Social management in beef cattle feedlots — including group stability, stocking density, and feeding space — significantly affects welfare through effects on aggression, stress, and access to resources.
Social welfare in feedlot cattle is determined by group composition decisions, stocking density, and resource availability. Cattle mixed from multiple farms at feedlot entry face simultaneous transport stress and social aggression that creates a combined welfare burden in the first weeks. Subordinate animals in resource-limited pens experience chronic low-level stress from competition access failures. Management practices that minimize mixing, provide adequate linear feeding space per animal, and design pens to allow subordinate escape routes reduce the social welfare cost of group housing at commercial scale. These changes are achievable within existing production models with modest management investment.
