Pig Welfare and Social Complexity

Pigs live in complex social groups with hierarchies, alliances, and individual relationships that welfare systems must accommodate.

Key Facts

Wild and feral pigs live in social groups of related females with overlapping ranges
Commercial housing disrupts natural social structures through mixing and regrouping
Stable social groups with familiar individuals show lower aggression and higher positive social behavior
Individual recognition of social partners is important for pig social navigation
Social enrichment through stable groups and visual barriers reduces competition and aggression

Welfare Considerations

Pig social complexity is a welfare resource and a welfare challenge simultaneously - pigs that can form stable relationships experience positive social bonds, but disrupted groups experience the stress of constant social conflict. Stable group management respects and utilizes natural pig social structure.
