Pig Pen Enrichment Design Science

Scientific evidence on pen enrichment design identifies the characteristics that make enrichment most effective for pig welfare.

Key Facts

Enrichment must be destructible, deformable, or consumable to maintain pig interest
Hanging chains alone have limited welfare benefit without additional substrate
Straw is the most effective single enrichment material for pigs
Enrichment should be accessible to all pigs simultaneously to avoid competition
Novel enrichment introduced regularly maintains engagement better than static provision

Welfare Considerations

The science of pig enrichment design moves beyond simply providing objects to understanding what characteristics maintain engagement. Materials that can be rooted, chewed, and destroyed satisfy multiple behavioural needs simultaneously. Designing enrichment systems based on this evidence rather than minimum compliance approaches significantly improves welfare outcomes.

What You Can Do

Support welfare standards based on enrichment design science rather than box-ticking
Advocate for enrichment quality requirements in pig welfare certification
