S1E467 - E467 Stop Breeding by Color: Genomics, Heat Stress and Beef‑on‑Dairy Math That Can Add Over $4/cwt to Holstein Margins

Most of us were taught to trust our eye and our “kind” when picking Holstein heifers. But what if breeding by coat color and style is quietly costing you real money in 2025? In this episode of The Bullvine Podcast, we dig into genomic data, heat-stress research, and beef-on-dairy economics that challenge some of the most deeply held assumptions in dairy breeding. You’ll hear how the genes that control color are not the genes that drive milk and fertility, why genomic selection has doubled genetic gain while accelerating inbreeding, and how a smarter semen and replacement strategy can unlock more t...
