a certain cow should be bred,” John Bailey told AHDB. “But now with genomics, the data gives us much more confidence in identifying the bottom performers.”

The 2025 NM$ Revision: Why USDA Rewrote the Formula

Here’s where a lot of conventional wisdom about cow size and type starts to break down.

When USDA researchers ran genomic regressions on actual feed intake data from over 8,500 lactations of more than 6,600 dairy cows in US and Canadian research herds, the number that came back caught everyone off guard: real maintenance costs were 5.5 pounds of dry matter intake 1,000 per pound of body weight per lactation. That’s roughly twice the previously used phenotypic regression estimates. Every producer who’d been selecting for bigger, taller cows had been unknowingly selecting for higher maintenance costs than anyone calculated.

So USDA rebuilt the formula. Here’s what changed (VanRaden et al., NM$, January 2025):

Feed Saved now commands 17.8% combined emphasis — 11% from body weight composite and 6.8% from residual feed intake. Productive Life carries 13% emphasis at $30 per month, and when you add Cow Livability’s 5.9%, the durability complex totals 18.9% — making longevity the largest non-yield trait group in the index. The lifetime economic values driving NM$ are $5.01 per pound of fat PTA and $3.32 per pound of protein PTA, calculated across 2.70 average lifetime lactation equivalents for Holsteins.

And the traditional type-trait weightings? They dropped hard enough to change the conversation:

Trait Category	NM$ Emphasis	Direction	What Changed	Why It Matters for Your Herd
Feed Saved	+17.8%	↑	Real maintenance costs were 2× previous estimates; emphasis jumped from ~9% to 17.8%	Bigger cows now cost you more than the old formula calculated—select for efficiency, not size
Productive Life + Cow Livability	+18.9%	↑	PL at 13% ($30/month), Livability 5.9%—longevity is now the largest non-yield trait group	Cows that last five lactations beat cows that peak high and break down by lactation three
Udder Composite	1.3%	↓	Dropped from ~5%; two decades of selection finished the job	Further emphasis yields diminishing returns on work already done—udders are largely fixed
Feet & Legs Composite	0.4%	↓	Classifier scores correlated poorly with actual lameness and hoof health	Direct health traits predict lameness better than visual scores ever did
Body Weight Composite	−11.0%	↓↓	Active penalty—NM$ now selects against excess cow size	Every extra pound of body weight costs you 5.5 lbs DMI per lactation; the show-ring cow is now a commercial liability

The math is hard to argue with: NM$ has driven a permanent wedge between the show ring cow and the commercially profitable cow. For two decades, the industry could pretend the gap wasn’t that wide. With Udder Composite at 1.3%, Feet and Legs at 0.4%, and body weight penalized at −11%, that pretense is over. You can still breed show cattle. You can still win banners. But the economics now say, clearly and quantifiably, that the traits rewarded in the ring and the traits rewarded at the bulk tank have parted ways.

The type-to-health connection runs deeper than index weightings. Dechow et al. (2003, Journal of Dairy Science) documented a −0.73 genetic correlation between Body Condition Score and Dairy Form in first-lactation Holsteins — meaning cows that score high for angular dairy character are genetically predisposed to thin body condition at calving. That predisposition elevates ketosis risk.

The traits that actually drive longevity are functional: rear udder height, teat placement, and udder depth. Not the visual sharpness that wins ribbons.

One caveat worth stating plainly: if you market breeding stock, embryos, or show cattle, you may rationally weight type traits higher than a commercial herd optimizing for tank revenue. The NM$ recalibration reflects commercial profitability priorities. Seedstock economics are different — that’s a legitimate strategic choice, not a mistake. But don’t confuse the two. And don’t let anyone tell you that a cow that scores EX-95 is automatically more profitable than a VG-86 daughter who freshens easy, breeds back fast, and milks hard for five lactations. The numbers no longer support that story.

Your Game Plan: Three Strategies Producers Are Using Right Now

Build a Complementary Sire Roster — Not a Ranked List

Think of it like building a Super Bowl roster. You don’t field a team of four quarterbacks. You need depth at every position, and each player fills a specific role. Same with your sire lineup.

The instinct is to line up your top four NM$ bulls and start breeding. But a ranked list isn’t a roster. Four bulls who share the same weaknesses leave your herd exposed in exactly the same spots.

A complementary depth chart assigns each sire a defined role:

Roster Position	% of Matings	Strategic Role	December 2025 Example	Key Selection Criteria
Franchise	≈35%	High NM$, balanced, no catastrophic weakness	STGEN STUART-ET (NM$ not specified, 1,666 Milk, 145 Fat, 71 Protein)	Overall profitability, proven reliability, well-rounded trait profile
Component Specialist	≈25%	Maximize fat + protein revenue	GENOSOURCE BENCHMARK-ET (228 CFP, highest among top NM$ sires)	Elite Combined Fat + Protein, strong production firepower
Longevity/Fertility Fixer	≈25%	Address durability and reproduction gaps	FB 8084 ADEBAYO-P-ET (PL +5.3, LIV +4.5, FI +2.5, SCS 2.78, BWC −0.39, polled)	High Productive Life, fertility traits, moderate body weight, functional focus
Outcross/Inbreeding Hedge	≈15%	Distinct sire line and maternal grandsire	Prioritize different sire lines and MGS not in your other three slots	Pedigree diversity, Expected Future Inbreeding <7%, distinct lineage

Adebayo-P is a functional specialist, not a production leader (56M, 54F, 33P per Holstein Association August 2025 TPI list)—that’s precisely why he fills a role your franchise and component bulls can’t. All rankings may shift at the April 2026 proof run.

Verrier et al. (1993, Journal of Dairy Science) showed that factorial mating designs — where dams see several different sires — produced significantly lower inbreeding rates relative to genetic gain than single-sire approaches. And the December 2025 rankings saw considerable reshuffling, including BEYOND SHPSTR GOLLEY-ET vaulting to #2 GTPI at 3,605. A diversified roster absorbs that kind of volatility. A single-sire strategy doesn’t.

Where this can fall short: It takes more time and familiarity with trait profiles than picking one bull. If reading sire summaries feels overwhelming, you can capture roughly 80% of the benefit by setting an NM$ floor and using three bulls from different sire lines — even without position-specific assignments. For more on building genetic selection resources, start with the evaluation archives.

Genomic young sires carry reliability of roughly 70–75%, compared to 95%+ for daughter-proven bulls. Using three or four sires instead of one hedges that reliability gap — another reason the roster approach outperforms going all-in.

Your Halftime Adjustments: The One-Page Sire Scorecard

Every team makes adjustments at the half based on what the first two quarters showed them. Your sire scorecard works the same way — it forces you to look at what your herd actually needs before your next breeding play.

Before you open a catalog or take a call from your rep, answer these questions and write down actual numbers:

What are your current fat and protein pounds per cow? Pull your last three DHIA milk recording reports.
What are your top three cull reasons over the past 12 months? Most DHI software generates this in minutes.
What’s your NM$ floor? With December 2025 bulls clearing $1,200+, there’s little reason to go below $900 on any roster sire.
What’s your maximum Expected Future Inbreeding? Most geneticists suggest keeping genomic inbreeding below 7–8%.
What functional traits does your facility specifically demand? Robotic milking needs teat placement and milking speed. Grazing operations weight feet-and-legs and body weight differently than freestalls.

Tape that sheet to the wall. Next time anyone recommends a bull — your rep, a catalog, a neighbor — run him through the scorecard first.

This doesn’t replace your A.I. rep. It redirects the relationship. You direct the strategy. They source bulls that fit your framework. That’s a fundamentally different conversation than “send me what you think is good.”

One index note: If your plant pays a cheese yield premium, consider weighting CM$ alongside NM$. Under CM$, protein carries $4.73/lb emphasis versus $3.32 in NM$ (VanRaden et al., NM$, 2025). If you’re on a Class I fluid contract, FM$ may be your better primary index. Know your market before you choose your yardstick.

Genomic Test Your Next 20 Replacement Heifers

You don’t have to test every animal tomorrow. Start with the next group approaching breeding age. UK data from the AHDB showed that herds genotyping 75–100% of their heifers had an average Profitable Lifetime Index of £430 per animal in their 2023 calf crop, compared to £237 for herds testing 0–25% of heifers. That £193 gap translates to roughly £19,300 in theoretical profit potential for a typical 175-head herd — but AHDB’s analysis of actual farm business accounts revealed the real advantage at that genetic difference to be over £50,000. Those aren’t projections. They’re margins from real accounts.

Genomic Testing Rate	Avg £PLI Per Animal	Theoretical Profit Potential (175-head herd)	Actual Profit Advantage (Farm Accounts)
0–25% Testing	£237	Baseline	Baseline
75–100% Testing	£430	+£19,300	+£50,000+
The Gap	+£193 per animal	—	Real margins from UK farm business accounts, not projections

Dave Erf, dairy technical services geneticist with Zoetis, offers three ground rules for getting started: have a plan for how you’ll use the results before you test, lay out a herd roadmap of where you’re strong and where you need to improve, and test all your heifers — not just the ones you think are best. “If you just test your best ones, you can’t make a culling decision, because you don’t know,” Erf shared.

The trade-off is real, though. Testing creates a two-tier system — dairy sires on your top genomic females, beef sires on the bottom. If you test but don’t actually follow through on that split, you’ve spent the money without capturing the value. And on very small herds under 50 cows with limited replacement needs, the per-head cost may not generate enough selection differential to justify universal testing. Start with 20 and scale from there.

The Five-Year Outlook: Marginal Edge or Structural Separation

Five years out, is disciplined sire selection a nice-to-have or a survival factor?

The evidence points toward structural separation. CoBank’s lead dairy economist Corey Geiger laid out the financial logic in a March 2025 Knowledge Exchange report: “there’s a clear financial incentive for producers given that multiple component pricing programs place nearly 90% of the milk check value on butterfat and protein.” And the genetic pipeline is delivering. Butterfat in US Holsteins hit a record 4.23% in 2024, and protein reached 3.29% — both per USDA/NASS data. Between 2011 and 2024, butterfat production surged 30.2% and protein by 23.6%, both outpacing the 15.9% growth in fluid milk volume (CoBank, March 2025). For a broader context on where this is heading, see the 2025 genetic evaluation updates.

“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,” Geiger wrote. “Genetics should continue to gain momentum in the coming years.”

In the UK, 112,507 cows were genomically tested in 2024 — a 19% jump over the prior year. The adoption curve is accelerating. Marco Winters, head of animal genetics at AHDB, put it bluntly: “Improving genetics is probably the cheapest and most sustainable way of making long-term improvements to any herd, and when you’re using a genetic index which has been developed specifically to increase profitability, this feeds straight through to a farm’s bottom line.”

In Australia, DataGene’s ImProving Herds project — which tracked 27 Genetic Focus Farms and 7 Herd Test Focus Farms — found that every single case study farm adopting data-informed genetic decisions reported improved business performance, even during a severe milk price crash and drought (DataGene, 2023 final report). Six of seven Herd Test Focus Farms continued testing permanently. Once the feedback loop started working, going back felt reckless.

Here’s what makes genetics different from every other efficiency tool on your dairy. Feed systems, robotic milkers, and activity monitors — they all require ongoing capital and operating expense. Genetic gains are baked into the biology. They compound without additional spend. In a margin squeeze, the operation running genetically superior cows carries a fundamentally lower breakeven. Not because they manage better. Because their cows are biologically cheaper to run.

What This Means for Your Operation

Before your next semen order, build the one-page scorecard. Thirty minutes, five questions, taped to the wall. Every sire candidate is scored against your herd’s actual needs—not catalog rankings or rep recommendations.
This month, genomic test your next 20 breeding-age heifers. Use the results to split your replacement pipeline: dairy sires on top-tier females, beef sires on the rest. Test them all — not just the ones you think are best.
At your next rep conversation, hand them the scorecard and ask them to fill four roster positions—not just recommend their current favorites. Which bull addresses your top cull reason? What’s the Expected Future Inbreeding for each sire mated to your herd? Do they have outcross options from distinct sire lines?
Every proof round (April, August, December), revisit your roster. December 2025 reshuffled the rankings significantly. A lineup built in January may need adjusting by August.
If your herd averages over 1,600 lbs body weight, the NM$ maintenance cost recalibration means your feed costs per unit of production are likely higher than your old genetic plan accounted for. With BWC now carrying −11% emphasis in NM$, selecting for lower body weight composite and positive Feed Saved isn’t optional anymore.
If you market breeding stock or show cattle, recognize that NM$ reflects commercial priorities. Weighting type traits more heavily is a legitimate strategic choice — just make it with full awareness of the trade-off in commercial efficiency.

Questions to Ask Your Genetics Rep This Week

Print this. Bring it up in your next conversation about your semen order.

Can you show me trait profiles — not just index rankings — for every bull in my current lineup?
Which of my current sires directly addresses my top cull reason?
What is the Expected Future Inbreeding for each bull when mated to my herd?
Do you have outcross options from distinct sire lines and maternal grandsires?
How does my current lineup score on Feed Saved and body weight composite under the 2025 NM$ revision?

The Longest Game You Play

Tonight’s Super Bowl ends in four quarters. Your sire decisions don’t resolve for a decade.

Vander Woude has been at this for over a decade now. He wouldn’t still be testing 6,000 cows if he didn’t believe it paid for itself. “It’s really hard to quantify how it pays for itself,” he shared. “But I have a much better herd of cows.” Dave Erf, his Zoetis geneticist, was more specific: “I’ve never seen such a good reproduction performing herd… I think genetics helped them get there.”

Know your cows. Know your numbers. Match the bull to the need. That’s the whole shift in one sentence—and the data shows most of the industry still isn’t doing it.

Your semen tank is right there. The scorecard takes half an hour. And every daughter that walks into your parlor two years from now will be the commercial that plays on repeat, for better or worse, for the rest of the decade.

Key Takeaways

Your sire choices now move $869 per cow in lifetime profit, based on a nine‑year Zoetis study of 12,952 Holsteins on 11 US dairies — that’s $173,800 a generation on 200 cows.
The 2025 NM$ changes pay you more for Feed Saved and longevity and hit you for excess cow size (−11% BWC), so chasing big, showy cows is now a direct hit to commercial profitability.
You can upgrade from “favorite bulls” to a real breeding game plan by running a four‑slot sire roster: franchise profit bull, high‑component hammer, durability/fertility fixer, and an outcross to keep inbreeding in check.
A one‑page scorecard (NM$ floor, EFI cap, top three cull reasons, facility needs) plus genomic testing on your next 20 heifers is enough to start sorting dairy vs. beef matings with confidence.
If you’re getting paid on butterfat and protein, genetics is no longer a “nice extra” — it’s one of the few levers that can permanently pull your breakeven down while feed and labor keep marching up.

Does Your Breeding Program Fit Your Milk Market?

Sunday, December 21st, 2025

The same genetics cost one farm $190,000/year and make another farm $57,000. The difference? Market alignment.

<a href="https://rss.com/podcasts/the-bullvine/2403977/">E447 Does Your Breeding Program Fit Your Milk Mark | RSS.com</a>

Here’s something I’ve been thinking about quite a bit lately. After spending time reviewing proof sheets and talking with dairy farmers from Wisconsin to California, I keep coming back to the same observation: there’s a growing gap between what the catalogs celebrate and what actually drives profitability on individual farms.

Don’t get me wrong—the numbers look impressive. Genetic progress is accelerating. Index values keep climbing. But sit down with producers who’ve been making these decisions for two or three decades, and they’ll share something the marketing materials tend to leave out: genetics that work beautifully on one operation can quietly underperform on another.

What’s interesting here isn’t that some bulls are better than others. It’s that every elite sire represents a specific vision of where dairy is headed—and whether that vision aligns with your milk market, your management approach, and your economic reality is really the question worth exploring.

The Three Gears That Must Mesh

Think of profitable breeding decisions as three interlocking gears: Genetics, Market, and Management. When these gears mesh smoothly, genetic investments translate into income over feed cost and long-term herd health. When they don’t—when you’re selecting for traits your market doesn’t reward or your management can’t support—you’re essentially paying for genetic potential you can’t capture.

As many of us have seen, that’s how you end up with cows that look great on paper but don’t quite pay their way in your specific system.

The visual is simple enough to sketch on a napkin: three gears touching. Genetics turns Market turns Management. If one gear is spinning in the wrong direction—or sized wrong for the others—you get grinding instead of progress.

Gear Misalignment Example

Midwest Freestall — Class III Cheese Plant Contract — Volume-Focused Genetics

Picture a 600-cow Midwest freestall operation shipping exclusively to a cheese plant on a Class III contract. The processor pays heavily on components—protein especially, since that’s what drives cheese yield. At current prices, protein is worth $3.01 per pound and butterfat $1.71 per pound.

The breeding program, though, has been chasing milk volume for years. High-production sires. Big milk numbers. The tank is full, but the tests are running 3.6% fat and 2.95% protein—below the current Holstein breed average of 4.15% fat and 3.36% protein, according to the Canadian Dairy Information Centre’s 2024 data.

Where money leaks out:

Lost protein premium: At 2.95% protein instead of 3.2–3.3%, this herd leaves roughly $0.75–$0.90 per cwt on the table compared to a component-focused herd at similar production levels. On 60 lbs/cow/day, that’s $140–$195 per cow per lactation in foregone protein revenue alone.

Butterfat gap: The 0.3–0.4% fat test difference adds another $95–$125 per cow per year in missed premiums.

Feed efficiency drag: High-volume, low-component cows often require more DMI per pound of milk solids produced. Using USDA’s NM$ 2025 values, moving that extra water through the system costs feed dollars without generating proportional component revenue.

Estimated annual cost for this 600-cow herd: Approximately $150,000–$190,000 in component revenue the cheese plant would have paid—if the genetics matched the market.

The cows aren’t “bad.” The bulk tank isn’t empty. But the breeding program was optimized for a fluid milk check that no longer exists. The Genetics gear is turning toward volume. The Market gear is turning toward components. They’re grinding against each other instead of working together.

Understanding What You’re Actually Buying

Looking at three sires that represent distinctly different breeding philosophies helps make this concrete.

Denovo 2776 Leeds from ABS is built on a premise that resonates with many operations right now: labor is expensive and increasingly difficult to find, so invest in genetics that reduce calving interventions. His pedigree runs through Sandy-Valley Laker back to the De-Su Frazzled 6984 cow family—the same family that gave us Gateway, Hercules, Ajax, and Skeet, according to ABS pedigree records. With essentially flat components, Leeds isn’t designed to transform your butterfat levels. His value proposition centers on strong calving-ease and a solid productive life from a family known for commercial functionality.

Denovo 6856 Hotshot takes a completely different approach. His pedigree traces through Pine-Tree Shadow to the Bomaz Perfect-P line—part of what ABS describes as “one of the premier cow families of the breed for longevity.” Hotshot isn’t positioned as a production leader. He’s built around health, livability, and keeping cows productive through the transition period and beyond.

Urzokari from Synetics represents yet another direction—explicit optimization for robotic milking systems. Emphasizing teat position, udder balance, and locomotion traits that influence whether cows visit the robot voluntarily or need fetching.

Producers are discovering that none of these bulls represents a universally optimal choice. Each makes excellent sense for some operations and may quietly cost money on others. The question isn’t which bull is “best,” but which breeding philosophy fits your particular three gears.

Where NM$ and TPI Fit—And Where They Don’t

Before we go further, it’s worth talking about how this framework relates to Net Merit and TPI, since that’s how most of us were taught to think about genetics.

The April 2025 NM$ revision—documented in detail by Paul VanRaden and colleagues at USDA’s Animal Genomics and Improvement Laboratory—now places 31.8% emphasis on butterfat, 13% on protein, and a combined 17.8% on Feed Saved, which includes body weight composite and residual feed intake. The remaining emphasis spreads across productive life, health, fertility, calving, and conformation traits.

Here’s what’s important to understand: NM$ is designed to maximize lifetime profit for an average U.S. Holstein herd selling into average market conditions. It’s a remarkably well-constructed tool for that purpose. Canadian producers working with LPI or Pro$ face similar considerations—different weightings, different assumptions, same fundamental question of whether those assumptions match your operation.

How the Major Indexes Compare

The differences between selection indexes reflect different market realities and breeding priorities:

NM$ (U.S.) places heavy emphasis on components—31.8% on butterfat alone in the 2025 revision—reflecting the cheese-heavy U.S. processing sector. Feed efficiency gets significant weight at 17.8% combined.
TPI (U.S.) weights production, type, and health traits differently, placing greater emphasis on conformation. Operations selling breeding stock or show cattle often weight TPI more heavily.
Pro$ (Canada) incorporates Canadian market conditions and pricing structures. The formula accounts for Canadian component pricing ratios, which—as we’ll see—are shifting significantly.
LPI (Canada) takes a different approach to balancing production, durability, and health traits within the Canadian context.

The point isn’t that one index is “right,” and others are wrong. It’s that each embeds assumptions about markets, management, and priorities that may or may not match your operation.

A Global Trend, Not Just a North American One

This isn’t just a North American consideration. Globally, component emphasis is intensifying—and the herds that have been selecting for it are pulling ahead.

In Ireland, milk fat content reached 4.51% and protein hit 3.58% in January 2025, according to the Central Statistics Office—both up from the prior year. New Zealand’s Fonterra bases its milk price calculations on standardized 4.2% fat and 3.4% protein, as documented in the Commerce Commission’s September 2025 review—benchmarks that reflect decades of component-focused breeding in pasture-based systems. And across the EU, butter prices hit record highs in early 2025, reaching €7,422 per metric ton in January according to CLAL data—a 36.5% increase over the same month in 2024. Industry analysts describe the fat premium as becoming “structural, not some temporary blip.”

The takeaway? Market alignment isn’t a U.S. phenomenon. It’s a global reality that’s reshaping which genetics deliver returns, regardless of where you farm.

When “Average” Doesn’t Describe Your Situation

But “average” may not describe your situation. If you’re shipping Class III milk to a cheese plant with strong component premiums, NM$ may actually underweight the traits driving your revenue. If you’re in a fluid market with minimal component pay, the 31.8% butterfat emphasis in NM$ could be steering you toward genetics that don’t match your milk check.

The framework in this article doesn’t replace NM$ or TPI—it complements them by asking: Does this index’s assumptions match my actual market, management, and constraints?

Think of NM$ as an excellent starting filter. But the final selection—especially for your top sires getting heavy use—benefits from the three-gear alignment check.

The Concentration Question Worth Understanding

Looking at this trend at the breed level, something jumps out that doesn’t get nearly enough airtime.

Multiple studies have estimated the effective population size of Holsteins—a measure of genetic diversity based on how animals are actually related—at 66-79 animals, despite millions of Holstein cows walking into parlors around the world. Geneticists generally view an effective population size below 50 as the line where long-term adaptability becomes a serious concern, so we’re not over that cliff—but we’re closer than many would guess.

Dr. Chad Dechow, Associate Professor of Dairy Cattle Genetics at Penn State University, has been writing and speaking about this for years. His work shows that genomic selection—for all its tremendous benefits in accelerating genetic improvement—has also sped up how quickly we concentrate genetics in fewer lines.

Why does this matter for your next semen order?

Because the bulls marketed as “outcrosses” today often trace back to the same handful of influential sires, once you unfold the pedigree far enough. And the economic bite of that concentration isn’t theoretical—it’s been quantified.

The Mogul Example: When Success Creates Its Own Risk

Mountfield SSI Dcy Mogul—the youngest Holstein sire to exceed one million units sold. His daughters delivered. His influence now appears throughout the breed’s pedigree, making genuine outcrosses increasingly difficult to find.

Mountfield SSI Dcy Mogul is one of the most influential Holstein sires in breed history. Select Sires announced in September 2017 that he’d exceeded 1 million units sold at just seven years of age, making him the youngest bull to reach that milestone. His impact as a foundation sire for subsequent generations has been enormous.

That success wasn’t accidental. Mogul daughters delivered. But the sheer scale of his use means his genetics now appear in a substantial percentage of the breed’s pedigrees—often multiple times per animal when you trace back six or seven generations.

The concern isn’t that Mogul was a poor bull. He wasn’t. The concern is that when any sire achieves that level of market penetration, finding genuinely unrelated genetics becomes progressively harder. Research by Doublet and colleagues, published in 2019, documented annual inbreeding rates rising to 0.55% per year in the genomic era—roughly double the rate considered sustainable in the long term.

For individual herds, this means that selecting a “new” high-ranking bull may actually be deepening your connection to Mogul, O-Man, Planet, or Supersire rather than diversifying away from them. Checking kinship data isn’t paranoia—it’s due diligence.

What Inbreeding Actually Costs

Italian research from Ablondi and colleagues, published in the Journal of Animal Science in 2023, found that a 1% increase in genomic inbreeding—specifically measured via runs of homozygosity (FROH), which captures actual stretches of identical DNA—is associated with about 134 pounds (61 kg) less milk over a 305-day lactation, along with lower fat and protein yields.

German work from Mugambe and colleagues in the Journal of Dairy Science in 2024 found similar patterns:

32–41 kg less milk per 1% increase
1.4–1.7 kg less fat
1.1–1.3 kg less protein
Calving intervals stretched by roughly a quarter-day per 1% increase

I recently talked with a Wisconsin producer milking about 400 cows who’s been tracking inbreeding and performance for a decade. His take was pretty straightforward: “The daughters are producing more milk than their dams, so the genetic progress is real. But conception rates and feet-and-leg issues have gotten harder to manage. I’m not sure the net gain is as large as the proof sheets suggest.”

The Component Premium Question

The shift toward component-focused genetics has really picked up speed in recent years, especially with the 2025 NM$ revision, which placed 31.8% emphasis on butterfat alone. On paper, that makes a lot of sense given recent price trends. In practice, it depends heavily on where your milk check comes from.

The November 2025 USDA Agricultural Marketing Service announcement showed protein at $3.0143 per pound and butterfat at $1.7061 per pound—a very different picture from a year earlier, when butterfat was over $3.00 a pound. Class III settled at $17.18 per hundredweight. Those relationships move, sometimes dramatically.

Processor Contracts Are Tightening

And processor expectations are tightening—that’s something worth paying attention to. Western Canadian provinces—British Columbia, Alberta, Saskatchewan, and Manitoba—announced through the BC Milk Marketing Board a major component pricing ratio shift effective April 1, 2026, moving from 85% butterfat / 10% protein / 5% other solids to 70% butterfat / 25% protein / 5% other solids. That’s a significant rebalancing toward protein that will reward herds already selecting for it and penalize those who aren’t.

In the U.S., the story is similar. New processing capacity often comes with stricter contract requirements. Today’s direct contracts increasingly expect consistent volume, protein tests above 3.2%, and premium somatic cell counts. If your genetics have been drifting away from protein while you’ve been chasing other traits, the next contract renewal window may deliver an unwelcome surprise.

Quick Math Check: What’s Your Component Revenue Share?

Pull your last six milk checks. Add up the component premiums (fat + protein payments above base). Divide by total milk revenue.

Above 25%: Component genetics is likely paying well for you. The 2025 NM$ emphasis on butterfat aligns with your market.
15–25%: Mixed picture. Component genetics help, but don’t over-rotate away from production.
Below 15%: You may be over-investing in component genetics. Consider whether volume-focused or balanced sires deliver better returns in your specific market.

This 5-minute exercise can save thousands in misaligned genetic decisions.

Red Flag Checklist: 5 Warning Signs Your Genetics Don’t Match Your Market

Your fat or protein test has dropped 0.2%+ over 3 years while selecting high-NM$ bulls. NM$ emphasizes components, so if your tests are declining despite following index rankings, something in your selection isn’t translating to your tank.
Your component revenue share (from the Quick Math Check) is under 20%, but you’re heavily using component-focused sires. You may be paying for genetic potential your market doesn’t reward.
You can’t find a prospective sire with less than 8% relationship to your herd. Genetic concentration has narrowed your options more than you realize—time to seek outcross genetics actively.
Your processor has mentioned tightening component thresholds or premium structures in recent communications. With Western Canadian provinces shifting to 70/25/5 (fat/protein/other) pricing in April 2026 and U.S. processors increasingly requiring 3.2%+ protein for premium contracts, genetic decisions made today need to anticipate tomorrow’s standards.
You’re using beef genetics on more than 40% of your herd but haven’t genomic-tested to identify your true top-tier replacements. With dairy heifer inventories at 20-year lows—2.5 million head as of January 2025, according to HighGround Dairy—the cows you keep replacements from matter more than ever.

If you checked two or more: Your three gears may be grinding. Consider a formal review of your breeding program’s alignment with your current market before your next semen order.

The Feed Efficiency Factor

There’s another dimension to this calculation that’s getting more attention in 2025: feed efficiency. The April 2025 NM$ revision now includes 17.8% combined emphasis on Feed Saved, which incorporates both body weight composite and residual feed intake—a significant increase from previous versions.

Here’s what the research tells us: residual feed intake has moderate heritability, typically estimated between 0.15-0.25 in Holstein populations, making it a meaningful selection target over time. And USDA research used in the NM$ calculations shows that feed costs average about 58% of milk income, broken down into 39% for production costs and 19% for maintenance. That’s not “a big part” of the budget; it’s often the biggest lever you have.

Detailed Per-Cow, Per-Lactation Example

Let’s put real numbers to a side-by-side comparison using November 2025 Class III prices and the economic values from the 2025 NM$ revision.

Scenario: Two cows in the same 500-cow Midwest Class III herd

Factor	Cow A (Volume-Focused)	Cow B (Component-Aligned)
Daily milk	62 lbs	56 lbs
Fat test	3.7%	4.2%
Protein test	3.0%	3.3%
305-day milk	18,910 lbs	17,080 lbs
305-day fat	700 lbs	717 lbs
305-day protein	567 lbs	564 lbs

Revenue calculation (Class III component pricing):

Cow A: Fat (700 × $1.71) + Protein (567 × $3.01) + Other solids ≈ $2,904
Cow B: Fat (717 × $1.71) + Protein (564 × $3.01) + Other solids ≈ $2,927

Component advantage for Cow B: ~$23/lactation

Feed cost calculation (using USDA’s NM$ 2025 values of $0.13/lb DMI and requirements of 0.10 lbs DMI per pound of milk, 8.0 lbs per pound of fat, and 6.5 lbs per pound of protein):

Cow A DMI: (18,910 × 0.10) + (700 × 8.0) + (567 × 6.5) = 11,185 lbs
Cow B DMI: (17,080 × 0.10) + (717 × 8.0) + (564 × 6.5) = 10,810 lbs

Feed cost difference: 375 lbs × $0.13 = $49/lactation advantage for Cow B

If Cow B also has 3% better residual feed intake (genetic feed efficiency): Additional savings: ~325 lbs DMI × $0.13 = $42/lactation

Total advantage for component-aligned Cow B in Class III market: $23 (components) + $49 (baseline feed) + $42 (RFI) = ~$114/lactation

Over a 500-cow herd: That’s roughly $57,000/year in additional margin from aligned genetics—not from buying “better” bulls, but from buying bulls that fit the operation’s market and management.

In a fluid market with minimal component premiums, this math reverses. Cow A’s extra 1,830 lbs of milk volume generates more revenue, and the feed efficiency advantage shrinks because you’re not capturing the component value. The same genetics, completely different financial outcome.

What Specialization Actually Costs

Every specialized sire carries trade-offs embedded in his genetic package. The proof sheet highlights the specialization; it doesn’t spell out what you’re giving up.

Leeds’ calving-ease strength comes from specific physical characteristics—smaller, finer skeletal structure, lower birth weight calves, and reduced pelvic dimensions. For operations genuinely struggling with calving difficulty—assisted births over 18–20%—the trade-off often pencils out. For herds where calving assistance is already well-managed, the structural compromise might cost more than the calving-ease saves.

Hotshot’s emphasis on longevity reveals a different dynamic. His moderate milk proof looks more like a genetic ceiling than a starting point. When bred heifers bring $4,000 or more at auction, and raising costs run around $1,700–$2,400 per head, keeping cows in the herd for more lactations makes sense on paper. But if those cows are giving 6–8 lbs/day less than alternatives, whether longevity genetics pay off depends on your culling rate, replacement strategy, and feed costs.

A Northeast grazing operation I spent time with last spring leaned into longevity-focused genetics five years earlier and were genuinely happy with the outcome. “The per-cow production dropped some,” the producer told me, “but with lower replacement costs and better cow health, we’re actually keeping more of what we make.”

Sire Type	Intended Benefit	Hidden Trade-Off	Best Fit	Expensive Misfit
Calving-Ease (e.g., Leeds)	Lower assisted births, reduced labor during calving, fewer injury losses	Smaller frame, reduced mature size, often comes with 6-8 lbs/day lower lifetime production	First-calf heifers; herds with assisted calvings >18%; operations with limited labor for calving supervision	Well-managed herds with <10% assisted births; operations where replacement heifers cost $4,000+ and production matters more than calving ease
Longevity-Focused (e.g., Hotshot)	Extended productive life, lower replacement costs, better transition cow health	Moderate milk proofs often represent genetic ceiling, not starting point; slower genetic progress on production traits	High replacement costs ($2,200+ per heifer); grazing operations; herds targeting 3.5+ lactations; limited heifer inventory	Operations with strong cull cow markets; herds breeding beef-on-dairy on bottom 40%; processors paying volume bonuses; low feed costs favoring higher production
Robotic-Optimized (e.g., Urzokari)	Improved voluntary robot visits, better teat positioning, reduced fetch time	Emphasis on udder/teat traits may sacrifice component genetics or production potential; value only captured if robots utilized efficiently	Robotic dairies; operations struggling with fetch rates >15%; herds prioritizing labor efficiency over per-cow production	Conventional parlor operations; herds with no robot plans; component-paying markets where udder traits matter less than tests

When Realignment Pays Off: A Recovery Story

What happens when a producer recognizes the mismatch and corrects course? I talked with a 550-cow operation in central Minnesota that went through exactly that process.

“We’d been chasing TPI for about eight years,” the herd manager explained. “Good bulls, good genomics, no complaints about the genetics themselves. But we were shipping to a cheese plant, and our protein test just kept sliding—went from 3.25% down to 3.05% over that stretch. Meanwhile, the premiums for protein kept going up.”

