This episode builds on a technical article addressing the growing level of inbreeding in Holstein breeding programs and its economic implications. It examines how the dominance of a limited number of sires, largely driven by major artificial insemination companies, has narrowed the genetic base and pushed inbreeding rates close to ten percent. The resulting decline in milk yield, fertility, and overall robustness directly affects herd profitability. The podcast discusses the strategic response of independent breeders who prioritize deeper cow families, functional traits, and broader genetic…
