Pig Sow Longevity and Culling Welfare

High sow turnover rates in commercial pig production reflect welfare problems that cause early culling, and improving longevity benefits both sows and productivity.

Key Facts

Average sow productive life in UK commercial herds is 2.5-3 years before culling
Lameness, reproductive failure and body condition loss are the top culling reasons
Each additional parity represents improved feed efficiency and lower replacement costs
Gilt rearing management strongly influences lifetime productivity and welfare
Reducing first-parity reproductive stress improves longevity across the entire sow's life

Welfare Considerations

Short sow productive lifespans reflect chronic welfare problems. Improving longevity through better management benefits animals, farmers and the sustainability of pig production.

What You Can Do

Support farms demonstrating high sow longevity as a welfare indicator
Ask producers about their sow replacement and culling policy
Advocate for sow longevity metrics in welfare certification standards
