The catalogs are full of top‑10 sires from the same bloodlines. Dann Brady and ferme Blondin couldn’t find the pedigrees they wanted – so they built the stud they couldn’t buy from.

Dann Brady, co-founder of Blondin Sires, St. Placide, Quebec. When the big AI catalogs couldn’t deliver the cow families he wanted, Brady and his partners started their own stud under code 799.
Dann Brady had a specific problem. The General Manager and Co-Founder of Blondin Sires in St. Placide, Quebec, wanted bulls backed by deep, documented cow families — sires where you could trace maternal longevity and functional type back through generations of real milk records, not just index printouts. He went looking through the major AI catalogs. What he found were rank leaders from the same tight circle of bloodlines everyone else was already using. What he couldn’t find were the pedigrees behind them.

“Over the past few years, the rush of genetics has overshadowed the true art of breeding great cows,” Brady and his partners wrote when they launched Blondin Sires. “We decided it was time to put the emphasis back on great type and deep pedigrees combined with production, health & fertility”. And in an interview, Brady laid it out plainly: “We have a focus on type and pedigree combined with using genomics and the show ring to market and promote our breeding. Breeding for long lasting, high producing, deep pedigreed cows”.

So Brady and his partners — Simon Lalande and the team at ferme Blondin — started their own stud under code 799. It wasn’t a vanity project. Blondin began releasing young sires as early as 11 months of age, months ahead of the industry standard of 15–18 months, built a sales team of 25 across Canada, and grew its share of Canadian sire usage from 2.8% in 2022 to 4.9% in 2023, according to Lactanet market data. That’s a 75% jump in a single year, built without a global distribution network or a corporate parent.
Across Ontario, the Stanton Brothers made a parallel bet from their dairy operation, marketing genetics directly to producers. Their bull Remover PP reclaimed the #1 spot on Canada’s Proven Holstein LPI rankings in August 2025 at +3897 — backed by 234 daughters across 32 herds — the first homozygous polled bull to top a major national index based on daughter performance. No major study had bothered to build a whole program around that niche.
These operations aren’t outliers. They’re businesses growing into structural gaps the biggest genetics companies created—and largely can’t fill.

Two Bulls and More Than 99% of the Gene Pool
A number that deserves to land differently than it usually does: more than 99% of North American Holstein AI sires trace their paternal lineage to just two bulls — Pawnee Farm Arlinda Chief and Round Oak Rag Apple Elevation, both born in the 1960s. Penn State geneticist Chad Dechow’s research documented this through Y-chromosome analysis: Chief accounts for roughly 49% and Elevation for 51% of active AI sire lines, with only a fraction of a percent from any other lineage (Yue et al., 2015). Every other Y-chromosome line that existed at the start of artificial insemination has effectively gone extinct in commercial use.
The consolidation behind that bottleneck accelerated fast. Three major entities — URUS (formed from the Alta/GENEX/Trans Ova mergers), Select Sires (in the process of merging with STgenetics’ production arm), and Genus PLC (parent of ABS Global, selling into around 80 countries) — control the vast majority of elite Holstein genetics moving through North American herds. The number of Holstein bulls actively sampled through AI dropped roughly 61% between 2010 and 2020, per Bullvine analysis.
Genomic selection drove real genetic progress during that same period — research estimates that gains increased by 50% to 100% for yield traits. But it also compressed generation intervals dramatically, from roughly five years to as little as two on the fastest pathways, through genomic testing and juvenile IVF technologies. The gains are genuine. So is the narrowing.
What Does Rising Inbreeding Actually Cost Per Cow?
Lactanet Canada’s August 2025 update puts the average inbreeding level for Holstein heifers born in 2024 at 9.99% — nearly double what it was fifteen years ago. John Cole, a USDA geneticist, walked through this acceleration in detail at the 2024 Beef Improvement Federation symposium, and the rate of change caught even some industry veterans off guard. Dr. Chad Dechow at Penn State reports that current Holstein inbreeding levels in the US average around 8%, with young bulls running somewhat higher at 9–10%. When researchers measure inbreeding genomically — through actual runs of homozygosity in the DNA — the numbers come in higher still. Italian Holstein data from Ablondi et al. (2023) at the University of Parma showed a mean genomic inbreeding (FROH) of 16% across 27,735 cows in 939 herds.
| Year | Avg Inbreeding (%) |
|---|---|
| 2009 | 5.1 |
| 2012 | 6.2 |
| 2015 | 7.4 |
| 2018 | 8.5 |
| 2021 | 9.2 |
| 2024 | 9.99 |
And here’s what it costs. Ablondi et al. found every 1% increase in genomic inbreeding cut 305-day milk yield by 61 kg. Using pedigree-based inbreeding, the loss was 44 kg per 1% increase in inbreeding. Doekes et al. (2019), working with Dutch Holstein–Friesians at Wageningen University, reported about 36 kg of milk per 1% increase in pedigree inbreeding, plus a half-day longer calving interval and higher somatic cell scores.

