Tail biting is a serious welfare crisis in commercial pig farming that represents both acute suffering and a symptom of underlying welfare deficiencies in the production system.
Tail biting is one of farm animal welfare's clearest welfare emergencies - an active tail biting event in a pig pen involves animals in acute pain from attacks, other pigs being drawn to blood in an escalating frenzy, and a management response that rarely arrives quickly enough to prevent serious harm. The welfare burden is compounded by the slow pace of management change: tail docking treats the symptom while farms that have eliminated tail biting through management improvement demonstrate the alternative is achievable. The pain of tail wounds and septicemia is severe and sometimes fatal. Reducing tail biting requires addressing the management root causes - enrichment, space, nutrition, and social stability - rather than repeatedly treating the consequences.
