Incorporating welfare-relevant traits into cattle breeding selection indices improves herd health outcomes across generations.
Genetic selection decisions made today affect the welfare of thousands of cattle over generations. Selection that prioritizes production traits while ignoring disease resistance and longevity creates cattle that are physiologically pushed beyond sustainable limits. Incorporating lameness resistance, mastitis resistance, and longevity into selection decisions reduces the welfare burden of common diseases across entire herds. The genetic tools to make welfare-informed selection decisions are increasingly available - using them is a long-term welfare investment.
