Farm Animal Welfare

Pig Pen Density and Space Allowances

Stocking density in pig pens directly affects aggression, stress, air quality, and access to resources - a fundamental welfare determinant.

Key Facts

EU regulations set minimum space allowances of 0.65-1.0 m2 per pig depending on weight
Scientific evidence suggests higher space allowances substantially improve welfare outcomes
Overcrowded pens increase aggression, tail biting, and respiratory disease incidence
Resource provision (feeders, drinkers, enrichment) must scale with group size
Higher space allowances are associated with reduced antibiotic use on monitored farms

Welfare Considerations

Stocking density is one of the most directly controllable welfare parameters in pig farming. While minimum legal standards exist, the evidence suggests that exceeding them produces meaningful welfare improvements that also benefit production outcomes.

What You Can Do

Support pig farms operating above minimum legal space allowances
Advocate for evidence-based space allowance increases in pig welfare legislation
