Pig Space Allowance Evidence Base

Scientific evidence on space allowances for pigs consistently shows welfare benefits above legal minimums, informing certification standards.

Key Facts

EU minimum space allowances are 0.65m2 per 85kg pig but evidence shows benefits extend to higher allocations
Higher space allowances correlate with lower skin lesion scores, reduced aggression, and more positive behavior
Higher welfare certification schemes require 20-50% more space than legal minimums
Space is not independent of other factors - pen design, enrichment, and group size all interact
Producer cost analysis shows welfare benefits of higher space against the added production cost

Welfare Considerations

The evidence base for space allowances in pig production unambiguously shows that more space improves welfare. The question is how much more, and how to balance welfare improvement with production cost. Higher welfare certification schemes translate this evidence into market standards.
