Sow Longevity and Lifetime Welfare in Pig Production

Commercial sow productive lifespan averages 2-3 litters before culling; welfare-focused management targeting sow longevity improves both individual welfare and system sustainability.

Key Facts

Average sow productive life in UK commercial systems is approximately 2.3 parities
Lameness and reproductive failure are the leading involuntary culling reasons
Well-managed sows can produce 8-10 litters — longevity programmes demonstrate this is commercially viable
Body condition management and floor quality are the primary longevity levers

Welfare Considerations

Short sow productive lifespan reflects management conditions that prevent animals from living into natural maturity. The welfare cost of premature culling is the loss of the remaining productive and personal life of each sow; the welfare benefit of longevity programmes is not merely sentimental but represents better health and management conditions throughout the productive life that enable longevity. Sow longevity is a composite welfare indicator that rewards investment in floor quality, nutrition, and health monitoring.

What You Can Do

Support producers with documented sow longevity programmes
Advocate for average sow productive life as a welfare reporting metric
Choose pork from producers certified under standards that reward longevity alongside production metrics
