Routine tail docking of piglets is a painful procedure used to prevent tail biting in intensive systems, but welfare alternatives targeting root causes are increasingly viable.
Tail docking is itself a painful procedure performed without anaesthesia on young piglets, causing acute pain and potential chronic sensitivity at the stump. It treats a symptom rather than addressing the welfare deficiencies that cause tail biting. However, keeping pigs with intact tails in poorly designed systems risks outbreak of damaging tail biting. The welfare solution is to improve husbandry conditions so that intact-tailed pigs can be kept humanely.
