Tail biting is a serious welfare problem affecting 5-15% of pigs in some systems - tackling root causes through enrichment, space, health, and nutrition prevents most outbreaks.
Tail biting is a welfare crisis that emerges from environments that fail to meet pig needs. It is not an inevitable consequence of group pig keeping but a symptom of insufficient enrichment, space, or health management. Root cause analysis - examining enrichment provision, health status, nutritional balance, ventilation, and stocking density - identifies which factors are driving each outbreak. Producers who systematically address root causes can maintain intact tails even in commercial settings, as Nordic experience demonstrates. This is the welfare-positive goal.
