Camera-based automated detection systems are emerging as practical tools for identifying the early stages of tail biting in pig facilities, enabling timely intervention before serious injury occurs.
Tail biting in pig facilities represents a serious welfare problem that is both a symptom and a cause of suffering. Affected pigs experience pain from wounds that can penetrate deep into vertebral tissue, and the behavior typically reflects an environmental failure — inadequate space, poor air quality, insufficient enrichment, or social stress. Traditional detection relies on farm worker observation, which is limited by staff availability and the rapid escalation of outbreaks. Automated camera detection systems offer earlier warning, allowing management intervention before serious injury occurs. However, detection technology is ultimately a monitoring tool rather than a solution — addressing the environmental factors that trigger tail biting is the only sustainable welfare improvement.