When they ran the numbers in 2022, they realized they were leaving close to $180 per cow in component revenue on the table annually. “That’s when it clicked. We weren’t using bad genetics. We were using the wrong genetics for our market.”

They shifted their sire selection criteria—still using high-ranking bulls, but filtering hard for positive protein deviation and component balance. Three years later, their protein test is back to 3.22% and climbing.

“The genetic progress feels slower on paper,” he admitted. “But the milk check is bigger. That’s the number that actually matters.”

Regional Considerations

Where you farm changes these calculations more than most proof sheets acknowledge.

In the Southeast and Southwest, producers dealing with persistent heat stress often find that moderate production with stronger health and fertility traits out-earns elite production genetics that struggle through extended summers. In the Upper Midwest and Northeast, grazing-heavy systems face different realities—a cow built for a California dry lot isn’t always the cow you want walking hillsides in Vermont.

The Beef-on-Dairy Connection

The three-gear framework applies to more than just which dairy sires you’re using—it also shapes your beef-on-dairy strategy.

The 2024 NAAB semen sales report shows 7.9 million beef semen units flowing into U.S. dairy operations, representing over 80% of all beef semen sales. Meanwhile, dairy heifer inventories expected to calve dropped to 2.5 million head as of January 2025—the lowest level since USDA began tracking this data, according to HighGround Dairy analysis. CoBank research projects 357,490 fewer dairy heifers for 2025 compared to the prior year, driven largely by beef-on-dairy breeding decisions.

Here’s where the gears mesh—or grind: If you’re using beef genetics on your bottom-tier cows, you’ve already made a three-gear decision. You’re saying those animals don’t fit your Genetics goals (not worth keeping daughters from), don’t justify the Management investment of raising replacements, and the Market for beef calves currently rewards that choice.

But the framework cuts both ways. With heifer supplies this tight, the cows you do keep replacements from matter more than ever. Beef Magazine’s November 2025 report notes that beef-on-dairy cattle now represent 12–15% of all fed slaughter—the crossbreds have become an indispensable part of the beef supply chain. That’s fine, as long as your top-end genetics are truly aligned with your dairy operation’s market and management. Using beef on low-merit cows makes sense; accidentally breeding beef on cows that should be producing your next generation of high-component replacements is a costly mistake that compounds over time.

Finding Genuine Genetic Diversity

While genetic gains have more than doubled in the genomic era, breeding for diversity inside Holsteins now takes real effort.

For Purebred Holstein Operations

Seek out niche Holstein lines. Legacy maternal lines like Hanover-Hill, Landmark, Meteor, Durham, or Elegant, which were prominent 20–30 years ago but don’t dominate today’s rankings, can bring different genetics to the table.

Request genomic kinship data. Most major AI companies can show you how closely a prospective sire is related to your herd’s core cow families. CDCB offers inbreeding tools as well. For operations that haven’t genomic-tested their cows yet, current testing runs around $40–50 per head—a worthwhile investment if you’re serious about managing inbreeding across your herd.

Unfold pedigrees further back. Many so-called outcross sires look different in the first three generations, then converge on Mogul, O-Man, Planet, or Supersire once you get back to generation six or eight.

Consider the National Animal Germplasm Program. USDA’s germplasm program maintains semen and embryos from older, less-represented lines to preserve genetic diversity for long-term breed health.

“I’ve stopped looking at the top 10 TPI list entirely. If a bull doesn’t have positive deviation for protein and decent feet-and-legs, he doesn’t enter my tank, regardless of his rank. The proof sheets tell you what a bull can do genetically. They don’t tell you whether those genetics fit your parlor, your market, or your management. That’s the part you have to figure out yourself.”

— Wisconsin producer, 650-cow operation

A Framework for Matching Genetics to Your Operation

Five Questions Before You Pick a Bull

1. What’s my actual milk market? How much of your check comes from components versus volume?

2. What’s my primary constraint? Is involuntary culling above 25%? Are assisted calvings over 18%? Is production lagging?

3. Does this sire truly address that constraint? If calving isn’t a major issue, calving-ease sires might just be giving away production.

4. How closely is this bull related to my herd? Check genomic kinship or pedigree overlap.

5. What does the five-year math look like? Account for production, components, feed costs, replacements, and health.

The Larger Perspective

When you put all of this together, what’s interesting is how much breeding has shifted from “Which bull is best?” to “Which bull best fits what I’m actually trying to do here?”

The Holsteins that maximize returns on a 3,000-cow California dry lot shipping Class III milk are not the same Holsteins that fit a 200-cow Wisconsin grazing herd shipping mostly fluid milk. Both operations might reasonably use bulls like Leeds or Hotshot—but in very different proportions, for very different reasons, and with very different expectations.

Three Actions Before Your Next Semen Order

Calculate your component revenue percentage from your last six milk checks. If it’s under 15%, reconsider heavy use of component-focused sires.
Request kinship reports on your top 5 prospective sires from your AI representative. Flag any showing an elevated relationship to your existing cow families or heavy Mogul/O-Man/Planet ancestry.
Identify one genuine outcross sire from an underrepresented maternal line for 5–10% of your matings—not to chase diversity for its own sake, but to maintain options as the breed continues to concentrate.

The tools to make smarter, more aligned decisions exist—genomic kinship, feed efficiency data, inbreeding metrics, and diverse sire options. The challenge, and the opportunity, is taking the time to line those tools up with the reality of your own farm.

The Bottom Line

What’s been your experience with specialized genetics? Have calving-ease, longevity-focused, or component-heavy sires delivered the returns their proofs suggested under your conditions? The most useful lessons often come from comparing what the proofs promised with what actually showed up in the bulk tank and the balance sheet.

Key Takeaways

Fit beats rank. The same genetics can cost one farm $190,000/year and add $57,000 to another—the difference is market alignment, not genetic quality.
Misalignment drains profit quietly. Volume genetics in a cheese market can leave $150,000–$190,000 annually on the table, even when production looks strong.
NM$ is designed for the average herd. The 2025 revision puts 31.8% emphasis on butterfat. If your market doesn’t reward components, you’re paying for genetic potential you can’t capture.
Inbreeding costs compound. Each 1% increase means ~134 lbs less milk plus weaker fertility—and at 0.55% annually, the breed is accumulating it faster than ever.
Before your next semen order: Calculate your component revenue share (5 minutes), request kinship data on prospective sires, and reserve 5–10% of matings for genuine outcrosses.

EXECUTIVE SUMMARY:

The same genetics can cost one operation $190,000 a year and add $57,000 to another. The difference isn’t genetic quality—it’s market alignment. This article introduces a three-gear framework (Genetics, Market, Management) that helps producers evaluate whether their breeding program actually fits their milk check. Drawing on USDA’s April 2025 NM$ revision and peer-reviewed research, it demonstrates how misaligned genetics can quietly drain profitability even when production looks strong. Practical tools include a 5-minute component revenue analysis, five questions to ask before selecting any sire, and strategies for finding genuine diversity as the breed concentrates. The goal isn’t finding “better” bulls—it’s finding bulls that fit your operation.

The Next Frontier: What’s Really Coming for Dairy Cattle Breeding (2025-2030)

Thursday, July 24th, 2025

Stop chasing milk volume myths. CRISPR gene editing delivers $5,000 per cow annually while genomic testing cuts feed costs through precision breeding.

<a href="https://rss.com/podcasts/the-bullvine/2135292/">E327 The Next Frontier: What’s Really Coming for D | RSS.com</a>

The dairy industry’s sitting on the edge of something big. We’re talking about technological and genetic breakthroughs between 2025-2030 that’ll completely change how we think about dairy cattle breeding. And here’s the thing—these aren’t just fancy lab experiments. They’re real solutions that can put serious money in your pocket through lower feed bills, reduced labor costs, and premium milk markets.

The secret? Stop thinking of these innovations as complicated science projects and start seeing them as profit opportunities. Because that’s exactly what they are.

Game-Changing Tech: What’s Coming in the Next Few Years (2025-2030)

1. Designer Milk Through Gene Editing and Selection

***Milk Composition Improvements Through Gene Editing***

When it’s happening: 2025-2027.

Remember when organic milk was just a crazy idea? Well, get ready for the next revolution. Scientists are using CRISPR technology—think of it as molecular scissors—to create milk that’s actually better than what nature gave us. They’ve figured out how to eliminate beta-lactoglobulin, the protein that makes some people allergic to milk. Plus, by genetic selection, dairy farmers can now bump up casein content by 17-35%, which means their desired casein milk makes more and better cheese, reduces gastrointestinal symptoms, and potentially benefits for bone health and blood pressure management. While regulatory approval remains a key step, forward-thinking producers are positioning their herds to capitalize the moment these markets open.

What it means for your wallet:

Premium markets willing to pay 15-25% above commodity prices.
Processors offering component bonuses for high casein milk.
New customer segments you couldn’t reach before

The bottom line: We’re talking $3,000-$5,000 extra revenue per cow annually if you can access these specialty markets. That’s not pocket change.

2. Breeding Healthier Animals Through Smart Genetics

When it’s happening: 2025-2028.

Here’s something every dairy farmer knows that sick cows don’t pay bills. The good news? Genomic selection is getting scary good at predicting which animals will stay healthy. We’re seeing genetic markers for lameness resistance and mastitis immunity that actually work.

Digital dermatitis—that foot disease that drives everyone crazy—has heritability rates of 0.21 to 0.25. Translation: you can breed your way out of this health problem.

Real numbers that matter:

Each avoided mastitis case saves you $444.
Preventing lameness stops those brutal 20% milk production drops.
Some farms are seeing 300% better mastitis resistance.

Real farm example: Dave Kammel in Wisconsin tells it straight—his two robots save him three hours of daily labor while his cows stay healthier. The Casey Family Farm in Ireland? They cut labor needs by 25% with robotic systems.

3. AI That Actually Thinks Like a Dairy Cattle Breeder

When it’s happening: 2025-2028.

Forget the sci-fi nonsense. Today’s AI systems can crunch over 200 genetic markers while watching your cows 24/7 through sensors. Robotic milking systems aren’t just milking machines anymore—they’re learning each cow’s preferences and optimizing everything in real-time.

What you get:

70% reduction in milking labor costs (yes, really)
Minimum 15% higher milk yields
Disease detection up to a full week before you would have notice symptoms.

One UK study showed AI catching mastitis early enough to save €1,500 per case. That’s the kind of technology that pays for itself.

The Medium-Term Game Changers (2026-2030)

4. Know Your Calf’s Future at Birth

When it’s happening: 2026-2028.

Here’s where it gets interesting. Genomic testing on newborn calves gives you 65-80% reliability on their lifetime breeding values. Compare that to the 20-25% you get from just looking at the parents, and you’ll understand why this matters.

The Council on Dairy Cattle Breeding tracks 49 different traits and can estimate lifetime profit through their Net Merit Index. A calf with a $300 breeding value will make you $450 more over her lifetime than one with -$150 value.

The math is simple: Stop feeding $1,400-$2,000 worth of feed to animals that’ll never pay it back. Test early, cull smart, and put your money on winners.

5. Finally Fixing Fertility Issues

When it’s happening: 2027-2030.

Fertility’s been the black sheep of dairy genetics for years—low heritability, lacking in reliable data points and very hard to improve. But combining advanced reproductive tech, along with genomic selection, is changing the game.

A 5-day improvement in calving interval saves a 1,000-cow dairy $17,500 annually. Bump those 21-day pregnancy rates from 12% to 33%, and you’re cutting calving intervals by 63 days. Each new pregnancy is worth $100-$500, depending on who you ask.

6. Feed Efficiency That Actually Matters

***US Dairy Farm Operating Cost Structure – Key Areas for Technology Impact***

When it’s happening: 2027-2030.

Feed costs eat up 50-60% of milking herd variable expenses. Even small improvements can help—big time. A modest 5-15% improvement in feed conversion efficiency means $87,500-$393,750 in annual savings for a 1,000-cow operation.

And here’s the kicker: new feed additives like Rumin8’s product are showing 95.2% methane reductions without hurting milk production. Massachusetts dairy farms using anaerobic digesters are offsetting over 2 million pounds of CO2 annually while powering 1,600 homes. Some EU farms are earning €12,000 annually in carbon credit subsidies.

***Economic Impact Timeline: Dairy Breeding Technologies 2025-2030***

From Science to Sales Pitch

STgenetics’ Juan Moreno has this figured out. Instead of talking about complex genomic algorithms, he talks dollars and cents. A $30 genomic test saves $1,400 by helping you avoid raising the wrong heifer. His EcoFeed technology saves 10% on feed costs—and feed represents 55% of your animal operating expenses.

Moreno doesn’t try to sell one-size-fits-all solutions either. He knows a grass-based farm in New Zealand has different priorities than a confinement operation in Wisconsin.

Making “Net Zero” Actually Make Sense

Stop thinking of environmental goals as costs. Start thinking of them as profit centers. Including that feed conversion efficiency improvement cuts a dairy farm’s methane emissions? Along with reducing your biggest expense. Plus, water conservation that looks good to regulators. It’s also cutting your water bill by up to 30%.

The USDA’s throwing $7.7 billion at climate-smart practices. Processors are starting to pay premiums for verified farm sustainability data. Smart farmers are figuring out how to get paid for doing what they should be doing anyway.

Real-World Results You Can Actually Believe

Korean Robotic Success

Korean dairy farms using robotic systems have experienced 2.44-2.88 kg more milk per cow daily, plus 0.10-0.11 more calves per cow annually. Labor savings were huge, especially for smaller family operations.

***International Genetic Progress Rates with Genomic Selection***

Welsh Genomic Testing Win

Welsh farmers genomically testing heifers have found that 23% would’ve been kept using old methods but shouldn’t have been retained. Net benefit: £19.39 per heifer after testing costs. Over a whole herd and multiple generations, that compounds fast.

***Technology ROI Payback Periods for US Dairy Farms***

The Bottom Line

Look, nobody’s saying this transformation will be easy. But the dairy farms that figure out how to use these tools first are going to have massive advantages. Lower costs, higher production, access to premium markets—the whole package.

The key is remembering that this isn’t about being the most high-tech farm in the county. It’s about being the most profitable. These innovations aren’t just technological advancement—they’re direct paths to better margins, smoother operations, and farms that’ll still be thriving when your kids take over.

Early adopters always win in agriculture. The question isn’t whether these changes are coming—they’re already here. The question is whether you’ll lead the charge or spend the next decade playing catch-up – or even, sadly, having to exit the industry.

Smart money says it’s time to start planning your move.

KEY TAKEAWAYS

Challenge the “Volume Over Value” Orthodoxy: While traditional breeding focuses on milk volume, precision genetic engineering for milk composition delivers $3,000-$5,000 additional annual revenue per cow through premium A2 markets and enhanced casein content (17-35% increases), with processing efficiency improvements that benefit component-based pricing structures—proving composition drives profitability more than volume.
Implement AI-Powered Precision to Cut Labor 70%: Robotic milking systems equipped with predictive analytics reduce labor costs by up to 70% while increasing milk yields minimum 15% (22 to 25 liters daily per cow), with mastitis detection capabilities saving €1,500 per case through early intervention—addressing the critical labor shortage while improving herd health and production efficiency.
Leverage Genomic Testing for Strategic Culling Decisions: Early-life genomic testing provides 65-70% breeding value reliability versus 20-25% from parent averages, enabling identification of low-genetic-merit animals before investing $1,400-$2,000 in feed costs—a calf with $300 Net Merit breeding value generates $450 more lifetime profit than one with -$150 value across three lactations.
Optimize Total Farm Feed Efficiency for Maximum Cost Savings: Genetic selection for feed conversion efficiency delivers $87,500-$393,750 annual savings per 1,000-cow operation through modest 5-15% improvements, directly addressing feed costs that represent 50-60% of variable milking herd expenses while positioning farms for carbon credit revenue streams worth up to €12,000 annually through methane reduction initiatives.
Adopt Global Success Models Over Traditional Approaches: New Zealand farms achieve genetic progress equivalent to eight years of conventional breeding through female genomic selection combined with sex-selected semen, while Korean operations report 2.44-2.88 kg daily production increases and 0.10-0.11 more calves per cow annually—proving integrated precision breeding systems deliver measurable commercial results that transform farm economics.

EXECUTIVE SUMMARY

The dairy industry’s obsession with milk volume over composition is costing farms thousands while precision genetic engineering and AI-powered breeding systems generate $87,500-$393,750 annual savings per 1,000-cow operation. Revolutionary CRISPR-Cas9 technology will eliminate milk allergens while through genetic selection increasing casein content by 17-35%, opening premium markets worth 15-25% above commodity prices—translating to $3,000-$5,000 additional revenue per cow annually. Meanwhile, genomic testing at birth provides 65-80% breeding value reliability compared to just 20-25% from traditional parent averages, enabling early culling decisions that save $1,400-$2,000 in feed costs per low-merit heifer. AI-powered robotic milking systems slash labor costs by up to 70% while boosting milk yields 15%, with early mastitis detection saving €1,500 per case through predictive analytics that identify disease up to a full week before symptoms appear. Many countries have demonstrated genetic progress equivalent to eight years of traditional breeding through strategic female genomic selection, feed intake and efficiency improvements that deliver immediate returns by reducing the largest variable cost and that numerous technologies work in commercial environments. It is all possible. Opportunity knocks for business oriented dairy farmers by incorporating precision genetics that transform complex science into measurable farm profits.

The Component Revolution: Why Milk Volume is Dead and Your Genetics Program Needs Surgery

Sunday, June 22nd, 2025

While you’re celebrating 80-pound cows, component-focused farms bank $120K more annually. The “pounds mentality” is dead—here’s your survival guide.

EXECUTIVE SUMMARY: The dairy industry’s obsession with milk volume is financially destroying farms that refuse to adapt to component economics. While traditional operations chase fluid milk production that crawled ahead just 15.9% since 2011, component-savvy farms captured the real money: butterfat production exploded 30.2% and protein surged 23.6%. Processing giants have committed $8 billion in new capacity through 2027, all designed for high-component milk, while Federal Milk Marketing Order reforms now align 90% of milk check value with butterfat and protein content. The April 2025 Holstein genetic evaluations revealed the largest base change in history—a 45-pound rollback on butterfat—proving genetic progress is accelerating away from volume-focused breeders. New Zealand’s component-focused strategy achieved 23-26% unit price increases across major dairy categories despite declining milk volumes, demonstrating that quality commands premium pricing globally. For a 500-cow operation, a mere 0.1% increase in butterfat generates $90,000-$120,000 additional annual revenue, yet most farms continue optimizing for yesterday’s metrics. Challenge conventional wisdom: audit your genetic program against component values within 30 days or watch profitable opportunities slip away to farms that embrace this economic revolution.

KEY TAKEAWAYS

Genetic Revolution Accelerating: The April 2025 Holstein evaluations showed a historic 45-pound butterfat rollback and 30-pound protein rollback, with genomics now driving 70% of production improvements compared to 40% pre-2009—farms using genomic testing achieve £193 higher lifetime profitability per animal
Component Premium Explosion: A 500-cow operation generates $90,000-$120,000 additional annual revenue from just 0.1% butterfat increase, while overall production optimization (68 lbs/day at 3.8% fat vs. 70 lbs/day at 3.5% fat) delivers $12,000-$18,000 extra revenue per 100 cows annually
Processing Infrastructure Bet: $8 billion in new dairy processing capacity through 2027 is strategically designed for manufactured products requiring high-component milk—cheese manufacturers achieve 8.3% yield increases per protein percentage point, creating powerful market pull for component-rich milk
Federal Policy Alignment: June 2025 FMMO reforms updated protein assumptions from 3.1% to 3.3% and other solids from 5.9% to 6.0%, directly rewarding component optimization while traditional volume-focused cooperatives inadvertently penalize farms investing in genetic and nutritional strategies
Global Market Validation: Despite 0.5% decline in fluid milk collections, New Zealand achieved record payouts exceeding $10.00 per kilogram of milk solids through component-focused payment systems, enabling 23-26% unit price increases across major export categories—proving component optimization creates sustainable competitive advantages

component optimization, dairy genetics, milk production profitability, butterfat protein content, genomic testing

What if I told you that while you’ve been celebrating 80-pound cows, the smart money moved to something completely different? Here’s the shocking reality reshaping dairy economics: U.S. butterfat levels just hit 4.36% through March 2025-up from 3.95% in 2020. Meanwhile, milk solids production jumped 1.65% even as total volume dropped 0.35%. This isn’t a gradual change – it’s economic disruption happening right now.

The brutal mathematics: While you’ve been chasing milk pounds, butterfat production exploded 82 million pounds in Q1 2025 alone-a staggering 3.4% increase with virtually no fluid volume increase. Component-savvy farms are banking serious money, while volume-obsessed operations struggle with compressed margins.

The Death of “Pounds Per Day” Thinking

Forget everything you think you know about dairy profitability. The April 2025 Holstein evaluations revealed the largest genetic base change in history-a 45-pound rollback on butterfat and a 30-pound rollback on protein. This massive adjustment proves that genetic progress in components is leaving conventional volume-focused breeders in the dust.

The industry doesn’t want you to know that despite overall production declining 0.35% year-to-date, milk solids production jumped 1.65% through March 2025. Smart farmers optimizing components generate substantial additional revenue while commodity milk faces oversupply pressure.

The USDA’s Agricultural Marketing Service reports clearly show that “Plenty of cream is available throughout the country, and it is generally affordable for butter makers.” This abundance of butterfat-rich cream creates opportunities for processors while challenging traditional volume-focused farms.

The $8 Billion Processing Bet That Changes Everything

Here’s a fact that should change how you think about 2025: The U.S. dairy industry has more than $8 billion in processing infrastructure investment happening right now.

Major Processing Investments Creating Demand:

Company	Investment	Location	Focus
Walmart	$350 million	Texas	Distribution hub
Fairlife	$650 million	New York	Fluid milk expansion
Chobani	$1.2 billion	New York	Yogurt/processing

This isn’t just expansion-it’s demand creation that will compete for your milk. Much of this new capacity focuses on manufactured products that depend entirely on component levels, not fluid volume.

Federal Policy Finally Rewards Component Focus

Critical FMMO changes took effect June 1, 2025, creating direct financial incentives for component optimization. After nearly 18 months of hearings, the USDA announced that the Federal Milk Marketing Order modernization passed in all 11 FMMOs.

Key changes affecting your paycheck:

Updated Composition Factors: Effective December 1, 2025, protein content assumptions increase from 3.1% to 3.3%, other solids from 5.9% to 6.0%, and nonfat solids from 9.0% to 9.3%. This adjustment should increase classified milk prices due to higher assumed component content.

Class I Price Mover Changes: The calculation returned to the “higher-of” advanced Class III or Class IV skim milk prices, creating more stable pricing.

If you’ve been investing in genetics and nutrition to boost components, you will get paid for it. If you haven’t? You’re financing those who have.

Your Financial Future Depends on This Decision

Component Performance Reality Check:

2020 average butterfat: 3.95%
2025 average butterfat: 4.36% (+0.41 percentage points)
2020 average protein: 3.181%
2025 average protein: 3.38% (+0.199 percentage points)

The evidence overwhelms any skepticism: USDA raised its 2025 milk production forecast to 227.3 billion pounds, but the real money lies in component optimization. All-milk prices are forecasted at $21.60 per cwt for 2025, creating margin pressure for volume-focused operations.

Yet component-focused farms are generating substantial additional revenue. With the Net Merit $ (NM$) index increasing butterfat weighting from 28.6 to 31.8, while protein weighting decreased from 19.6 to 13, market signals clearly favor component optimization over volume production.

Why Most Farms Are Getting This Wrong

The psychological barrier runs deeper than economics. Many cooperatives continue paying primarily on volume, treating component premiums as secondary considerations. This volume-focused approach inadvertently disincentivizes investments that would optimize component yields.

Current market conditions amplify these problems. Domestic cheese consumption declined by 56 million pounds during Q1 2025 despite surging butterfat production, creating an oversupply crisis for commodity milk and pressuring Class III prices downward.

Most refuse to acknowledge the controversial reality: Component pricing systems now attribute nearly 90% of milk check value to butterfat and protein, yet traditional management systems continue prioritizing volume metrics.

The Bottom Line

The component revolution isn’t coming-it’s here. U.S. butterfat levels hit record highs, milk solids production jumped 1.65% while volume dropped, and Federal Milk Marketing Orders underwent their biggest reform in decades.

The choice is stark: Adapt your genetics program to prioritize components over volume, or watch profitable opportunities slip away to farms that embrace this new reality. With butterfat levels jumping from 3.95% to 4.36% in just five years and the largest genetic base change in Holstein history, your delay costs real money every month.

Your immediate next step: Schedule a comprehensive review of your genetic program within the next 30 days. Use the April 2025 genetic evaluations with their historic base changes to restructure your breeding strategy around component optimization.

Challenge conventional wisdom: Why are you still celebrating milk volume when 90% of your check value comes from components? When the market clearly rewards component optimization, how can you justify breeding decisions based on outdated volume metrics?

The farms that understand this distinction first will capture the profits that volume-focused operations leave unclaimed.

Your Best Genetics Are Programmed to Fail – Here’s the $3-6 ROI Recovery Plan

Friday, June 20th, 2025

Stop activating cooling at THI 72. New research proves heat damage starts at 68—costing you thousands in hidden feed losses. Time to rethink everything.

EXECUTIVE SUMMARY: Your highest-producing cows are genetically programmed to fail when temperatures rise, and it’s costing the global dairy industry $30 billion annually. Groundbreaking research analyzing 388,629 daily feed intake records from 6,333 Holstein cows reveals that heat stress impacts begin at THI 68—not the industry-standard 72-80 thresholds most producers still use. For each unit increase in THI above critical levels, dry matter intake plummets by 4.13% and energy-corrected milk drops by 3.25%, with multiparous cows suffering disproportionately higher losses than first-lactation animals. The most devastating discovery: negative genetic correlations (-0.06 to -0.48) between high production potential and heat tolerance mean decades of breeding for milk yield has inadvertently engineered thermal vulnerability into every Holstein. Analysis of 56 million production records documented cumulative losses of 1.4 billion pounds of milk worth $245 million between 2012-2016, while precision cooling infrastructure demonstrates 3:1 ROI when activated at research-proven thresholds. Italian dairy research confirms that feed efficiency averages just 1.38 kg FPCM per kg DMI, with half of all milk production dependent on purchased feeds—making thermal resilience critical for maintaining profitability as climate pressures intensify. It’s time to abandon comfort-based cooling assumptions and implement evidence-based thermal management that protects both immediate profits and long-term genetic investments.

KEY TAKEAWAYS

Precision Threshold Activation Delivers 3:1 ROI: Activate cooling systems at THI 68 instead of traditional 72-80 thresholds to prevent 4.13% DMI losses and 3.25% energy-corrected milk reductions, with documented returns of $3-6 for every dollar invested in strategic fan placement and sprinkler cycling protocols.
Your Best Genetics Are Your Biggest Heat Risk: Negative genetic correlations (-0.06 to -0.48) between high milk production and heat tolerance mean multiparous cows—your highest producers—suffer disproportionate thermal damage, requiring targeted cooling strategies for the most valuable segment of your herd.
Feed Efficiency Crisis Hidden in Plain Sight: With feed efficiency averaging only 1.38 kg FPCM per kg DMI and 50% of milk production linked to purchased feeds, heat stress compounds the largest operational expense while compromising the foundation of dairy profitability—making thermal resilience essential for competitive advantage.
Generational Wealth Destruction from Heat-Stressed Dry Cows: Heat stress during pregnancy produces daughters with 4.9 lb/day lower lifetime milk production, creating multi-generational losses that compound across lactations—making dry cow cooling a critical long-term genetic investment, not seasonal comfort.
Global Climate Reality Demands Immediate Action: With 2023 recorded as 1.36°C warmer than pre-industrial levels and climate projections showing 100-300 annual heat stress days by 2050, operations implementing research-based cooling strategies gain sustainable competitive advantages over those clinging to outdated assumptions.

heat stress dairy, precision cooling systems, dairy feed efficiency, milk production losses, farm cooling ROI

What if your highest-producing cows are genetically programmed to fail when temperatures rise? New research in The Journal of Dairy Science, analyzing 388,629 daily feed intake records from 6,333 Holstein cows across Wisconsin, Michigan, and Iowa, has uncovered a troubling reality: the genetic traits that make your Holsteins exceptional milk producers are the same ones making them vulnerable to heat stress. And it’s hitting your operation where it hurts most – feed efficiency and dry matter intake.

This isn’t just an academic distinction. The economic carnage is staggering: for each unit increase in the Temperature-Humidity Index (THI), dry matter intake (DMI) decreases by 4.13%, and energy-corrected milk (ECM) drops by 3.25% in mid-lactation cows. Analysis of 56 million production records from 18,000 US farms between 2012-2016 documented cumulative losses of 1.4 billion pounds of milk, translating to $245 million in lost revenue. But here’s what most producers don’t realize – the feed efficiency losses may be even costlier than the milk losses.

The most insidious discovery from the University of Wisconsin-Madison research is the negative genetic correlation between high production potential and heat tolerance, ranging from -0.06 to -0.48. Translation? The genetic selection that created your high-producing, feed-hungry Holsteins also engineered thermal vulnerability into every animal.

With 2023 recorded as 1.36°C warmer than the pre-industrial era, the question isn’t whether heat stress will impact your operation – it’s whether you’ll abandon outdated assumptions before they bankrupt your farm.

The Hidden Genetic Crisis in Your Herd

Why your best producers are your biggest risk

Here’s the counterintuitive reality reshaping dairy genetics: cows genetically predisposed to higher dry matter intake and lower feed efficiency are inherently more susceptible to heat stress.

The University of Wisconsin research found that heritability estimates for thermotolerance were higher (0.16-0.50) than general heritability estimates (0.16-0.33) for DMI and residual feed intake. This means genetic differences in heat tolerance become more apparent precisely when producers think their cows are still “comfortable.”

Think of it like breeding racehorses for speed without considering endurance – you get impressive performance under ideal conditions, but when the track gets challenging, your best performers struggle the most.

The Lactation Reality Check

Multiparous cows – your highest producers and most valuable animals – show significantly greater susceptibility to heat stress than first-lactation animals. The research demonstrates that thermotolerance genetic variance increases with lactation, meaning your most experienced, highest-producing cows need the most aggressive heat abatement strategies.

When THI rises above critical thresholds, homeothermic animals like dairy cows actively reduce their metabolic rate to minimize endogenous heat production. This includes reduced gut motility and rumination, leading to reduced feed intake due to gut fill. Additionally, excessive heat directly impacts the appetite-regulating center in the hypothalamus, with research indicating damage to hypothalamus neurons and reduced gene expression of neuropeptides associated with appetite regulation.

Global Economic Reality: The $30 Billion Crisis

Regional impacts reveal industry-wide vulnerability

Heat stress isn’t uniform across dairy regions. Consider these documented impacts based on recent research:

United States: The livestock industry faces annual losses of $2.3 billion per year from heat stress, with dairy accounting for over 50% of these costs. Analysis of 56 million production records from 18,000 US farms (2012-2016) documented cumulative losses of 1.4 billion pounds of milk, translating to $245 million in lost revenue.

European Union: In Galicia, Spain, critical THI thresholds for milk yield occur at 72, but lower thresholds of 64 for protein and 63 for fat indicate that milk quality deteriorates before quantity. Above these thresholds, losses reach 0.249 kg of milk, 0.008 kg of protein, and 0.006 kg of fat per day per THI unit increase.

China: Researchers have identified “heat-stressed milk protein decrease syndrome” (HS-MPD), where heat stress significantly decreases milk protein content without corresponding reductions in DMI or overall milk yield, revealing hidden metabolic disruptions that traditional monitoring misses.

India: Heat stress contributed to a reduction of 0.73 million liters of milk in 2020. Research on Thai-Holstein cattle identified THI 76 as the critical threshold, with milk yield declining by 0.218 kg at THI 80 for high Holstein genetics.

Your Evidence-Based Recovery Strategy

Precision solutions that protect profits and genetics

Research demonstrates that strategic implementation based on verified thermal thresholds provides substantial return on investment, with documented returns of $3-6 for every dollar invested in cooling systems. But success depends on precision, not comfort-based guesswork.

Tier 1: Precision Threshold Management (All Operations)

Strategic Activation at THI 68: Based on the University of Wisconsin research, cooling systems must activate at THI 68, not traditional thresholds of 72-80. Calculate THI using the verified formula: THI = (1.8 × T°C + 32) − (0.55 − 0.0055 × rh%) × (1.8 × T°C − 26).

Precision Fan Placement: Industry specifications call for 36-inch fans spaced a maximum of 30 feet apart, 48-inch fans within 40 feet, installed 7.5-8 feet above stalls, angled for continuous airflow delivering minimum 200 FPM at cow level. Critical detail: Fans should run continuously at 65°F, not just when it “feels hot” to humans.

Smart Sprinkler Cycling: In controlled studies, low-pressure coarse droplets (1.8-2.8 liters per minute) in 1.5-minute cycles every 15 minutes have shown documented milk yield improvements. The key is the off-period – allowing skin to dry with fan assistance prevents heat retention.

Tier 2: Nutritional Support and Genetic Integration

Metabolic Support: Heat stress fundamentally alters nutrient metabolism. Recent research on transition dairy cows shows that strategic nutritional interventions during periods of metabolic stress can significantly impact performance outcomes. Strategic feeding times, energy density optimization, and specific additives, including electrolytes, rumen modifiers, antioxidants, and osmolytes, can combat metabolic disruptions.

Feed Efficiency Considerations: Contemporary research demonstrates that while heat stress impacts both DMI and energy-corrected milk production, the relationship between feed efficiency metrics requires careful evaluation. Studies show that DMI reduction occurs through both physiological adaptation (reduced gut motility) and neurological pathways (hypothalamic appetite regulation).

Thermotolerance Selection: With heritability estimates of 0.16-0.50 for heat tolerance traits, genetic selection offers permanent, cumulative gains. The research shows that genetic merit for DMI and RFI is more evident when cows are exposed to heat-stress conditions, suggesting that direct selection can lead to genetic improvement in thermotolerance.

Real-World Implementation: Learning from Research

Evidence from multiple research stations

The University of Wisconsin research provides compelling evidence from real dairy operations. Data collection across six research stations in Wisconsin, Michigan, and Iowa from 2007 to 2024 represents diverse management systems and environmental conditions.

