Routine tail docking of piglets is performed to prevent tail biting injuries but is itself a painful mutilation that enrichment-focused management can often make unnecessary.
Tail docking is a paradigmatic case of mutilating animals to compensate for inadequate management conditions. The pain of tail docking in young piglets (without analgesia in most commercial settings) is exchanged for reduced risk of tail biting injury in inadequate environments. But the inadequate environments themselves cause welfare harm through the behavioral frustration that drives biting in the first place. The welfare-optimal approach — investing in enrichment, space, and management quality sufficient to prevent tail biting without docking — has been demonstrated as commercially viable. The barrier is economic: enrichment and space cost money that competitive market pressure resists absorbing without regulatory requirements.
