My friends Mini Mare,aborted. She checked the placenta to see the fetus.
When she opened the sack, there was no fetus in there. The sack was closed with no rips. I found this odd. The mare was a good 50 to 60 days gest.
How ever she took the mare to the Vets and had her flushed just incase. Mare is fine. She didn't think to bring in the placenta to show him and just buired it. Grrr
But she did take pictures of it.
My question is... Where did the fetus go? I have never seen a mare abort that didn't have a fetus inside the placenta.
Could this be like molar pregnancies I hear about in humans?}

There is an interesting discussion on COTH about just this phenomenon, only the mare carried to term and delivered an empty amniotic sac

If the pregnancy is lost after about 35 days, some structures called the endometrial cups will be present, that secrete a hormone that causes the mare to think that she is still pregnant for a while. The actual size of the embryo is small at 35 days, and as that has died, there really won't be much visible (if your friend had closely evaluated, they might have found some small amount of solid matter - maybe dime-sized at most), and it may have disintegrated further as well.

Thank you Jos, I am sure thats what happened.
I am sure that she could of missed it as it being so very small or like you say,disintegrated.

Thank you Tracy for the link.
