Tail biting is a serious welfare problem in commercial pig production that causes pain, infection, and severe injury.
Tail biting causes severe welfare harm through acute pain, infection, systemic illness, and death from spinal abscess. Root causes include frustration from barren environments, poor ventilation, nutritional deficiencies, and high stocking density. While tail docking reduces the severity of damage when biting occurs, addressing root causes through enrichment and management is the welfare priority.
