Farm Animal Welfare

Pig Environmental Enrichment Evidence Base

The evidence for specific enrichment materials and their effectiveness in improving pig welfare is now substantial and should inform regulatory standards.

Key Facts

Straw is the most effective enrichment for pigs because it satisfies rooting behavior specifically
Organic materials are consistently preferred over inorganic objects in choice tests
Novelty of enrichment matters - familiar objects are less effective than new materials
Enrichment reduces tail biting by 50% in some studies when appropriate materials are used
EU regulations require manipulable material but do not specify quality requirements

Welfare Considerations

Welfare regulations that require enrichment without specifying quality allow minimal provision that does not actually improve pig welfare. Evidence clearly identifies what works and what does not. Regulations should specify evidence-based requirements, not just enrichment presence.

What You Can Do

Support campaigns to strengthen enrichment requirements to specify quality, not just presence
Advocate for straw or equivalent organic material as a minimum enrichment standard
Choose pork from farms demonstrating evidence-based enrichment provision
