Early calf separation from dams within 24 hours causes acute distress to both cow and calf; dam-rearing and extended contact alternatives offer welfare improvements.
Early separation of cow and calf is one of the most welfare-significant practices in dairy farming. The distress of both animals is audible and physiological - cortisol elevation, weight loss in separated calves, and prolonged vocalization reflect genuine suffering. Extended contact systems demonstrate that welfare improvement and dairy production can coexist, though commercial scaling remains challenging.
