Tail docking in pigs prevents tail biting but causes pain and is banned in several countries. Alternatives that address root causes are gaining traction.
Tail docking is a painful mutilation performed to prevent tail biting — itself a consequence of inadequate environments. The logic is circular: intensive systems create the conditions for tail biting, then inflict pain to suppress the symptom rather than addressing the cause. Intact tail systems that successfully prevent tail biting rely on environmental enrichment, appropriate stocking density, good nutrition, and careful management of any biting that occurs. These systems exist and work commercially in several European countries. The EU ban on routine tail docking has driven innovation in intact tail management, demonstrating that alternatives are feasible. Proper enforcement of the ban, combined with investment in enrichment, is the welfare-positive path forward.
