Tail biting in pigs is a painful and damaging behavior that emerges from stress, boredom, and frustration in intensive systems.
Tail biting is a welfare symptom of environments that fail to meet pig behavioral needs. Rather than addressing root causes, the industry default is painful preventive tail docking. This treats the symptom while perpetuating the stressful conditions that cause it. EU law technically requires enrichment and opposes routine docking, but compliance is poor.
