Weaning in beef and dairy cattle causes acute stress in both cows and calves, and management strategies that reduce this transition's impact are important welfare improvements.
Weaning causes measurable acute stress in both beef calves and their mothers. Abrupt, complete separation is the most stressful approach. Two-stage weaning methods - first separating nutritionally while maintaining social contact, then separating completely - significantly reduce the behavioural and physiological stress response. In dairy systems, extended calf contact before weaning reduces separation distress.
