Pig Pen Design Aggression Management

Pen design that reduces opportunities for sustained aggression significantly improves pig welfare. Research-informed design principles minimize aggression injuries.

Key Facts

Solid barriers enable escape from aggression without pen exit
Multiple feeding and drinking points reduce competition bottlenecks
Increased space allowance reduces aggression frequency and severity
Visual barriers allow social avoidance without physical separation
Pen shape affects ability to corner and mob subordinate pigs

Welfare Considerations

Pigs unable to escape sustained aggression in simple pen designs suffer injury and chronic stress from repeated attacks. Pen design that provides visual barriers, escape routes, and distributed resources enables subordinate animals to avoid dominant aggressors. These design features reduce both the frequency and severity of aggression-related welfare harm.
