Cover Story: Improving the sustainability of beef cows involves reducing feed costs and enteric methane emissions and increasing calf production while addressing concerns including animal health and welfare and worker safety. Reducing cow weight can favorably impact feed costs and methane emissions. Cumulative weight weaned observed throughout a cow’s productive life directly addresses calf production and indirectly addresses other concerns—cumulative production is higher for cows who wean healthy calves and avoid culling because of reproductive failure, unsoundness, and dangerous behavior. This examination of cow weight and cumulative weight weaned in a herd of crossbred cattle suggests cow weight can be controlled by selection, but mating strategies to maximize heterosis or reduce genomic inbreeding are needed to breed for increased productivity.
