Routine tail docking of piglets prevents tail biting injuries but masks rather than addresses the underlying welfare problem of barren intensive environments.
Tail docking represents a welfare paradox: it prevents one welfare harm (tail biting) by causing another (the pain of docking) while leaving the root cause unaddressed. Tail biting is a behavioral disorder triggered by boredom, overcrowding, and nutritional deficiencies in barren intensive systems. Addressing these root causes through enrichment, adequate space, and good nutrition eliminates tail biting without the need to mutilate piglets. Countries that have made this transition demonstrate it is commercially feasible.
