Dairy cows are maintained in near-continuous pregnancy and lactation cycles, raising welfare concerns about reproductive stress, calf separation, and breeding-related health issues.
The reproductive cycle of dairy cows imposes significant welfare costs at multiple points. The bond between cow and calf is disrupted by early separation, causing acute distress to both animals. High milk yields have been selected at the expense of reproductive efficiency, meaning many cows experience failed pregnancies. Extended lactation programmes that reduce calving frequency and permit longer cow-calf contact represent meaningful welfare improvements within commercial dairy systems.
