Pig Sow Longevity and Welfare

Average sow longevity in intensive systems is 2-3 parities, far below their biological potential, with culling driven by reproductive failure and lameness causing significant welfare concerns.

Key Facts

Wild boars can live 10-15 years while commercial sows are culled at 2-3 years
Lameness and reproductive failure are the leading reasons for premature culling
Short sow longevity reflects systemic welfare problems in production systems
Improving sow welfare through better housing and management extends productive life
Sow longevity is increasingly recognised as a welfare and economic indicator

Welfare Considerations

Premature culling masks the welfare failures causing it. Improving sow longevity requires addressing root causes including lameness, housing quality, and management stress.

What You Can Do

Track sow longevity data as a welfare indicator on farm
Investigate causes of premature culling and address systematically
Support breeding for welfare-robust genetics with better longevity potential
Advocate for longevity targets in farm assurance welfare standards
