Pig Enrichment Science: What Works in Practice

Evidence-based review of enrichment provision for pigs and what genuinely improves welfare.

Key Facts

Rooting materials are the most evidence-supported enrichment for pigs
Novel objects provide brief stimulation but require regular replacement
Social enrichment through stable group housing reduces aggression
Foraging enrichment reduces tail biting risk substantially
Enrichment quality and quantity standards in EU legislation are minimum thresholds

Welfare Considerations

Pig enrichment science in 2026 shows clearly that rooting and foraging materials are the most effective welfare interventions, reducing tail biting, aggression, and stereotypic behaviour. Novelty is beneficial but short-lived. The welfare priority is ensuring sufficient quantity and appropriate type of enrichment, not simply ticking compliance boxes with inadequate provision.

What You Can Do

Support pork certification schemes with meaningful enrichment requirements
Advocate for enrichment quantity and quality standards beyond minimum compliance
