The routine separation of dairy calves from their mothers within hours of birth is one of the most debated welfare practices in modern dairy production.
Early maternal separation causes acute grief responses in both cow and calf. Cows search and call for calves for days; calves show elevated cortisol, reduced feeding, and social withdrawal. The bond formed in even the first hours of life is hormonally reinforced and emotionally significant. Delaying separation or allowing partial contact meaningfully reduces distress indicators, and emerging research shows positive effects on long-term calf resilience and productivity.