Run the math on your own herd. Research from Virginia Tech found that each 1% increase in inbreeding costs approximately $22–$24 per cow in lifetime profit — and that’s in 1999 dollars. Adjusted for inflation, that’s roughly $40–$43 today. On a herd averaging 10% inbreeding, the accumulated drag works out to $400–$430 per cow over a lifetime. Nobody sends you an invoice for that. It just… shows up. Slightly worse conception rates. A few extra mastitis treatments. Heifers that leave before the third lactation. Your records say “bad luck.” The math says otherwise.
| Inbreeding Level | Milk Loss per Lactation (kg) | Calving Interval Increase (days) | Lifetime Profit Loss per Cow (CAD) | Total Herd Cost (200 cows, CAD) |
|---|---|---|---|---|
| 6% | 366 kg | 3 days | $240–$260 | $48,000–$52,000 |
| 8% | 488 kg | 4 days | $320–$344 | $64,000–$68,800 |
| 10% | 610 kg | 5 days | $400–$430 | $80,000–$86,000 |
| 12% | 732 kg | 6 days | $480–$516 | $96,000–$103,200 |
Why the Big Catalogs Can’t Fix What They Created
Brady’s frustration pointed to something structural — not bad intentions, but gaps that stem from how consolidated AI companies make money.
Major studs routinely hold back their highest-ranking young sires for internal nucleus use before releasing semen broadly. Many companies have restricted access to young sires both because of limited semen production and to maintain competitive leadership. By the time a top genomic bull reaches your tank, his sons may already be entering the pipeline. Blondin and Stanton positioned against this directly: no restrictions, every bull available to every customer.

Corporate catalogs sell index numbers. The dam’s lifetime production, the granddam’s longevity record, the maternal line’s functional depth — that context has largely vanished from mainstream AI marketing. Brady and his partners founded Blondin specifically because they wanted that cow-family transparency and couldn’t buy it. And if a sire doesn’t project into the top tier for TPI or NM$, he rarely gets a catalog slot at a major stud. Rational for a company optimizing revenue per straw across a global network. But it means genuinely outcross bulls from distinct pedigree backgrounds get cut before producers ever see them.
The breeder economics shifted, too. The Bullvine documented in January 2026 that a well-run seedstock operation that generated $1.5 million in genetics revenue a decade ago might bring in $150,000 today — with objectively better cows. Corporate contracts now transfer semen rights, lock in female purchase options, and grant perpetual data licenses. Breeders like Brady looked at that landscape and saw a different kind of opportunity: own the bull, own the semen, control the marketing, and capture the upside yourself through facilities like DMV GenetiQ Services in Drummondville, Quebec. DMV’s model is straightforward — the breeder pays for boarding, health tests, and semen collection and freezing, but keeps 100% of the product and retains decision-making authority. The operation recently expanded to house 130 bulls and store 500,000 doses of semen, with four veterinarians on staff. Blondin bought a stake in DMV in 2022 to lock in that infrastructure for its growing bull lineup.
What the Europeans Figured Out Decades Ago
VikingGenetics and CRV didn’t stumble into genetic diversity. They engineered it.