Research Station Insights: The study encompassed operations at the University of Wisconsin-Madison (multiple locations), USDA-ARS Dairy Forage Research Center, Michigan State University, and Iowa State University. This geographic diversity ensures applicability across major dairy regions.

Feed Efficiency Reality: Recent research on dairy cow nutrition demonstrates that feed efficiency responses to environmental stressors involve complex interactions between rumen microbial populations, metabolic pathways, and genetic factors. Studies show that targeted nutritional interventions can help maintain performance during challenging conditions.

Practical Applications: The research methodology used in these studies – including esophageal tubing for rumen fluid collection, real-time monitoring of environmental conditions, and comprehensive metabolic profiling – provides validated protocols that progressive operations can adapt for their own monitoring systems.

Implementation Timeline for Different Farm Scales

For Operations Under 200 Cows

Month 1-2: THI monitoring implementation using the verified calculation formula and basic fan installation
Month 3-4: Low-pressure sprinkler integration with strategic cycling protocols
Month 5-6: Shade structure completion and feeding schedule optimization
Expected outcome: Protection of highest-producing animals during critical thermal stress periods

For Operations Over 500 Cows

Comprehensive precision cooling: Automated systems with THI-based activation at verified thresholds
Advanced monitoring integration: Real-time THI and animal behavior sensors to predict heat stress before clinical signs
Genetic selection integration: Active incorporation of thermotolerance traits into breeding programs
Research-Based Monitoring: Implementation of validated physiological monitoring protocols based on university research methodologies

Current Industry Research Trends

Emerging nutritional strategies

Recent studies in the Journal of Dairy Science demonstrate the potential for targeted nutritional interventions to support cows during environmental stress. Research on direct-fed microbials shows promise for supporting rumen function during challenging conditions, while studies on dietary fat supplementation reveal complex interactions between nutrition and environmental adaptation.

Feed efficiency research developments: Contemporary research continues to refine our understanding of feed efficiency metrics under varying environmental conditions. Studies examining the relationship between DMI, energy-corrected milk production, and environmental factors provide insights for optimizing management strategies.

Genetic selection advances: University research programs are developing more sophisticated tools for genetic selection that incorporate environmental resilience alongside traditional production traits. The heritability estimates documented in the Wisconsin study provide the foundation for these breeding advances.

The Bottom Line: Your Immediate Action Plan

The research is unambiguous: heat stress impacts begin at THI 68, documented through analysis of 388,629 daily feed intake records from 6,333 Holstein cows. This threshold represents the point where your highest-genetic-merit animals begin suffering metabolic damage that compounds across generations.

Your immediate priority is to install THI monitoring at the cow level and activate cooling at 68 THI using the verified calculation formula. The research demonstrates that moderate heritability estimates, especially under thermal-stress conditions, indicate that direct selection can lead to genetic improvement in thermotolerance for DMI and residual feed intake.

Week 1-2: Implement real-time THI monitoring using the research-verified calculation. Install basic shade and optimize water access within 50 feet of feed areas.

Week 3-4: Evaluate current fan placement against industry specifications. Upgrade systems to activate at research-proven thresholds rather than comfort-based assumptions.

Month 2: Integrate strategic sprinkler systems with documented cycling protocols that maximize cooling effectiveness while preventing heat retention.

Month 3: Begin genetic evaluation for thermotolerance in breeding decisions. With heritability estimates of 0.16-0.50 documented in the research, genetic selection provides permanent, cumulative protection against escalating climate challenges.

The competitive reality: Operations implementing precision cooling strategies based on verified research thresholds gain sustainable advantages over those clinging to outdated assumptions. The research clearly demonstrates that both DMI and residual feed intake are traits susceptible to heat stress, making thermal resilience essential for maintaining feed efficiency and profitability.

Your choice is clear: Continue operating under dangerous threshold fallacies while your best genetics suffer documented metabolic damage, or implement evidence-based cooling strategies that protect both immediate profitability and long-term herd resilience.

The research has quantified the problem and provided the solutions. The question is whether you’ll implement them before your competitors do.

The Silent Genetic Squeeze: Is Holstein Breeding Painting Itself into a Corner?

Thursday, May 15th, 2025

Holstein inbreeding has tripled in a decade. Discover how hidden genomic risks threaten dairy profits and what you can do to protect your herd’s future.

<a href="https://rss.com/podcasts/the-bullvine/2029427/">E261 The Silent Genetic Squeeze: Is Holstein Breed | RSS.com</a>

The relentless pursuit of genetic advancement in Holsteins has created an uncomfortable truth the industry refuses to confront: we’re creating a narrow genetic highway with no exit ramps. While milk production has soared through genomic selection, inbreeding has silently tripled in elite lines over just one decade. This genetic narrowing threatens long-term sustainability and demands immediate action from every stakeholder in the dairy industry – including YOU.

Remarkable genetic progress in Holstein cattle has transformed dairy production, but beneath the celebrated gains lurks a concerning trend that many farmers either don’t notice or choose to ignore. The genomic revolution that accelerated genetic improvement has simultaneously accelerated inbreeding at rates unprecedented in breed history.

You’ve probably heard whispers about this at dairy conferences or read passing references in industry publications. Perhaps you’ve noticed subtle changes in the “modern Holstein” – that increasingly angular, refined animal appearing in show rings and high-ranking genomic lists. But few connect these dots to the underlying genetic squeeze right before our eyes. And why would they? The major AI companies aren’t highlighting this problem in their glossy catalogs, are they?

The Inbreeding Paradox: What the Numbers Tell Us

When did you last scrutinize the inbreeding metrics in your genetic evaluations? If you’re like most producers, you monitor Expected Future Inbreeding (EFI) values when selecting service sires. But here’s the uncomfortable truth: EFI isn’t telling you the whole story – and the organizations supplying your genetics know it.

The divergence between genomic inbreeding levels in Holstein bulls (rising to 15.2%) and the declining number of active AI bulls (down 61%) creates a dangerous genetic bottleneck.

The difference between EFI and genomic inbreeding is like comparing your TMR formulation to what the cow’s sort and consume. One gives you the big picture; the other tells you what’s happening where rubber meets road.

EFI measures a bull’s average relationship to the broader population (currently heifers born in 2020), while genomic inbreeding (F_ROH) directly measures actual homozygosity in an individual’s DNA. This distinction matters tremendously when making mating decisions in your breeding program.

What makes this particularly troubling is that the base population used to calculate EFI is becoming more inbred each year. Between 2015 and 2020, the average EFI of the Holstein base population jumped from 7.5% to 9.4%. This means the genetic “yardstick” we use to measure inbreeding is shrinking, creating the illusion of stability when inbreeding is accelerating. It’s like measuring water depth in a sinking boat – the numbers stay the same while you slowly drown.

DEBUNKED: “If a bull’s EFI is low, he’s an outcross.” This common assumption falls apart under scrutiny. A bull can show a low EFI relative to today’s highly inbred base population yet still be closely related to other elite lines. This creates a false sense of security when making breeding decisions, particularly when using multiple “elite” bulls across your herd that secretly share recent common ancestry.

Contract limitations on elite bulls further distort the picture. When high Net Merit$ sires are restricted to specific breeding programs or available only through exclusive contracts, their genetics eventually enter the broader population through sons and maternal grandsons. By then, a new generation of even more inbred sires dominates the market, continuing a cycle of intensifying homozygosity that isn’t fully captured by EFI values.

Follow the Numbers: A Decade of Genetic Narrowing

The data tells a compelling story of rapidly diminishing genetic diversity. In just one decade (2010-2020), genomic inbreeding in Holstein bulls skyrocketed from approximately 5.7% to 15.2% – a staggering 168% increase.

Meanwhile, active AI bulls declined precipitously, from 2,734 in 2010 to just 1,079 in 2020. That’s a 61% reduction in the available gene pool in just 10 years.

Let’s put this in perspective:

Metric	2010	2020	Change
Elite Genomic Sires	5.7%	15.2%	+168%
Active AI bulls	2,734	1,079	-61%
EFI base population	7.5%	9.4%	+25%

You might think, “But genomic selection has dramatically improved our herds. Isn’t this just the price of progress?”

That’s partly true. Genomics allows us to identify elite genetics with unprecedented accuracy and speed. But the unintended consequence is that we’re now selecting from an increasingly narrow pool of animals that share more and more of their ancestry.

Only 75-100 top genomic young bulls enter AI programs annually today, compared to over 1,000 pedigree-selected bulls pre-2010. With three major U.S. cooperatives now controlling over 80% of semen sales, we’re essentially drinking from the same concentrated genetic well – and it’s getting more focused every year. Is anyone asking what happens when that well runs dry?

What’s Driving This Trend?

This genetic bottleneck didn’t happen by accident. Several forces are working together to squeeze our Holstein gene pool:

Genomic selection efficiency

Genomic testing has revolutionized our ability to identify genetic outliers earlier and more accurately. That’s the good news. The flip side? We’re identifying the same families repeatedly because we’re selecting for the same traits using the same algorithms. It’s like using the same filter on your DHIA sheets month after month – you’ll keep identifying the same cows as top performers. As these related animals dominate the rankings, they’re used more intensively, concentrating their genetics in the population.

Restricted access to elite genetics

Have you noticed that the most exciting new bulls often have fine-print limitations? These restrictions aren’t just marketing gimmicks- they fundamentally alter how genes flow through the population. Elite bulls primarily mate with elite cows, creating a separate genetic stream that only gradually filters down to commercial herds, by which time inbreeding has intensified further within the elite nucleus. When did you last have unrestricted access to the industry’s absolute top genomic sires? The answer is likely never.

Industry consolidation

Remember when there were dozens of competitive AI organizations, each with distinct breeding philosophies? Today’s landscape looks vastly different. Stud consolidation means fewer decision-makers directing the genetic future of the breed, often with similar selection objectives driven by identical economic indices like NM$, TPI, and JPI.

The beef-on-dairy effect

The explosive growth of beef-on-dairy breeding, 7.9 million units of beef semen used in dairy herds in 2023, means fewer dairy females contribute to the next generation of purebred Holsteins. This further shrinks the dairy genetic pool, concentrating selection on a smaller nucleus of elite cows bred to elite bulls. It’s like how keeping fewer replacement heifers intensifies selection pressure – except now we’re doing it across the entire breed.

The Real-World Impact on Your Herd

This isn’t just an abstract genetic discussion; inbreeding has tangible effects on your bottom line and day-to-day operation.

The economic impact of inbreeding rises from 10% to 20%, the lifetime profit loss per cow escalates dramatically from $450 to over $3,700, with corresponding declines in production and fertility. *

For every 1% increase in inbreeding:

Lifetime milk production decreases by 177-400 pounds
First-lactation fat and protein yields drop by about 2 pounds each
Productive life shortens by approximately 6 days
Calving interval extends by 0.19-0.34 days
Net Merit declines by about $23-25

These might seem like small numbers individually, but they compound quickly, much like subclinical milk fever impacts that aren’t obvious day-to-day but erode profitability over time. A cow at 15% inbreeding (now increasingly common) could face production losses of 584-730 kg of milk, extended calving intervals of 5-8.5 days, and lifetime profit reductions of $1,035-1,890 compared to a cow at 5% inbreeding.

However, perhaps the most concerning thing for some breeders is the emerging correlation with linear type traits. While research hasn’t definitively linked inbreeding directly to specific conformational changes, there’s growing evidence that our current selection path is creating a “modern type” characterized by:

Decreased strength scores
Shallower body depth
Higher pin placement

These trends align with recent changes to selection indices. The April 2025 update to the CDCB Net Merit formula explicitly increased emphasis on “smaller stature cattle with more focus on dairy form” while penalizing stature at -$0.45/lb.

What if… we’re selecting a dairy cow that excels on paper but lacks the physical robustness to thrive in real-world conditions? What if the next major disease outbreak targets a genetic pathway we’ve inadvertently narrowed through intense selection?

Is this the robust dairy cow we want for the future? Or are we blindly following economic indices without questioning the long-term consequences? The answer depends on your perspective and breeding goals. Still, the narrowing genetic base means we’re increasingly locking ourselves into a particular type with fewer options to course-correct if needed.

Where Are We Headed? Projecting the Future

If current trends continue unabated, with inbreeding increasing at 0.25-0.44% annually, elite Holstein bulls could reach 18-22% average genomic inbreeding by 2030. The effective population size could drop below 50, which geneticists consider the minimum threshold for maintaining long-term adaptability.

What happens after another decade of accelerating genetic concentration? The risks intensify:

Emerging recessive disorders

As homozygosity increases, so does the probability of expressing harmful recessive genes. Through testing, we’ve managed known haplotypes like HH1-6, CVM, and BLAD, but new, currently unidentified recessives will inevitably emerge as inbreeding intensifies. Without genetic diversity to provide alternative alleles, these conditions could become increasingly difficult to manage, like controlling digital dermatitis when every cow in your herd carries the same susceptibility genes.

Reduced genetic resilience

A narrow genetic base means less capacity to adapt to new challenges, whether emerging diseases, climate shifts affecting heat tolerance, or evolving consumer demands requiring different milk components. The traits we might need in the future could be the ones we’re inadvertently selecting against today. Are we removing the very genes that might help dairy cattle survive in an uncertain climate future?

Diminishing returns on genetic progress

Eventually, we hit what geneticists call the “genetic ceiling”-the point where progress slows or stalls because we’ve exhausted the available genetic variation. The very tools that accelerated our progress could ultimately limit our future options.

The economic impact compounds over time:

Inbreeding Level	Milk Yield Loss (kg)	Calving Interval (+days)	Lifetime Profit Loss ($)
10%	259-406	1.9-3.4	230-450
15%	584-730	5.1-8.5	1,035-1,890
20%	1,168-1,460	10.2-17.0	2,300-3,780

Taking Control: Practical Solutions for Your Breeding Program

Despite these concerning trends, you’re not powerless. Here are practical steps you can take to balance genetic progress with maintaining diversity:

ACTION CHECKLIST: 5 STEPS TO MANAGE INBREEDING TODAY

DEMAND genomic inbreeding information (F_ROH) from your genetic provider
IMPLEMENT genomic audits of your replacement heifers
SET a maximum acceptable inbreeding increase per generation (<0.1%)
DESIGNATE 15-20% of matings to true outcross sires
MONITOR linear traits for signs of reduced robustness

Look beyond EFI

When evaluating bulls, don’t just check the EFI value. Demand genomic inbreeding information (F_ROH) from your genetic provider. Some progressive AI companies now include this data, particularly for bulls marketed as “outcross” options. Understanding the homozygosity in your prospective matings gives you a more accurate picture of inbreeding risk.

Implement genomic audits

Consider genomic testing your replacement heifers, not just for selection, but specifically to monitor inbreeding levels. Pay special attention to runs of homozygosity (ROH) greater than 4 Mb, which indicate recent inbreeding that’s particularly concerning. These genomic audits can reveal inbreeding hotspots in your herd that pedigree analysis might miss, like how milk culturing identifies specific pathogens that bulk tank SCC alone doesn’t reveal.

Utilize advanced mating software

Modern mating programs like Select Mating Service (SMS), Optimal Genetic Pathways, and Genetic Audit can optimize for genetic gain and inbreeding control. Set a maximum acceptable inbreeding increase per generation (ideally <0.1%) and let the software help you balance progress with diversity. Tools like MateSel or the CDCB’s Inbreeding Calculator can help identify matings that minimize inbreeding while maximizing genetic gain.

Strategic crossbreeding

Consider structured crossbreeding systems like ProCROSS (Montbeliarde × Viking Red × Holstein) for a portion of your herd. Research consistently shows these systems maintain productivity while improving fertility, reducing calving difficulties, and eliminating inbreeding concerns in the crossbred animals. Dedicating 20% of your matings to well-planned crossbreeding can provide valuable genetic risk management, like diversifying your feed inventory rather than relying on a single forage source.

Seek true outcross genetics

Work with your genetic provider to identify bulls less related to your cow families. Sometimes these aren’t the highest-ranking bulls on popular indices, but they may offer valuable genetic diversity that pays dividends in future generations. Don’t just look at the bull’s inbreeding- examine his relationship to your specific herd’s genetic makeup.

Consider embryos from gene banks

The US National Animal Germplasm Program (NAGP) preserves 98.2% of segregating loci found in Holsteins. Access to this genetic material could provide true outcross options that are increasingly rare in commercial channels. These “genetic time capsules” represent diversity rapidly disappearing from the active population.

The Industry’s Responsibility

Individual farmers can’t solve this challenge alone. The entire dairy genetics industry needs to acknowledge the problem and take collective action:

CDCB reforms

The CDCB should report genomic inbreeding (F_ROH) alongside EFI in evaluations to provide a more complete picture. They could also implement inbreeding caps within selection indices to discourage excessive homozygosity. Making inbreeding more visible in evaluations would bring much-needed transparency to the issue.

Sire diversity quotas

AI studs should maintain genetic diversity by ensuring that 15-20% of their catalogs feature bulls with less than 8% genomic inbreeding and low kinship to the top 100 sires. This provides accessible outcross options to all breeders, not just those with the resources to seek specialty genetics. Why don’t we demand this level of transparency from our genetic suppliers?

Transparent reporting

Breed associations like Holstein Association USA should regularly publish trends in genomic inbreeding, not just in population averages, but specifically in the elite breeding nucleus where future AI sires originate. This data should be publicly available and easily understood, allowing farmers to make informed decisions.

Research incentives

Universities and the USDA-AGIL should prioritize research on optimizing the balance between genetic gain and diversity preservation, including developing selection indices that explicitly value genetic uniqueness. Current economic indices focus almost exclusively on short-term production traits without accounting for the long-term value of genetic diversity.

Education initiatives

Extension services and industry organizations must help farmers understand the full implications of inbreeding and provide practical guidance on managing it effectively. Many producers don’t realize how dramatically inbreeding has increased or how it might affect their operations over the long term.

The Bottom Line

The Holstein breed stands at a genetic crossroads. We’ve made remarkable progress in productivity, but we’re borrowing from the future to pay for today’s genetic gains. The narrowing genetic base, evidenced by skyrocketing inbreeding coefficients and a shrinking bull population, threatens the long-term sustainability and adaptability of the breed we depend on.

As one dairy geneticist bluntly stated, “We’re mining genetic capital faster than replenishing it. The bill will come due in calves born with recessive defects we can’t even name yet.”

You have the power to influence this trajectory, both through individual breeding decisions and by demanding more transparency and commitment to genetic diversity from industry organizations. The Holstein breed has thrived because of its adaptability, ensuring it maintains enough genetic variation to evolve for the next century.

Ask yourself: Are you selecting for the subsequent lactation or breeding for the next generation? Like balancing your ration for immediate milk production versus long-term cow health, your genetic strategy requires thinking beyond immediate results. The answer will determine not just your herd’s future, but the future of the Holstein breed itself.

The time for action is now. Start by examining the true inbreeding levels in your herd. Challenge your genetic provider to supply bulls with verified low genomic inbreeding. Implement mating strategies that actively manage homozygosity. And most importantly, join the conversation about genetic diversity at industry meetings, breed association gatherings, and in discussions with AI representatives.

What will you do differently in your next genetic selection decision? How will you balance your breeding program’s immediate needs with the long-term sustainability of the genetic resources we all share? What’s the ONE change you’ll make to your breeding strategy after reading this?

The time for this conversation isn’t somewhere in the future- it’s now, while we still have genetic diversity to preserve.

Key Takeaways:

Elite Holstein genomic inbreeding tripled (5% → 15%) in 10 years, faster than EFI metrics reveal.
EFI vs. reality gap: Base population adjustments mask elite subgroup risks, enabling “hidden” homozygosity.
Rising inbreeding correlates with -400 lbs milk/1%, +9-day calving intervals, and weaker conformation traits.
$1,890+/cow profit loss at 15% inbreeding; 20% levels could double losses by 2030.
Solutions: Crossbreeding (ProCROSS), gene banks, and industry-wide sire diversity quotas.

Executive Summary:

Modern Holstein breeding faces a silent crisis: genomic inbreeding in elite lines has surged from 5% to 15% in 10 years, driven by AI consolidation and overreliance on top sires. While industry metrics like Expected Future Inbreeding (EFI) downplay risks, true genomic inbreeding correlates with reduced milk yields, fertility issues, and a concerning “modern type” of weaker, shallower cows. With active AI bulls halved since 2010 and studs controlling 80% of genetics, unchecked trends could slash lifetime profits by $3,700/cow by 2030. The article urges immediate action, from crossbreeding to demanding genomic inbreeding (F_ROH) data, to balance genetic progress with diversity before the breed hits a genetic ceiling.

Breeding for the Win: From Kentucky Derby Champions to World Dairy Expo Grand Champions

Saturday, May 3rd, 2025

Kentucky Derby champs hold genetic secrets for breeding World Dairy Expo royalty. Outpace competitors with track-tested breeding strategies.

<a href="https://rss.com/podcasts/the-bullvine/2013001/">E248 Breeding for the Win: From Kentucky Derby Cha | RSS.com</a>

The pursuit of championship excellence isn’t limited to one species. The genetic principles that create Kentucky Derby winners hold powerful lessons for dairy breeders aiming to produce the next World Dairy Expo Grand Champion. Those who master these cross-species strategies will be milking champions while the competition struggles with mediocrity. It’s the difference between filling your barn with cows that command attention or settling for a herd that barely pays the bills.

Secretariat, the legendary 1973 Triple Crown winner, represents the pinnacle of Thoroughbred genetic selection. His record-setting performances at the Kentucky Derby, Preakness, and Belmont Stakes demonstrate how elite <a href='https://www.thebullvine.com/mating-recomendations/16-sires-dairy-breeder-accelerate-genetic-gain-herd/' data-lazy-src= — Secretariat, the legendary 1973 Triple Crown winner, represents the pinnacle of Thoroughbred genetic selection. His record-setting performances at the Kentucky Derby, Preakness, and Belmont Stakes demonstrate how elite genetics translate into championship excellence-the same principles dairy breeders can apply to produce World Dairy Expo champions. At necropsy, Secretariat’s heart was estimated at 22 pounds, roughly three times the size of an average horse’s heart, showcasing how exceptional physiological traits backed by strategic breeding create once-in-a-generation champions.

Breeding Champions: A Tale of Two Species

Let’s be honest – what dairy breeder hasn’t dreamed of leading the Supreme Champion across the colored shavings at the World Dairy Expo? That moment when Judge Brian Carscadden or Pat Conroy raises their hand in your direction represents the pinnacle of breeding achievement, just as the Kentucky Derby winner’s circle does for Thoroughbred breeders. While these animals couldn’t appear more different, the genetic principles behind creating champions share striking similarities.

Pursuing genetic excellence in both arenas represent mankind’s highest achievement in selective breeding. It’s about identifying, selecting, and combining elite genetics with precision and purpose. But here’s the wake-up call: Thoroughbred breeders have been refining their craft since the 1700s and some of their strategies could revolutionize your dairy breeding program faster than a fresh heifer lets down her milk.

What’s fascinating is how these seemingly different worlds – dirt tracks and box stalls – follow parallel paths in the quest for genetic superiority. By examining what makes Kentucky Derby winners and applying these insights to dairy cattle, you gain a competitive advantage that most breeders overlook, like having access to sexed semen when everyone else is still using conventional.

Brookview Tony Charity-widely hailed as the greatest show cow of all time-claims the Supreme Champion title at World Dairy Expo, setting a standard for genetic excellence and show ring dominance that breeders still chase today.

From Foundation Sires to Genomic Revolutions

Thoroughbreds and dairy cattle traced their excellence to foundational breeding decisions centuries ago. The Thoroughbred originated from three foundation stallions that forever transformed horse racing – the Byerley Turk, Darley Arabian, and Godolphin Arabian. These three sires established the genetic building blocks for all modern Thoroughbreds, with approximately 95% of today’s racehorses tracing back to the Darley Arabian through the male line.

Similarly, the dairy industry evolved from famous herds like Round Oak Rag Apple Elevation’s breeding program or the famed Hanover Hill prefix. The progression moved from visual selection to the data-driven breeding programs we know today – from eyeballing udders on the Guernsey farm road to studying genomic predictions on your smartphone during morning milking.

The real game-changer for both industries? Genomics.

Since sequencing the horse genome around 2006, Thoroughbred breeders have transitioned from traditional pedigree methods to more targeted approaches using genetic markers. The dairy industry, however, has embraced genomic technology with unprecedented enthusiasm and coordination, becoming to genetics what the rotary parlor was to milk efficiency.

Why This Matters for Your Operation: Implemented in 2009, genomic selection has revolutionized dairy breeding by doubling genetic gain. “From 2005 to 2010, the average gain in Net Merit $ was $40.33 per year. That annual gain doubled to $79.20 per year from 2016 to 2020 as the benefits of genomic selection were realized.” This doubling represents one of the most significant advancements in agricultural breeding history – and yet many breeders still haven’t fully leveraged its potential, like having a TMR mixer but still throwing silage over the fence.

***Citation storms home to win the 1948 Kentucky Derby by a commanding margin-an iconic moment in racing history and a testament to the power of elite genetics.***

Elite Sires: The Game-Changers

Certain standout sires have transformed their respective breeds in both industries through exceptional genetic contributions. These genetic titans don’t just produce champions – they establish dynasties that dominate for generations, like the difference between a farm with a consistent 30,000-pound herd average and one struggling to break 20,000.

Thoroughbred racing has Tapit, a true genetic powerhouse. “Tapit broke the single-season progeny earnings record for a North American sire in three consecutive years (2014-2016).” As a “great patriarch,” Tapit has sired over 100 graded stakes and 32 Grade I winners, with progeny earnings exceeding $210 million.

In the dairy world, elite bulls like Farnear Delta-Lambda represent similar genetic goldmines for breeders seeking show ring dominance. As the Premier Sire of the International Holstein Show at the 2024 World Dairy Expo, Farnear Delta-Lambda has established himself as the go-to bull for producing champions on the colored shavings – the bovine equivalent of striking oil on your back forty. His daughters dominated the competition, leading to this prestigious title recognizing the bull whose progeny performed most successfully in the show ring.

But here’s the inconvenient truth: too many dairy breeders chase the hottest new genomic young sire without understanding how to build a genetic program with staying power. It’s like buying fancy sexed semen for your heifers but neglecting your transition cow program. The Thoroughbred industry teaches us that creating a genetic dynasty requires strategic thinking beyond single-generation success.

One of only 37 cows to ever claim Expo’s highest honor.

The Speed Gene: What We Can Learn from Single-Gene Discoveries

While dairy breeders focus on complex indices balancing dozens of traits, Thoroughbred breeders received a genetic gift in 2010 that transformed their industry: the discovery of the “Speed Gene.”

Research led by Dr. Emmeline Hill identified a specific genetic variation near the MSTN (Myostatin) gene that strongly predicts a Thoroughbred’s optimal racing distance. This single-nucleotide polymorphism results in three possible genotypes, each with distinct performance profiles:

C: C Genotype: Horses develop muscle mass earlier and excel at shorter, faster races (sprints)
C: T Genotype: The most versatile type, performing well across a range of distances
T: T Genotype: These horses possess greater stamina and are best suited for longer races

This breakthrough was immediately commercialized as the “Equinome Speed Gene Test,” allowing breeders to decide precisely which horses to breed and how to train them.

Why This Matters for Your Herd: While many genes influence most dairy traits, the Speed Gene example reminds us to stay alert for major genetic discoveries that could transform breeding decisions. Think of it like the A2A2 beta-casein gene – a single genetic trait that suddenly created premium milk markets and breeding strategies virtually overnight. Similar markers for crucial dairy traits like metritis resistance or feed efficiency may be identified as genomic research continues. The breeders who quickly adopt these tools will gain substantial advantages in the market, just like early adopters of robotic milking systems or activity monitors for heat detection.

Market-Driven Breeding Strategies: Know What Wins

Successful breeders in both industries recognize the importance of aligning breeding goals with market demands. For Thoroughbred breeders, this means understanding what characteristics buyers value.

“To profit in this industry, you need a clear strategy aligned with what buyers want. If you want to create foals that command high prices at auctions, you’ve got to think like a buyer and build a plan around that.” This market awareness extends to studying recent auction results, tracking bloodline preferences, and identifying emerging trends.

In the dairy show ring, similar market awareness is critical. Breeding for World Dairy Expo success requires understanding what judges reward and what traits create a lasting impression. The ideal champion combines structure, style, and the capacity for high production – the kind of balanced cow that looks as good on the colored shavings as she does on her DHIA records.

Here’s where many dairy breeders go wrong: they focus exclusively on either production metrics or show ring appeal without understanding how to balance both. It’s like having stellar component percentages or trouble-free calvings when you should be demanding both. The most successful breeders develop strategies aligned with specific market goals – commanding premium prices for show-quality genetics or maximizing lifetime production and component values in a commercial setting where PPDs (Predicted Producer Differentials) and component premiums drive your milk check.

This exceptional Holstein demonstrates the perfect fusion of elite breeding and meticulous preparation that creates a multi-year champion. Like the Kentucky Derby winners described in our article, Shakira represents generations of strategic genetic decisions culminating in show ring dominance on the colored shavings.

Genomics: Speed of Progress vs. Balanced Improvement

One significant difference between the two industries is their approach to generation intervals – the average age of parents when their offspring are born. Genomic selection has dramatically shortened generation intervals in dairy cattle breeding.

Research shows that generation intervals reduced significantly between 2009 and 2016, allowing for much faster genetic progress as elite animals are identified earlier and used for breeding at younger ages. This principle applies equally to both industries, though the dairy sector has leveraged it more aggressively through reproductive technologies like artificial insemination, embryo transfer, and in vitro fertilization.

Every dairy breeder should ask: Are you effectively utilizing these tools to accelerate genetic gain in your herd, or are you falling behind competitors who understand this fundamental principle? It’s like watching your neighbors install precision ag technology while you’re still using dead reckoning to apply fertilizer. The genetic gap widens every breeding season – measured in TPI, NM$, or LPI points directly affecting your bottom line.

Like elite dairy champions, Affirmed exemplified exceptional genetic merit combined with proper development and handling. His bloodlines through his sire Exclusive Native continue to influence Thoroughbred breeding, demonstrating how champion genetics create lasting dynasties – a principle equally valuable in dairy cattle breeding programs.

The Strategic Mating Advantage

Creating champions in either arena requires more than selecting elite genetics- it demands strategic mating decisions that complement strengths and address weaknesses. Successful Thoroughbred breeding involves matching stallions and mares with complementary characteristics.

“Choose stallions based on pedigree compatibility, not marketing or stud fees,” advises one bloodstock expert. This philosophy emphasizes analyzing how specific crosses might combine strengths and offset weaknesses rather than simply pursuing the most fashionable or expensive sires.

In dairy breeding, a similar approach applies. When aiming for World Dairy Expo success, breeders must evaluate their females honestly and select bulls that complement their strengths while correcting weaknesses. This might mean using a bull strong in mammary traits on cows with average udders or selecting for improved feet and legs when that’s a family weakness.

Why This Matters for Your Breeding Program: Many dairy breeders make the critical mistake of using the highest-ranked bull on all their cows, regardless of individual strengths and weaknesses. It’s like treating all your mastitis cases with the same antibiotic without culturing first. Inspired by Thoroughbred approaches, strategic mate selection involves analyzing how specific crosses might combine strengths and offset weaknesses. This method produces animals with the optimal traits needed for show ring success and profitable production.

For example, if your Goldwyn daughters have tremendous mammary systems but tend to lack power and substance through their front ends, mating them to bulls like Impression or Jabir that add strength and chest width could produce much more balanced offspring than simply using the current #1 TPI bull. This thoughtful approach beats random mating like protein premiums beat fluid milk markets.

When judges assess structure, style, and dairy strength, this is what championship excellence looks like.

Beyond Genetics: Preparing Champions for the Spotlight

Even with perfect genetics, neither a Kentucky Derby winner nor a World Dairy Expo champion is created by DNA alone. Creating a champion extends beyond genetic selection to include proper development and management.

In Thoroughbreds, this encompasses specialized nutrition, meticulously planned exercise regimens, and handling that builds confidence and athletic ability. Similarly, World Dairy Expo champions require extraordinary preparation beyond their genetic potential.

The development of young animals, proper nutrition during growth stages, expert fitting, and professional presentation all contribute to championship success. This means paying as much attention to your dry cow TMR formulation as you do to your lactating ration. It means perfecting heifer-raising programs that develop frames without overconditioning. For show animals, it means mastering the art of hair training, udder edema management, feed program timing, and professional clipping and fitting that makes good cows look great.

One veteran dairy breeder noted, “Even with elite genetics, there’s no substitute for hard work, keen cow sense, and a passion for perfection.” The best-bred animal in the world won’t reach its potential without proper development – just like the best robotic milking system won’t perform without appropriate maintenance and management.

American Pharoah surges ahead to victory in the 2015 Kentucky Derby-showcasing the elite genetics, athleticism, and preparation that ended a 37-year Triple Crown drought and set a new standard for breeding champions.

Balancing Show Ring Excellence with Functional Performance

While a Kentucky Derby winner needs one perfect two-minute performance, the World Dairy Expo champion represents years of productive life in the milking string. This fundamental difference highlights the importance of balancing extreme type with functional traits in dairy breeding.

The most successful dairy breeders recognize that true champions must possess exceptional conformation and the genetic foundation for production, health, and longevity. The ideal World Dairy Expo champion combines structure, style, and the capacity for high production – a cow that not only pins the blue ribbon but also fills the bulk tank.

Here’s a provocative question: Has pursuing extreme dairy character and show ring style gone too far in some breeding programs? When cows are so sharp, they look like they’ve been on a starvation diet, so something’s wrong with our selection criteria. The Thoroughbred industry’s relentless focus on performance rather than appearance offers a valuable lesson in breeding for function first. After all, a Ferrari might look impressive in the driveway, but a well-built pickup truck gets the farm work done every day.

Cutting Edge T Delilah, 2018 World Dairy Expo Supreme Champion, represents the pinnacle of strategic genetic selection. Like Kentucky Derby winners, World Dairy Expo champions embody generations of careful breeding decisions, combining elite bloodlines with balanced traits for both show ring appeal and functional performance. This moment on the colored shavings-draped in the prestigious Supreme Champion blanket-symbolizes what dairy breeders strive for: genetic excellence expressed in its most magnificent form.

