Pig Aggression Toward Stockpeople and Welfare

Pig aggression toward stockpeople and between pigs reflects both welfare problems and management challenges requiring systemic solutions.

Key Facts

Sow aggression around farrowing is natural but can cause serious injury to handlers
Boar aggression represents a significant worker safety concern on pig farms
Low-stress handling methods reduce pig aggression toward handlers significantly
Adequate space allowances reduce inter-pig aggression from resource competition
Pain or disease frequently underlies increased pig aggression toward people

Welfare Considerations

Aggression in pigs often reflects underlying welfare problems including pain, fear and resource competition. Addressing root causes through low-stress management, adequate space and pain treatment is more effective than reactive containment approaches.

What You Can Do

Support stockperson training in low-stress pig handling techniques
Advocate for pig welfare assessments that include human-animal relationship evaluation
Seek veterinary advice when pigs show unusually increased aggression as pain may be involved
