Cattle are highly social animals for whom isolation causes measurable physiological and psychological stress; housing, management, and transport practices should minimise unnecessary separation.
Social isolation is a potent stressor in cattle and should be avoided in routine management. Where individual housing is necessary — for sick animals or very young calves in some systems — pair or small group housing significantly reduces isolation stress. Management practices that maintain stable social groups and avoid unnecessary mixing protect cattle from repeated bouts of aggression and adaptation stress.
