Pig Finishing House Welfare: Enrichment Evidence 2026

Providing appropriate enrichment in pig finishing houses is legally required across the EU and directly improves welfare by enabling species-typical rooting and exploration behaviours.

Key Facts

EU law requires provision of adequate enrichment materials for pigs to investigate and manipulate
Straw and other plant-based materials are the most effective enrichments for reducing aggression and tail biting
Hanging chains and rubber tyres provide some benefit but are less effective than manipulable organic materials
High-stocking-density finishing systems make enrichment provision more challenging but not impossible

Welfare Considerations

Barren finishing environments prevent pigs from expressing natural rooting and exploration behaviours, causing frustration and increasing risk of tail biting and fighting. Effective enrichment reduces abnormal behaviour, improves body condition, reduces mortality from trauma, and improves slaughter outcomes. Welfare is best served by providing rooting substrate, manipulable materials and sufficient space.

What You Can Do

Support pork producers committed to effective enrichment beyond minimum legal requirements
Choose higher-welfare certified pork from producers using straw-based systems
Advocate for enforcement of EU enrichment requirements for pigs
Support research into practical enrichment solutions compatible with different finishing system types
