The separation of calves from their mothers shortly after birth is one of the most contentious welfare issues in dairy farming.
Immediate mother-calf separation, standard in conventional dairy, causes acute stress for both animals. Research shows calves benefit substantially from extended contact with their mothers: improved immunity through better colostrum intake, reduced stress hormones, and better long-term behavioral development. Partial suckling systems, where calves nurse twice daily while surplus milk is collected, represent a practical middle ground that significantly improves welfare outcomes.
