High sow culling rates in commercial pig production represent both welfare failures and economic inefficiency. Longevity management improves both outcomes.
Sows culled prematurely suffer the welfare impacts of the conditions causing culling, then the stresses of transport and slaughter. Proactive management that prevents lameness, reduces prolapse risk, and maintains reproductive health extends productive life with welfare benefits throughout. Longevity and welfare are mutually reinforcing goals in sow management.
