Plain-English summary
A Quarter Horse mare, who had a history of having multiple abortions, aborted a mummified fetus after being pregnant for 284 days. This happened 12 days after she stopped receiving a hormone treatment called progestogen, which helps maintain pregnancy. A check-up showed that the mare had a short uterine body, which might explain her repeated abortions and could be a reason for the mummified fetus, aside from having twins. The findings suggest that her unusual uterine shape may be linked to her pregnancy issues.
Abstract
A mummified fetus was aborted at 284 days of gestation from a Quarter Horse mare with a history of consecutive abortions. The abortion occurred 12 days after administration of supplemental progestogen had been discontinued. Results of a breeding soundness evaluation revealed that this mare had a short uterine body. Other abnormalities were not discovered. This condition may have been responsible for repeated abortions in this mare, and may represent a cause of fetal mummification other than twin pregnancy in mares.
