Tail docking is routinely performed on piglets across European and global pig farming to prevent tail-biting injuries. Addressing the root causes of tail-biting can eliminate the need for this painful procedure.
Tail docking is a welfare compromise that treats a symptom rather than the cause. Piglets are docked without anaesthesia - the procedure is acutely painful and causes lasting sensitivity in the tail stump. Yet tail-biting outbreaks in undocked pigs cause severe injury - victims may be bitten to death. The genuine welfare solution is to remove the conditions that drive tail-biting: provide rooting material, adequate space, proper nutrition and healthy social groups. This is achievable and the evidence from intact-tail farming systems demonstrates it. Continued routine docking represents a policy failure, not an agricultural necessity.
