Routine tail docking of piglets is performed to prevent tail-biting, but it treats a symptom rather than the cause. Evidence consistently shows that improving the environment eliminates tail-biting without mutilation.
Pig tail docking exemplifies how intensive farming systems use mutilation to manage welfare problems created by the production system itself. Tail-biting results from frustration, crowding, competition, and inadequate environmental stimulation — all problems rooted in barren, intensive housing. Providing straw and rooting material addresses the root cause. Tail docking addresses the symptom while creating a new welfare problem (neuromas) and leaving the underlying environment unchanged. The EU ban reflects the scientific consensus that routine docking is unnecessary when the environment meets pigs' needs. Effective enforcement and the provision of enrichment materials are both needed to end a practice that is simultaneously cruel and avoidable.
