Premature lactation and retention of a mummified fetus with live birth of the co-twin in a primiparous Morgan mare

摘要

This report describes a primiparous 8-year-old Morgan mare, which displayed premature lactation that began at approximately 240 d of gestation and lasted approximately 4 wk. The premature lactation resolved spontaneously, and the pregnancy was subsequently carried to full term with the delivery of a live foal and a mummified fetus.