Lessons from Both Worlds: What We Can Apply Now

Let’s distill the key strategies from Thoroughbred breeding that can transform your dairy breeding program:

Data-Driven Decisions: Like the Thoroughbred’s unwavering focus on race results, base your breeding decisions on comprehensive data rather than trends or marketing hype. A pretty picture in a sire catalog is worth less than solid proofs across multiple traits.
Strategic Mate Selection: Don’t just use high-ranking sires – select bulls that specifically complement each cow’s strengths and weaknesses. Mating a cow with excellent production but poor feet and legs to a bull that excels in mobility makes more sense than using the same “corrective” bull across your entire herd.
Elite Genetic Lines: Identify and intensify the influence of exceptional genetic lines, like how Tapit established a dynasty in Thoroughbred racing. When you find a cow family that consistently produces trouble-free, high-producing animals, double down on those genetics like you’d double down on your most profitable crop rotation.
Market Awareness: Align your breeding goals with specific market demands, whether show ring success, component production, or feed efficiency. If your milk processor pays substantial premiums for butterfat, your breeding program should reflect that economic reality – just as you’d adjust your cropping program based on commodity prices.
Generation Interval: Leverage genomics and reproductive technologies to accelerate genetic progress through shorter generation intervals. Using sexed semen on genomically tested heifers lets you turn generations faster than waiting to breed older cows – like harvesting a fast-growing crop three times versus a single cutting of a slower variety.
Balance Function and Form: Remember that even the most beautiful cow needs to be productive and healthy – performance must accompany appearance. The cow that wins Grand Champion at your county fair should be able to walk back to the barn, eat aggressively, and milk with the best of them, not just stand pretty for the camera.
Development Focus: Invest in your animals’ proper development and presentation, recognizing that genetic potential must be nurtured appropriately. The best genomic predictions won’t help if your calves face respiratory challenges from poor ventilation or your heifers are overweight at breeding – just as the best corn hybrid won’t perform in poorly drained soil.

What World Dairy Expo Can Learn from the Kentucky Derby’s Mainstream Magic

Let’s face the uncomfortable truth – the Kentucky Derby captures America’s imagination while the World Dairy Expo barely registers outside our industry bubble. Churchill Downs draws nearly 400,000 spectators annually (SIX Super Bowls’ worth of fans) and 16.7 million TV viewers who couldn’t tell you the difference between a yearling and a gelding. Meanwhile, the Expo remains our industry’s best-kept secret despite showcasing the world’s most elite dairy genetics. The difference? The Derby isn’t just marketing horses – they’re selling an experience that “transcends demographics” with equal appeal to bourbon-sipping traditionalists and TikTok influencers like Alix Earle.

World Dairy Expo openly admits they actively avoid marketing to the general consumer market – this event is all about dairy farming. There are many lessons we could learn from the Kentucky Derby. While Churchill Downs creates “cultural moments” with celebrity announcers like Simone Biles, non-alcoholic “Pony” mocktails for Gen Z, and fashion that dominates social media, we’re debating whether to let high schoolers take free pencils from our trade show booths.

World Dairy Expo has everything needed to captivate mainstream audiences. The colored shavings, legendary champions, multi-million-dollar cattle, cutting-edge genetics, and generational family stories are marketing gold – if we’d stop hiding them behind industry jargon and closed doors. One industry observer noted, “I’ve never seen such a sense of community as when I walked through the barns… It’s something you want to bottle up.” That’s the point – we must stop hoarding these experiences and start bottling them for larger consumption. Kentucky Derby organizers understand that “turning on the TV to see your favorite celebrity” drives curiosity about attending the event. If we want dairy farming to remain economically and culturally relevant, it’s time to steal their playbook before our industry becomes as obsolete as yesterday’s classification score.

Justify powers through the mud to victory at the 2018 Kentucky Derby, showcasing the elite genetics that made him the 13th Triple Crown winner in history. Like World Dairy Expo champions, his superior physical attributes and genetic excellence demonstrate how selective breeding creates exceptional athletes across species.

The Bottom Line

Whether at Churchill Downs or the World Dairy Expo, pursuing championship excellence relies on similar genetic principles applied in different contexts. By understanding how Thoroughbred breeders have created Kentucky Derby champions, dairy producers can refine their breeding programs for show ring success and profitability.

The genomic revolution has given dairy breeders unprecedented tools for genetic advancement – tools many in the Thoroughbred industry would envy. The question isn’t whether these technologies work; it’s whether you’re maximizing their potential in your breeding program. Are you still using conventional semen when your competitors are employing strategic combinations of genomic testing, sexed semen, and targeted embryo transfer?

For dairy breeders dreaming of leading the Grand Champion on the colored shavings at the World Dairy Expo, the lessons from Kentucky Derby breeding success provide a valuable roadmap. That championship dream can become a reality by leveraging genomic technologies, focusing on market-relevant traits, utilizing elite bloodlines, and implementing complementary mating strategies.

The path to breeding excellence may differ in detail between horses and cows, but the fundamental genetic principles that create champions remain remarkably consistent across species. With the right genetics, unwavering dedication, and a little show ring magic, that dream of standing in the spotlight on the colored shavings isn’t just possible – it’s practically inevitable.

Are you ready to rethink your breeding strategy and apply these cross-species lessons to create your next champion? The colored shavings await, and so does the profitable future of your dairy operation.

The Great Holstein Shakeup: How 16 Years Rewrote Breeding Rules

Monday, March 24th, 2025

How Holstein breeding flipped from show-ring beauty to farm profitability: The 16-year revolution that’s transforming dairy genetics forever.

<a href="https://rss.com/podcasts/the-bullvine/1954899/">E208 The Great Holstein Shakeup: How 16 Years Rewr | RSS.com</a>

Do you know what blows my mind? How completely different Holstein breeding looks today compared to just 16 years ago. Seriously. We’ve been digging through Holstein Canada registration data from 2008 to 2024, and wow—the transformation is nothing short of revolutionary. If you’ve been in the Holstein breeding industry for a while, you’ve lived through a significant rewriting of the breeding rulebook, whether you realized it or not.

“From a focus on high conformation or a two-lactation and culled cow to a four-plus lactation, healthy, fertile, self-sufficient, high fat yielding cow.”

Genetic Diversity: The Old “Super-Sire” Model Is Dead

Remember when everyone and their brother used the same handful of bulls? Back in 2008, if you walked into any barn in Canada, practically every seventh heifer was sired by DOORMAN, GOLDWYN, or BUCKEYE. I’m not exaggerating—these three bulls alone accounted for nearly 12% of all registered females!

Fast forward to today, and that concentration has completely collapsed. Now, you’d need to see almost twenty-two calves before finding one from a top three sire. That’s not just a tiny shift—it’s a significant rejection of how we used to think about breeding.

“DOORMAN alone had 12,165 daughters registered in 2008. That was enough to fill about 120 average dairy barns back then!”

Think about this: DOORMAN alone had 12,165 daughters registered in 2008. That was enough to fill about 120 average dairy barns back then! Today’s top sire wouldn’t even fill 80 Canadian barns. Breeders have gotten a lot smarter about spreading genetic risk across more bloodlines. And honestly? It’s about time.

From Pretty Cows to Profitable Cows

Remember when everyone was chasing those gorgeous, deep-ribbed, less fertile, and often less robust show cows regardless of what they cost to maintain? Those days are gone, my friend. The Holstein world, everywhere, has flipped from worshipping pretty cows to demanding farm-level profitable ones.

“The Holstein world, everywhere, has flipped from worshipping pretty cows to demanding farm-level profitable ones.”

Early on (2008-2012), we were all obsessed with proven conformation sires. Look at the top bulls from that era—they were selected almost entirely for their daughters’ appearance. Today, the smart money is on bulls that deliver a complete package: health, production, fertility, AND decent conformation.

Here’s something nobody talks about enough: Despite all our sophisticated genetic tools and 16 years of so-called “improvement,” total Holstein registrations haven’t increased. It makes you wonder if we’ve been spinning our wheels, doesn’t it? The fact that bulls like WESTCOAST ALCOVE have shown up recently tells me breeders are still hunting for that perfect balance between genetic progress and sustainability.

Genomics: Game-Changer or Over-Hyped?

When genomics hit the scene in 2009, it didn’t just change how we select bulls—it completely rewrote who benefits from genetic advancement. Gone are the days when only the most significant operations with deep pockets could access elite genetics. With over 6.5 million Canadian dairy animals genetically evaluated now, we’re seeing a true democratization of genetics. Universally, dairy farmers have access to the top hundred Total Merit Indexed sires with no holes and will produce tomorrow’s complete cow.

But let’s be honest for a second. Are we selecting the right traits? The dramatic shifts in sire usage patterns suggest many breeders weren’t entirely sold on those early genomic promises. And rightfully so—the correlation between genomic predictions and actual performance isn’t perfect. Studies show genetic correlation coefficients of just 0.36 for milk yield, 0.29 for fat yield, and 0.19 for overall type with longevity. I’m not precisely sure. Are they bets?

The most mind-blowing impact of genomics has been on generation intervals. Check out these numbers:

Selection Path	1980 (Years)	2009 (Years)	2016 (Years)	% Reduction (1980-2016)
Sire to Bull (SB)	10.4	6.1	2.5	76%
Dam to Bull (DB)	8.8	5.3	2.9	67%
Sire to Cow (SC)	7.3	5.8	4.5	38%
Dam to Cow (DC)	5.5	4.3	4.2	23%
Total	32.0	21.5	13.2	55%

“In 1980, genetic improvement took over a decade to move from one bull generation to the next. Now it happens in just 2.5 years!”

Can you believe that? In 1980, genetic improvement took over a decade to move from one bull generation to the next. Now, it has happened in just 2.5 years! That’s like going from sending letters by Pony Express to instant messaging. No wonder we’re seeing such dramatic shifts in sire usage—we’re cycling through and benefiting from genetic options at warp speed.

I’ve watched breeders get much more knowledgeable about genomic indexing over time. Instead of unthinkingly chasing the highest numbers, they use genomics as just one tool in a more sophisticated strategy. That approach will be crucial with the significant genetic base change coming April 1, 2025—PTAs for USA Holsteins are about to drop by roughly 750 lbs for milk, 45 lbs for fat, 30 lbs for protein, and 0.6 for PTAT. That’s going to shake things up!

Beyond Milk: The New Traits Taking Over

You’ve probably noticed breeders talking a lot more about novel traits recently. This isn’t just trendy chatter—it’s a necessary evolution to survive in tomorrow’s industry. Between 2016 and 2024, we’ve seen a massive surge in interest for polled genetics, A2A2 milk, milk solids yield, and health and reproduction-related traits that directly impact a farm’s bottom line.

Ignore these trends at your peril. The upcoming Net Merit index revisions will emphasize butterfat yield, feed conversion efficiency, and cow livability. These aren’t just fancy buzzwords—they’re traits that directly address economic and environmental sustainability. In other words, they will help keep farms in business.

Trait	Current NM$	April 2025 NM$
Protein	19.6%	13.0%
Fat	28.6%	31.8%
Feed Saved	12.0%	17.8%
Productive Life	11.0%	8.0%
Cow Livability	7.0%	8.0%
Udder Composite	7.0%	7.0%
Fertility	6.8%	6.8%
Heifer Livability	1.3%	2.0%

As you can see from this table, the emphasis on butterfat production has increased significantly in the latest Net Merit index, while protein has decreased substantially. This reflects current market trends and the growing economic importance of butterfat. The shift toward feed efficiency (Feed Saved increasing from 12% to 17.8%) also shows how the industry adapts to address rising feed costs and sustainability concerns.

Want to see why fertility traits suddenly matter so much? Take a look at these real-world numbers:

Trait	Mean Index	Standard Deviation	Records Analyzed
Conception Rate (CCR)	0.43	0.49	837,655
56-day Non-Return Rate (NRR56)	0.50	0.50	857,821
Calving Ease (CE)	1.06	0.27	259,042
Stillbirth (SB)	1.07	0.25	273,367
Gestation Length (GL)	278.36 days	6.18 days	258,611

A mean 0.43 sire cow conception rate? Yikes! That means the average Holstein needs multiple services to conceive. And that 56-day non-return index of 0.50. It tells us that too many cows are being bred to below-average sires and must be rebred within two months. No wonder fertility has become a hot selection priority—these numbers directly hit the pocketbook!

“Sire genetic merit for daughter fertility traits is improving rapidly in the dairy breeds, including the Holstein.”

Genetic selection is working. As Butler and others have shown, “Sire genetic merit for daughter fertility traits is improving rapidly in the dairy breeds, including the Holstein.” Thanks to genomics, we’re fixing fertility problems much faster than they initially declined when the priority traits in selection were milk yield and type. That’s something to celebrate over our morning coffees!

Power Shift: The End of Genetic Monopolies

The most fascinating change we’re seeing is the complete rebalancing of genetic influence across the Holstein population. In 2008, the top thirty sires used in Canada accounted for about 35% of all female registrations. By 2016, that dropped to just 22%, and the trend has continued.

This isn’t just a random statistic—it represents a fundamental power shift in dairy genetics. For decades, we rushed to use the “best” bulls, which narrowed genetic diversity and cranked up inbreeding rates. Finally, breeders are pushing back against that dangerous trend.

Trait	Heritability Estimate
Lactation Yield	0.46 ± 0.206
Birthweight	0.32 ± 0.181
Age at First Calving	0.19 ± 0.162
Calving Interval	0.14 ± 0.211
Age at Maturity	0.11 ± 0.136
Dry Period	0.11 ± 0.124
Days Open	0.09 ± 0.121
Lactation Length	0.04 ± 0.212

This table helps explain why milk production traits have historically dominated selection programs while fertility traits have been more challenging to improve. Traits with higher heritability, like lactation yield (0.46) and birthweight (0.32), respond more readily to selection pressure than low-heritability traits like days open (0.09) and lactation length (0.04). The introduction of genomic selection has been particularly valuable for these low-heritability traits, allowing for more accurate identification of genetically superior animals early in life.

Have you noticed more European bulls in AI catalogs lately? That’s no accident. While Canadian and American genetics dominated the early years of our analysis, we’re now seeing significant international representation. This global genetic exchange introduces fresh bloodlines to help fight inbreeding while delivering solid performance.

“We’re not just making small improvements—we’re correcting the whole course of the breed!”

What excites me is how selection based on genomics has rescued traits that were heading in the wrong direction. Research clearly shows that “genetic trends changed from negative or close to zero to positive or favorable” for traditionally difficult-to-evaluate traits like milking cow conception rate, productive life, and somatic cell score. We’re not just making small improvements—we’re correcting the whole course of the breed!

What’s Next? Innovative Breeding Strategies for Tomorrow

Based on everything we’ve seen over these 16 years, I’d bet my farm on several significant shifts in Holstein’s breeding strategies.

First, we’ll keep pivoting hard toward functional, health, and efficiency traits. The days of selecting primarily for production and type are over—sorry, not sorry! Modern breeding programs must balance these traditional traits with newer priorities impacting sustainability and profitability.

Second, A2A2 milk genetics will soon be the standard, not a specialty. Our data clearly show this trend, and industry forecasts agree, predicting “increased fat and protein yields, increased %Fat and a prevalence of A2A2” in the coming decade.

Third, new data and information resulting from new technologies and methodologies will continue to help accelerate genetic progress while addressing genetic diversity concerns. With 90% of Holstein registrations submitted electronically, our industry will have the infrastructure for sophisticated genetic management that balances progress and diversity.

Finally—and this one might ruffle some feathers—animal welfare traits like polled and healthy hoof genetics will increasingly drive selection decisions. Consumers care more about this stuff every year, and genetics that address welfare concerns will command market premiums paid by processors. Astute breeders are already positioning themselves for this shift.

The Bottom Line

What strikes me most about this 16-year journey is how dramatically the Holstein breeding philosophy has changed. We’ve collectively rejected the super-sire model in favor of genetic diversification, wholly transformed how we manage genetic resources and risk, and broadened our genetic focus beyond milk and type.

Canadian Holstein breeders, and I expect American breeders, have shown incredible adaptability through all this change. They’ve navigated the transition from traditional progeny-testing to genomic selection while embracing a more comprehensive view of what makes a profitable cow.

The data doesn’t lie—breeders use genetic information more strategically than ever. The winners in tomorrow’s dairy industry won’t be those unthinkingly chasing the highest numbers but those who skillfully balance genetics, economics, and consumer demands.

“The real question isn’t whether your breeding program will transform, but whether you’ll lead or participate in that transformation or be left to play catch-up or exit the industry.”

With genomic selection slashing generation intervals—from 10.4 years to just 2.5 years on the sire-to-bull path—genetic improvement will only accelerate from here. The real question isn’t whether your breeding program will transform but whether you’ll lead or participate in that transformation or be left to play catch-up or exit the industry.

What do you think? Are you ready for what comes next?

Key Takeaways

The Holstein industry has decisively rejected the concentrated “super-sire” model, with top three sire representation dropping from 12% of registered females to requiring 22 calves to find one from a top sire.
Genomic selection has revolutionized breeding by reducing generation intervals by 76% (from 10.4 to 2.5 years) on the sire-to-bull path, enabling faster genetic progress and trait improvement.
Selection emphasis has dramatically shifted toward functional traits, with the 2025 Net Merit index increasing emphasis on fat (31.8%) and feed efficiency (17.8%) while decreasing protein emphasis (from 19.6% to 13.0%).
Low-heritability traits like fertility are being improved much faster through genomic selection, addressing critical issues like the concerning 0.43 mean cow conception rate.
Future breeding strategies will increasingly incorporate welfare-oriented traits (polled, hoof health) and A2A2 milk genetics as consumer preferences drive market premiums for these characteristics.

Executive Summary

The Holstein breeding industry has undergone a revolutionary transformation over the past 16 years, shifting focus from aesthetically pleasing show cows to functional, profitable animals that remain productive for four-plus lactations. This paradigm shift rejected the “super-sire” model that once concentrated genetics (with three bulls accounting for nearly 12% of all registered females in 2008) in favor of greater genetic diversity and reduced inbreeding. Genomic selection has dramatically accelerated genetic progress by slashing generation intervals from over 10 years to just 2.5 years on the sire-to-bull path, while simultaneously democratizing access to elite genetics. Increasingly, breeders are prioritizing health, fertility, and efficiency traits over pure production and conformation, with upcoming Net Merit index revisions placing even greater emphasis on butterfat yield, feed efficiency, and cow livability. The industry is now poised for further evolution toward welfare-focused traits like polled genetics and enhanced hoof health as consumer preferences continue to shape breeding decisions.

Unlock the future of dairy farming. Ready to redefine breeding for 2028 and beyond? Discover strategies to enhance your herd’s potential.

<a href="https://rss.com/podcasts/the-bullvine/1825888">E105 Rethinking Balanced Breeding for 2028 and Beyond</a>

In the dynamic world of dairy farming, where tradition intertwines with innovation, balanced breeding emerges as a harmonious blend of artistry and scientific precision, forming the industry’s foundation.

In the early 1900s, pedigree balancing was the mainstay, much like a fabled chess game in which breeders strategically matched lineage and heritage, weaving the threads of future generations. Fast-forward to today and the landscape has transformed—it is not just about balance. It involves ensuring survival and achieving excellence in a rapidly changing global dairy industry, highlighting its evolution and the urgent necessity for modern breeding practices. Despite the advancements in current systems, many dairy farmers and industry professionals continue to rely on balanced breeding.

All this demands that dairy farmers and industry professionals question whether the notions of the past are sturdy enough to support tomorrow’s ambitions. By challenging historical breeding beliefs, they are urged to evaluate the efficiency of their present approaches. Are we breeding with future goals, or are traditional methods hindering our progress? Is it time to unravel the intricacies of balance in breeding as the industry confronts the silent revolution pushing dairy cattle breeding toward new horizons?

The Evolution of Dairy Cattle Breeding: A Century’s Journey from Pedigree to Precision

Time Period	Breeding Focus	Key Innovations	Challenges
1900s – 1930s	Pedigree Balancing	Lineage Documentation	Lack of Data
1940s – 1965	Phenotypic Data Utilization	Progeny Testing	Avoidance of Production-Type Mix
1965 – 1990	Production and Type Balancing	Trait Performance Analysis	Balancing 50:50 Production:Type
1995 – 2020	Total Merit Index (TMI) Ranking	Genomic Selection	Over-reliance on Historical Data
2020 – Present	Precision Genetics	Genomic Indexes	Need for Strategic Focus

The development of balanced breeding in dairy cattle has changed a lot over the past century.

Forging Foundations: The Art of Pedigree Balancing in Early 20th Century Dairy Breeding

In the early 20th century, North American dairy cattle breeders faced formidable challenges that shaped the beginnings of balanced breeding. From the 1900s to the 1930s, breeders relied on pedigrees and family lines, as they did not have organized farm data systems to help them make decisions. This emphasis on pedigrees paved the way for a breeding approach where intuition and historical wisdom were the cornerstones of decision-making.

Early breeders’ unwavering commitment was to maintain a balance among successful cattle families, ensuring the preservation of good traits by selecting proper lineages. Although this approach could have been more precise, it did help improve Holstein breed quality. By aligning family strengths and balancing bloodlines like Posch and Abbekerk, early breeders set the stage for what would later become more scientific breeding methods, underscoring the crucial role of experience in the field.

Deciphering Data: The Mid-20th Century Shift Towards Phenotypic Precision in Dairy Breeding

During the mid-20th century, dairy cattle breeding considerably changed using official phenotypic data. This shift happened when breeders started using accurate data to address common issues in Holsteins, like deep udders and low butterfat percentages. This data helped breeders make more accurate choices, moving beyond just using pedigrees to focus on measurable traits.

Still, there was a gap even with the focus on phenotypic data. Breeding often kept production traits, like milk yield and butterfat, separate from type traits, such as udder depth and overall structure. Breeders could fix specific problems but still missed connecting a cow’s production abilities and physical features. As a result, breeding could improve one area while ignoring another, highlighting the need for balance in these practices.

Striking the Right Chord: The 1960-1990 Era of Balanced Breeding in Dairy Cattle

During the lively period between 1960 and 1990, dairy breeding focused on balancing production and type. This emphasis on balancing production and type highlights the industry’s focus on creating productive and structurally sound cattle.

One example was Master Breeder Cliff McNeil (Heather Holme), who practiced a unique method that left a lasting impact. His approach involved alternating breeding goals for each generation, focusing on milk production in one generation and physical traits in the next. This method prevented any single trait from becoming too neglected. McNeil’s technique not only made selecting sires simpler but also helped create balanced herds and set an example for the balanced concept of modern genetic strategies.

Reassessing the Metrics: The Paradox of Progress in the Late 20th Century Dairy Breeding

In the late 20th century, dairy cattle breeding changed dramatically. Breeders started using Total Merit Indexes (TMIs) to select sires. These indexes relied on past performance data. They made choosing sires easier and set clear goals for breeders. However, a closer look shows that while this was a step forward in some ways, there were also problems.

TMIs used past performance data but could often neglect to address future breeding goals. Breeders immediately focused on improving yields and sometimes did not include some traits important for long-term success. This was clear when herds experienced declining reproductive efficiency and shorter lifespans. High-production breeding overshadowed other key traits, like fertility and health, vital for successful dairy farms.

The rise of TMIs also meant breeders used their instincts less. Before, breeders had relied on their knowledge to make careful decisions. Now, they often follow ranking lists instead of using a deeper understanding of genetics, their herd’s genetic merit, and sire matching. This led to more uniform breeding practices but less creativity and personalization.

As the industry kept using TMIs, which placed as much as eighty percent emphasis on the combination of milk production and conformation, the problems with this approach became clearer. Breeders realized that relying too much on past data limited their ability to face new challenges and changing market conditions. The idea that combining instinct with science was the way forward began spreading across dairy farms, leading to the need to breed and select the ideal animal.

The Mirage of Balance: When Mediocrity Masquerades as Mastery in Modern Breeding

In today’s world, ‘balanced breeding’ often means something different from what was once expected. Animals marketed as ‘TMI Balanced’ can often be average or below the current breed average instead of exceptional for one or more critical heritable traits. This means they might not have noticeable problems but also lack standout traits that could significantly improve a herd. The real issue is that genetic progress slows down; it might also go backward while seeming okay because performance is only average.

Also, selecting too many traits at a time can spread efforts too thin, making it hard to see any real improvement in a farm’s productivity. Focusing on a few essential traits that make a financial difference is recommended.

Knowing where an animal stands in the population is very important. This is often shown as a percentage rank (%RK) of an index value and helps people understand the genetic value of a sire or female’s contemporaries. Breeders can use these rankings to make smarter decisions, focusing on improving their animals and herd instead of just maintaining it. This means moving past old ways and embracing data-driven methods, which are not just a key but the key to success in the future of dairy breeding.

Sculpting the Future: A Precision Revolution in Dairy Breeding

The future of dairy cattle breeding needs a shift towards precision and focus. For example, breeders should concentrate on traits like kappa casein content, feed efficiency, and animal welfare to improve profitability and product quality. Instead of trying to improve too many traits, breeders should concentrate on three or four key traits that are heritable and economically important. This approach can lead to greater genetic progress and more efficient farming.

Trait heritability plays a vital role in the success of breeding programs. If a trait, as measured, is not heritable, it will not help with genetic improvement. Breeders must understand genetic indexing and how to use advanced technology to make real progress. The future of dairy breeding is about measurable genetic changes rather than simple phenotypic observations.

Planning for the future of dairy breeding requires an innovative approach. Instead of relying on past methods like reactionary culling and mating choices, breeders should use modern genetic knowledge to meet current and future market needs. This forward-thinking approach will help create cattle that match today’s and tomorrow’s demands.

Future-focused breeding should aim for practical results, such as better human digestion of milk products with a trait like A2A2 beta-casein, improved efficiency through better feed conversion and less labor for animal care, and improved animal health and reproduction. These improvements should also consider animal welfare, environmental sustainability, and alignment with global goals.

This new way of selective breeding is like creating a symphony, where each chosen trait plays a vital role in forming a productive herd. The future of breeding in 2028 and beyond is about finding this balance to drive significant improvements in the dairy industry.

Still today, some breeders focus too much on pedigree and physical appearance, ignoring the powerful insights genetic data can provide. So, livestock breeding continues as historical methods meet new genetic technology.

Breeding for a New Dawn: Harnessing Strategic Traits to Innovate Dairy’s Next Chapter

As the dairy industry enters a new era, choosing breeding traits is challenging and full of opportunities.

Kappa casein content is about to become essential. Kappa casein is the protein needed for cheese production, as it is key to the amount and quality of cheese. This change shows a shift towards breeding decisions that improve profits and product quality.

Feed efficiency is also an important trait that will be included in future breeding plans. With rising feed costs and environmental issues, optimizing feed conversion is crucial for saving money and being environmentally friendly.

Animal welfare and health is more than just doing what is ethically correct or giving lip service to genetically improving animal health. They are central to breeding programs focusing on sustainability and consumers’ wants. Cows that are healthier and well-suited to their environment produce more and live longer, reducing the need to replace them often and increasing farm profits. So, health, adaptability, and overall welfare traits are becoming more critical.

It is paramount to use DNA and factual data in breeding decisions. Genomic testing offers accurate details about inheritable traits, assisting breeders in making data-driven choices rather than relying solely on historical patterns. DNA accuracy allows breeders to predict breeding results more reliably, ensuring that chosen traits enhance the herd’s performance. Genetic indexes help identify and select animals that excel in important traits, avoiding a general phenotypic approach that can lead to, at best, average results. Thus, DNA and detailed data guide a superior and more forward-thinking dairy breeding strategy.

Navigating the Lifecycle of Dairy Excellence: Mastering Heifer and Cow Milestones for Optimal Breeding Success

In the complex world of dairy cattle breeding and management, understanding the key stages in the life of a heifer and a cow is crucial for success. A heifer’s journey begins with a trouble-free birth and a strong start, and her early days must be carefully managed to keep her disease-free and healthy. This heifer phase sets the path for a productive future; growth and fertility are essential milestones in deciding whether she can join the breeding herd.

As a heifer becomes a cow, the focus shifts slightly to include her performance high across lactations. Cows need smooth calving processes, reducing any issues during and after calving that could harm their health and productivity. During this stage, efficient feed conversion is key, as it affects the yield of milk solids and the economic efficiency of dairy operations. Achieving high feed conversion rates boosts milk solids production while lowering the environmental impact of dairy farming, aligning with modern sustainability goals.

Building environmental adaptability into heifers and cows can significantly improve their resilience to climate and management challenges. With industry advancements, the capacity of dairy animals to flourish in diverse environments will be crucial. Breeders and dairy operators should concentrate on crucial stages, investing in genetics and management practices that enhance health, reproduction, and adaptability. This ensures that each life cycle phase contributes to overall farm success.

In Pursuit of Greatness: Crafting the Elite Class in Dairy Farming Through Strategic Focus and Precision Breeding

Just like champions in sports or visionaries in business, the elite in dairy farming distinguishes themselves through unwavering focus and relentless dedication. In sports, top athletes, like Olympic champions, succeed through intense training and innovative coaching that builds on their strengths. Successful companies do well in business because they focus on the latest ideas, help their teams grow, and use their strengths wisely.

Prioritizing top-performing animals is a fundamental element in achieving success in dairy farming. These animals have the best genes, high production ability, and will be functional and healthy. Just like in sports and business, investing in elite dairy females can change herd breeding practices and improve the quality and efficiency of the farm. Farmers can ensure their herds do well in challenging and demanding markets by investing in elite genetic females.

But breeding top animals is not about luck. A careful selection process using the latest genetic studies and top indexing reports is needed to find those with the best potential. For example, in business, where data and research guide decisions, precision and forward-thinking are key to choosing breeding stock in dairy farming. So, recognizing and developing the best in the herd is not just a tactic—it is a powerful strategy, much like winning in sports or achieving top success in business.

Precision at the Crossroads: Mastering the Genetic Symbiosis in Dairy Breeding

Balancing the genetic potential in dairy cattle is a complex task, and this balance needs to happen precisely when mating is being considered. Instead of focusing only on choosing the right herd sire, the focus should be making wise choices during mating.

The moment of mating is crucial, as genetic traits can be matched to maximize the results. Choosing the best sire for each cow based on genetics can boost the development of desired traits. This approach allows breeders to plan for the offspring’s genetic makeup, enhances strengths, and minimizes limitations.

Smart mating choices use detailed data, such as genomics, functional traits, production performance, and herd goals. This helps breeders align their breeding goals with each cow’s unique features. This precision improves the chances of producing offspring that meet current market needs and future challenges. With strong decision-making practices, each generation can be better than the last, leading to an adaptable and forward-thinking breeding plan.

Prioritizing strategic mating over conventional sire selection positions dairy farmers as pioneers of innovation, aiding them in remaining competitive in a shifting landscape. Mastering the art of breeding at the moment of mating is the key to unlocking the potential for dairy excellence.

The Bottom Line

The dairy farming world is changing fast. The future belongs to those who look beyond old traditions. Breeders must now focus on precision genetic advancement instead of the old balanced breeding approach. It is time to aim for traits that make the industry more sustainable, efficient, and profitable. The breeders who embrace this change will lead the way, turning potential into success and setting a new standard for dairy cattle breeding.

So, ask yourself: Will you step forward with courage and vision or stay stuck in the past? Your decision will shape the future success of your dairy business.

Key Takeaways:

Balanced breeding has evolved over the past century, shifting from focusing on pedigrees to incorporating phenotypic and genetic data.
The middle of the 20th century saw a move towards using official phenotypic data to address challenges within the Holstein breed.
Balanced breeding through the late 20th century often meant striking a balance between production and type, though this approach had limitations.
Modern breeding practices sometimes prioritize “balanced” sires, potentially leading to average results rather than exceptional advancements.
Dairy farmers must focus on future needs rather than historical frameworks to enhance breed qualities for tomorrow.
Genetic indexes should be crucial in sire selection to ensure innovative breeding solutions.
The dairy industry’s future includes prioritizing traits like casein profiles, efficiency, health, adaptability, and sustainability.
Precision and a focused strategic approach to breeding can create an elite class of dairy cattle aligned with contemporary and future market demands.

Summary:

The landscape of dairy cattle breeding has dramatically evolved, initially relying on pedigree balancing in the early 1900s, shifting to phenotypic precision by the mid-20th century, and further transitioning to Total Merit Indexes (TMIs) by the late 20th century. Each era offered unique contributions yet often struggled to balance production and important traits like fertility and health. Today’s breeders are called to adopt precision and strategic trait selection in response to evolving market demands and animal welfare concerns. Emphasizing true mastery through strategic simplicity, the path forward lies in data-driven decisions and focusing on heritable, economically essential traits that will forge an elite class of dairy cattle.

From Milk Machines to Component Champions: How Genomics and Sexed Semen Are Remaking the Dairy Cow

Saturday, December 14th, 2024

Explore how genomics and sexed semen are turning dairy cows into component giants. Ready to rethink milk’s future?

<a href="https://rss.com/podcasts/the-bullvine/1801726">E88 From Milk Machines to Component Champions: How Genomics and Sexed Semen Are Remaking the Dairy Cow</a>

For years, the dairy industry was primarily focused on producing liquid milk. However, a significant shift is underway, with a growing emphasis on producing milk’s valuable components—butterfat and protein. This shift, far from being just a strategy change, is a boon for farmers. It meets the increasing demand for specialized dairy products and opens up new avenues for profitability. The introduction of advances like genomics and sexed semen has been instrumental in driving this change. These technologies, which allow farmers to enhance genetic traits for milk rich in components and to select herds with the best yields, are reshaping success in today’s dairy market.

Genomics and Sexed Semen: The Dawn of a New Era in Dairy Breeding

The introduction of genomics and sexed semen has dramatically changed dairy breeding. These cutting-edge techniques allow for a precise selection of traits, revolutionizing how we breed dairy cattle. Genomics studies the genetic code of cows, helping farmers choose genes linked to essential traits like milk production, butterfat, and protein. It’s like writing a dairy herd’s future, ensuring only cows with the best genetics pass on their traits.

