Tail docking in pigs is performed to reduce tail-biting injuries, but is itself a painful procedure. Understanding why tail-biting occurs and how to prevent it addresses the root cause rather than the symptom.
Tail docking causes acute pain at the time of the procedure and potentially chronic pain from neuroma formation at the amputation site. It treats the symptom — tail-biting — rather than the cause — inadequate housing and enrichment. Countries that have eliminated docking have done so not through regulatory fiat alone but through concurrent improvements in management standards. The persistence of routine tail docking in most European pig farms reflects systemic inadequacy of production conditions rather than genuine necessity.
