Fecal Estrone Sulfate Profile of a Sow Showing Abnormal Pregnancy with Fetal Mummification

Abstract

Fecal and plasma E₁S of a sow with mummified fetuses, was compared with normal delivery cases. Fecal and plasma fluctuation patterns in E₁S were similar. In the sow with fetal mummification both fecal and plasma E₁S concentration rapidly decreased after day 80-90 compared to normal farrowing sows. This coincided with the estimated time of fetal death.
