The Science of Environmental Enrichment for Pigs

Environmental enrichment is essential for pig welfare, reducing harmful behaviours and improving psychological wellbeing in farm settings.

Key Facts

Pigs need daily access to manipulable rooting materials under EU law
Straw is the gold standard enrichment material for indoor pigs
Inadequate enrichment leads to tail biting, which causes significant suffering
Pigs prefer novel enrichment and habituate quickly to static items
Enrichment also improves meat quality by reducing stress hormones

Welfare Considerations

Pigs are intelligent, curious animals with strong behavioural needs to root, explore and manipulate their environment. Barren environments cause chronic frustration, boredom and redirected behaviours including tail and ear biting that spread rapidly through groups. Enrichment provision is therefore not optional but a fundamental requirement for adequate welfare. Research shows that effective enrichment requires multiple materials, novelty and accessibility throughout the day.

What You Can Do

Support pig farms with confirmed provision of manipulable enrichment
Advocate for strong enrichment standards in national farm assurance schemes
Choose pork from outdoor or straw-based systems where possible
Support research into cost-effective enrichment for intensive systems
