The separation of dairy calves from their mothers within hours of birth is standard practice globally, causing acute distress for both cow and calf.
Early separation prevents bonding and causes acute distress measured in sustained vocalisation, reduced feeding, and elevated stress hormones in both cow and calf. Calves separated immediately have higher disease rates than those allowed extended maternal contact. The rationale for immediate separation is disease prevention and milk availability, but research shows these objectives can be achieved while allowing greater maternal contact. Extended contact systems require careful management but deliver better welfare outcomes.
