The Bullvine Podcast breaks down the inbreeding tax: roughly $44 per cow for every 1% over baseline in lifetime drag, plus $60 to $100 per cow, per lactation in the herds carrying the most. Net Merit and TPI don't penalize it — that math lives entirely in your matings. We cover why it's happening, and the one linear rule that separates real dairy strength from expensive frailty. What You'll Learn Why 99.84% of active Holstein AI bulls trace back to just two 1960s grandfathers How a 5-point inbreeding jump costs a cow 92 kg milk and 65 days of productive life The 1:1 Frame Rule — if Stature STA beats Strength STA, you're buying height, not cow Why your index won't manage inbreeding, and what actually does The 3-step audit to run before your next semen order Inbreeding depression doesn't send an invoice — it shows up as the cow that won't settle, the calf that never thrives, the good one that leaves early. At 9.99% and climbing roughly three times faster in the genomic era, the drift compounds silently. This episode turns it into barn math you can act on: know your herd number, set a mating ceiling, and check strength against stature before you order.
