Inbreeding in the global Holstein population has quietly accelerated - and the financial impact often goes unnoticed. Genomic inbreeding has tripled in just ten years, causing hidden losses of $200 to $400 per cow through reduced fertility, weaker health, and shorter productive lifespans. This episode examines why these costs remain largely invisible in herd accounting, what long-term research says about the profit potential of crossbreeding, and how purebred herds can still reduce risk through strategic outcrossing and international genetics. A deep dive into why genetic decisions are…
