The treatment of dairy calves from birth through weaning is one of the most welfare-contested areas of dairy production, with separation practices receiving particular scrutiny.
Calf-cow separation at birth causes documented acute distress - sustained vocalization, pacing, and disrupted suckling behavior in both cow and calf. The practice is driven by milk production economics and disease prevention but conflicts with strong maternal behaviors in both species. Extended contact systems show that some degree of cow-calf contact is compatible with dairy production, though requiring management adjustment. Progressive dairy farms are demonstrating that calf welfare can improve without abandoning dairy production.
