Standard dairy industry practice separates calves from their mothers within hours of birth. Research reveals significant welfare costs for both mother and calf from this early separation.
Early mother-calf separation causes measurable and significant welfare harm. Cows vocalize persistently after separation, showing behavioural indicators of grief and stress. Cortisol levels remain elevated for weeks. Calves separated early show impaired social development, increased susceptibility to disease, and higher stress reactivity throughout life. The natural bond between cow and calf is strong; wild and feral cattle nurse their young for many months. Suckling also provides important immune benefits through colostrum. Alternative systems where calves remain with mothers for extended periods or are kept in small groups demonstrably improve welfare outcomes.