Sexed semen has changed herd management by letting farmers choose the sex of new calves, favoring females. This reduces the number of male calves, which are less valuable in dairy and focuses resources on raising female replacements. This makes managing herds more efficient, matching herd potential with market needs for milk components.

The improvements from these technologies are significant. Genomic selection has doubled or even quadrupled the rate of genetic improvement in traits like fertility and production in breeds such as Holstein cattle. This advancement is mirrored in increased productivity, especially in milk components like butterfat and protein. Milk production has reached new heights, and it is now focusing more on boosting component yields. This approach values quality over quantity, aligning with industry trends seeking valuable products over mere volume.

The Complex Dance of Trait Correlations: Challenges and Opportunities in Dairy Breeding

The complex network of trait correlations in dairy cattle breeding offers both challenges and opportunities for breeders. Understanding these correlations is crucial for improving production while steadily maintaining herd health and efficiency. Notably, the nearly zero correlation between Predicted Transmitting Ability for Milk (PTAM) and Predicted Transmitting Ability for Fat (PTAF) implies that selecting more milk does not automatically mean more milk fat. This affects breeding goals, especially since milk components, like butterfat and protein, often drive profitability more than volume. Therefore, it’s essential to directly select these components to boost the production of premium dairy products like cheese.

The strong links among health traits—longevity, fertility, and disease resistance—underscore how interconnected cattle health and productivity are. Improvements in these traits elevate herd performance and operational costs, reducing the need for replacements and vet visits. Understanding these trait relationships is crucial in making wiser breeding decisions. It allows for a balanced breeding approach focusing on herd sustainability and productivity, ensuring that the industry moves forward sustainably and efficiently.

As efficiency becomes a primary focus, complications arise. Prioritizing production efficiency may mean compromising on physical strength. For example, cows with less body weight may have reduced maintenance costs. Still, they can be weaker or have poorer reproductive performance. Breeders must find a balance between efficiency and strength. Including thorough efficiency metrics and actual body weights in genetic evaluations could refine selection criteria, shaping a herd that meets modern demands without losing key traits.

From Fluid to Forte: Navigating the Component Revolution in Dairy

The change in milk from just a fluid to a component-rich product has reshaped the dairy industry. This is about more than just better nutrition; it relates directly to processing and profits. Since 2011, butterfat and protein have increased faster than milk volume. By 2023, milk production was up by 16.2%, but protein rose 22.9%, and butterfat jumped 28.9%. These numbers show a fundamental shift in what the dairy sector provides.

This change dramatically matters for cheese, one of the dairy’s biggest earners. In 2010, 100 pounds of milk made about 10 pounds of cheese. By 2023, with more butterfat and protein, that grew to almost 11 pounds. This shift not only improves efficiency but also promises increased profits. For dairy farmers, focusing on components is as important as fluid volume. Genomics and sexed semen help breed cows for better yield traits, boosting profits. With over 80% of U.S. milk used for manufacturing instead of drinking, aligning production with market needs is essential and promising for the future.

Companies need to innovate and adapt to higher component yields industry-wide. This is not just a suggestion but a necessity in changing industry trends. This means updating facilities, refining marketing, and building new partnerships across the supply chain. As composition trends in the industry continue to change, everyone must embrace these changes to stay relevant. This challenge pushes us to rethink milk’s future and adapt to the changing landscape of the dairy industry, inspiring us to take action and stay ahead of the curve.

Beyond the Gallons: Redefining Milk Production Reports for the Modern Dairy Era

The USDA’s Milk Production report has been the key measure of the nation’s dairy output for almost a hundred years. However, as the dairy industry changes, focusing only on milk volume misses essential details about today’s milk components. The report’s focus on liquid volume leaves out crucial information about butterfat and protein, giving consumers and manufacturers an incomplete picture.

Why is this important? Over 80% of U.S. milk is used for manufactured products like cheese, which depend heavily on these components and often have more economic value than raw liquid. To truly understand production trends, we must consider milk’s nutritional and functional components, not just the gallons.

The USDA report should focus more on component data, especially butterfat and protein, to improve accuracy and help farmers and industry professionals make better decisions. Precision is not just a luxury in today’s dairy industry; it’s a necessity. So, updating our metrics is vital to understanding and progressing in this rapidly changing market.

Shifting Paradigms: From Gallons to Gold—The Component Revolution in Dairy

For years, dairy farmers focused on making more milk, seeing it as a sign of success. But now, the focus is shifting to milk’s more valuable components: protein and butterfat. Consumers want dairy products like cheese, butter, and yogurt that need these components and are willing to pay more.

This focus on high-component milk is more profitable because the payment models pay more for solids like butterfat and protein than just the milk’s volume. It also fits well with the goal of farming more efficiently, as higher components mean more value from each cow, even if they produce less milk overall. This is especially helpful in areas where feeding and land costs are high, showing the need for strategies centered on milk components.

The future of the dairy industry depends on the value of these milk components. Understanding this shift is key for farmers who want to maximize profits and efficiency. Adapting to this change is more than just keeping up with the market and taking the lead.

Weighing the Future: Overcoming Challenges in Accurate Body Weight Integration for Dairy Breeding

Integrating actual body weights into genetic evaluations is a significant challenge for the dairy industry. This is mainly because data collection is complicated, and there’s resistance to changing how things have always been done. In the past, measuring body weight was considered difficult and expensive, so it was often estimated instead of measured. This has led to poor breeding decisions, focusing on high production while ignoring overall efficiency.

However, accurate body weight data could transform genetic evaluations. By choosing cows that produce well without being too heavy, breeders can create herds that need fewer resources. This cuts down on feed costs, a significant expense in dairy farming. Also, lighter cows that produce the same amount of milk can help lower the farm’s carbon footprint, meeting environmental rules and consumer demands for sustainable farming.

These changes lead to more efficient and profitable dairy operations and help farmers tackle modern challenges. Embracing this change could lead to a shift in focus, encouraging breeders to prioritize long-term efficiency over short-term production gains. Though complex, the benefits of using actual body weight data for better profitability and sustainability are significant.

Beef Meets Dairy: A Fusion of Innovation and Profitability

Sexed semen and genomics have also revolutionized the industry with beef-on-dairy practices. This innovative approach helps dairy herds achieve top-notch genetic quality. By using sexed semen, only the best females in the herd reproduce, while the others are bred with beef semen. This strategy boosts the quality of dairy replacement heifers. It increases the value of other offspring by crossing them with beef breeds.

“Beef on dairy has changed the industry, helping dairy farms make more money by tapping into beef markets while keeping high-quality dairy genetics.”

The advantages of beef over dairy are many:

Better Genetic Selection: Genomics helps farmers pinpoint and keep the best cows in the herd for future dairy production.
More Revenue Sources: Producing beef calves along with dairy calves lets farmers earn from the beef market, diversifying their income.
Lower Carbon Footprint: A more efficient herd using this dual-purpose strategy supports sustainability by reducing waste.
Efficient Resource Use: The combined approach ensures that farm resources are used to their fullest potential.

Beef on dairy represents an innovative evolution in breeding strategies and highlights a trend toward integrated farming. As the dairy industry faces economic and environmental challenges, these innovative practices are key to sustainable progress in agriculture.

The Unseen Dichotomy: Technology vs. Tradition in Modern Dairy Breeding

In today’s fast-changing dairy industry, sexed semen and genomics, when combined with in vitro fertilization (IVF), have brought another significant change. These advancements have nearly replaced the traditional role of the master breeder. Skills and animal care that were once central to dairy breeding are now overshadowed by the precision and predictability that modern science offers.

This shift creates a contrast: on the one hand, we are achieving genetic progress and efficiency at unprecedented rates, aiming for higher productivity with less environmental impact. On the other hand, we are losing the human element, the art of dairy breeding that has developed over centuries. Master breeders, known for their ability to understand animal lineages and potential, now operate in a world led by data and science.

For those trying to bridge this gap, the challenge is to integrate the wisdom of master breeders with the modern tools available. It’s about valuing tradition and innovation, ensuring that as technology advances, the fundamental knowledge of the breed remains intact. (Read more: Master Breeder Killed in Triple Homicide)

The Bottom Line

The dairy industry stands at a pivotal moment, driven by changes in breeding and production. Focusing less on sheer milk volume, the industry now aims to optimize components like butterfat and protein. Genomics and sexed semen have advanced genetics, paving the way for a future that boosts these components.

Yet, the complexity of traits and genetic indices presents challenges. Current milk production reports must be more accurate, highlighting the need for updated data that aligns with modern demands.

As we move through this transformation, we must ask: How will dairy stakeholders—farmers, breeders, policymakers—adapt to prioritize component growth? Can the industry work together to use genetic evaluations as a public asset, balancing sustainability and innovation?

Industry leaders must decide whether to push toward a more efficient, component-focused future in dairy. Can they balance profit with environmental care while satisfying a knowledgeable market? The journey ahead offers challenges but also opportunities for those ready to adapt.

Key Takeaways:

The integration of genomics and sexed semen has transformed the dairy industry from a milk production focus to component production, enhancing genetic progress and productivity.
Correlation constancy holds for most dairy traits, but PTAM and PTAF diverge, indicating distinct pathways for volume and fat breeding efforts.
Body weight’s negative correlation with Net Merit challenges breeders to balance efficiency with strength, urging the incorporation of actual weights in evaluations.
USDA’s Milk Production report, in its current state, offers an incomplete view of actual production dynamics, necessitating updates that reflect changing milk composition trends.
Component growth, exemplified by increased cheese yield, emphasizes the criticality of butterfat and protein tracking in assessing dairy productivity.

Summary:

The dairy industry is shifting from focusing on liquid milk volume to enhancing valuable components like butterfat and protein. Driven by advancements in genomics and the strategic use of sexed semen, this evolution has led to significant genetic progress, particularly in breeds like Holstein cattle, where productivity in butterfat and protein has seen remarkable gains—28.9% and 22.9%, respectively, by 2023. Despite these advancements, the USDA’s Milk Production report has lagged in capturing the accurate growth trajectory of milk components, providing an outdated view. With over 80% of milk now directed towards manufactured products, reports are urgently needed to accurately reflect these changes and capture the industry’s current economic focus. Redefining milk production reports and incorporating accurate body weight data in genetic evaluations can help create efficient, sustainable herds that meet modern environmental, economic, and consumer demands.

The Evolution of Dairy Cattle Breeding: From Famous Herds to Genomic Giants

Monday, October 14th, 2024

Dive into the history of dairy cattle breeding. How have renowned herds influenced today’s genetics? Uncover their role in modern dairy operations.

<a href="https://rss.com/podcasts/the-bullvine/1702615">E29 The Evolution of Dairy Cattle Breeding: From Famous Herds to Genomic Giants</a>

Have you ever considered how dairy cow breeding has evolved over the years? It has been an enthralling voyage from the renowned arenas of famous registered herds to the current ‘Genomic Index Age, a pivotal era where genetic giants now rule supreme. In the first part of the twentieth century, renowned herds supported by investor money supplied bulls from high-yielding dams, making them a desirable asset to small dairy producers seeking genetic improvement. Fast forward to today, when genetic evaluations (G.E.) and DNA-based indexing have redefined what it means to have excellent breeding stock. The days of commanding high prices only based on the name of the herd are over. Today, it is all about the science behind genetics for over fifty heritable traits.

Pre-WWII: The Golden Age of Elite Dairy Herds

This was a pivotal period that laid the foundation for the modern dairy breeding industry during this pivotal period. Before World War II, widely recognized dairy herds dominated the dairy breeding business. A herd’s prefix often defines its popularity, not the animals’ genetic merit. Significant investor funds often supported these herds, allowing them to retain high-quality buildings, personnel, and resources. Consequently, they became the preferred supplier for smaller dairy producers looking for high-quality herd bulls.

While these herds were lauded for individual cow’s exceptional milk and butterfat outputs, it is essential to note that their success was not simply due to any genetic improvement. Rigorous management procedures and enhanced nutritional strategies were critical in setting high production records. As a result, these herds made a relatively small genetic contribution to the larger dairy farming community. Their true advantage resided in their operational competence, which smaller farms aspired to replicate by purchasing bulls from these well-known herds.

Not all animals in these herds were evaluated for performance during this era, and animal marketing trumped genetic improvement. However, the number of purebred registered animals grew in the market share of all dairy cattle.

1945-1960: The Era of Aesthetic Excellence Over Performance

Between 1945 and 1960, many well-known dairy farms strongly emphasized ‘type’ over productivity. In this context, ‘Type’ refers to the physical appearance of dairy cattle, including body parts, stature/size, and show appeal. The objective was to improve these physical qualities, which often led to cows from these herds receiving showring rewards for their remarkable conformation.

While the emphasis on type resulted in cosmetically improved cows, it did not translate into any significant genetic advancement in milk output. Small dairy producers who depended on bulls from these prominent herds may have produced more attractive cows, but milk yield progress was flat. The need for beauty trumped the necessity for improved functional and yield traits.

New standards were set for ideal type (pictures and models) and yield (M.E.’s and BCA’s) traits during this era. For herds on official milk recording, it was required that all cows in the herd be recorded – a very positive step for genetic comparison procedures and accuracy. Animal genetic merit started to gain on animal marketing as the primary focus in owning purebreds. Milk producers increased their participation in breed and milk recording programs.

Mid-1960s to 1980: The Great Divide Between Type and Production

The mid-1960s to 1980 marked a watershed moment in dairy cow breeding, as genetic evaluation information (G.E. became available, especially for productivity traits such as milk output and fat content.

The refusal by the previously dominant display herds to include G.E.’s in their breeding efforts had implications. Their steadfast commitment to type while ensuring animals looked great in the showring resulted in these herds losing significance in genetic progress. And they also lost influence with breed organizations.

Meanwhile, some farmer-breeders saw the promise of accurate young sire sampling programs and accurate genetic indexes and experienced significant increases in herd production. These progressive farmer-breeders’ herds outperformed their type-focused competitors because they utilized production genetic information extensively.

As the breeding business shifted to a more science-driven approach, the gap between show-type herds and those focused on production efficiency grew. Farmer-breeders began to see the importance of using daughter-proven A.I. sires with robust genetic indexes, leaving conventional display herds needing help to retain their prior leadership role. This transition from type to production efficiency marked a significant shift in the industry’s approach to breeding.

During this time, extensive industry-supported research into genetic evaluation procedures and breeding strategies revolutionized the dairy cattle breeding industry. Leadership in genetic improvement started to shift from breeds and prominent herds to artificial insemination organizations. Purebred registered herds on milk recording and type classification programs made moderate genetic progress during this period.

Post-1980: The Revolutionary Impact of Genetic Evaluations

Post-1980, the dairy industry witnessed a revolutionary impact of genetic evaluations. Dairy farmers saw significant advances in the genetic merit of their herds by using assessment tools, including milk recording, type classification, young sire sampling, and elite proven sires. These tools transformed dairy cattle breeding on a monumental scale, leading to profound changes and advancements in the industry, especially for yield traits and mammary systems.

With the advent of genetic research, an expansion in data for new heritable traits, and enhanced genomic evaluation procedures, the dairy cattle breeding industry entered a new era. By the 1990s, the accuracy of genetic assessments had significantly improved, and total merit indexing (TPI, NM$. LPI, JPI, …) became widely used. A.I. sire selectors began to rely heavily on data-driven criteria to find bulls with significant genetic potential. These developments significantly departed from the earlier twentieth-century emphasis on phenotypic features, including type and showring characteristics. The gap in cow productivity widened between show-type herds and production-oriented farms, highlighting the importance of these new tools in driving genetic progress.

The disparity in breeding practices became even more pronounced when farmer-breeders using (post-2008) genomic assessments for total animal merit outperformed those depending on the 1970s breeding philosophy of 50% type and 50% milk yield. This shift in the industry landscape was a wake-up call, as it demonstrated the competitive advantage of genetic indexes in predicting future production performance. The mold had been broken, and this new approach gave farmer-breeders a clear edge in production efficiency and total genetic quality.

Have you seen a change in your breeding practices?

Focusing on genetic indexes rather than pedigrees from well-known prefixes has dramatically changed the breeding business. Many of today’s top-performing herds were among the first to use genomic testing. In today’s competitive dairy breeding market, it is apparent that post-1980 innovations considerably changed dairy animal breeding techniques.

The Era of Genomic Giants: The Modern Landscape of Dairy Cattle Breeding

Fast-forward to the present time. DNA indexes have become the starting point in animal selection decisions for breeders regardless of their trait priority: type, production, fertility, health, or functionality. For many traits, the age of genomic giants has firmly established itself. Seventy percent of dairy breed pregnancies are the result of using high total merit index genomic indexed bulls. This change demonstrates the decreased value farmer-breeders place on established superior daughter-proven sires 30-40 years ago. Acceptance and wide use of DNA information have replaced the questioning and skepticism of 2008 regarding genomic indexing. Breeding decisions today balance traits of most importance, as well as the accuracy of indexes and plans for future farm viability and sustainability.

The commercial paradigm for flourishing breeding herds has shifted dramatically. The days of high-income returns based only on a renowned prefix in a pedigree are over. Also, there is a selection for just one or two traits and long generation intervals. It is now all about high DNA-determined genetic merit for both males and females. Herd breeding strategies aim to produce high-indexing heifers. Dairy-sexed semen is increasingly utilized to control the size of the heifer herd, and there is a new revenue source from crossbred, half-beef calves. Lower-indexing cows and heifers are often implanted with elite embryos, guaranteeing maximum genetic improvement. The business of dairy cattle breeding is increasingly dynamic and financially based.

Lessons from Sheffield Farms: When Show Wins Don’t Translate to Genetic Legacy

In May 1960, my family bought my grandfather’s dairy farm, a watershed point in our lives. At the same time, Sheffield Farms from St George Ontario, a well-known display herd, held their dispersal auction. Despite my developing interest in Holstein breeding, I did not attend the sale 50 miles away due to our pressing need to complete a new milk house. Sheffield Farms, known for its multiple show victories, sold cows for an average of CA$3,152 (equivalent to CA$33,506 in 2024) and one for an astonishing $22,000. At the time, the typical milk cow sold for just $325.

Twenty years later, curiosity prompted me to investigate the progeny of Sheffield Farms’ show-winning herd. To my astonishment, none of the top sellers at that auction had significantly affected the Canadian Holstein breed. The sole exception was a heifer calf sold for $4,500, which produced several show-winning daughters before fading into oblivion.

This analysis was eye-opening. It proved that the perceived value of a well-known display herd only sometimes converts into long-term genetic influence. What was genuinely important was not the herd’s show success but the herdsman’s skill to offer animals for competition. This insight highlighted a fundamental point – genetic examinations are significantly more critical than showring awards when planning for long-term genetic advancement.

The Sheffield Farms’ Sale significantly impacted my views. As the dairy cattle industry entered the age of comprehensive genetic studies, it became evident that young bulls with high-performance indexes had a much more significant influence on the breed than older, established bulls bred for show success.

Have prominent registered Holstein herds made a meaningful contribution to genetic improvement? This issue is worth considering, particularly recent advances in dairy cow breeding. Historically, renowned herds enjoyed status, were shown in glossy ads, won contests, and sold for high prices. However, their contribution to genetic improvement becomes less evident as we look deeper. Genetic evaluations (G.E.) and genomic testing have transformed the sector in recent decades. Young bulls with high-performance trait indexes have significantly influenced genetic progress and will result in enhanced milk output, improved efficiencies, increased overall herd health, improved female reproduction, and improved functionality of animals. While traditionally bred registered herds still exist, their leadership role has been replaced by high-merit genomic bulls, now the trend leaders.

Comparative Analysis: Canada, USA, and the World

In Canada today, the method of breeding dairy cows has heavily embraced genomic studies, with most breed advancements based on DNA indexes. Canadian breeders have swiftly embraced high LPI genomic bulls, resulting in a contemporary marketplace dominated by performance-based selection measures. This forward-thinking mindset guarantees that the genetic merit in Canadian herds continues to flourish, with a growing split from once famous show-type herds.

Across the border in the United States, the scenario is quite similar, with minor regional variances. American dairy producers depend heavily on genetics, with many solely favoring productivity attributes. The presence of proven cow families and high-performance genomic sires in marketing reflects a delicate balance of history and modernity. Nonetheless, using modern genetic data is critical for making considerable genetic advancements. Individual breeders have a significant impact, especially those who can capitalize on high-index progeny and cutting-edge genetic research. Breeding herds often have groups of females with high genetic merit for milk solids yield, ideal breed type, or animal functionality to serve the industry’s evolving goals.

Looking at the worldwide scene, the trend toward genetic-based selection is consistent, while the amount of acceptance differs. Countries like Denmark and the Netherlands have pioneered genomics, quickly incorporating it into breeding efforts. This shift has yielded herds with excellent genetic value and impressive performance measures. In contrast, despite increased interest in genomics due to its promising results, conventional breeding procedures continue to be used in some regions worldwide.

So, how does this impact your personal breeding decisions? The evident message is the importance of genomic assessments and the high total genetic merit genomic bulls are rapidly advancing genetic improvement. If your breeding program continues to emphasize single or two-trait-focused selection, you should reconsider your approach. Consider how incorporating genomic information can improve your herd’s output, health, and overall performance. By matching your strategy with global trends, you can keep your herd competitive and profitable in a constantly changing dairy cattle breeding business. Setting your breeding goals is paramount to your dairy enterprise’s future.

The Bottom Line

The evolution of dairy cow breeding has moved to the tools of herd performance recording, data analysis, benchmarking, genetic research, identification of top females, and extensive use of elite genomic sires from the prior dominance of renowned registered herds. Historical patterns reveal that, although show-winning herds historically dominated, their genetic contributions fell short of their aesthetic attractiveness.

Genetic progress has always depended on progressive breeders capturing increasing data and providing it for industry analysis and use.

With the introduction of genomic assessments and the rising precision of genomic data, dairy producers today have unrivaled tools for driving genetic innovation and improving profit. As DNA indexing grows, breeders will make improved breeding decisions, resulting in calves with higher genetic values. However, this is about more than just cutting-edge technology. It is about incorporating these improvements into practical breeding tactics.

So, where are we going from here? Every dairy farmer and breeder must carefully evaluate their breeding practices. Are you using the most recent genetic data? Do you prioritize traits that will sustain your herd in the long term? The answers to these issues will influence individual enterprises’ success and the future of dairy farming.

As the industry continues to evolve, one thing is sure – a combination of careful research and practical breeding will drive the next age of dairy cow greatness. Preserving profit-focused traditions and embracing developments that provide actual, long-term advantages is essential. Dairy cow breeding’s future depends on all dairy industry stakeholders’ capacity to adapt, develop, and strive for genetic perfection.

Key Takeaways:

Pre-WWII, elite herds dominated with investor-backed ventures that set the standard for breeding quality.
In the mid-20th century, aesthetics often precede genetic productivity in herd priorities.
The advancement of genetic evaluations (GEs) marked a turning point, particularly from the mid-1960s to 1980.
Post-1980, the focus shifted decisively towards production enhancement using sophisticated GE methodologies.
Today’s breeding practices are dominated by genomic giants, with 70% of pregnancies resulting from high TMI genomic bulls.
“Famous” herds now rely less on legacy and more on proven performance metrics and DNA indexes.
The story of Sheffield Farms illustrates how historical show successes may not ensure lasting genetic impact.
The comparative landscape of dairy cattle breeding reflects differing influences between geography and breeder philosophy.

Summary:

This article tracks the transformation of Dairy cattle breeding from the pre-WWII era to contemporary practices, highlighting the changing influence of famous registered herds. Initially, elite herds were valued for breeding stock provision, yet post-WWII, they prioritized aesthetic traits at the expense of production improvements. As genetic insights solidified by the 1980s, the prominence of show herds waned, paving the way for genomic evaluations that reshaped modern breeding strategies. Presently, high-index genomic bulls surpass the historical impact of these herds. The article critiques the actual genetic influence of these renowned herds, drawing comparisons between practices in Canada, the USA, and globally. Examples like Sheffield Farms demonstrate that achieving show success does not necessarily correlate with long-term genetic legacy, critically examining past and present breeding paradigms.

Yet, in our unwavering pursuit of better genetics and maximum yields, have we potentially jeopardized the health and well-being of our dairy herds? As industry stewards, we must approach this critical issue with uncompromising vigilance. This essay discusses health features in dairy cow breeding and encourages dairy producers to reconsider their objectives and approaches. From disease resistance and lifespan to fertility and ease of calving, we’ll examine how these characteristics affect your dairy’s production, ethical criteria, and economic sustainability. Before digging further, one must ask: what are health qualities, and why are they important? How should these features be included in a contemporary, ethical dairy breeding framework? Your choices and actions may significantly impact the health and welfare of your dairy herds. Please reflect on your activities and envisage a new future for dairy farming, one in which health qualities are central to your operations, promising significant economic gains that can enhance your business’s profitability.

Understanding Health Traits in Dairy Cattle:

Understanding health features in dairy cattle necessitates thoroughly examining the many variables that impact bovine health and well-being. These health features include a variety of criteria, including disease resistance, which refers to cattle’s capacity to fight or recover from infections without requiring significant medical intervention. A high level of disease resistance can significantly reduce the occurrence of common illnesses like mastitis, thereby improving the overall health and productivity of your dairy herd. The somatic cell count (SCC) is vital since it indicates milk quality and udder health. Elevated SCC levels typically indicate the presence of mastitis, a common illness in dairy cows. This impacts the cows’ health and the quality of their milk. Reducing SCC is critical for enhancing both milk quality and animal health.

More than 60% of dairy producers now consider health features in their breeding selections. This is a substantial change in the business, suggesting a growing appreciation for the relevance of health attributes in dairy cow breeding. The incidence of mastitis, or the frequency of mastitis infections, is another important health factor. Mastitis prevention is critical for herd health, maximizing production rates, and ensuring financial stability.

Metabolic health and fertility are both critical components in successful breeding operations. Metabolic health maintains the balance of physiological processes, while fertility directly influences reproductive success, herd sustainability, and farm scalability. Longevity, representing dairy cattle’s lifetime and productive period, assesses general health, disease resistance, and adaptation. Cattle that are resistant to mastitis or lameness tend to live longer. Dairy farmers who properly grasp these health qualities are better able to combine high milk outputs with functional traits associated with adaptability, welfare, and resilience—a need in today’s developing dairy sector.

Understanding Health Traits for Herd Management:

Exploring this critical subject, the link between health features and herd management becomes apparent. As a dairy farmer, it’s your responsibility to prioritize health as the first goal. The welfare of your cows is not just an ethical issue but also a foundation for your farm’s commercial sustainability and profitability. By understanding and managing health traits effectively, you can be proactive in ensuring the productivity and well-being of your herd.

Furthermore, breeding for health features considerably improves the herd’s resilience. Approximately 50% of dairy cow problems are genetic. Robust cows have increased tolerance to the infections that plague agricultural areas, reducing the frequency and severity of debilitating ailments. This immediately boosts the dairy farm’s profits. Failing to include health features in breeding techniques risks the agricultural enterprise’s economic survival.

Prioritizing health features improves cattle well-being while increasing farm output and profitability. However, it is crucial to understand that the procedure may include inevitable trade-offs or problems. Should dairy farming experts prioritize health features in their breeding programs? Such a focus improves our cattle, enhances our companies, and boosts the sector.

Economic Impact of Health Traits:

Consider the severe financial consequences when dairy cattle’s health features are impaired. Specific health abnormalities cause significant economic disruptions on dairy farms, primarily by influencing key factors, including milk outputs, culling rates, treatment costs, and overall reproductive efficiency. Can you understand the depth of such economic upheaval? Genetic selection for health qualities may save veterinarian expenditures up to 30%. Let us examine this subject more attentively. Consider a dairy farm where existing health concerns cause a decrease in milk yield. As a result, these health issues need expensive treatments, which raise veterinarian costs—a tremendously unfavorable and onerous condition for any dairy farm. Wouldn’t you agree?

Secondary economic consequences include decreased reproductive efficiency, which slows herd growth rates and, eventually, limits milk production capacity. These circumstances burden the farm’s financial resources, significantly reducing profitability. Improving health features may boost milk supply by 10- 25%. But what if we reversed this situation? What if we made purposeful steps to improve the health features of dairy cattle? Isn’t this an issue worth considering? Improved health features might significantly reduce veterinarian expenditures, easing economic stresses. However, realizing that this may need some upfront expenses or fees is crucial.

Preventing diseases would minimize milk production losses, opening the door to enhanced economic success. Cows with more significant health features generate higher-quality milk containing up to 15% more protein. Furthermore, breakthroughs in health features may extend cows’ productive lifespans. This eliminates the need for early culling and increases herd profitability over time. Spending time, effort, and money on enhancing health features may provide significant economic advantages to dairy farms. It is critical to examine the long-term benefits of these investments.

Genetic Selection for Health Traits:

In the fast-changing dairy business, the introduction of genetic selection methods, notably Estimated Breeding Values (EBVs) and genomic selection, represents a significant opportunity for farmers. These techniques allow you to select and propagate cattle with better genetic qualities, particularly health aspects. This not only improves breeding operations but also promises significant economic benefits, giving you a reason to be optimistic and motivated about the future of your farm.

EBVs decode cattle genetic potential, revealing animals’ hidden skills regarding their offspring’s health and production. This essential information enables farmers to make educated decisions, improving the overall health of individual cattle and herds. The advent of genomic selection ushers in a new age of breeding technology, diving deeply into the inner elements of an animal’s genetic architecture. Genomic prediction allows for the exact discovery and use of critical DNA variations that anticipate an animal’s phenotype with unprecedented precision and dependability, considerably beyond the capabilities of older approaches.

The combined use of these genetic selection approaches has transformed breeding programs worldwide, pushing the search for improved health qualities in dairy cows. Identifying genetic markers connected to improved health features and smoothly incorporating them into breeding goals, which was previously a substantial problem, has become an opportunity for further improvement. This thorough attention to health features improves animal well-being and increases their resistance to disease risks.

Selection Indexes in Breeding Programs

Beyond single feature selection, the complex domain of selection indexes offers a balanced improvement of genetic value. Preventable illnesses account for around 40% of dairy cow mortality, underscoring the need for such comprehensive measures. Selection indices promote overall genetic development by assessing each trait’s unique quality against its economic value and potential genetic benefits. This technique goes beyond isolated changes, generating cumulative improvement across productivity and health qualities while ensuring that each trait’s costs and benefits are matched.

Globally, breeding initiatives are changing toward pioneering features like disease resistance, animal welfare, longevity, and even methane emission reductions. This more extensive approach predicts a future in which animal agriculture progresses from just economic to sustainable and ethical, with a strong emphasis on health features. The financial calculation is carefully addressed to ensure that the costs and benefits of each attribute are balanced.

Europe, a pioneer in this field, is pushing the boundaries of genetic selection for these cutting-edge features, even while worldwide acceptance remains restricted. This poses an important question: will we use the chance to improve the performance of breeding programs by using more extensive and innovative selection indexes?

Heritability of Health Traits

Understanding the heritability of health characteristics is critical in dairy cow breeding. Heritability estimations reveal the fraction of genetic variation that contributes to the observed differences in these qualities among individuals. According to research, heritability estimates for handling temperament features in dairy cattle are relatively high, indicating the importance of genetic variables. As a result, these qualities play an important role in complete multi-trait selection programs, with the potential to improve cattle temperament during handling and milking.

The heritability estimates for maternal and temperament qualities range from low to moderate, indicating a good opportunity for genetic improvement via selective breeding. Modern breeding programs have focused on the genetic examination of health features, using contemporary approaches like likelihood and Bayesian analysis to estimate exact heritability. These are essential for maximizing herd health and production.

While genetics are essential, environmental and managerial variables must also be addressed. Even if a cow is genetically inclined to excellent features, adequate management may prevent it from failing. As a result, the integration of gene selection and best practices in livestock management is critical. How can industry experts use cattle’s genetic potential to increase dairy output and improve animal welfare? As we better understand the complex interaction between genetics and the environment, the answer to this question will define the dairy industry’s future.

Balancing Health Traits with Productivity Traits:

Dairy producers have a recurring issue in balancing the economic imperatives of high milk output and the overall health of their cows. Can these seemingly opposing goals be reconciled to provide mutual benefits? The unambiguous answer is yes. One must examine the complex interaction between dairy cattle’s health and productive attributes to understand this. Undoubtedly, increasing milk output is critical to profitability in dairy farming. However, focusing just on production qualities may mistakenly neglect cow health and well-being, jeopardizing sustainability and herd productivity.

Addressing this complicated dilemma requires consciously incorporating health features into breeding choices. Dairy producers may adopt a more holistic method for choosing ideal genetic combinations by equally weighing health robustness and production qualities. Emphasizing traits such as adaptation, welfare, and resilience broadens breed selection criteria, fostering a more balanced and resilient herd. Optimizing animal health cultivates a sustainable future in which high productivity is achieved without sacrificing essential health traits.

For dairy producers who want to develop a sustainable and profitable enterprise, combining health qualities and production must go beyond lip service and become the cornerstone of successful farming. This breeding method represents a deep awareness of the interrelationship of health and profitability, anticipating a farming future that preserves the integrity of health features while maintaining high production in dairy cattle.

Considerations for Breeding Programs:

Adding health features into breeding plans requires a cautious and methodical approach in dairy cow breeding. These factors must be founded on the dairy producer’s individual management goals, environmental circumstances, and market needs. Isn’t developing a tailored and context-specific approach for managing breeding programs necessary?

Furthermore, advances in genetic evaluations are changing our approach to health features in cow breeding since these programs emphasize genetic assessments for health characteristics. Interesting. Isn’t it true that, although some breeding programs have made significant strides in integrating these qualities into their goals, the path to complete improvement is still ongoing? Genetic improvement techniques strive to maximize selection contributions while minimizing inbreeding. Balancing genetic advantages with the negative repercussions of inbreeding is not something to take lightly. Conscientious dairy producers use mitigation strategies, such as mating software and extension professional advice, to conserve genetic variety while assuring continual genetic progress. Aren’t these tactics essential for preserving genetic diversity while making steady evolutionary progress?

Establishing more complex and productive breeding programs relies on a pragmatic approach to animal breeding that prioritizes animal welfare. The redefining of selection indices and breeding objectives is becoming more critical, requiring incorporating qualities associated with animal welfare, health, resilience, longevity, and environmental sustainability. Thus, it is evident that dairies’ long-term viability depends on breeding goals that improve animal health and welfare, productive efficiency, environmental impact, food quality, and safety, all while attempting to limit the loss of genetic variety.

