Pig Tail Biting: Welfare Crisis on Intensive Farms

Tail biting in intensive pig farming is a serious welfare problem driven by frustration and abnormal behaviour in barren environments.

Key Facts

Tail biting affects up to 30% of pigs in some intensive systems
Routine tail docking is common in EU farms despite being illegal without prior assessment
Biting can escalate to severe cannibalism causing significant injury
Barren environments lacking rooting material are a key risk factor
The EU Pigs Directive requires enrichment material but compliance is poor

Welfare Considerations

Tail biting inflicts painful wounds on victims and reflects severe welfare deficiency in the biters, indicating frustrated behavioural needs. Pigs are highly intelligent and motivated to root and explore; denied these outlets in barren concrete pens, redirected aggression toward penmates causes cascading injuries. Wounds become infected, attract further biting, and can lead to spinal abscesses and death. Docking tails without pain relief causes acute suffering and does not address underlying welfare failures.

Support enforcement of enrichment requirements for pigs in your region
Choose pork products from higher-welfare systems with outdoor or deep-straw access
