Routine tail docking of piglets is performed to prevent tail biting, but evidence shows enrichment and management changes can prevent biting without surgical intervention.
Tail docking causes acute pain to piglets and removes a sensitive body part without anaesthesia or analgesia in most cases. The procedure is a response to industrial housing conditions that cause boredom and redirected behaviour, rather than a solution to underlying welfare problems. Countries that have eliminated tail docking demonstrate that enriched housing with good ventilation, appropriate stocking density, and rooting materials can prevent tail biting effectively. Reform requires addressing the root causes rather than the symptom.