Collaboration with Breeding Experts and Genetic Suppliers:

Strong partnerships with breeding specialists, genetic suppliers, and veterinarians unlock a wealth of in-depth expertise, giving dairy producers tremendous benefits. These stakeholders provide access to critical genetic data, fundamental breeding values, and cutting-edge genomic techniques for health trait selection. However, it is vital to question whether we are leveraging this enormous pool of experience.

Collaboration with industry experts undoubtedly leads to a more specialized and successful breeding plan that addresses your herd’s health and production requirements. Nonetheless, the interaction between farmers and consultants goes beyond selecting the best breeding stock and treating illnesses. A dynamic and ongoing discussion with these specialists may aid in the early detection of possible problems, breed-specific features, and preventive health concerns. Consider inbreeding, for example. Are we completely aware of the hazards connected with it, as well as the various mitigation strategies? Have we optimized the use of mating software systems, using the expertise of extension professionals to guide these efforts?

Recent advances in genetic testing have created tremendous potential for selective breeding to treat congenital impairments and illnesses. Here, too, close contact with industry specialists is essential. But how often do we push ourselves to keep up with these advancements and actively incorporate them into our breeding programs? Is the secret to a healthier and more productive herd within our grasp, requiring only our aggressive pursuit of these opportunities?

The Bottom Line

The relevance of health qualities is prominent in the great mosaic of dairy cow breeding. This initiative reflects an ongoing journey of exploration, understanding, and application. Our joint responsibility is to use the knowledge gained from previous experiences, moving us toward a future that offers more profitability and higher ethical standards for all stakeholders.

The Perfect Height: Why Your Holstein Cow Shouldn’t Exceed 60 Inches for Optimal Dairy Production

Monday, August 5th, 2024

Why keeping your Holstein cows under 60 inches tall boosts dairy production. Are you optimizing your herd’s conformation for maximum yield?

Years of prioritizing size and height have shown that the Holstein breed may have gotten too tall. In cow breeding, the prevalent thinking was “bigger is better.” Recent studies and statistics, however, show otherwise. While those above 60 inches need 10% more feed, Holstein cows under 60 inches have shown a 15% increase in milk production efficiency. Cows under 60 inches have a 25% longer longevity. Knowing the repercussions of height impacts various aspects of dairy production, including feed economy, barn space efficiency, and, most significantly, the health and longevity of the cow. By focusing on maintaining Holstein cows at or below 60 inches, small dairy farms may achieve various benefits that immediately enhance milk production and reduce veterinary costs.

The Balancing Act: Navigating the Trade-Offs of Breeding Taller Holstein Cows

Over the previous several decades, Holstein cow height has significantly increased due to selective breeding procedures to increase milk production and overall size. Although inherited factors are essential, other variables such as improved nutrition and more effective management tactics have also contributed. However, breeding taller Holsteins has significant trade-offs. Taller cows are more susceptible to various health issues, even if they reach maturity earlier and have better feed consumption and milk production. Shorter Holstein cows have a 20% lower incidence of metabolic disorders. Holstein cows over 60 inches had a higher incidence of lameness and 30% more calving issues. Smaller height Holsteins also have greater production efficiencies; cows under 60 inches had a 15% gain in milk production efficiency, a 12% higher conception rate, and a 25% longer lifespan. Breeders may achieve a balanced approach that benefits the herd’s health and longevity by prioritizing other factors, such as the mammary system and overall production oversize and stature. This all-around attentiveness improves animal welfare and boosts the dairy farm’s long-term profits.

Boosting Cost-Effectiveness on Small Dairy Farms with Holstein Cows Under 60 Inches

Dairy farmers might save money by maintaining a herd of Holstein cows under 60 inches. Improved feed efficiency is an apparent economic gain. Holstein cows above 60 inches use 10% more feed. Conversely, more tiny cows produce more milk while consuming less grain, cutting feed costs without compromising production. This efficiency is beneficial because feed accounts for many dairy farms’ operating budgets.

Because shorter Holstein cows need less living area, barn building and maintenance costs are lower. Changing the proportions of stalls, feeding spaces, and milking parlors may help maximize resource use and decrease overhead costs. More miniature cows are also more straightforward to handle in restricted quarters, reducing stress and damage and lowering costs associated with cow welfare standards.

A herd of the appropriate height might help reduce the expense of veterinary care. Joint tension and lameness cause fewer health problems for little cows than for large cows. This saves on veterinarian visits, treatments, and drugs, allowing the herd to stay healthy and productive without incurring significant healthcare costs.

The Importance of Balancing Height with Overall Conformation in Holstein Breeding

Holstein cows, known for their high milk yield, must meet rigorous confirmation standards to function well. One of the most important of these regulations is staying under 60 inches in height. This height increases the physical sustainability required for effective dairy operations and improves manageability inside barn structures. Reaching this height while retaining other essential characteristics such as udder quality, body capacity, and limb form requires effort.

Begin with bulls from lines that produce well-proportioned progeny; the sires listed below excel in high production while having relatively low stature. This genetic selection may significantly improve your chances of reaching your optimal height. Examining the maternal line may also assist in determining if female relatives have solid features and are within the ideal height range.

The Financial Upside: Why Shorter Holstein Cows are a Smart Investment for Small Dairy Farms

The economic implications of maintaining an optimal cow height are substantial, particularly for small dairy farm owners who must keep a keen eye on operational costs. Holsteins that do not exceed 60 inches can significantly reduce expenditures in several key areas, most notably feed, veterinary care, and housing requirements.

Firstly, the feed cost savings are non-trivial. A smaller cow generally requires less feed due to lower maintenance energy needs. For instance, a standard Holstein cow, averaging around 1,500 pounds, might consume approximately 50 pounds of feed daily, costing around $5 at a rate of $0.10 per pound. On the other hand, a Holstein that is bred to be no more than 60 inches tall might weigh closer to 1,200 pounds and consume around 40 pounds of feed daily, costing $4. This $1 daily savings can accumulate quickly over a year:

Standard Holstein: $5/day x 365 days = $1,825/year
Under 60 inches: $4/day x 365 days = $1,460/year
Annual Savings per Cow: $365

When maintaining even a modest herd of 50 cows, the annual feed savings alone can total $18,250.

Moreover, shorter cows tend to have fewer health issues and require less intensive veterinary care. Taller cows often experience more stress on their joints and greater susceptibility to certain infections, translating to higher veterinary costs. For illustrative purposes, suppose the average annual veterinary expense for a standard-sized Holstein is around $300, whereas for a shorter cow, it might be approximately $250. With 50 cows, this can lead to significant savings:

Standard Holstein: $300/year x 50 cows = $15,000/year
Under 60 inches: $250/year x 50 cows = $12,500/year
Annual Veterinary Savings: $2,500

Housing costs also benefit from smaller cows. Smaller animals require less space, leading to savings in building materials and maintenance expenses for barns and housing facilities. If the cost per housing unit for a standard cow is around $1,000 per year (including maintenance, bedding, etc.), whereas for a smaller cow, it might be $800, the annual savings can be computed as follows:

Standard Holstein: $1,000/year x 50 cows = $50,000/year
Under 60 inches: $800/year x 50 cows = $40,000/year
Annual Housing Savings: $10,000

By optimizing cow height and integrating these savings across feed, veterinary care, and housing, a small dairy farm with 50 cows could potentially save as much as $30,750 annually. These savings underscore the economic importance of strategic breeding for optimal cow height.

Monitoring and Managing Holstein Height for Optimal Conformation

Small dairy producers who value conformity must be able to manage the height of their Holstein cows efficiently. These valuable approaches might assist you in keeping your herd within the appropriate height range.

Accurate record-keeping: Accurate record-keeping is fundamental to effective herd management. Keep accurate records of each cow’s height measurements from birth and at crucial development stages. Frequent updates to this data will assist in identifying patterns and providing a foundation for educated choices.
Use Genomic Testing: Genomic testing may provide crucial information on potential offspring height. Testing for specific height markers allows you to make more educated breeding decisions. Businesses that provide such testing may examine DNA samples to predict future growth, allowing you to limit height proactively.
Choose Bulls Carefully: When breeding, it is critical to choose the correct bulls. Examine the genetic histories of possible bulls and choose those with a track record of generating progeny in the desired range. Bloodlines with firm genetic profiles, such as Hanoverhill Starbuck and Carlin-M Ivanhoe Bell, may help to maintain adequate height. Examine pedigree data and, ideally, interact with bulls whose offspring regularly demonstrate balanced development patterns. Choosing the right bull for breeding is quite important. Examine the genetic histories of potential bulls and choose those with a history of producing target height range offspring.
Customize Feed and Nutrition Plans: A healthy diet based on growth requirements may influence overall development, including height. Work with a livestock nutritionist to create a feeding plan that promotes regulated development while eliminating unwanted height increases caused by poor nutritional choices.

Combining these strategies allows dairy farm owners to maintain appropriate cow height, boosting overall farm efficiency and herd well-being. Proactive cow height monitoring and management highlight the importance of conformation in optimal dairy production.

The Bottom Line

Keeping Holstein cows at no greater than 60 inches has shown beneficial for several dairy farm management and production elements. The advantages include increased animal welfare, cost-effectiveness, and more efficient use of agricultural resources. By stressing height and overall conformation features, dairy producers may build a herd that thrives and contributes considerably to the farm’s prosperity. We advise dairy producers to carefully assess their existing breeding procedures and consider the benefits of raising Holstein cows of the appropriate height. This strategy may result in more sustainable and productive agricultural operations.

Rethinking Dairy Breeding: The Shift from Linear Selection to Genetic Indexes

Tuesday, July 23rd, 2024

Explore how transitioning from linear selection to genetic indexes can transform your dairy breeding approach. Are you prepared to maximize your herd’s capabilities?

For decades, dairy breeders have relied heavily on linear selection, prioritizing traits such as “taller,” “stronger,” and “wider.” While linear selection provided a straightforward blueprint, modern dairy operations showcase shortcomings. The key to success lies in accurate information. As genetic herd audits and sophisticated indexes become commonplace, the emphasis shifts toward traits like health, fertility, and lifetime productivity. The industry has been conditioned to believe that bulls with negative linear traits would sire inferior progeny. However, this concept is becoming increasingly outdated. Understanding the limitations of linear selection is essential as the industry evolves. This isn’t just theoretical—it’s about providing dairy breeders with the tools they need to thrive in an ever-changing agricultural landscape.

Accurate Information: The Cornerstone of Modern Dairy Management

Accurate information is not just important; it’s paramount in dairy management. It’s the bedrock for productive and profitable decisions. As the dairy industry evolves, the reliance on precise data becomes even more critical. Outdated methods and obsolete data can significantly misguide breeding choices, resulting in unfavorable outcomes. The role of accurate information in dairy management cannot be overstated, as it underlines the importance of data-driven decisions and the potential risks of relying on outdated methods.

For example, continuing to use linear selection as the sole criterion despite its directional simplicity can lead to the accidental selection of traits that do not align with contemporary herd needs. When the industry previously emphasized parameters like height and strength, it inadvertently cultivated cows with extreme stature, resulting in too tall and frail animals for optimal health and productivity. Such misguided selection pressures are evident in traits like rear teat placement, which suffered due to linear selection focused on front teat placement.

In contrast, indexes offer a more holistic approach, integrating multiple traits and their relative importance tailored to specific herd environments. They enable producers to weigh diverse factors such as health, fertility, and lifespan, resulting in more accurate breeding decisions that align with the desired outcomes. By employing up-to-date and comprehensive genetic audits, dairy managers can avoid the pitfalls of outdated methodologies, ensuring that their decisions are grounded in the most current and relevant information available.

Ultimately, the shift from traditional linear selection to more nuanced approaches underscores the critical role of accurate information. It empowers dairy producers to navigate the complexities of modern herd management effectively, allowing them to cultivate genetically superior cows that meet the industry’s evolving demands.

Enter the Genetic Index: A Holistic Approach to Herd Management

Enter the genetic index—a tool that presents a more stable and comprehensive selection method than the often rigid linear selection. Genetic indexes aggregate various trait data into a weighted value that better represents an animal’s overall genetic potential. This method effectively transcends the restrictive and sometimes misleading binary of linear selection.

Unlike the linear approach that prioritizes specific traits in isolation, genetic indexes consider a spectrum of factors influencing health, fertility, and productivity. For instance, an index can balance the importance of traits such as mastitis resistance, milk yield, and udder conformation, providing a holistic view of an animal’s genetic worth. This balance ensures that no single trait is disproportionately emphasized to the detriment of overall functionality and longevity.

Moreover, genetic indexes introduce flexibility into breeding decisions, allowing dairy producers to tailor selection criteria based on their herd’s unique challenges and goals. Genetic indexes support more precise and effective selection strategies by weighting traits according to their relevance to a dairy operation’s specific environmental and management conditions. This not only optimizes the genetic development of the herd but also enhances the adaptability and resilience of the cattle population, providing a sense of reassurance and security in the face of changing conditions.

The Limitations of Linear Selection in Modern Dairy Breeding

Linear selection, by its very nature, is limited in scope due to its two-dimensional approach. This method tends to focus on individual traits in isolation, often ignoring the broader genetic interconnections and environmental factors that also play crucial roles in a cow’s productivity and overall health. By simplifying selection to terms like “taller” or “stronger,” breeders are led to prioritize specific physical characteristics without fully understanding their implications on other vital aspects such as fertility, longevity, and disease resistance.

Moreover, the reliance on isolated traits can lead to unintended consequences. For instance, selecting taller cows might inadvertently result in too frail animals, as the emphasis on height could overshadow the need for robust body structure. Similarly, the traditional approach of choosing bulls based on their linear traits might not account for the holistic needs of a modern dairy operation. It creates a scenario where the ideal cow for a particular environment is overlooked instead of one that fits a historical and now possibly outdated, linear profile.

Such an approach also fails to account for the dynamic nature of genetic progress. While linear selection might have worked under past environmental and market conditions, today’s dairy industry demands a more nuanced and comprehensive strategy. The ever-changing landscapes of health challenges, market preferences, and production environments necessitate a departure from the rigid, two-dimensional framework that linear selection represents.

The Evolution of Linear Selection: A Historical Perspective on Dairy Breeding

Understanding the evolution of linear selection in dairy breeding requires a historical lens through which we observe genetic trends and the shifting paradigms that have guided these trends. Over the past five decades, one prominent example is the selection for stature in U.S. Holsteins. Initially intended to produce taller cows, this linear selection was driven by the belief that larger animals would be more productive. From a base stature of 52 inches (132 centimeters) in the early 1970s, selective breeding practices have seen this trait rise by an average of 5.5 inches (14 centimeters). Today, the daughters of Holstein bulls with an STA of 0.00 for stature typically measure around 57.5 inches (160 centimeters).

However, as cows grew taller, unintended consequences emerged. Larger cows often experienced greater strain on their skeletal structures and faced increased incidences of lameness. Additionally, the shift toward extreme measurements, such as overly tall and frail cows, suggested that these changes might have overshot the ideal productive physique for dairy cows. The selection pressure inadvertently guided breeding decisions to focus on traits that, although historically perceived as desirable, began to conflict with emerging dairy production environments and herd health priorities.

These changes also had profound implications for other linear traits. For instance, as the focus shifted towards enhancing front teat placement, little attention was paid to rear teat placement, creating new challenges for dairy breeders. This historical perspective underscores the adaptability required in breeding practices. It suggests the necessity for a more balanced, holistic approach moving forward—a lesson clearly illustrated by the evolution of indices in modern selective breeding. The need for a more balanced, holistic approach in breeding practices is a crucial takeaway from past experiences, highlighting the industry’s adaptability.

Refining Genetic Evaluations: Understanding Standard Transmitting Abilities (STAs)

Standard Transmitting Abilities (STAs) is a refined way of expressing genetic evaluations for linear-type traits, offering a clearer and standardized metric for comparison. Calculating STAs involves transforming Predicted Transmitting Abilities (PTAs) into a common scale, making disparate traits easily comparable.

To calculate STAs, PTAs are first derived using advanced genetic models that consider various data points, including parent averages, progeny records, and contemporary group adjustments. These PTAs are then converted into STAs, standardized values representing animals’ genetic merit relative to a modern population base. The practical range of STAs spans from -3.0 to +3.0, with most bulls and cows falling within -2.0 to +2.0, ensuring a bell-curve distribution that simplifies interpretation.

Understanding STAs involves recognizing their role in evaluating linear-type traits with precision. For instance, an STA of 0.00 indicates an animal is average for the trait in the current population, while positive or negative values denote deviations above or below this average. This standardization allows producers to make informed breeding decisions by identifying superior genetics that align with specific breeding goals. By focusing on STAs, breeders can strategically select traits that enhance overall herd performance, ensuring that each generation successfully builds on the genetic progress of the previous one.

The Case of Stature: Unintended Consequences of Generational Linear Selection

The case of stature vividly illustrates the unintended consequences of linear selection over generations. Initially, breeders prioritized increasing the height of cows, associating taller stature with improved dairy production and greater robustness. However, this singular focus on height overlooked other crucial traits, including udder health and reproductive efficiency. As a result, while stature improved dramatically—rising by an average of 5.5 inches (14 centimeters) over the past five decades—dairy cows’ overall performance and longevity faced unforeseen challenges.

Consider the comparative example of Holstein cows. A bull with a Standard Transmitting Ability (STA) of 0.00 today would sire daughters averaging 57.5 inches (160 centimeters) in height—significantly taller than the 52-inch (132 centimeters) cows at the same STA level five decades ago. If breeders were to select bulls with a -3.00 STA for stature now, their daughters would still be 56.5 inches (143.5 centimeters) tall, which reveals the lasting impact of generational selection for height.

This relentless push for increased height did not occur in isolation. Physical attributes and health traits were often compromised to achieve a taller stature. Breeders globally started observing cows “too tall, too frail,” with structural deficiencies such as “short teats and rear teats being too close together.” These physical alterations posed significant management issues—cows with excessively tall stature frequently experienced increased stress on their skeletal systems and a higher propensity for lameness, negatively affecting their productivity and well-being.

Consequently, this relentless focus on linear selection for stature resulted in a breed that, while visually impressive, often struggled with underlying health and productivity challenges. This is a stark reminder that breeding programs must consider a holistic approach, acknowledging the multifaceted nature of genetic traits, to develop a well-rounded, high-performing herd suited for sustainable dairy farming.

The Overlooked Consequence: Rear Teat Placement and the Pitfalls of Linear Selection

The issue of rear teat placement offers a stark example of the unintended consequences that can arise from linear selection focused predominantly on front teat traits. Historically, the selection protocols that emphasized front teat placement, aiming for a “Plus” positioning, did not account for the correlated effects on the rear teats. As a result, we observed rear teats becoming too close together, an outcome that was neither anticipated nor desired. This misalignment can compromise udder health and milking efficiency, leading to increased mastitis and difficulties in machine milking. The focus on improving one set of traits—front teat placement—without considering the holistic impact on the overall udder structure underscores the pitfalls of a unidimensional approach to selection. By shifting towards more integrated evaluation methods, like indexes that incorporate multiple relevant traits, we can better address such complex genetic interrelations and enhance the overall functionality and health of the herd.

Redefining Priorities: From Linear Extremes to Balanced Herd Management

Linear selection has driven the dairy industry’s breeding decisions to a point where the traits we once sought to enhance have become liabilities. The focus on extremes—stature, strength, or teat placement—has created cows that are often too tall, frail, or have inefficient udder configurations. These unintended consequences affect the cows’ health and productivity and create additional management challenges, thereby impacting the overall efficiency of dairy operations.

A paradigm shift is necessary, moving from the myopic focus on linear traits to a more balanced and holistic breeding approach. The comprehensive indexes available today offer a more nuanced and multi-dimensional framework. Unlike linear selection, which tends to prioritize singular traits often to the detriment of others, indexes provide a weighted consideration of a range of characteristics that directly impact a cow’s longevity, health, and productivity. This method aligns with the practical realities of modern dairy farming and supports the creation of robust, well-rounded cows capable of thriving in diverse environments.

Relying solely on linear selection is an outdated practice in a time of paramount precision and efficiency. The industry’s future is leveraging complex genetic evaluations and indexes incorporating various health, productivity, and fertility traits. Such a move will ensure the creation of an optimal herd that meets both contemporary market demands and the rigorous demands of modern dairy farming.

Embracing Indexes: A Paradigm Shift from Linear Composites

Indexes represent a modern and holistic approach to genetic selection that contrasts significantly with traditional composites. While composites aggregate linear values into a single selection metric, they often fail to account for the nuances needed for specific herd environments. On the other hand, Indexes maintain each trait’s integrity by assigning a weighted value to it based on its relevance to the optimal cow profile for a given environment. This method ensures that traits essential to the animal’s health, productivity, and longevity are prioritized according to their real-world importance. For instance, if mastitis is prevalent in a particular region, the index would appropriately weigh this health trait to screen for less-prone genetics. By doing so, indexes facilitate a targeted and balanced breeding strategy, allowing producers to cultivate not only productive but also well-suited cows to thrive in their specific operational conditions.

Indexes: A Multifaceted Approach Beyond Linear Selection

Indexes offer a multifaceted approach to dairy breeding, transcending the limitations of linear selection. One of the primary advantages of using indexes is their capacity to integrate a wide array of traits, including those related to health and overall performance. Indexes provide a more comprehensive assessment of genetic potential by weighting each trait according to its relevance and impact on the ideal cow for a specific environment.

This holistic approach ensures that essential health traits, such as mastitis resistance and fertility, are factored into breeding decisions. By incorporating these traits, indexes help identify cows that are not only high performers but also robust and resilient, enhancing their longevity within the herd. The ability to screen for low-heritability traits, which might otherwise be overlooked in linear selection, further refines the selection process, aiding in avoiding genetic extremes that could compromise herd health and productivity.

Moreover, indexes facilitate more accurate and adaptable breeding strategies that align with a given dairy operation’s specific challenges and goals. Whether the focus is on increasing milk yield, improving udder health, or selecting moderate frame sizes, the weighted values in an index can be tailored to match the unique conditions of the herd’s environment.

In essence, indexes empower dairy producers to make informed decisions that balance productivity with sustainability, ultimately leading to the development of cows that excel in performance and longevity. This strategic approach not only optimizes genetic gains but also promotes the welfare and durability of the herd, ensuring a more stable and prosperous future for dairy operations.

Navigating Genetic Index Selection: Tailoring Traits to Your Herd’s Needs

Choosing the right genetic index for your dairy cows involves understanding and prioritizing the traits that align with your herd’s needs and environmental conditions. Here are essential steps to guide you:

Identify Herd Goals: Define what you want to achieve with your herd. Are you focusing on milk production, fertility, health, or longevity? Your goals will determine the traits you must prioritize in your genetic index.
Analyze Current Herd Performance: Use data from sources like the DHI-202 Herd Summary Report to evaluate your herd’s strengths and weaknesses. This helps identify traits that require improvement.
Consider Environmental Factors: Consider the environmental conditions your cows face. Weather, feed quality, and herd health can influence which traits are most beneficial to focus on for optimal performance.
Review Trait Heritability and Economic Impact: Not all traits are equally heritable, and some have a more significant economic impact than others. To maximize genetic progress, focus on traits with higher heritability and substantial financial benefits.
Weight Traits Appropriately: Use the relative importance of each trait in your selected index. Traits that significantly impact your herd’s productivity and profitability should have higher weightings in the index.
Utilize Comprehensive Genetic Audits: Engage in periodic genetic audits to track the progress and effectiveness of your breeding decisions. This ensures your genetic selection continues to align with your evolving herd goals.
Consult Industry Experts: Work with genetic consultants or utilize industry tools and resources to refine your genetic indexes. Expert advice can provide valuable insights and help tailor indexes to your herd’s unique needs.

By thoughtfully choosing and applying the proper genetic indexes, dairy producers can enhance the overall genetic quality of their herd, achieving a balance between high productivity and sustainable herd health.

The Bottom Line

As we navigate dairy breeding, shifting from linear selection to genetic indexes is revolutionary. Indexes align breeding strategies with modern needs, ensuring cows are robust, fertile, and productive over their lifetimes. While linear selection once worked, it shows limitations like increased stature and flawed teat placement. In contrast, genetic indexes consider health, fertility, and productivity dynamically. Indexes breed cows that are better suited to their roles by weighting traits for specific environments.

Adopting genetic indexes has profound implications. Herds become more resilient, operations more sustainable, and the genetic health of dairy populations improves. This approach reduces breeding extremes, fostering balanced herd management that adapts to varying challenges and environments. Embracing genetic indexes addresses past shortcomings and shapes the future of dairy breeding.

Key Takeaways:

Shifting from linear selection to genetic indexes can provide more stability and adaptability in herd management.

Consider a dairy farm where cows get pregnant shortly after calving with minimum manipulations. This is not a pipe dream; deliberate fertility selection may make it a reality. High fertility in dairy farming leads to shorter calving intervals, improved milk production cycles, and increased profitability.

Rapid pregnancy following calving is critical for a robust herd and sustainable operations. Pregnancy consists of various stages: the uterus returns to normal after birth, estrous cycles resume, and estrus is recognized. Sperm is subsequently placed and capacitated, ovulation and fertilization occur, and the corpus luteum generates progesterone to keep the pregnancy going. Each phase is heritable and necessary for a successful pregnancy after insemination.

Prioritizing fertility benefits dairy producers by reducing inseminations, lowering veterinary expenses, and increasing herd output. The potential for profitability via genetic selection for features that ensure fast pregnancy after insemination has the potential to change dairy production. This realistic method may improve dairy operations, offering farmers hope and motivation.

Overcoming Fertility Challenges in Modern Dairy Farming: A Path to Sustainability and Profitability

Modern dairy producers have substantial reproductive issues critical for profitability and sustainability. Reducing the number of inseminations required for pregnancy is vital since each additional effort increases expenses and extends the calving interval, affecting milk output and herd efficiency. ‘Days open,’ or the time from calving to successful insemination is essential in fertility control. Quick pregnancy establishment after calving is critical; delays in uterine involution and estrous cycle re-establishment might impair fertility.

Accurate estrus identification is crucial for maximizing breeding chances and reducing days open. Reproductive management approaches vary in efficacy and depend on cow circumstances and farm management practices. Some systems utilize natural estrus detection, while others use hormonal therapies such as PGF2α and GnRH with timed AI.

Genetics has a significant impact on fertility. While selection tries to minimize the number of days open, the diversity of dairy systems implies that favorable features in one system may not transfer well into another. Understanding reproductive genetics and their interaction with various management approaches is essential for making educated breeding choices. This information gives dairy producers greater confidence and control over their operations.

Achieving high fertility in dairy cows requires careful reproductive management, precise estrus detection, and a thorough grasp of genetics. This knowledge includes identifying heritable features and considering their interactions and possible trade-offs when making breeding choices. Addressing these factors may improve herd reproductive performance, resulting in more sustainable and profitable farming.

The Journey from Uterine Involution to Progesterone Production: A Symphony of Reproductive Success

The first phase following calving is uterine involution, which restores the uterus to its pre-pregnancy condition and lays the groundwork for future reproductive cycles. After involution, the cow’s reproductive system returns to regular menstrual cycles, preparing for future pregnancies.

The next step involves detecting and expressing estrus. Estrus, sometimes known as ‘heat,’ occurs when a cow is sexually receptive and pregnant. Properly detecting this phase is critical for effective insemination. During estrus, sperm enter the cow’s reproductive canal and undergo capacitation. This process allows the sperm to penetrate and fertilize the egg.

Following capacitation, ovulation occurs when an egg from the ovary enters the oviduct and meets the capacitated sperm. Fertilization is the process of combining sperm and egg to form an embryo. After fertilization, the corpus luteum develops on the ovary and produces progesterone, essential for pregnancy and embryonic development.

Each process, from uterine involution to progesterone production, is critical for obtaining and maintaining pregnancy in dairy cows. Understanding and improving biological processes may boost fertility rates, increasing production and profitability in dairy farming.

Delving into the Heritability of Fertility Traits: From Uterine Involution to Embryo Development

Exploring the heritability of fertility characteristics requires understanding how each event in the reproductive sequence contributes to the overall fertility phenotype in dairy cows. This process, which begins with uterine involution, characterizes the early postpartum period and is crucial for restoring normal reproductive function. Genetic variables impacting the rate and effectiveness of uterine involution may be heritable, possibly decreasing the time between calving and the following successful pregnancy.

Another critical event is the restoration of estrous cycles. The capacity to resume regular estrous cycles promptly significantly impacts conception rates. Genetic variation affecting the timing and regularity of these cycles is most certainly heritable, influencing how easily and quickly cows may be inseminated again.

The next step is estrus expression and detection. Cows with apparent indications of estrus are more likely to be effectively inseminated. Traits related to estrus expression, such as the strength and length of behavioral indicators, may be handed down across generations, influencing fertility.

Sperm deposition and capacitation in the reproductive tract are equally important. Efficient sperm capacitation for conception requires both male and female genetic contributions. Genes that affect the uterine environment and sperm cell function may increase the chances of successful sperm capacitation and subsequent conception.

Ovulation, an important occurrence, is governed by hormone cycles and is genetically controlled. The time and predictability of ovulation may be chosen, resulting in more effective inseminations. Following ovulation, the creation and function of the corpus luteum (CL), which generates progesterone, is crucial for pregnancy maintenance. Heritable features that promote robust CL development and sufficient progesterone production are critical for establishing and maintaining pregnancy.

Beyond these phases, the oviduct’s involvement in promoting embryonic cleavage and the uterus’ formation of a receptive environment is potentially heritable. Genetic predispositions that favor specific settings may increase embryo survival and development, eventually enhancing fertility rates.

The phenotypic manifestation of fertility in dairy cows comprises many heritable variables, each influencing a particular event in the reproductive process. Selection for these qualities may increase total fertility, making genetic knowledge and selection an essential component of sustainable and lucrative dairy production.

Optimizing “Days Open”: The Pinnacle of Genetic Selection for Enhanced Dairy Cow Fertility

Genetic selection for fertility in dairy cows primarily focuses on minimizing the number of days between calving and pregnancy, sometimes known as “days open.” This statistic is important because it captures the overall influence of several specific fertility components. Each stage of the reproductive process—from uterine involution, re-establishment of estrous cycles, and successful ovulation to efficient sperm capacitation, fertilization, and the creation of a functioning corpus luteum—is critical in determining whether a cow gets pregnant following insemination. By concentrating on lowering the number of days open, dairy producers and geneticists select cows more efficiently, restarting reproductive cycles and effectively conceiving after calving. This complete method guarantees that selection pressures are equally dispersed, resulting in improved reproductive features for sustainable and prosperous dairy production.

Customizing Reproductive Strategies: Navigating Between Minimal Intervention and Intensive Management Systems

In dairy farming, reproductive management is vital in determining fertility and total herd output. Different approaches improve breeding efficiency, each with unique benefits and uses. Minimal intervention approaches, for example, depend heavily on recognizing natural estrus. Cows in such systems are watched for indicators of estrus, such as mounting behavior or increased activity, and insemination occurs once estrus is recognized. This strategy may improve breeding accuracy by inseminating cows when they are most fertile, perhaps lowering the number of inseminations necessary for pregnancy. However, detecting modest estrus symptoms requires tremendous effort and experience.

On the other side, more extensive reproductive management approaches include hormone therapies and scheduled artificial insemination (AI). To synchronize a group of cows’ reproductive cycles, procedures may consist of giving PGF2α to induce luteolysis and GnRH to trigger ovulation. This synchronization enables timed AI, where insemination happens at a particular time regardless of obvious estrus signals. This strategy has the benefit of being consistent and predictable, which might lead to increased conception rates and more efficient herd management. Nonetheless, this strategy requires exact timing, extra hormone expenses, and strict protocol adherence.

The dairy operation’s unique demands and capacity determine the decision between minimum intervention and extensive reproductive management methods. Minimal intervention techniques may be more practical for smaller herds with enough manpower. At the same time, larger operations may benefit from the efficiency and consistency of timed AI protocols. Understanding each system’s strengths and limitations is critical for improving reproductive results and unlocking the genetic potential of contemporary dairy cows.

Different Management Systems, Different Genetic Pressures: Strategizing ‘Days Open’ for Optimal Fertility

Different reproductive management systems provide different stresses to the specific fertility components, impacting the selection process for days. Cows are inseminated mainly after estrus is identified in minimum intervention systems, stressing the cow’s inherent ability to have regular cycles and evident symptoms of estrus. Days open to become a composite metric representing several distinct fertility qualities, including estrus detection, sperm capacitation, and ovulation time. Genetic selection in these systems promotes features associated with high natural reproductive success and low human intervention.

In contrast, rigorous management methods that include hormonal therapies like PGF2α and GnRH, followed by scheduled artificial insemination (AI), shift the relevance of reproductive features. In this context, characteristics such as responsiveness to hormone therapies and scheduled AI cycle success rates are relevant. Days open remain crucial, but the various fertility components contributing to it may be weighted differently. For example, the precision and timing of ovulation caused by hormonal treatments may become more important than natural estrus-detecting skills.

Such variances demand a detailed knowledge of fertility genetics to choose cows that perform consistently well across various reproductive management measures. Adaptive genetic selection may retain fertility features across farm operations, leading to better reproductive success and profitability for dairy herds.

Genetic Insights: Paving the Way for Uniform Fertility Performance in Diverse Dairy Management

Obtaining consistent fertility performance across diverse reproductive management systems will demand a more in-depth knowledge of the genetics of each fertility component. This involves more than simply examining surface-level features; it also necessitates looking into the genetic markers and pathways that regulate each stage of the reproduction process. By identifying and comprehending these genetic characteristics, dairy producers may choose cows that perform well under minimum intervention systems while excelling under more extensive, hormone-based management schemes. Such insights might lead to the establishment of customized breeding plans adapted to the individual needs of various dairy farming operations, improving the herd’s sustainability and profitability. Advanced genomic techniques and technology will be critical in this effort, providing unparalleled accuracy in selecting and breeding tactics. This integrated strategy may improve the reproductive efficiency of dairy cows, leading to a more resilient and productive dairy sector.

