What if the secret to healthier, longer-living, and more profitable cows isn’t about chasing the highest single genetic index, but plugging the gaps left by old-school selection? In this episode, we challenge dairy’s “one-number” mindset and dive headfirst into the “No-Holes Sire” approach—a bold, research-backed strategy that’s redefining how progressive farmers, AI studs, and herd advisors breed for tomorrow’s bottom line. Expect tough questions, revealing data, and practical steps you won’t find in the average breed publication.

Key Takeaways:

• Discover why single-trait and traditional total merit selection may be ruining long-term herd viability and farm profitability.
• Learn about Lactanet’s new six subindex framework and why it’s a game-changer for balanced genetic progress.
• Find out how using sires with at least 5 of 6 subindexes above the 50th percentile can increase herd life by up to 15% and net profit per cow by hundreds of dollars.
• Uncover irrefutable global research showing each €1 gained in balanced genetic index yields nearly €2 in actual net profit per cow.
• Get step-by-step advice on implementing the “No-Holes Sire” strategy on your farm, including what metrics to track and which pitfalls to avoid.
• Hear a critical discussion on breedings' future: Will no-holes genetics become the new industry norm, or are you risking herd health by sticking with familiar names?

This episode pulls no punches, exposing the shortcomings of legacy genetic selection and putting today’s profit challenges into sharp focus. We break down the hard numbers behind the “No-Holes Sire” philosophy, with data not just from Canada, but across Ireland, the US, and Europe—showing how balanced selection outperforms one-dimensional index chasing on every level that matters: fertility, health, longevity, and cashflow. Listeners will explore Lactanet’s cutting-edge six-part subindex system and see real-world case studies of herds that have slashed lameness incidents, cut open days, and extended cow lifespans—all while improving margins, not just genetic charts. If herd health costs, feed prices, and replacement rates keep you up at night, this episode will arm you with actionable steps to future-proof your operation. Learn how to audit current sire choices, set breed goals aligned with your market reality, and stay ahead of the competition by embracing the genetic principles transforming top-performing dairies in 2025. Whether you’re a data-driven geneticist, a hands-on herd manager, or advising the next generation, these insights could change your ROI for years to come.
