Complete necropsy findings and data are provided for 107 females. The locomotor, gastrointestinal, reproductive, and urinary systems were affected with lesions presumably causing death; however, lesions affecting the respiratory and circulatory systems also were evident. Sow death was more common during gestation and lactation than in the breeding phase of production. Animals euthanized by farm personnel accounted for approximately 40% of deaths. A group of 88 cull sows was examined at slaughter to discover the distribution of lesions in the surviving population. The proportion of animals with lesions differed between the culled and necropsied sows. ER -
