Tail docking removes pain sensitivity but does not address the root causes of tail biting. Prevention through enrichment and management is a superior welfare approach.
Tail docking addresses the symptom - tail biting injuries - by removing the target, while leaving the underlying welfare problem untreated. The docking procedure itself causes acute pain. Prevention through enrichment, appropriate stocking density, and management is both more welfare-positive and more effective at addressing root causes of tail biting in pig populations.
