Separating dairy calves from cows within hours of birth causes acute distress for both — extended cow-calf contact systems improve welfare while maintaining milk production viability.
Cow-calf separation causes an acute grief-like response in both animals, with vocalisation, reduced feed intake, and elevated cortisol persisting for days. The welfare cost is among the most significant in dairy production. Extended contact systems show calves can be weaned at 8-12 weeks with lower distress. Some progressive farms now offer mother-reared milk as a premium product.
