Dairy calves are separated from their mothers within hours of birth in most commercial operations, causing acute distress for both the calf and the cow.
Early maternal separation is one of the most ethically troubling practices in dairy farming. Both cow and calf show clear behavioral and physiological signs of distress — vocalizations, reduced feeding, elevated cortisol — that persist for days. Extended contact systems, where calf and cow share time for weeks, significantly reduce acute distress, but represent a small fraction of global dairy production. Male calf welfare is a systemic issue with few current solutions.