Viking’s Nordic Total Merit index included mastitis resistance starting in the 1980s and general health traits by 1987, decades before North American indexes seriously weighted health. Today, health, reproduction, and longevity carry 45% of NTM’s total weight, per VikingGenetics — the highest ratio among major total merit indexes globally. NTM combines 90 different sub-indices into 15 main traits, drawing from a population in which Nordic cows are recorded for health traits through data from vets, hoof trimmers, and slaughter plants, all compiled into a single database. Their current top genomic VikingHolstein, VH Sandro (VH Skills × Youngster), carries a gNTM of +38 and projects daughters at 12,289 kg milk, 4.24% fat, and 3.54% protein — with an average 963 days in production. That’s the kind of profile that comes from selecting on functional longevity, not just peak yield.
CRV in the Netherlands runs a similarly deliberate funnel through its Delta breeding program. Starting from around 12,000 embryos produced each year, CRV genomically tests approximately 3,000 male calves and ultimately selects around 60 for semen production — drawing intentionally from 40 different black-and-white sires of sons and 20 red-and-white to maintain population diversity. “To maintain and ensure sufficient variation in the paternal bloodlines, we use around 40 different black-and-white bulls,” CRV’s head of product development, Jaap Veldhuisen, explained. On the health side, their bull Delta Boyan (Warren P RF × Endless RF) scores +19% CRV Efficiency and +6% CRV Health, with a 112 udder health and 111 hoof health breeding value — the kind of multi-trait health profile that North American rankings don’t yet fully capture. Both organizations are farmer cooperatives. Their shareholders milk the daughters. That makes it commercially viable to trade a few points of short-term index for long-term population health.
For North American producers, Viking and CRV bulls function as ready-made outcross tools with health-heavy proof profiles and genuine pedigree distance. But telling a real outcross from a Holstein with a European postal code takes homework. If you can read three generations of pedigree and recognize every sire name from your current AI catalog, it’s probably not the diversity you’re looking for. Screen instead for bulls with strong simultaneous scores across udder health, daughter fertility, and longevity — a CRV Health score above +5% or a NTM health sub-index well above breed average — combined with sire stacks you don’t already have in your tank.
| Breeding Program / Index | Health/Fertility/Longevity Weight (% of Total Merit) | Key Traits Measured | Example Bull Profile |
|---|---|---|---|
| VikingGenetics (NTM) | 45% | Mastitis resistance, general health, daughter fertility, herdlife, calving traits | VH Sandro: +38 gNTM, 12,289 kg milk, 963 days in production |
| CRV (Delta Program) | 40% | Udder health, hoof health, daughter fertility, calving ease, longevity | Delta Boyan: +19% Efficiency, +6% Health, 112 udder health BV |
| North American TPI | 25–30% | Productive life, SCS, daughter pregnancy rate, calving ease | Focus historically on production and type |
| North American NM$ | 28–33% | Productive life, SCS, livability, daughter pregnancy rate | Economic weighting includes health as cost driver |
Is Your Mating Plan Building an Asset — or Slowly Borrowing Against Your Daughters’ Future?
Research consistently shows that recent inbreeding — long runs of homozygosity in the genome — hits harder than older, more distant inbreeding. Ablondi et al. (2023) found that longer ROH segments (over 8 Mb, reflecting recent common ancestors) had a significantly negative effect on all production traits, while shorter segments were less consistent. Doekes et al. (2019) confirmed the pattern in Dutch Holsteins. Line-breeding on the latest popular bloodline does more damage per percentage point than having common ancestors five or six generations back.
And the University of Minnesota’s 10-year ProCROSS study shows what pushing back looks like in practice. Three-breed crossbred cows (Holstein × VikingRed × Montbéliarde) showed up to 15–20 fewer days open, first-service conception rates up to 9–10 percentage points higher in second and third lactations, and herdlife 147 days longer than purebred Holsteins. Daily fat-plus-protein production for lifetimes of those three-breed crossbreds was 1% lower than their Holstein herdmates, while two-breed crosses were actually 1% higher. Professor Les Hansen at the University of Minnesota led the research across herds averaging 13,587 kg of milk, 512 kg of fat, and 426 kg of protein. Daily profits for ProCROSS cows ran 9–13% greater than purebred Holsteins.

