Tail docking of piglets is widely practiced in intensive pig farming to prevent tail biting. Evidence shows it treats a symptom rather than the cause — with enrichment and management, docking can be eliminated without welfare cost.
Pig tail docking is emblematic of a broader failure in farm animal welfare regulation: a practice banned in principle is widely practiced in reality because the underlying problem driving it — barren, overcrowded housing — is not effectively addressed. The welfare logic is circular: pigs are docked because they bite tails, and they bite tails because they are in environments that do not meet their behavioural needs. The evidence from farms that have successfully eliminated docking — through enrichment provision, lower stocking densities, and improved management — demonstrates that docking is not inevitable but is a response to inadequate husbandry. The welfare cost of the practice itself — acute pain during docking of neonatal piglets — is compounded by its normalisation, which prevents the industry from confronting the underlying problem. Consumer demand for higher-welfare pork and stronger regulatory enforcement are both needed to drive genuine progress.
