Dairy calves are typically separated from their mothers within hours of birth, causing distress to both cow and calf. Extended suckling programs offer welfare improvements that are gaining commercial traction.
Maternal separation causes acute distress that is measurable in both cow and calf vocalization rates, cortisol, and behavioral indicators. Cow-calf contact systems that allow nursing while managing biosecurity challenges reduce this distress while improving calf development. Gradual weaning over days to weeks is less stressful than abrupt separation. Consumer willingness to pay for contact dairy products is creating market incentives for this welfare improvement.
