Cattle are highly social animals with complex dominance hierarchies and social bonds whose disruption causes significant welfare harms in commercial production systems.
Cattle social complexity is routinely disrupted in commercial farming systems through mixing, separation and transport. Each disruption to established social groups triggers dominance fighting, stress hormones and welfare costs. The standard practice of mixing cattle at housing, during fattening and at transport means many farm cattle live in states of near-constant social disruption. Managing cattle in stable social groups from birth to slaughter — with careful mixing protocols when unavoidable — reduces this welfare harm substantially. The economic benefits of better welfare through reduced injury and improved growth justify investment in stable group management.
