Farm Pig: Group Penning and Enrichment Design

The physical design of pig pens profoundly influences how effectively enrichment is used and whether natural behaviour can be expressed.

Key Facts

Pen shape and size affects how evenly enrichment is distributed across the pen
Centrally located enrichment items serve more pigs than those placed in corners
Suspended chains at nose height receive more interaction than those placed too high or too low
Multiple enrichment points prevent monopolisation by dominant pigs
Enriched pens with good design show lower tail biting and aggression rates than poorly designed pens

Welfare Considerations

Good pen design is the foundation on which enrichment effectiveness is built. Even the best enrichment materials will underperform in poorly designed pens where dominant pigs control access or where the physical layout concentrates animals in ways that increase stress. Investment in pen design improvements often delivers greater welfare benefit than simply adding more enrichment material.

What You Can Do

Review enrichment placement relative to pig use and interaction rates
Ensure multiple enrichment points prevent monopolisation in group pens
Check chain and rope heights regularly as pigs grow and adjust accordingly
Design pen layout to provide retreats and visual barriers that reduce aggression
Include pen design in welfare audits alongside enrichment quality assessment
