In this episode of The Moos Room, Brad revisits a large Minnesota-based study exploring the true cost of health events in dairy cows—and why tracking cost, not just disease incidence, could transform genetic selection and farm profitability.Using data from thousands of Holstein cows across multiple herds, the team found that health costs are heavily concentrated in the first 30 days of lactation, when cows face metabolic stress from calving and high milk production. However, issues like lameness and mastitis continue to accumulate costs throughout the lactation, especially in older cows. In fact, total health costs more than double from first to later lactations, reflecting wear, immune fatigue, and management differences.A key takeaway: management determines cost, but genetics influence risk. While some high-cost conditions (like reproductive disorders) are difficult to improve genetically, others—such as mastitis and metabolic disease—show stronger heritability.The breakthrough insight is that total health cost itself is moderately heritable (~0.25)—much higher than traditional “sick vs. not sick” measures. This means selecting animals based on overall health cost could drive faster genetic progress than current methods.Brad also highlights important genetic and phenotypic relationships: Higher milk production is linked to increased health costs  Lower somatic cell count strongly reduces total health costs  Taller, more angular cows tend to have higher health costs  Shallower udders are associated with better health outcomes From a practical standpoint, the episode emphasizes: The need for consistent, detailed health and cost recording Moving beyond binary disease tracking to full economic impact Incorporating total health cost into sire selection decisionsBottom line: Selecting for lower total health cost can improve profitability, extend cow longevity, and enhance animal...","thumbnail_url":"https://img.transistorcdn.com/EIqekZJUCM-mbRXSkEsLe4I4Erj3AsT3id_xoW-dk6k/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzE0MTkwLzE2OTc0/ODIyODEtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
