Mummification of fetal membranes in the bovine vagina: A case report

摘要

Papyraceous, mummified fetal membranes were found in the vagina of a cow at the end of the fourth month after a normal delivery. The uterus and cervix were without any pathological changes. The cow conceived on Day 36 after removal of the mummified fetal membranes upon the second insemination. Apart from the uncommon nature of the case, it proves that after calving the bovine vagina can maintain a sterile environment and that the constrictive mechanism of the vagina can be strong enough to hinder for a long time the discharge of fetal membranes and access of microbes to the vagina.
