Cattle are highly social animals whose complex social behaviours have profound implications for housing and welfare.
Cattle social complexity is frequently underestimated in housing system design. The assumption that any cow with other cows is socially satisfied is wrong — cattle have preferences, relationships, and stress responses to social disruption that have measurable welfare and production impacts. Regular regrouping in commercial systems is a significant welfare stress. Housing systems that maintain stable social groups, allow choice in social contact, and provide enough space to avoid forced proximity improve welfare substantially.
