Tail Biting Prevention Through Enrichment in Pigs

Tail biting in pigs is a serious welfare problem driven by barren environments and high stocking density.

Key Facts

Tail biting causes pain, infection, and sometimes death in affected pigs
The primary cause is frustration from inability to forage and explore in barren housing
Providing straw, rooting substrate, or hanging chains can reduce biting by up to 70 percent
EU law prohibits routine tail docking but is widely flouted due to poor enrichment provision
Farms using enriched straw-based housing routinely keep entire-tailed pigs without biting outbreaks

Welfare Considerations

Tail biting is not an inherent pig behaviour — it is a symptom of housing systems that fail to meet pigs' strong motivation to root and explore. Farms that provide adequate rooting substrate demonstrate that enrichment, not mutilation, is the correct solution. Enforcing enrichment requirements would eliminate the need for tail docking entirely.

What You Can Do

Choose pork from whole-tail enriched systems
Support campaigns to enforce EU enrichment requirements
Advocate for investment transition to straw-based housing
Reduce pork consumption or switch to higher-welfare certified options
