Farmed Pig Stocking Density Welfare Evidence

Scientific evidence consistently shows that reducing pig stocking density improves welfare outcomes across multiple indicators.

Key Facts

EU law sets minimum space allowances of 0.65 m2 for finishing pigs over 85 kg
Higher stocking density increases aggressive interactions and tail biting incidence
Space allowances above the legal minimum improve lying time and activity budgets
Some welfare certification schemes require 20-50% more space than legal minimums
Reduced stocking density improves production efficiency as well as welfare

Welfare Considerations

The evidence base for space allowance effects on pig welfare is strong and consistent. More space allows more normal behaviour, reduces conflict, and improves welfare across multiple indicators. Consumer and retailer demand for higher-space pork products directly drives welfare improvement by making additional space economically viable.

What You Can Do

Choose pork from welfare-certified farms with higher space standards
Support retailers with credible pig welfare sourcing policies
Advocate for increased minimum space allowances in EU pig welfare legislation
