Dairy cows are highly social animals with complex relationships, and modern farm management that disrupts social bonds causes measurable welfare harm.
The social complexity of cattle is frequently underestimated. Dairy cows form long-term bonds, preferring to spend time with certain individuals and avoiding others. They respond to the distress of herd mates and show reduced productivity and immune function when repeatedly subjected to social disruption from group changes. The standard practice of separating calves from mothers within hours of birth causes distress responses that persist for days. Prolonged calf-cow contact systems are being trialed with positive welfare outcomes, though they create management challenges in conventional production.
