I will give you the facts and outline the situation. What I am looking for is ideas that are "outside the box" for this mess.
I have had my mares a long time and have carefully documented years of information on each one. Last year, armed with my notes and a camera system, I didn't miss a single birth. This year, none of the mares is showing any of their usual signs. The mares are not bagging up as big like in years past. They are not swelling in the vulva area, nothing is right. All mares are kept together, fed the same things etc.
Between April 2nd and today, we have had 7 mares foal. Five have been dead fillies, 2 are live colts. (I do not think the gender is relevant, I think all the fillies being dead is just luck of the draw.) All were born within a day or two of their due dates except one. It was approx. 3 weeks early and looked a bit small. The fillies are just not getting out of the bag. In some of the cases, I am sure the foal was still alive within a few hours of birth because of the kicking. The bag shows no signs of anything strange. The foals are perfect, no signs of deformity. I have been in contact with two different vets and the first thought was that there may have been a rhinovirus infection. This is not the most likely situation because I vaccinate for this, and rhinovirus is most note-worthy for causing abortions. All these foals were full term (except one) The next thought was that they had eaten endophyte-infected tall fescue. Some of the signs for this are lack of bag developement, delayed foaling date, and thickened placenta. The horses do have less bag development than in years past, and apparently, thickened placenta. I feed half grass hay and half alfalfa that we have been putting up ourselves for the past 8 years off of the same fields. I had the hay tested. No fescue. I realize that there could still be some in there somewhere, so we researched the symptoms further. Fescue toxicity leaves the horses system within 60 to 90 days. It just so happens that we ran out of the grass hay early this year and they were on straight alfalfa starting in January, so this doesn't make sense. In case this is our problem, has anyone ever used domperidone to counteract fescue toxicity? Are their any other medications out there that would help? I have two mares left to foal and obviously I am very concerned.
Can anyone suggest anything else that might cause this problem? Both vets have run out of ideas.
Thank-you
