Tail docking of piglets — removing the tail to reduce tail biting in later life — is the subject of major welfare reform efforts across Europe. While routine tail docking is illegal under EU law without clinical justification, it remains near-universal in practice, and the underlying causes of tail biting are poorly managed.
Tail docking itself is a painful procedure performed without anaesthesia in most systems. The underlying cause of tail biting — frustration from barren, crowded environments — is not addressed by docking; it merely reduces the consequences. Intact-tail systems require substantially more enrichment provision, higher space allowances, and more attentive stockmanship. Danish and Finnish research shows tail biting can be managed without docking through provision of rooting materials, adequate water access, appropriate stocking density, and early warning monitoring systems. Welfare reforms must address both the immediate pain of docking and the environmental causes of biting behaviour.
