Tail docking of piglets — cutting off the tail to prevent tail biting by pen mates — is widely practiced but banned in the EU unless specifically justified, creating an ongoing welfare and regulatory conflict.
The tail docking paradox in EU pig farming illustrates a broader welfare failure: a painful procedure (docking) is used to prevent another welfare problem (tail biting) that arises from poor husbandry. The regulatory ban on routine docking has not been effectively enforced, meaning most EU pigs continue to have tails docked as day-old piglets without anesthesia while the underlying causes of tail biting remain unaddressed. Effective resolution requires addressing the root causes: providing adequate enrichment, rooting substrate, appropriate stocking densities, and good nutrition. Countries and facilities that have achieved intact-tail rearing demonstrate this is commercially feasible. The enforcement gap between EU law and practice represents a major ongoing animal welfare failure.
