How the separation of dairy calves from their mothers causes distress and what more humane dairy systems look like.
Early separation of dairy calves from their mothers is one of the most widely criticised practices in conventional dairy production. The bond between a cow and her calf forms within hours of birth, and the mutual distress of separation is measurable, prolonged, and clearly significant. The cow calls for her calf for days; the calf is isolated and stressed, with elevated cortisol and reduced feed intake. This welfare cost has historically been accepted as the practical requirement of dairy production, but research and practice have demonstrated that prolonged suckling systems, where calves remain with cows for weeks to months, can be integrated into commercial dairy operations without prohibitive production losses. The welfare case for extended contact is strong, and consumer demand is beginning to drive adoption.
