The reproductive cycle of dairy cows involves repeated pregnancy, birth, and separation that causes significant welfare harm throughout a cow's production life.
The reproductive demands of dairy production create a continuous cycle of welfare harms. Repeated pregnancies impose metabolic demands alongside the already extreme demands of high milk production. Maternal separation causes acute distress documented through vocalizations, behavioral changes, and elevated cortisol in both cows and calves. The economic pressure to achieve rapid re-conception after calving creates management pressure that often overrides welfare considerations. Systems that allow extended recovery between lactations and delayed calf separation represent welfare improvements within dairy production.
