In 2003, Matt Steiner called into a Wisconsin sale barn and bid $8,100 on a cow the room had already written off. Wesswood-HC Rudy Missy EX-92 went on to reshape Holstein genetics for two decades. But the same genomic engine that made Missy a global brood cow was quietly dragging 198 fertility genes and 67 immunity genes in the wrong direction — and nobody caught it for 20 years. This episode unpacks where the same pattern is building right now, what it's costing you per cow, and exactly what to do before your next mating run.

KEY TAKEAWAYS

  • How genomic selection doubled genetic gain but simultaneously eroded fertility, immunity, and heat tolerance through genetic hitchhiking — and why no one noticed until billions in damage was done.
  • The barn math most producers haven't run: why the $5,070 in extra annual ...
