The separation of dairy calves from their mothers at or shortly after birth is one of the most significant welfare concerns in conventional dairy production, affecting millions of animals annually.
Early separation causes acute distress in both cow and calf, who vocalize, pace, and search for each other for days after separation. Calves denied maternal nursing lose access to immune-boosting colostrum through natural nursing and the behavioral enrichment that suckling provides. The routine nature of this distress across the global dairy industry represents a massive source of animal suffering that remains largely invisible to consumers.
