RETAINED PLACENTA

If the placenta (fetal membranes) have not passed from the mare’s uterus within 4 hours after foaling, the uterus can become inflamed and or infected. Retained placenta can also lead to laminitis and, in rare instances, shock and death. Do not pull on the hanging placenta; this can result in serious problems.

In some mares, the placenta is not evident and it is difficult to determine whether the placenta has been retained or has been passed normally. Signs of a retained placenta include a small red to black tag seen occasionally at the vulva, or lack of an expelled placenta in the foaling area.

Mares that previously have had a retained placenta after foaling may have the problem again in future foalings. Approximately 2-10% of broodmares repeatedly have this problem. Treatment may be required to help reduce permanent fertility problems.

If you are in the San Diego area and you have a horse with a retained placenta, call Dr. Garfinkel at 619-659-1180.
