Reproductive management in dairy herds depends on accurate estrus detection, but failures cause repeated pregnancy attempts, extended open periods, and welfare costs that accumulate across the herd.
Reproductive welfare in dairy cows encompasses the experience of estrus itself, the handling and procedures involved in artificial insemination, and the downstream consequences of reproductive failure. Estrus is a physiological state accompanied by restlessness, increased walking, and social behaviour — behaviours that are difficult to express on concrete surfaces or in restricted housing. Repeated rectal palpations for pregnancy diagnosis cause measurable stress responses; ultrasound-guided procedures minimise tissue trauma. Failed reproduction leads to prolonged treatment cycles and eventually culling — often before cows have completed their productive life. Welfare-conscious herds use validated automated detection systems, minimise unnecessary handling, and make culling decisions that account for individual cow history and prognosis rather than purely economic throughput criteria.