| Performance Metric | Pure Holstein | Two-Breed Cross | Three-Breed ProCROSS | ProCROSS Advantage |
|---|---|---|---|---|
| Days Open | Baseline | 15 fewer | 15–20 fewer | Fertility recovery |
| First-Service Conception (2nd/3rd lactation) | Baseline | +7–8% | +9–10% | Heterosis payback |
| Herdlife (days) | Baseline | +85 days | +147 days | 5 more months productive |
| Daily Fat + Protein (kg) | Baseline | +1% | -1% | Minimal production trade-off |
| Daily Profit per Cow | Baseline | +10–12% | +9–13% | $0.90–$1.30 per cow per day |
That isn’t a theoretical model. It’s a decade of measured data from high-production herds. And while most operations won’t go full crossbred, the ProCROSS results quantify what happens when you deliberately invest in genetic diversity: the traits most damaged by inbreeding — fertility, health, survival — are exactly the ones that recover.
Four Ways to Hedge Your Genetics — and What Each One Costs
Keep 65–70% with your main AI supplier—but stop accepting the default. This is where most of your genetic gain, sexed semen supply, and technical support lives. Don’t unplug it. But ask your rep to show you the sire-of-sons diversity in your mating plan. If all roads trace back to the same three or four global sires, you’re stacking risk regardless of how the indexes look. Request lower-relationship sires specifically. Set hard inbreeding caps in your mating program — not just “avoid close relatives” but an explicit ceiling on expected future inbreeding per mating.
Allocate 15–20% to European cooperative genetics. VikingHolstein and CRV Holstein EU bulls offer genuine pedigree distance from the North American mainstream, bred under health-heavy total merit indexes. Target these matings at your most inbred cow families. Up to 5% of this allocation could go to a structured crossbreeding trial — VikingRed or Montbéliarde on your worst-performing, highest-inbreeding cows, where heterosis pays back fastest. The ProCROSS data shows that the fertility and survival payback is immediate, even though the daily component yield on three-breed crosses dips by about 1%. The trade-off beyond production: limited sexed-semen availability on some European sires, longer shipping lead times, and proof profiles that may not translate perfectly to your climate and management system.
What if you only have a budget for one outcross move this season? Direct 10–15% of matings to independent North American studs. Blondin, Stanton, and operations using DMV GenetiQ-style service centers offer unrestricted bull access, cow-family transparency, and niche trait programs the majors won’t prioritize. Per-straw costs will be higher than those in volume programs from the big studs — DMV GenetiQ charges breeders for boarding, health testing, collection, and freezing, with the breeder setting their own marketing and pricing. You’re paying more per unit for something the big catalog can’t deliver: pedigree distance with a story you can verify. But before writing any cheque, get clear answers: Who owns the semen and data? What health-testing standard do they follow — CSS-equivalent or not? Are the proofs from official national evaluations with published reliabilities? What’s the succession plan if the principal gets sick or sells the business? Can they actually ship sexed product to your region on a reliable schedule? Vague answers on any two of those should end the conversation.
Your 30-day action: Pull your herd’s inbreeding report from Lactanet or CDCB this week. Identify your most inbred cow families by average inbreeding coefficient. Those are the animals where your next mating decision matters most — and where a single outcross sire choice can do the most immediate good. Virginia Tech’s data gives you a baseline for that conversation with your AI rep: roughly $40–$43 per cow per 1% inbreeding in today’s dollars. On a 200-cow herd averaging 10% inbreeding, the accumulated lifetime drag is somewhere around $80,000–$86,000 across the whole herd. Even clawing back one or two percentage points on the next generation of replacements moves real money.
Key Takeaways
- This month: Pull your herd’s inbreeding report. Canadian Holsteins are rising by 0.25% per year on a pedigree basis, according to Lactanet. If your heifer cohort is above the breed average of 9.99% for 2024-born animals and trending upward, the strategies in this article aren’t optional—they’re overdue.
- Within 90 days: Ask your AI rep to walk you through the sire-of-sons diversity in your current mating plan — not just individual mating inbreeding, but the population-level picture. Request one catalog from an independent stud or European cooperative and compare pedigrees to what you’re currently using.
- Within 12 months: Compare conception rate, mastitis incidence, and first-lactation survival by sire group on any outcross or crossbred matings you’ve started. Track the heifer-class inbreeding year over year. If the trend is flattening while genetic merit holds, you’ve found your balance.
- Before buying from any independent stud: Demand clear answers on ownership and data rights, CSS-equivalent health testing, official genomic evaluations with published reliabilities, a written business continuity plan, and reliable distribution, including sexed semen capability. Vague answers on any two should end the conversation.
The Bottom Line
Dann Brady pulled up his own herd’s numbers years ago and didn’t like what he saw. He didn’t write a letter to the AI industry asking them to fix it. He started a company—and grew it 75% in a year by selling exactly what the big catalogs had stopped offering.
You don’t need to start a stud. But Brady’s question is the same one every Holstein producer should be sitting with right now: when you look at where your herd’s genetic diversity is headed over the next five to ten years, do you like what you see? And if you don’t — what changes this breeding season?
