Tail biting in pigs is a welfare emergency driven by barren environments, and environmental design changes can dramatically reduce its occurrence.
Tail biting in pig farms is a welfare emergency that cascades: when one pig begins biting, others join, and the wounds attract further attention from pen-mates. Victims suffer severe injury and chronic pain, and the perpetrators are expressing frustrated behavioral drives in the only outlet available to them in barren environments. The solution is environmental: providing enrichment substrates that satisfy rooting and chewing behavior, ensuring adequate space, and monitoring for early warning signs that allow intervention before outbreaks escalate. These environmental changes prevent both the welfare harm of biting and the reactive harm of tail docking.
