Research reveals that cattle form strong social bonds whose disruption causes measurable stress, with implications for how we manage cattle groups.
The scientific evidence for cattle social bonds is compelling and has significant implications for management practices that routinely separate bonded individuals. Dairy cows maintain preferred spatial associations with particular herdmates, and separation from these partners causes measurable physiological stress equivalent to that caused by other recognized stressors. Calf separation from mothers is perhaps the most acute example — both animals vocalize extensively and show reduced feeding and exploration for days following separation. Management approaches that minimize separation events, maintain stable social groups, and allow partial social contact following unavoidable separations can reduce the welfare costs while achieving necessary management objectives.
