Tail docking in pigs is a welfare harm justified by preventing tail biting, but evidence shows enrichment addresses root causes more effectively.
Tail docking removes painful nerve endings from the tail causing acute pain without analgesia. The regulatory intent is that enrichment should prevent biting making docking unnecessary. However, poor enforcement allows routine docking as cheaper than enrichment provision. Countries including Finland and Sweden demonstrate that tail biting can be managed without routine docking through appropriate enrichment, representing the regulatory and welfare goal.