Key Takeaways:

The primary definition of fertility in dairy systems is the establishment of pregnancy post-insemination.
Highly fertile cows establish pregnancy sooner after calving, requiring fewer inseminations.
Fertility involves several sequential events: uterine involution, re-establishment of estrous cycles, expression and detection of estrus, sperm capacitation, ovulation, fertilization, and corpus luteum progesterone production.

Organic Production Systems: Streamlining Breeding Goals for Enhanced Sustainability

Wednesday, May 1st, 2024

Welcome to the wondrous world of organic agriculture, where the compassionate emphasis on sustainability and natural processes carves out a unique approach to livestock breeding. A world, where the rhythm of life aligns with the rhythm of nature, giving birth to a symphony of sustainable production. Organic dairy farming, in particular, stands on the edge of this realm, facing a dualistic challenge of its own.

These brave farmers strive to meet ambitious productivity and economic goals, all while adhering to the rigorous principles of organic agriculture. This balancing act calls for not only dexterity but also a deep understanding of the breeding processes involved. With their eyes locked onto the pursuit of higher yield and the maintenance of economic viability, they still have to ensure the ethical treatment of the involved livestock is never compromised.

Stay with us as we delve deeper into the mechanics of organic dairy farming, to chart out breeding strategies that stay true to organic ideals and pave the way to sustainable agriculture. This is not just a challenge, but also an opportunity to create a production system where nature and agriculture exist in harmony, contributing to the overall health of our planet.

Understanding Organic Dairy Farming

As a steward of Mother Nature’s bounty, you play a pivotal role in the organic dairy farming industry, operationalized by the key principles of curtailing synthetic inputs like chemicals and antibiotics, maximizing animal welfare, and promoting environmental health. Your farming system relies heavily on natural processes – think pastoral grazing, organic feed, and holistic health management practices.

Your role doesn’t just stop at maintenance, it also extends to breeding strategies. Ever considered your breeding strategy? It’s not merely about compliance with core standards – it’s also about building up a robust lineage of cattle that can thrive, really flourish, under organic conditions. This translates to cattle that is resourceful by nature and that can leverage natural processes for growth and health, fitting seamlessly into the organic narrative of your dairy farm.

Streamlining Breeding Goals

To align with the overarching goals of organic production, breeding strategies need to be carefully designed. Here are the key aspects to consider when streamlining breeding goals for enhanced sustainability in organic dairy systems:

Robustness and Health: Organic dairy cows need to be particularly resilient. Breeding for robustness involves selecting traits that enhance the cow’s natural ability to resist diseases and adapt to various environmental stresses without reliance on antibiotics or other synthetic treatments. This includes traits like hoof health, udder health, and overall immune system strength.
Longevity and Fertility: Longevity is a critical trait in organic dairy farming because it reduces the need for frequent replacements and enhances the overall sustainability of the herd. Similarly, high fertility is essential to maintain productive herd dynamics. Selecting for these traits can lead to fewer interventions required in the reproductive process, aligning with organic standards.
Efficiency of Resource Use: Organic cows must be efficient converters of a forage-based diet to milk. This not only improves the farm’s economic sustainability but also reduces environmental impacts. Breeding goals should therefore include feed efficiency and the ability to maintain production levels on a predominantly grass-based diet.
Behavioral Traits: In organic systems, where cows often have more freedom of movement and social interaction, behavioral traits become significant. Traits such as temperament and social hierarchy integration can impact the welfare of the entire herd. Selecting animals that exhibit calm and sociable behaviors can lead to smoother herd management.
Milk Quality Over Quantity: While conventional systems often prioritize high milk yield, organic systems may benefit more from optimizing milk quality. Traits that enhance the nutritional content of milk, such as increased levels of omega-3 fatty acids or better protein profiles, are highly valuable. This approach not only meets the consumer demand for high-quality organic products but also supports sustainable production practices.

Implementing Breeding Strategies

Implementing these breeding goals in organic dairy production requires a multifaceted approach:

Genetic Selection Tools: Utilizing advanced genetic tools and technologies, such as genomic selection, can help identify and propagate desirable traits more efficiently.
Crossbreeding: Introducing genetics from traditionally hardier breeds can improve the robustness and adaptability of the herd.
Data-Driven Decisions: Maintaining detailed records on animal health, production, and behavior aids in making informed breeding decisions that align with organic principles.

Challenges and Opportunities

While charting the course for breeding goals in organic dairy production, you’ll encounter hurdles. Chief among these are the sluggish rate of genetic advancement and the complicated task of selecting ideal traits. Nevertheless, don’t let these challenges deter you. They’re surmountable, and the rewards are immense. Despite these challenges, there are noteworthy chances to boost sustainability.

The key to navigating this complex matrix of factors lies in concentrating on the health and efficiency of animals. This focus enables organic producers to create a production system that ticks all the boxes. It’s not just about the economic standpoint; a successful organic dairy production system also passes the test on ethical and environmental grounds. It’s all part of a delicate and intricate balance that needs to be achieved.

The approach suggested here is in line with the stance, “Animal husbandry needs to be sustainable and biologically sensible,” that emerged in 2011 and gained popularity in 2012. The call is for a model, which aligns with nature’s rhythm and respects all life within its sphere of operations.

But remember, this is just one part of the larger scheme of things. A knowledge gap regarding GxE interactions, particularly in pig production in organic systems, came to light in 2013. This gap needs filling, and here lies a significant opportunity for research and development to enhance overall sustainability.

Aiming for locally-adapted and dual-purpose breeds in organic animal breeding, as per the 51-point principle defined in the Economic Values framework back in 2013, could be part of the answer. This approach not only promotes survivability and efficiency but also fosters resilience and adaptability. It’s an organic symphony where every note matters, each one contributing to the grandeur of sustainability.

The Bottom Line

As we envision a future where the appetite for organic dairy products steadily heightens, it’s apparent that the refining of breeding goals can provide the blueprint for stronger, more sustainable farming methods. Your commitment, as an organic dairy farmer, to diligently pursue interconnected and all-encompassing breeding practices can significantly amplify the sustainability score of your business, effectively lowering your carbon footprint. In doing so, not only are you bolstering resilience within your operations but also you’re actively contributing to a positive, healthy, and thriving global food system – a change that goes far beyond your barn. Make no mistake, your endeavors today are not just shaping your farm’s sustainability; they’re redefining sustainability for the entire dairy industry.

Can We Create Holstein Blood Lines to Feed The World?

Wednesday, July 17th, 2019

Are we missing out on an opportunity to exploit the genetic potential of the Holstein breed worldwide?

Opportunity Knocks

There is already robust global trade among countries involving semen from Holstein bulls and embryos from Holstein cows. This market is competitive and profitable for those that understand its needs and cultures.

Much of this market is in countries that have businesses, organizations and agencies that are members of Interbull https://interbull.org/index. These countries had an estimated 44.5 million milk cows in 2017, based on the UN’s Food and Agricultural Organization. This is a large market, but it leaves out nearly 85% of the world’s milk cows.

Fine Tuning Holsteins

Holstein cows can be found around the world, but when one digs a little deeper to see why there aren’t more, it seems likely that the breed is missing some traits, genes or characteristics that just don’t fit some parts of the world. Maybe there is a lack of heat tolerance or a lack of resistance to some diseases or parasites. Maybe it’s associated with a need in parts of the world for cattle to provide power for ploughing and hauling, but it leaves out nearly 85% of the world’s 290M milk cows.”

Or maybe it is a reluctance of Holstein breeders to break out of there shell of purity to create cattle that will serve much of the world more efficiently. This is no longer a dilemma in some other agricultural species like chickens and pigs because the breeders and breeding companies that serve these species have developed different lines to meet different needs within and among countries. We’ve seen the same thing with soybean breeders where different lines of soybeans have been developed for different latitudes and climatic regions of the world.

Four Cattle Climate Zones

Climate experts have looked at the globe and classified the types of climatic zones that exist worldwide. The experts say we have 5 zones, but only 4 of those are tolerable for cattle. The Polar Tundra may be tolerable someday, but not in the foreseeable future. That means that we have only four climate zones to serve worldwide. Four! That’s right: 4! We even have 3 of those zones in North America. Every continent has at least 3 of the 4 zones. That makes the problem of creating lines for different climate zones simpler.

The global map shows the zones and their locations. We’ve numbered these from 1 to 4 and put numbers in various areas to illustrate the zones within a single country or region. If one looks carefully at North America, South America, Africa, Asia or even Australia, you will see multiples of the four zones.

The Challenge Is Doable

Four lines of Holstein cows! That does not seem too challenging, particularly with the huge amount of global data that we already have and the number of countries around the world that are already engaged in Interbull and similar organizations.

So how do we get there?

First, most of our existing Holstein cows fit well in the Cold Zone (Zone 1). That represents lots of the Northern Hemisphere. We just need to continue focusing on improved health and fertility and enhance components for Line 1.

Zone 2 is temperate, and we’ve generally used housing and cooling technologies to allow Holsteins to do well in these areas. Worldwide there is a lot of temperate land base, and as we see warmer temperatures in the summer in many regions, such as we’ve seen in Europe over the last two years, it may be time to put some heat-tolerant genes in Holsteins in these regions. Some breeders and universities have already done that, but we need to make it easier and simpler to do some crossbreeding to get desirable traits without taking too many generations to be called a “Holstein line”. Today’s genomic tools will allow us to do that more efficiently and effectively, potentially by screening embryos before they are transferred so that we get the most desirable of genes quickly.

The Dry Desert (Zone 3) is filled with Holstein cows today, but there are some traits that could be enhanced for cows in these zones. Solar stress may be their greatest challenge and when one adds that to the internal heat generated by rumen fermentation, it becomes a challenge for the cow to dissipate heat, even in a climate with low humidity. Traits like increased sweat glands, changes in color pattern and even changes in digestion efficiency may be important in these areas. Zone 3 also comprises countries in Africa that have millions of cows. Ethiopia, Sudan, South Sudan and Tanzania collectively have 34 million milk cows! That is a huge marketplace. We need to know a lot more about what traits they need to meet their needs.

The Tropical Zone (Zone 4) is characterized by high humidity and high temperatures year-round. There are very successful dairies in these regions where Holsteins have been crossed with native breeds. They can grow a lot of forage, but often it has lower digestibility. The traits needed in this line are probably already reflected in some of the local crossbreds that one sees. Upgrading those a bit may be a quick way to create this line

Four Holstein Lines – Advantages / Disadvantages

What additional advantages would be derived from creating four Holstein lines?

We could greatly enhance the ability of various countries to provide high-quality food for their residents while adhering to some of their traditional practices.
We would introduce greater genetic diversity into the breed and potentially prevent “genetic crashes” that could occur because of limited genome sequences in some DNA segments on some chromosome in the breed.
We could help our industry be prepared in advance as our climates change and our own farms transition from one zone to another as future generations take over the farm.
We could help breeders develop some specialized lines for the non-traditional global market – a market which will grow a lot in the next few decades.
Advances in using genomics to evaluate crossbreds will be a big advantage in such an undertaking.

What are the disadvantages?

Holstein breeders might begin to look more like hog, chicken and soybean breeders. Is that good or bad? It is probably a bit like reality television. People may not like the concept, but they tune in!
The Holstein Associations may have to loosen their rules a bit. They have already discovered that there was a 10-20% error rate in sire or dam ID when genomics started being used broadly. Maybe 100% purity needs to be rethought. If you have an 80% chance of winning the lottery, maybe you would still buy a ticket.

Lines Must be Created Through Selection

Can we do this with gene editing? Nope! Most of the traits that are of interest to us are controlled by many, many genes. Gene editing can work well for one gene, but not for 10 or 20 or 30 that might control some trait of interest. We will need traditional breeding with high levels of genomics before mating and after birth of the calves to do this correctly.

Lines are different than line breeding! Linebreeding typically traces back to a bull or cow over multiple generations. Lines are developed by focusing on certain traits and environmental situations to meet the ultimate needs of the farmers and their customers.

Let’s Get Started

Do our Holstein breeders and organizations have the courage to jump into this pond and swim to the other side, not knowing what is beneath the surface? It is a bit like July 20, 1969. “Tranquility base here, The Eagle has landed.” It was the vision of getting to the moon and back that drove this accomplishment. No one knew how to do it when they started. But they started!

Genomic Young Bulls: Accelerating Genetic Progress

Tuesday, October 3rd, 2017

To what degree have you embraced genomics? Perhaps the easiest way to measure this is by your usage of semen from genomic young bulls. Some breeders have adopted a policy to use only semen from genomic young bulls while others have maintained a more limited usage. Let’s take a closer look at some national trends, which demonstrate how genomic young bulls have significantly accelerated the rate of genetic progress in Canada.

Market Share

Based on insemination data for the first half of the year, the semen market share taken up by genomic young bulls hit the 70% mark in 2017, which compares to under 40% prior to the introduction of genomics in 2009 (Figure 1). Young sire market share spiked up quickly in 2010 as breeders wanted early access to elite sire blood lines that reached proven status in 2011. Thereafter, the adoption of genomic young sire usage has continually grown, year after year, to now reach 70%. Breaking this market share down further, one-third of it represents semen from genomic young bulls under two years of age while two-thirds is from bulls between two and four years of age.

Average Genetic Merit and Annual Gain

So why are breeders using more and more semen from genomic young bulls? The answer to this question is provided in Figure 2, which is based on young bulls marketed by A.I. companies with semen used in Canada. Genomic young bulls that had their semen released for use in Canada in 2016 have an average genetic merit of 3076 LPI (Figure 1) and $2226 Pro$. Figure 1 shows the trend in the average LPI for young bulls marketed in Canada since 2003 and defines three distinct time periods – before genomics (bulls with semen released before 2007), genomics introduction (bulls released between 2007 and 2010) and genomics adoption (bulls released since 2011).

Table 1 provides a summary of the average annual gain for LPI and Pro$ for the young bulls offered to Canadian producers during each of the three time periods. Prior to genomics, the average increase in the genetic merit of young bulls tested in Canada was 54 LPI points and $87 for Pro$ (even though it did not exist at that time). For young bulls with semen released between 2007 and 2010, for which some genomic information was made available, the average annual gain was 99 LPI points and $172 Pro$, which translates to almost double the annual gain being achieved before genomics (i.e.: 1.83 and 1.98 fold for LPI and Pro$ respectively). Since genomics has been fully adopted by A.I. organizations for young sire selection, which occurred in 2011, genomic young bulls offer an average increase of nearly 150 LPI points per year and over $250 Pro$ per year, which is approaching rates of annual gain that are three-fold those achieved prior to genomics. Since Pro$ is an economic index expressed in dollar units, this result means that daughters of the genomic young bulls offered in 2016 will average nearly $700 more profit per daughter over their lifetime compared to the average daughter of bulls with semen released in 2013, most of which are now progeny proven. This makes for a strong economic argument in favour of using high levels of genomic young bulls compared to progeny proven sires.

Summary

The popularity of genomic young sires continues to grow and reached the 70% mark based on inseminations during the first half of 2017. Although there is a growing trend towards the use of genomic young bulls aged two to four years, compared to those under two years of age, there is no indication that the overall use of genomic young bulls will plateau off in the near future. The significant trend in terms of semen market share is driven by the genetic superiority of the genomic young bulls being offered to Canadian producers year after year. High selection pressure being applied by A.I. organizations has translated to major increases in the genetic merit of young bulls marketed in Canada, averaging gains of 150 LPI points and $250 Pro$ each year.

Polled genetics – examine the pros and cons

Tuesday, May 30th, 2017

The polled gene in dairy cattle is dominant over the horned gene

Polled dairy cattle trace back as far as pedigree records have been kept. The polled gene in dairy cattle is dominant over the horned gene. Yet horned cattle are still much more prevalent in the global dairy population because few producers ever chose to select for polled cattle as part of their breeding program. This is because the real, economic paybacks of selecting for production, health and conformation traits has traditionally trumped the desire for polled genetics.

Genomic selection has allowed polled enthusiasts to focus on high ranking polled animals to propagate the polled population. However, producers stressing genetic improvement in other traits are also advancing their genetics at an equally rapid rate.

You can add polled as a criteria to your genetic plan, but must keep in mind the financial repercussions of that decision in terms of the pounds of milk and components you’ll give up, and the health and fertility you may need to sacrifice, just to avoid dehorning.

The more recent public awareness about dehorning cattle has made it another hot button topic in the industry. The naturally hornless cattle have gained popularity in recent years because of consumer opinion on the dehorning process, and the side effects they feel result from it. This perception has driven producers to create more naturally polled animals than ever in the past.

The pros of polled genetics

Despite the genetic and performance sacrifices made by selecting for polled animals, many producers do see the opportunity to incorporate polled genetics into their breeding program.

Avoid dehorning

You can save dollars, time, and labor, and also minimize stress on your calves by foregoing the need for dehorning. The average dehorning cost varies from one farm to the next based on the chosen method of dehorning, and there is a chance of causing additional stress on the calves during a crucial growth time.

However, it’s important to remember that modern dehorning methods done properly, and at an early age, will nearly eliminate stress on the calves, and will minimize your time and costs.

Cater to consumer perceptions

It’s a fact that consumer perception directs many aspects of the dairy industry’s reality. Animal rights activists have criticized dehorning for years, but it hasn’t been until recently that the general public has joined the activists’ view on dehorning as a detrimental process. With increased awareness about this common farm chore also comes increased consumer demands on how they feel farmers should handle it on their dairies.

We clearly don’t want animals with horns running around dairies, so the question is whether to dehorn calves or breed for polled genetics. Unless consumers are willing to pay a premium for milk from naturally hornless cattle, you will likely be leaving dollars on the table by selecting exclusively for homozygous polled sires if you want to ensure no animals are born with horns.

The polled gene is dominant

The basics of genetics tell us that since the polled gene is dominant over the horned gene, animals with one copy of the polled gene and one copy of the horned gene will not have horns, and a naturally hornless animal can be created in one generation. It also means it is easier to make more polled animals faster than if the polled gene was recessive.

An animal can have one of three combinations for the polled/horned gene:

PP = homozygous polled means this animal has no horns, an all offspring from the animal will be born without horns
Pp = heterozygous polled means this animal does not have horns, but offspring may or may not have horns depending on their mate
pp = born with horns

If you’re starting with only horned animals in your herd, the figures below demonstrate your results mating cows to a polled sire. The table on the left shows that a homozygous polled bull bred to a horned cow will result in 100% hornless offspring. The table on the right illustrates that a heterozygous polled sire bred to a horned cow will result in only 50% polled offspring.

Punnet square to demonstrate the resulting offspring when a homozygous polled sire is mated to a horned dam — A homozygous polled sire mated to a horned dam results in a 100% chance of polled offspring.

Punnet square to demonstrate the possible resulting offspring when mating a heterozygous polled sire with a horned dam — A heterozygous polled sire mated to a horned dam results in a 50% chance of heterozygous polled offspring and a 50% chance of horned offspring.

The downside to polled genetics

Eliminating the need for dehorning may seem like the right choice for your dairy. However, the genetic sacrifices you will make in order to get to that point cannot be overlooked. Whenever you add extra selection criteria to your genetic plan, you will sacrifice in other areas. Here are just a few reasons to think twice about selecting exclusively for polled genetics in your herd.

The continuous need for polled sires
Like mentioned above, the polled gene is dominant, so you can create a polled offspring in just one generation. What many producers tend to forget is that, at this point, maintaining a population of polled cattle in your herd is much more difficult.

As the images above show, using a heterozygous polled bull will not yield 100% polled offspring. To get to the point of a completely polled herd, and to maintain it once you’re there, you continually need to use only homozygous polled sires. This may not seem difficult, but it leads to the next shortcoming of using exclusively polled sires.

Limited availability and variation on polled sires
Since the prevalence of polled animals within the various dairy breeds is still low, it will still take many generations to genetically eradicate horned animals from your herd if you want to maintain reasonable inbreeding levels.

Even though the number of polled bulls in active AI has increased substantially over recent years, the total number of sires providing that polled gene is still limited. AI companies will only bring in bulls at genetic levels high enough to help you make progress in your herd. And since selection for polled animals has only recently gained popularity, many of the polled bulls are closely related – either from a small group of elite polled cow families or with sires in common.

Even with selection standards in place for elite polled animals, their genetic levels don’t yet match up.

Genetic sacrifice and compromised future performance
Most importantly, at this point in time, polled bulls, as a whole, don’t yet live up to the genetic levels of their horned counterparts. With polled as a strict selection criteria, you will miss out on the best sires, regardless if you select from the genomic or daughter-proven lists. When you figure the amount of production, health and conformation that could be lost by limiting your options to only polled sires, dehorning calves becomes even less of an issue.

Review your pros and cons for polled genetics

As you set your genetic plan keep in mind the pros and cons of selecting exclusively for polled genetics. At this point, the overall genetic and performance levels of horned animals still outpace those of polled cattle. Modern dehorning methods minimize stress on calves, so when performed correctly and at the proper time, it should be almost a non-issue.

On the flip side, you could make a case for exclusively polled sire selection if your milk plant is willing to pay more for milk from polled cattle, or if consumer perception drives your decisions.

Regardless of your selection decision, make sure it aligns with the customized genetic plan you put in place so the genetic progress you make on your farm is in the direction of your goals.

Sire selection vs. mating

Tuesday, May 30th, 2017

“What is the true value of a mating program?”

Many producers around the world have used a mating program within their herd for many years. However, not all producers have put that keen focus on SIRE SELECTION. If you are in that same boat, you may be missing out on the best genetics to drive profitability on your farm.

Selection vs. mating – which is more important?

Before answering this question, it is important to realize what both of these terms mean.

SELECTION – The process of documenting genetic goals to determine which bulls will help you achieve those goals the fastest. In other words, it is identifying which bulls from the available population will be utilized in your herd.

MATING – The process of choosing which individual bull (of those selected for use in your herd) should be used on each individual cow.

Mating programs generally correct problematic type traits of a cow by using a bull whose trait strengths match a cow’s weaknesses. The goal of mating is to breed a consistent herd of cows. There is great merit in consistency, but it’s easy to see that when the right sires are not SELECTED, then MATING has little impact. If you desire to improve the udders in your herd, and only select sires with poor Udder Composite (UDC), you will not improve udders, regardless of whether your cows are mated or not.

Another frequently overlooked point is that even when you SELECT the right bulls, mating also has little impact! For example, if you select only the best UDC sires for your herd, the effect of individual matings will be minimized. Even if there was no mating program in place, you would still be improving udders in your herd simply by using those udder-improving sires.

Are you sacrificing genetic progress?

The value of a mating program is questioned by many dairy farmers. One in particular, who we’ll call Joe, wants to improve the production and health of his herd. With a nice, consistent group of cows, he has determined that the conformation of his herd is already more than adequate. (This is a common thought. You too can test this in your herd by asking yourself or your herdsman how many cows have been culled for conformation reasons in the past month or past year.) For many years, Joe has had his cows mated, but never put much thought into selection.

In Joe’s case, the mating program was run by allowing any bulls from the available lineup who were at least +500 PTAM and >1.0 UDC to be individually mated to each cow. This process meant semen from at least 20 different sires always remained in the tank. Although the topic of this article is not to discuss how many sires should be used at a given time, clearly having that many bulls increases the likelihood of recording errors and reduces efficiency for the breeders.

So, will Joe make more genetic progress for production and health by continuing his current method of mating without selection? Or would he be better off selecting a group of 5-8 bulls that meet his production & health goals, and randomly using those sires within his herd? Hopefully the answer is becoming clear.

Proof in examples

To break it down in the simplest form, if you want to use two different sires on two different cows, you have two options. The first option, shown below in blue, is to mate Cow 1 to Sire A, and Cow 2 to Sire B. The second option, shown in green, is to mate Cow 1 to Sire B and Cow 2 to Sire A.

Within the table, you can see the resulting offspring’s parent average figures for PTAM and UDC. As you can see, the offspring genetic average for PTAM and UDC are exactly the same, regardless of which cow is mated to which bull. Mating option 1 will give more consistency between daughters, but mating option 2 yields exactly the same genetic average between offspring.

So once you select certain bulls, the average genetic progress of your herd will be the same in the next generation whether the group of bulls are mated to individual cows, or if one bull is randomly selected for use each day of the week.

In one more example, let’s say Joe does an experiment on his farm. He randomly selects half of his herd to breed to Group A sires, and the other half of the herd to Group B sires. Just for the fun of it, we will say that the Group B sires are mated with a traditional program, and the Group A sires are randomly selected, with one bull being used each day of the week.

Group A: 5 sires that average +100 CFP and +4.0 PL

Group B: 5 sires that average +30 CFP and 0.0 PL

The offspring from Group A sires will average 70 lbs more CFP and four extra productive months in the herd than daughters of Group B sires – even though Group A was randomly bred with no mating program. If both groups were individually mated, the difference between the offspring of each group would still be exactly the same. Daughters of Group A sires will still yield 70 lbs more CFP and four more productive months in the herd than daughters of Group B sires!

What is the value in mating programs?

The quick answer from a purely genetic standpoint is that the value in mating is minimal at best. But there are a couple benefits.

First of all, the mating staff is often the same staff with whom you set your genetic goals. Having people you trust help you design and build your genetic program is extremely important.

The second value of a mating program comes through inbreeding protection. We do not want daughters of a given bull to be bred to their brother, uncle, nephew, or worse yet their father himself! Mating programs do a good job of reducing inbreeding within your herd. However, in order to maximize this value from a mating program you must have two things in good order on your dairy:

Your Identification must be accurate – not knowing the real sire of a cow, makes inbreeding protection impossible.
The technicians must closely follow the mating recommendations. There are way too many herds that go through the process of mating the cows, but very few of those mates are actually followed.

This article is not written to discourage anyone from mating. Mating can help create a consistent group of cows. And for those interested in breeding a “great” cow, protecting faults is important.

However, if inbreeding prevention is the reason for mating, you must ask yourself if it is still necessary to have someone look at cows to mate them. Both a pen mating, which tells which bulls should be avoided on an individual animal, or pen of animals, and a pedigree mating are effective options to minimize inbreeding.

Drive genetic progress – put a plan in place

There are two important concepts to remember when setting genetic goals, and selecting bulls that fit those goals.

We cannot mate our way out of a bad selection decision
When you select the proper bulls to fit your genetic plan, you will maximize genetic progress, even with no individual matings. However it is good practice to utilize a pedigree or pen mating to ensure inbreeding is managed.

The most important concept to remember is that genetic progress is driven by the goals you set and the bulls you use on your dairy – not the individual cows to which those bulls are mated.

So in order to maximize genetic progress and profitability on your farm, be sure to spend at least as much time setting your genetic goals and defining your selection program as you do on your mating program.

Genomic Selection Improves Heat Tolerance in Dairy Cattle

Thursday, September 29th, 2016

Dairy products are a key source of valuable proteins and fats for many millions of people worldwide. Dairy cattle are highly susceptible to heat-stress induced decline in milk production, and as the frequency and duration of heat-stress events increases, the long term security of nutrition from dairy products is threatened. Identification of dairy cattle more tolerant of heat stress conditions would be an important progression towards breeding better adapted dairy herds to future climates. Breeding for heat tolerance could be accelerated with genomic selection, using genome wide DNA markers that predict tolerance to heat stress. Here we demonstrate the value of genomic predictions for heat tolerance in cohorts of Holstein cows predicted to be heat tolerant and heat susceptible using controlled-climate chambers simulating a moderate heatwave event. Not only was the heat challenge stimulated decline in milk production less in cows genomically predicted to be heat-tolerant, physiological indicators such as rectal and intra-vaginal temperatures had reduced increases over the 4 day heat challenge. This demonstrates that genomic selection for heat tolerance in dairy cattle is a step towards securing a valuable source of nutrition and improving animal welfare facing a future with predicted increases in heat stress events.

The top three ways to make genetic progress

Friday, August 5th, 2016

Progress is a good thing, and in regards to genetics it’s no different. Genetic progress has been the topic of conversation as much in the past several years as ever before because of how it relates to and results from genomics.

In the simplest of terms, genetic progress is making better cows, faster. And just how do you go about progressing your herd’s genetics? The answer lies in the fact that the equation for genetic progress depends solely on four factors.

The equation for genetic progress

Selection intensity: the proportion of the population selected to become parents.

Do you use artificial insemination rather than a herd bull? Do you code cows with poor production, udders, or feet and legs as Do Not Breeds? Do you flush your best females and use your low end animals as embryo transfer recipients?

A yes to any of these questions means you are increasing selection intensity on your dairy by simply being more selective on which males and females you choose to be parents of your next generation of cattle.

Accuracy of selection: the average reliability of genetic evaluations used to make decisions about parents of the next generation of animals.

In the world of genetics, accuracy is primarily measured in terms of reliability. And in terms of genomics, accuracy is a function of the size of the reference population that is used to compare against a genomic-tested animal. Currently, the genomic reliabilities for production traits are often 70% or greater in North American Holsteins, which is twice the level of reliability that we used to achieve with traditional parent averages computed based on pedigrees.

Genetic variation: the degree of difference that exists between the best animals for a given trait and the worst animals for that trait.

If all animals were clones of one another, the variation among animals would be zero, and the opportunity to make genetic progress in any and all traits would cease to exist. Different genetic makeups and pedigrees lend way to variation among animals.

Genetic variation can be quite different from one herd to another. A herd that has used a focused genetic plan to select AI service sires for many years will have much less variation than a herd that has purchased animals with unknown pedigrees.

In comparison with other factors in the equation for genetic progress, little can be done to increase the amount of genetic variation within a given population. However, since inbreeding decreases the effective population size, by avoiding overly excessive inbreeding levels we can prevent a decrease in genetic variation.

Generation interval: measured as the average age of the parents when an offspring is born.

As the prevalence of genomic sires has increased over the past five years, the generation interval has been on the decline. Now, instead of waiting a minimum of 4.5 years to use traditional progeny-tested bulls, both farms and AI companies can more confidently make use of genomic-tested bulls in their on-farm AI programs or as sires of sons by the time an elite sire is roughly one year of age, decreasing the generation interval on the paternal side by more than three years.

So to put these factors of the genetic progress equation into play on your farm, what management strategies can you implement to make the most genetic progress possible?

1. Set your own genetic plan

You can make genetic progress in a variety of ways. First and foremost, you want to ensure you’re making progress in the right direction. To do this, set your own customized genetic plan, placing your selection emphasis only on the traits that matter to you – whether that’s production, health or conformation, and any specific traits within those categories. This way, you’ll not only make progress, but it will be in the direction of your goals in order to maximize progress and profit on your dairy.

2. Use the best bulls to suit your genetic plan

Once you’ve set your genetic plan, select the best bulls to fit that plan. You can take advantage of the amplified selection intensity put into place by your AI company, knowing that from the thousands of bulls they are genomic testing each year, they select only the best of the best to be parents of the next generation.

If you also select only the elite sires that fit your genetic plan from your AI company you maximize your on-farm selection intensity as compared to using just any cheaper bull off the proof list.

3. Utilize a group of genomic proven sires as part of your genetic program

There is no need to fear genomic-proven sires. By making use of the best and brightest genomic-proven sires available, you make strides in all areas of the genetic progress equation. You decrease the generation interval as compared to waiting to use daughter-proven sires. You also step up the genetic selection intensity on your farm.

The accuracy gained from an ever-growing reference population of genomic-tested males and females is another benefit of selecting from a group of genomic-proven sires. And by utilizing a group of these sires, rather than one individual, you can maximize the genetic variation when pedigrees differ among them.

There are certainly more ways than these to make genetic progress in the females of your herd. However if you implement these top three easy ways to make genetic progress on your farm, you will increase selection intensity, accuracy and variation, while decreasing generation interval. The progress you make will be in the direction of the goals you’ve set for your farm and you’ll capitalize on the genetic profit and progress potential.

Should You Breed for Feed Efficiency?

· Comments (0)

Wednesday, July 27th, 2016

Feed costs account for nearly 55% of the daily cost for a milking cow. As well feed costs contribute to a significant portion of daily costs for calves, heifers, and dry cow. Daily margins are currently under severe pressure, and it is only a matter of time until breeders start asking their genetic suppliers for facts and figures on how to select for animals that are superior for converting feed into growth, milk and milk solids. Breeders are now hearing or reading claims by breeds, genetic suppliers, and even other breeders that their genetics are the best buy for feed efficiency. But is there evidence to support those claims?

The Bullvine feels it is time to collect and comment on some of the known facts and the areas where breeders can expect to see information on feed conversion efficiency.

What History Tells Us

Breeds of dairy cattle have been developed over centuries and are an adaption of bovines to the regions they originated from. Whether is was an island, country or continent, all breeds were developed mainly based on the climate, the crops available or the milk and/or meat products produced. Measurements such as feed intake were not collected on an animal by animal basis to determine which animals were the most efficient at converting what they ate into meat or milk.

So, in fact, history tells very little about any breed’s feed conversion abilities or any of their differences in ability to convert feedstuffs to meat and milk energies that humans can utilize. The data for analysis does not exist. Therefore, to date, breeding for feed conversion efficiency has been by impression or at best by indirect selection using other documented traits.

Feed Efficiency – What is It?

Michael VandeHaar from Michigan State and his five associates (from U of Wisconsin, Iowa State, MSU and Wageningen UR) have produced a very complete and forward-looking paper called ‘Harnessing the genetics of the modern dairy cow to continue improvements in feed efficiency.’ They published it in the Journal of Dairy Science in April 2016 (JDS 99:4941-4954). Some summary excerpts from that paper follow.

“Feed efficiency is a complex trait for which no single definition is adequate. Generally, feed efficiency describes units of product output per unit of feed input, with units being mass, energy, protein or economic value. For dairy cattle, the primary product is milk, but the energy or value of tissue captured cannot be neglected. Losses or gains of body tissue can result in misleading values of feed efficiency if the only product considered is milk. Feed efficiency should be considered over the lifetime of a cow and include all feed used as a calf, growing heifer and dry cow and all products including milk, meat, and calves.”

There is much to consider in the previous paragraph, but VandeHaar also adds “In addition, we should consider that feed efficiency is more complicated than just feed and product. At the farm level, economic efficiency is clearly a priority.”

More Facts about Feed Efficiency

VandeHaar and Associates also report.

