Tail docking of piglets is performed routinely in many countries to prevent tail biting, but it is a painful procedure applied to address a symptom rather than the root cause of a welfare problem.
Tail docking illustrates a common welfare dilemma: a painful procedure is used to prevent a more severe welfare problem that itself stems from inadequate husbandry. Piglets experience pain during docking and sensitisation of the stump that may cause chronic discomfort. The underlying drivers of tail biting — overcrowding, barren environments, competition for resources — remain unaddressed. The welfare-positive approach is to invest in the conditions that eliminate the need for docking: enriched housing with adequate space and rooting materials, stable social groups, and careful attention to feed and water provision. Countries that have eliminated routine docking demonstrate this is achievable commercially. The challenge is political will and economic investment rather than technical feasibility.
