Pig Tail Biting Root Cause Investigation

Tail biting is a complex behaviour with multiple interacting causes that requires systematic investigation rather than simply treating the symptom.

Key Facts

Tail biting causes painful wounds and secondary infection in affected pigs
Over 20 risk factors for tail biting have been identified including enrichment deficit and overcrowding
Nutritional deficiencies including salt and fibre can trigger tail biting outbreaks
Identifying the specific triggers in affected pens allows targeted intervention
Electronic monitoring can detect tail biting earlier than scheduled inspections

Welfare Considerations

Tail biting is a welfare emergency that rapidly escalates once started. The first step - treating wounds and removing biters - addresses the immediate crisis, but root cause investigation and management change is required to prevent recurrence. Systematic risk factor assessment using validated tools allows farms to identify and address the specific combination of factors driving biting, rather than relying on tail docking as a catch-all solution.

What You Can Do

Support pig welfare resources including tail biting risk assessment tools
Advocate for root cause investigation to be required when tail biting occurs
Choose pork from farms with documented low tail biting prevalence rates
