Several routine livestock management procedures — castration, disbudding, dehorning, ear tagging, and beak trimming — cause pain and stress. Evidence-based pain management can mitigate but not eliminate these welfare costs.
Routine livestock mutilations cause acute and chronic pain that is well-evidenced in multiple species. The procedures are performed for legitimate management reasons — castration prevents unwanted reproduction, dehorning reduces injury risk — but they cause real suffering that is frequently inadequately managed with pain relief. The welfare case is not against the procedures per se but against performing them without appropriate anaesthesia and analgesia. Simple, cheap interventions dramatically reduce suffering: lidocaine before disbudding, meloxicam after castration. The continued widespread performance of these procedures without pain relief represents a preventable welfare failure.
