Farmed Pig Pen Design Aggression Reduction

Specific pen design features significantly reduce aggression and injuries in group-housed pigs, demonstrating that housing design is a welfare intervention.

Key Facts

Welfare Considerations

Pen design choices directly determine the frequency of aggressive encounters and injuries in pig groups. Well-designed pens that allow subordinate animals to avoid dominants and reduce resource competition create calmer, less injurious social environments. The welfare investment in good pen design pays off through reduced medication costs, better growth rates, and fewer injury-related deaths.
