Pig Sow Longevity Welfare and Economics

Short productive lifespans in commercial sows reflect welfare problems and represent economic waste, making longevity a convergent welfare and business target.

Key Facts

Commercial sows are culled at an average of 2.5-3 parities, far short of their potential 8+
Lameness, reproductive failure, and prolapse are the leading culling reasons
Genetic selection for hyper-prolificacy has compromised sow body condition and longevity
Farms with higher sow longevity show lower replacement costs and better workforce welfare indicators
Higher welfare sow management directly improves longevity metrics

Welfare Considerations

Short sow lifespans are both a welfare indicator and an economic signal. Sows culled prematurely reflect accumulated welfare failures including lameness, exhaustion, and reproductive problems. Improving management to extend productive life benefits both sows and producers.
