The reproductive cycle of dairy cows involves repeated pregnancies, mother-calf separation, and male calf disposal practices that raise serious welfare concerns.
The welfare costs of the dairy reproductive cycle are substantial and occur at every stage. Artificial insemination, while generally safe, involves physical manipulation that some cows find aversive. The early separation of cow and calf is the most visible and emotionally salient welfare concern: mother cows frequently call for their calves for days after separation, and calves show elevated stress hormones and reduced feeding behaviour. Extended contact systems, where calves remain with or have daily contact with mothers for several weeks, significantly reduce separation distress. Male calf welfare has improved in the UK as demand for dairy veal and rose beef has grown, reducing the number shot at birth. But the fundamental structure of dairy - constant pregnancy and lactation for shortened lives - remains a deep welfare concern.
