The separation of calves from dairy cows at birth is a major welfare issue with physical and psychological consequences.
Early maternal separation causes acute distress responses in both cows and calves that are measurable in stress hormones, vocalization patterns, and behavior. Calves separated early show higher rates of illness, reduced growth, and behavioral abnormalities. Cows pacing and calling for days after separation exhibit clear signs of grief. Extended suckling systems where calves remain with mothers longer show improved welfare indicators for both. The veal industry compounds welfare problems for male calves through restrictive housing and iron-deficient diets.