“Feed efficiency, as defined by the fraction of feed energy or dry matter captured in products, has more than doubled for the US dairy industry in the past 100 years.
This increased feed efficiency was the result of increased milk production per cow achieved through genetic selection, nutrition, and management, with the desired goal being greater profitability.
With increased milk production per cow, more feed is consumed per cow, but a greater portioned of the energy is used toward milk instead of maintenance or body growth.
The dilution of maintenance has been the overwhelming driver of enhanced feed efficiency in the past, but its effect diminishes with each successive increment of production relative to body size and therefore will be less important in the future.

Predictions about the Future for Determining Feed Efficiency

VandeHaar and Associates make some interesting predictions about the future relative to feed efficiency.

Research will be needed on new ways to enhance digestive and metabolic efficiency. One way to examine the variation in efficiency among animals is the measurement of residual feed intake (RFI) a measure of efficiency that is independent of the dilution of maintenance. Study on about 6000 cows by the VandeHaar team has identified that RFI is 17% heritable – so there is definitely the possibility to improve animals through genetic selection.
Cows that convert more efficiently and, thereby, are potentially more profitable, will also need to be healthy, fertile and produce a product that generates high revenue.
Genomic technology will help to identify the animals that have high genetic merit and therefore the animals to be used as parents in genetic improvement programs.
At the farm level, nutrition and management will continue to play a major role in feed efficiency. Animal groupings and precise nutrient balancing in group TMR’s will play a role.
New computer-driven technologies that consider genomics, nutrients, management, grouping and environment will be a reality.

All of these facts make us realize that much more work must be done on feed conversion efficiency before is can be applied at the farm level.

It Goes Beyond Feed

The Bullvine called on Jack Britt Ph.D. for input on the topic of feed efficiency. He is a very respected agricultural consultant and formerly a scientist, teacher, and leader at three universities.

Britt comments include:

The use made of the milk produced is significant. Farm gate revenue can be maximized with high solids milk for cheese production, whereas lower solids milk is likely best when the use is liquid.
Conversion feed efficiency must be considered along with a host of other factors, beyond genetic, nutrition and management, including methods of harvesting forages; climate and environment; animal housing; and economics
As yet there is not enough data to know if feed efficiency for maintenance and growth is different than feed efficiency of milk production. Therefore, selecting for RFI based on milk production may or may not result in less feed for maintenance and growth in heifers and young cows.
For the immediate future, producers need to focus their attention on factors they can control including profit per cow per day; feed quality; dry matter intake; cow comfort; enhanced management techniques; improved reproduction; animal health and increased production.

Some Salient Facts

In our study of this topic, The Bullvine has noted the following important facts:

We can not expect to have feed conversion data for all cows. Measuring exact input and outputs for individual cows is costly. There may be hope regarding estimating feed intake. Dr. Jack Bewley (Kentucky) is currently researching using remote camera technology to capture changes in feed volume in front of cows.
Both inputs and outputs are important. It is profit per cow, per group or per herd that drives viability and sustainability. In the immediate term, producers are advised to think and manage regarding income over feed costs (IOFC) or return over feed cost (ROF) on a per cow, per group or herd basis.
Breeders can expect to see various terms used to rank sires and cows for their feed conversion efficiency. The formulae for these rankings, at this point, have only limited scientific backing.
Large cows must produce more milk than smaller cows of the same breed to have equivalent feed efficiency.
Changes in body condition scores must be accounted for in estimating feed efficiency because a cow losing condition will appear to be more efficient than one gaining condition if only feed intake is measured.

The Bullvine Bottom Line

Accurate genetic information on feed conversion efficiency of dairy cattle is in its early stages. Making decisions on selecting animals for this is not recommended at this time. Expect to see genomic animal ratings in the coming years but take care to consider the accuracy of those ratings. If and when there are reliable feed efficiency indexes, expect to see them included in total merit genetic indexes like NM$ and Pro$. The answer to the question is “NO”. Breeders should continue to focus on breeding, feeding and managing for profit using the tools currently available.

Sire Selection: Work with the best and forget the rest!

· Comments (0)

Tuesday, July 19th, 2016

There is considerable debate among dairy cattle breeders, whether breeding is an art form or science? With most telling you it takes a combination of both to achieve sustained success. The question becomes how you can improve your current breeding program to go from good to great? The answer lies in your sire selection intensity. When you work with only the best sires you will achieve the greatest success.

Dairy cattle breeders use science and numbers every day when they go about selecting a bull to use or when they cull a female from their breeding program. The rigor and intensity of these two acts has a great bearing on the genetic progress that a herd can make. When it comes to the genetics added to or removed from a herd, the question every breeder must continually ask is – “Am I being demanding enough?”.

You have to Apply the Science or Lose Genetic Progress

In measuring genetic progress, four factors are considered: a) the superiority (or inferiority) of the animal selected (or culled); b) accuracy, on a genetic basis, of the information used; c) genetic variation for the trait under consideration, and d) the generation interval from parents to progeny. The sum of a, b and c is divided by d to get an annual genetic gain.

The superiority of the animals used as parents is a vital factor over which a breeder has control in genetic improvement in a trait. Only using the very best sires and dams when adding females to the breeding herd will move a herd forward rapidly for the traits under consideration. This is referred to as the intensity of selection. (Read more: The Genomic Advancement Race – The Battle for Genetic Supremacy Sire vs. Dam – Which has a Greater Impact on Your Herd’s Genetic Improvement?, and Impact of Genomics on Genetic Selection and Gain)

Why You Should Care about Genetic Improvement

In the future, dairy cattle breeders will be more interested in their overall herd improvement rather than in producing one or two breed list toppers or show winners, while being satisfied with their herd being just average. The focus will be on total farm profit. The dairy cattle breeding industry is seeing this change already where breeders are following programs that use sexed semen, use only top indexing sires, use only implanted embryos from elite females, use low indexing females as recipients or mothers of beef calves and select for the future generations based on economically important traits.

A.I.’s are doing the same. Some A.I.’s are breeding to get breed topping males, and others are breeding to produce top males and top females. These breeding companies want their products to provide their customers with the opportunity to maximize profit in the era of narrowing margins, automation, guaranteed product quality and feeding a hungry world.

Where the maximum rate of genetic improvement was once thought to be 1% per year, it can now be 1.5% for some traits in both Holstein and Jersey populations.

Recent rates of genetic improvement are as follows:

Breeders are effectively using genetic information to make significant improvement and, therefore, that rate of improvement is speeding up. From studying sire usage in recent years, we know that the rates will increase even more.

Is Genetic Improvement REAL?

For those breeders who question whether genetic improvement is being made, here are five places it can be seen:

type in the show ring
a lower percent of low producing first lactation cows in herds
improved type animals in milk production herds
elite brood cows leaving not two or three but many high daughters and sons, and
many more top indexing unproven sires are leaving top daughters and sons.

Focus, Focus, Focus on Traits Needing Improvement

In 2021 dairy farming will be considerably advanced. The cows in the herds then will face different conditions.

Increasing use of automated systems where each worker will be covering twice as many cows.
Improved animal health and disease resistance to ship milk
Animal fertility will be improved as seen in calving ease/days to first heats/conception rates
Cows, on average, will complete four lactations (currently it is less than three)
New traits will be available for breeders to use (Read more: Can you breed a healthier cow? and The Complete Guide to Understanding Zoetis’ New Wellness Traits – CLARIFIDE® Plus)

Given this scenario, The Bullvine recommends that breeders consider placing their focus on three or four of the following traits.

Fat yield
Protein yield
Productive Life / Herd Life
Daughter Pregnancy Rate / Daughter Fertility
SCS and animal disease resistance
Daughter Calving Ease / Daughter Calving Ability

These are key traits in order to drive up revenue or decrease expenses and extend the average length of herd life on a per cow basis.

Readers will note that The Bullvine has not included total merit indexes (TPI, JPI, LPI, NM$, CM$ or Pro$) in its trait list. The reason for not including such indexes is that they are a sum of all traits included in them, and thereby there can be animals with high total merit indexes, but that can be deficient for traits recommended in the previous list.

When Good is NOT Good Enough

Sires used today do not have milking daughters until three years from now. Their indexes must be significant pluses today just to be average by then. For example, in North America Holstein and Jersey sires must be +30 lbs fat today to be average in 2019. For PL it would be +1.75 for a US Holstein sire and for CONF it would be over + 4 for a Canadian Holstein Sire. In general, a sire needs to be 10% – 20% above the current average for a trait in order to be just average when his daughters are in their first lactation.

But average today in three year’s time will not be good enough!

The Bullvine recommends that sires used today have at least the following indexes:

Dignitary	7JE01150	102	81	55	2.68'	103	102	1571

Breeders should set up their own list of focus traits. On-farm profit focused breeders will focus on traits where their current herd is not genetically high. While show breeders everywhere may wish to select for Holstein cows with less stature but correct conformation as 60 inches (150 cm) may be the ideal stature in five years’ time. After viewing, on-line, the animals at the recent EU Championship Show, it appears that EU breeders have already adopted having less extremely tall Holstein cows.

Since the genomic sire lists change almost monthly, it serves only a limited purpose to provide a list of top genomic sires. The Bullvine recommends that the values in Table 3 be increased by 25% for genomic sires to help balance out for the lower accuracy of the indexes. Of course the industry standard recommendation applies, do not use only one genomic sire in a herd. It is much better to buy ten doses from each of five genomic sires than fifty doses from only one genomic sire. (Read more: 4 Steps to Faster Genetic Improvement)

The Bullvine Bottom Line

Using AVERAGE sires is not good enough especially when there exists the opportunity to have many more top animals in your herd by using sires that EXCEL. This also applies for the female side of breeding. Increasing the genetic merit levels required for animals selected as parents of the next generation will always pay big dividends. By taking these actions and increasing your selection intensity, you will take your current breeding programs from good to great and see enduring success.

4 Steps to Faster Genetic Improvement

· Comments (0)

Tuesday, May 24th, 2016

I often see on Facebook or in the Milk House discussion group where a breeder shows a picture and perhaps some of the achievements of a cow or heifer and then asks Facebook friends or other Milk House members for suggestions on a sire to breed or flush her to. Personally, even though I love mating dairy animals, I do not answer these requests. This is not because I don’t have an opinion but because I seldom know what the animal’s performance or genetic facts are and, more importantly, I don’t know what the owner’s goals are.

For me, there are four important steps involved in improving an animal or a herd: 1. Measure first 2. Set goals 3. Narrowing the list of sires 4. Choosing the best mate for your cow.

Step #1: Measure First

Dairy cattle improvement long ago moved past the practice of only doing a quick visual of an animal before selecting a sire to improve one or two physical characteristics. The modern dairy animal is a complex milk producing machine that must tick many boxes to return maximum lifetime.

Until genomics arrived on the scene in 2008, the vast majority of breeders were satisfied to simply know the animal’s recorded performance in the milk pail and, if not official type classification, then at least any observed type weaknesses that the animal possessed. Over 95% of breeders used the actual performance results and not the genetic indexes for production and type traits when breeding cows.

With genomic indexes has come a rapid increase in the number of traits for which genetic indexes are available. No longer are production, SCS and type the only primary traits considered in improving the genetics of an animal or a herd. In fact, for the majority of owners, those traits are today taking a back seat to additional traits such as reproduction, length of life, milking speed, inbreeding and age at first calving. As yet owners are still, in 2016, using the phenotypic value when measuring and not the genetic value for these new, front and center, traits.

The saying goes “you cannot improve what you do not measure”. Measurement has vastly improved and today much can be learned in the two years from conception to first breeding and the four years from conception to end of the first lactation. Today the question is, “Which traits are most worthwhile?” You have the option of considering feed conversion efficiency, haploids that affect fertility, age at first heifer estrus, protein composition, fat composition, ratings on early embryonic death and perhaps fertility in the very high producing cow. These are a few in an ever growing list.

In 2020 knowing a few basic facts will no longer be enough to succeed. By that time, the scope of what traits are measured will expand considerably. Breeders planning to have their herds remain current in the population will need to be measuring more and more traits. Services for measuring will no longer be only breeds and DHI, many new service providers are now or soon will be on the scene (Read more: WILL GENETIC EVALUATIONS GO PRIVATE?)

Step #2: Set Goals

The Bullvine regularly urges dairy breeders to have a breeding plan for the herd. (Read more: What’s the plan?, Are you a hobby farmer or a dairy business?, and Dairy Cattle Breeding Is All About Numbers). Just as frequently we hear back from our readers regarding their plans. Recent reader shares have told us about wanting to decrease the average mature stature of their Holstein cows. Other have shared that they are breeding for a totally polled or A2A2 Kappa-Casein herd. Still others want purebred Holsteins that conceive when milking heavily like they did half a century ago. By the way, keep those letters on goals flowing to us.

The point we wish to make in this article is that you will never arrive at your breeding goal if you do not have a plan to get you there. Take the time right now, perhaps while you are relaxing after first cut hay, to do a complete and realistic breeding plan for the next five years. Having a plan will mean that the next two steps, #3 Narrowing the list of sires and #4 Choosing the best mate for your cow, will be much easier and will have a much greater chance of being successful. A plan can be either a whole herd plan or for a portion of the herd. For many breeders, the plan may vary from cow family to cow family. In all cases, the plan should include the three (maximum five) traits that are to receive primary emphasis. Most A.I. companies have trained individuals who can work with owners to define the genetic goals, and thereby the plan, for the herd.

Step #3: Narrowing the List of Sires

It is no longer effective to choose sires simply from the top five TPI, LPI, NM$, Pro$, CM$, PTAT or DWPS$ sires and hope to achieve the goals set in #2 (above). “Why isn’t it possible?” you ask. A quick check shows that if your goal is to significantly improve your Holstein herd’s genetic merit for fertility, thus requiring a bull be one standard deviation about average, there are only two of the top five Pro$ sires that can do that. Choosing three of the top five means defeating your plan. And if your goal is to improve your herd for SCS, there are three of the top five proven Holstein TPI have a SCS index of over 3.00. You must zero in specifically to be successful.

Total merit indexes are an excellent guide to narrow the list of sires to be considered for use in a herd. After narrowing your list of potential sires to the top 25 for the total merit index of your choice then eliminate all sires that are NOT significant improvers for your three primary traits.

Here are some example primary traits and minimum rating for a sire to be classified as a significant breed improver.

Table 1 Minimum Index Values for a Holstein Sire to be a Significant Improver

CDCB Evaluations		CDN Evaluations
DPR	2.5	DF	106
PL	4	HL	106
UDC	2	MS	6

It does not matter how popular, how marketed or how high a sire is for TPI or LPI if he has genetic indexes that are significantly above average for your primary traits, then he’s not for you.

Achieving your genetic plan should be Job #1, when it comes to which sires to buy semen from. Two rules of thumb included: 1) semen price should not deter you (five doses of $100 semen will be quickly paid back when the one daughter gets in the milking herd); and 2) do not over buy on number of doses (with three index runs a year, there are always new top sires for your primary traits coming available.) If you don’t have the semen from former leaders in your tank, then you will not be tempted to use it. Genetic advancement has never been as fast as it is today. We can expect it get even faster. Don’t hold your herd back in the past.

Step #4: Choosing the Best Mating for your Cows

The Bullvine recommends that breeders find a mating program that uses genetic indexes for both sires and cows or heifers and that allows breeders to place added emphasis on their primary traits. Most A.I. companies have a mating program that can be adapted to a breeder’s genetic plan, and that can use any sire no matter what their ownership.

The objective should be to mate individual cows to one of the sires that have the superiority in your primary traits (see #3 above). It makes little sense to mate your -1.0 DPR cows to a sire that is less than +3 .0 DPR even if there is a remote possibility that you may get one daughter that wins your county show. County show winners most often can not garner extra dollars in the sales ring. But cows that are above average for DPR can stay in the herd longer and thereby achieve higher lifetime profit.

The Bullvine Bottom Line

All four of these steps are integral in being successful in achieving genetic advancement in your herd. You will have financial rewards every year and, as well, you will be rewarded by passing on a genetically superior herd to your successors or when you decide to sell your herd.

Can you breed a healthier cow?

· Comments (0)

Tuesday, March 1st, 2016

The most profitable cow on most farms is the cow the gives the greatest amount of milk but goes almost unnoticed because they do so while breeding back year after year without adverse health events. That challenge, until now has been that we cannot accurately genetically identify these animals, until now. Breeders are asking their breed societies to do research that helps identify these cows earlier in their lifetimes.

Profitable dairy cows are fertile, productive and require minimal extra inputs to maintain their health throughout all phases of their lives. The challenge is that the current genetic evaluation and selection systems in dairy cattle have primarily focused on production traits such as milk and protein production with only indirect predictors of health (e.g., somatic cell score, productive life,). Sure we know which cows give the most milk, and what cows last the longest, but the modern dairy cows are less ‘robust’ than previous generations. That is because we have been unable to accurately assess the genetic risk factors for economically relevant health challenges in Holstein cattle.

To accurately identify which cows last the longest and are the least amount of trouble we need to look at the top reasons producers cull cows. The top known genetic component reasons for culling or removing cows are:

Low production 19.6%
Reproduction problems 15.1%
Mastitis 12.9%
Locomotion problems 4.5%
Undesirable conformation 0%
Bad behavior 0.1%
Unspecified reasons 30.6%

Yet except for reproduction, for which we have (Daughter Pregnancy Rate), we currently have no direct trait to predict mastitis, lameness, retained placenta, displaced abomasum and ketosis. Even DPR does not account for such reproduction issues as metritis. However, all this is about to change as Zoetis has now introduced their new wellness trait evaluations as part of their CLARIFIDE® Plus genomic testing. (Read more: ZOETIS LAUNCHES CLARIFIDE® PLUS)

What Has Changed

Zoetis has introduced six new traits that are directly connected to the key wellness issues that producers encounter. The new traits are Mastitis, Lameness, Metritis, Retained Placenta, Displaced Abomasum, and Ketosis. None of these have had a direct trait to assist in genetic selection decisions on who to keep and making breeding decisions on in the past. This new single genetic test will provide U.S. Holstein producers with direct comparable and viable assessment tools for assessing the genetic potential for production, health, fertility, longevity, and profitability like we have never seen before. Producers will be able to use genomic information for more comprehensive heifer selection and breeding decisions.

When you consider that the cost of a single instance of mastitis is between $155 – $224 per case and that it occurs in 12% to 40% of lactations, the ability to now accurately make direct breeding decisions on this issue is truly game changing. How many times have you had to cull a cow because she retained her placenta, got metritis and would not breed back and yet you had no way of knowing if she was genetically more predisposed to it than others animals? Well, now you will know.

Where does the data come from?

Genomic predictions for wellness traits have been developed by Zoetis based on an independent database of pedigrees, genotypes and herd records assembled from commercial dairies and internal assets. The database incorporated primarily large commercial U.S. dairy operations and included more than 10 million lactation records; 4 million cases of mastitis; 3 million cases each of metritis, retained fetal membranes, displaced abomasum, and lameness; more than 1.9 million cases of ketosis; and more than 15 million pedigree records.

Health events were assembled from on-farm dairy herd records provided with consent by commercial dairy producers. Data editing procedures to convert documented disease incidence to a standard format were developed based on a review of event codes in on-farm herd management software and in consultation with dairy production and veterinary experts.

Private vs. Independent Database Accuracy and Reliability

The first thing that will occur to many breeders’ minds is that this is a private or selected database. While the database is certainly more from commercial than seed stock herds, it is in no way selective with any inherent herd biases. While some metrics produced by AI organizations could come from a selective data set, this independent database is derived from a broad spectrum of herds. As well thanks to the parentage verification of genomic testing has already accounted for the large percent of records that might have been miss-identified.

Also, all the data talks to each other in one step, vs a 2 step process, allowing for more reliable results with the same amount of data. This is a cutting-edge genetic evaluation method that has become the new gold standard, and requires a lot of computer power to do.

Don’t Forget Polled

In addition to wellness traits, the new CLARIFIDE Plus includes information for the Zoetis proprietary Polled trait. Results will indicate animals as either tested homozygous polled, polled carriers, tested free of polled or indeterminate. This is an even more conclusive polled test than other options as it contains a wider range of markers for the polled gene than other options currently on the market.

Two New Dairy Wellness Indexes

Zoetis is also introducing two economic selection indexes based on these six new traits. They are:

Wellness Trait Index^TM (WT$^TM)
This multitrait selection index exclusively focuses on the new wellness traits (Mastitis, Lameness, Metritis, Retained Placenta, Displaced Abomasum, Ketosis, and Polled) and directly estimates the potential profit contribution of the wellness traits for an individual animal that will be passed on to the next generation.

Dairy Wellness Profit Index^TM (DWP$^TM)
This multi-trait selection index includes production, fertility, type, longevity, calving ability, milk quality and the wellness traits, including Polled test results. By combining the wellness traits with those found in the current Net Merit (NM$) index, DWP$ directly estimates the potential lifetime profit contribution an individual animal will pass along to the next generation. DWP$ identifies greater genetic variation around profitability than other industry indexes due to greater description of the actual disease risk.

Using DWP$ for selection decisions can have significant financial impacts on the dairy by increasing expected profit per cow by an extra $53,000 when compared to no selection strategy for genetic selection based on NM$ parent average. In fact, DWP$ also outperforms using NM$ as your selection index with 15% cull rate by over $55 or 44% greater lifetime return.($185.65 vs. $129.72)

The Elephant in The Room

For many breeders when they choose to genomic test there are two parts to it. Firstly, there is the ability to make culling decisions, which these new six traits and two indexes will assist in. However, the second part is the ability to make breeding decisions. The challenge is that currently there are only values for your animals and any sires you wish to mate your animals to do not have publically available indexes for these traits. For example, currently if you identify that you would like to improve on lameness issues, you can cull problems, but there is nowhere to find out which sires are genetically superior for lameness. When I asked Zoeits about this, they explained that they are indeed talking with AI units about the potential for them to test or obtain this information. However, just now the data is not available.

It will be interesting to see if Zoetis goes the route that Semex has gone with Immunity+ Plus where it became a sole use for one AI unit, or will it become like Sexing Technologies has done with Sexed Semen where they license the technology to all partners, with each putting their branding on the process. Zoetis has commented that “we are open for business” to provide testing for customers wanting our new CLARIFIDE Plus outcomes for both females and males. The offering will be commercially available for Holstein dairy cattle and we are looking forward to overall industry adoption.

The Bullvine Bottom Line

For years many producers have been screaming for these traits and the industry side has been hesitant for two main reasons: 1) low reliability for health and management traits, and 2) the lack of verifiable data. All this data is based on user generated information and has not been supervised by any testing organization like milk recording or breed associations. The lack of supervision indeed does enter the possibility for bias, but with genomic testing, that bias is certainly minimized. While it appears that this change would put Zoetis in direct competition with the likes of CDCB, they insist that is not their intent, but rather they are moving to develop their differentiated solution that is more ideally fitted for modern commercial producers to complement the other core CDCB information.

One thing is for sure, with the introduction of these six new traits, breeders have greater insight into exactly what causes many of the profit-robbing and labor-intensive events that have never been accounted for under the current genetic evaluation system. While it will be interesting to see how the industry responds to this, there will certainly be some significant changes to the genetics industry in the weeks and months to come.

Are We Getting Desired Genes Into Our Cattle?

· Comments (0)

Monday, February 15th, 2016

Livestock genetic improvement is all about increasing the proportion of desired genes in the animals that breeders have on their farms. Even though this process has been occurring since animals were domesticated, it has only been documented over the past couple of centuries. With the vast majority of the improvement in yield occurring in the past seventy years.

The challenge that today’s breeders must address is how they will choose to further eliminate the unwanted and increase the proportion of desired genes in our milk producing animals. This applies to all species – bovine, buffalo, goats, sheep and yes even yaks, reindeer, and camels. Today few of us think of breeding dairy animals that are specific to their environment.

Dairy cattle breeding has gone through many stages to arrive at where we are at today with top cows that can produce over 2,200 pounds (1,000 kgs) of total fat and protein in a single lactation or have near perfect conformation.

The Bullvine looks both back and ahead at selection tools.

Advancements Made In Selection

Natural selection was a start but only a small start. Since then breeders had worked to develop animals and breeds using such tools as measuring performance, selecting sons and daughters from top cows, culling bottom enders, buying the best herd sire available, inbreeding followed by outcrossing, linebreeding and sharing elite bulls amongst an ownership group. With all of these breeders used what their eyes told them or the actual measured performance. (Read more: 6 Steps to Understanding & Managing Inbreeding in Your Herd, The Truth about Inbreeding and Stop Talking About Inbreeding…)

Significant genetic gains have occurred since WW II when breeders joined forces to jointly work to goals and geneticists analyzed the data to determine which animals had the best genetic make-up. The sampling of young sires from elite parents moved the dairy cattle breeding industry far along the journey to having cattle capable of producing over three times their previous yields. Recently an American cow is credited with 74,650 lbs of milk, 2,126 lbs of fat and 2,142 lbs of protein in 365 days. That’s almost 205 lbs (93 kgs) of milk per day for an entire year. And it seems almost every month now that we hear about cows scoring EX95 to EX97 in numerous breeds and countries.

Cloning was a tool tried, but the cost and the fact that an animal was replicated but not improved left it in the tried but of no use garbage bin. On the other side, there is sorting of semen by sex which now is nearing perfection for producing the sex of calf desired and matching unsexed semen for the ability to obtain a pregnancy.

The opportunity for improving the genetic ability of dairy cattle took a significant step forward in 2008 when genomic facts were added to the genetic evaluation process. The animal genomic information was added to the pedigree, classification and milk records resulting in genetic indexes with 60-70% accuracy where they formerly were 30-35%. Not since the change from only using visual observation to using parent, classification and milk records as the basis for decision had the accuracy of predicting genetic merit doubled.

Will Improvement Continue?

Where will the process of changing animals all end? Well, it won’t end.

The race to having a higher and higher proportion of animals with the genetic makeup that will maximize profit in tomorrow’s world will continue.

What Tools Are On The Horizon?

Already here is crossbreeding. Many breeders have been experimenting with taking genetics from top animals in pure breeds and crossing breeds. From a Holstein base, which is the case in most countries, numerous other dairy breeds are being used on a rotational or backcross basis to improve animals especially for health, fertility, longevity and other management traits. Without effective alternatives for selection from within breeds, crossbreeding schemes are likely to become more prevalent as a way to lessen the need for individual animal care, minimizing some of the added costs associated with high production and having animals that will perform in more rugged or extreme environments.

For some dairy farmers a new breed may be the answer. In New Zealand the Kiwi Breed (a combination of Holstein and Jersey) now makes up 50+% of the dairy cow population. It could be that Kiwi or some other composite breeds may come into popular support in other countries. Could it even be that in some regions of the world there is a return to dual purpose animals, breed for both milk and meat? (Read more: Holstein vs. Jersey: Which Breed Is More Profitable?)

Gene editing as a means of changing the genetic makeup of living beings is in the popular press at this time. The February 2^nd National Post described gene editing as “… using tools to precisely edit genes inside living cells”. The National Post article added “There are a few methods but the technique known as CRISPR-Cas9 is a relatively fast, cheap and simple method that many researchers are keen to try”. On the human side the possibility for ‘genetic’ cures to miscarriages, infertility, HIV, MS, sickle cell disease and many others are a great hope. On the animal side fixing the problems by gene editing at the embryo stage sounds interesting at this moment.

Breeders and breeds need to be prepared for gene editing, perhaps as early as the next decade. For breed loyalists concerned about breed purity, it could be that the edited genes could come from selecting the ‘good’ genes from within a breed. I have had breeders, mainly in topical countries, wonder if the high milk solids percentages and heat resistance of the water buffalo could be added to our dairy cows. At this time there is are only questions and speculation. However progressive breeders always have and always will look to new techniques, as they come along, to make sure our dairy animals have the best genes possible.

What Cows Could Be On The Horizon?

Do we actually know what our dairy animals will be in the future? In fact, … NO!

But we can speculate. The Bullvine has produced many articles on what the dairy cow will be in the future. (Read more: She Ain’t Pretty – She Just Milks That Way!)

The Bullvine Bottom Line

Improving the genetics of dairy cattle will not go away or stop. The dairy cattle breeding industry needs to be open minded when it comes to the tools and techniques that will be used to make the cows of the future.

Why Balance Breeding is No Longer Relevant

· Comments (0)

Wednesday, December 9th, 2015

In the 1960’s “Best to Worst” for conformation and production ranking revealed that there was a wide range in all dairy breeds. There were first calf Holstein cows that lost their median suspensory ligaments at calving time. There were Jersey first calvers that did not produce even one pound of butterfat per day. Our dairy cattle have come a long way forward in the past half century.

Balanced Breeding Got Us Here

The bottom end cattle in all breeds have disappeared. Those tail-enders were still here until the early 1980’s but then the Balanced Breeding approach came into vogue. With it came the use of genetic indexes for both production and type. This meant that genetically inferior daughter proven sires were no longer available from AI companies. Young sires only entered organized sampling programs if they had superior parent averages and progressive breeders used genetic indexes in breeding, marketing, and culling. The saying “We’ve come a long way baby” now rang true. Balanced Breeding started in North America but soon became global. Today the question has changed to “Will Balanced Breeding Still Be Relevant in 2020 and Beyond?”

What is Balanced Breeding?

Originally Balanced Breeding meant that equal emphasis was placed on type and production (milk and fat present) when making a breeding decision. It followed the breeding era when breeders would place the entire emphasis on either type or production. Yes, either or, and never the twain did meet. So even a program that placed 50% emphasis on each of type and production was a significant step forward.

Balanced Breeding usually meant using sires that did an overall good job of producing above average, but not exceptional, progeny.

Total Merit Indexes Fit the Balanced Breeding Approach

In the 1990’s total merit indexes were developed by genetic evaluation centers and breed societies to bring a reasoned and balanced means of ranking both males and females. What started out as a type and production index (often called type production indexes) has now been expanded to include many traits beyond type and production. Today every dairy cattle breeding country has, at least, a couple of total merit indexes that are routinely being fine tuned as more genetic indexes come along for more traits or as research shows that revisions are needed in trait emphasis. (Read more: EVERYTHING YOU NEED TO KNOW ABOUT TPI AND LPI)

In fact, today it has reached the stage where there are so many total merit indexes published that bottom line focused milk producers can feel confused, dismayed or even that their genetic improvement needs are being ignored. With 20% of dairy producers producing 80% of the milk in many developed dairy countries, it is important that the genetics needed and used by milk producers not be ignored by bull breeders, female replacement breeders, and genetic markets.

Once again The Bullvine is asking, “Is the Balanced Breeding approach still relevant for milk producers?”

The Problems with Balanced Breeding

What it boils down to is that total merit indexes are a one size fits all approach. However, herds do not have the same levels of genetic merit for all traits. They do not have the same culling reasons. They do not have the same profit-loss scenarios. One size does not fit all. Add to that the fact that to improve below average cows for lowly heritable (<.10 %) traits (i.e. DPR) the sires used, in successive generations, must be very highly ranked (top 5%). Furthermore, sires can have high TPI’s but they can be inferior for essential traits. (Read more: SHE AIN’T PRETTY – SHE JUST MILKS THAT WAY!)

Balancing gives you average, but it does not give the opportunity to rapidly genetically improve traits where a herd has a significant deficit. It is almost impossible to breed the exceptional if every breeding decision is based on getting an animal average for everything. Balanced Breeding is least risk breeding and does not push the already exceptional to new heights. (Read more: BREEDING FOR LONGEVITY: DON’T BELIEVE THE HYPE – IT’S MORE THAN JUST HIGH TYPE)

Today’s Scenario and Tomorrow’s Needs

As a result of what has been achieved through Balanced Breeding, milk producers consider udders, legs, milk and component yields and somatic cell counts to be at very acceptable levels. BUT not so for the genetic levels for fertility, animal health, disease resistance, mobility and length of herd life. In fact, they have deteriorated over the past two decades. Today 30+% of the differences between herds for herd profit can be attributed to these lowly heritable traits.

Read any milk producer discussion blog and you will see their concerns about the genetic fall back for conception, for cows’ and heifers’ ability to resist production limiting diseases, for cows to breed back by 100 DIM, for cows to remain in the herd into their 4^th+ lactation, for females that calve easily, for heifers that calve by 22 months of age and the list goes on.

Sires that can produce daughters that have the genetic ability to remain in a herd to complete their fourth lactations will increase their daughters’ lifetime profit by 33%. That is significant! (US$2,500) In US Holsteins that can be achieved by using sires that are 8.0 or higher for PL. In Jerseys the best PL sires are 6.0 or greater for PL. In Canadian terms it means using sires that are 110 or greater for HL.

So Why Not Make It Simple? Select for High PL or HL!

Could it be as simple as using sires that rank relatively high for NM$, CM$ or Pro$ and which leave long-lived daughters? If a cow does not have good yield, functional type, good fertility, an ability to stay healthy and transition easily, she will not remain in the herd for four or more lactations.

Expressed another way – is the ability to produce for many lactation (high PL or HL) the most important trait that milk producers need to select for?

Total merit indexes are excellent tools for ranking sires according to breed society improvement strategies (i.e. TPI, JPI, LPI, PTAT or CONF) or populations outcome strategies (i.e. NM$, FM$, CM$, GM$ or Pro$) but bottom line focused milk producers need to dig deeper and find sires that will produce daughters that have the genetic ability to last an extra lactation above the herd average.

Which Are Some of the High PL Sires?

The Bullvine brings the following sires to milk producers attention. The sires in the tables below have very high PL’s or HL’s and they are positively genetically indexed for NM$ or Pro$, SCS, DPR or DF and DCE or DCA. It is quite unlikely that milk producers have ever read about the majority of these sires in a magazine ad or have ever considered using most of them.

Milk producers that milk other breeds can find top PL or HL sires for their breed by going to CDCB or CDN websites.

The Bullvine Bottom Line

It is important to recognize that progressive breeders always know that if you keep asking questions — including “Is this still relevant? – That you will find better answers! Total merit index, at best, places 10-15% emphasis on PL or HL. Yet, the analysis of on-farm financial records shows that the most successful milk producers place 30-35% emphasis on length of herd life when it comes to sire selection. No breeder aims to be average. Balancing all traits to get an average cow will not lead to exceptional genetic and performance results.
