On Herd Health, Dr. Brad White and Dr. Bob Larson discuss a 2025 study in the Canadian Journal of Animal Science on factors influencing heifer replacement and cow-calf profitability. The study focused on cow feed efficiency, longevity, heterosis, and lifetime productivity. Key findings include the importance of longevity, with heifers staying longer in the herd being more profitable. Crossbreeding, particularly those with more heterosis, reduced costs. Residual feed intake (RFI) was crucial, with lower RFI cows being more efficient and cost-effective. The study used data from 2011 to 2018, accounting for economic fluctuations, and found no significant differences between breeds.
