Pig Aggressive Behaviour Root Cause Analysis

Systematic root cause analysis of pig aggression identifies management, environmental, and health factors driving welfare problems.

Key Facts

Aggression in pigs has multiple interacting causes requiring systematic investigation
Stocking density, enrichment deficiency, mixing frequency, and health problems all drive aggression
A tail biting investigation protocol assesses 15+ risk factors systematically
Root cause identification enables targeted intervention rather than symptomatic management
Training farm staff in root cause analysis improves welfare outcomes more than reactive treatment

Welfare Considerations

Managing pig aggression reactively - treating wounds as they appear - is far less effective than preventing aggression through root cause identification. Systematic investigation of risk factors identifies the specific drivers in each unit, enabling targeted interventions that address causes rather than symptoms. This approach reduces welfare costs more sustainably.

What You Can Do

Support farms using systematic root cause analysis for aggression management
Advocate for root cause investigation as a welfare standard response to tail biting
Choose pork from certified farms demonstrating evidence-based welfare problem management
