YOU ARE OBSERVING
Twin Fetuses Aborted or Stillborn
Summary
In twin pregnancies, each fetus has its own individual placenta that must compete with that of the other for precious attachment surface area on the uterine lining. As each fetus matures in late gestation, its metabolic demands become greater and greater. Finally, one or both of the competing fetuses become stressed and signal the mare to deliver, usually prematurely.

What To Do
If your mare has aborted twin fetuses, assess the mare's general health first using the Whole Horse Exam on Post-Foaling Mare (WHE), paying particular attention to her attitude, appetite, heart rate, gum (mucous membrane) color, and temperature. Assess the vulva for tears or swelling, due to a difficult birthing process (dystocia). If both placentae are shed, do they look complete?The birth of a small stillborn fetus at 8-10 months of gestation is always cause to consider that there may be a second fetus still in the mare. Retained placenta and subsequent uterine infection is a risk after twin abortion.
