Cattle form lasting social bonds and experience distress when separated from companions, with important implications for herd management and welfare.
Cattle are socially sophisticated animals whose wellbeing depends substantially on stable social relationships. Frequent regrouping as animals move through production systems — from calf groups to growing groups to adult herds — disrupts established social bonds and causes aggression, stress, and welfare harm at each transition. Management systems that maintain stable social groups through production phases and minimize unnecessary regrouping events produce better welfare outcomes and often better productivity.
