Two Late Term Abortions in two weeks
We have had two mares now abort in a span of about two weeks. One on the 8th and the other yesterday the 19th..Both are in separate pastures.. both in foal to two different sires... One was 6 months along one was 5 months along. BOTH ARE MAIDEN mares.. that is about the only thing they have in common. Both have been vaccinated. Fetus' are at USDA for testing.. Negative for EHV and negative on gross examination. Still waiting to hear back for lepto testing.
Both mares are fully vaccinated, hay is good, water is clean, Mineral, salt, and protein tubs are available. Neither are in poor body condition. Im at a loss as to what is causing this. We have walked every inch of the pasture and nothing is amiss.. No plants they coulf of eaten to cause this. They dont have access to any trees...
Any other breeders have this happen with maidens. I've been cringing going out there every day now as I might find another aborted foal. My heart cant take anymore. In 20 years in horses I have never had such a bad time of it. Vet has no clue what is causing it.
Foal number one.. a little boy.. the second one was a little girl :(
How sad. I'm very sorry about your foals
Fescue toxicity? Or tent caterpillars?
Mare Reproductive Loss Syndrome
Mare reproductive loss syndrome is a term given to the syndrome that resulted in the loss of hundreds of foals (approx. 500) and spontaneous abortion in mares in central Kentucky and parts of Ohio in the spring of 2001.
Evidence points to the setae (hair-like projections) of Eastern tent caterpillars as the primary cause of the problem. They can become imbedded in the submucosal lining of the gastrointestinal tract and cause areas of inflammation and an entrance for bacteria. These bacteria can then enter the blood stream and localize in the placenta and fetus, resulting in abortion."
I'd certainly have my mares cultured and a cytology done to see if there's any kind of an infection.
I'm sorry, it's so heartbreaking to lose foals.
OMG! That is awful! So sorry!
I just bought a maiden mare. She is 6 months along. This is my first time having a mare in foal and I am so excited. But now I'm going to be paranoid.
That is tough. Too bad. I hope that this is an isolated thing. Sorry to hear it.
I would be interested in hearing what how the lab tests come back. What about toxins? Fescue? Aflatoxins? Feed in general?
So sorry for your loss:(
last year I know of 5 different breeders that had horses abort, the only thing they had in commomon was the vaccinations.
Could vaccinations trigger abortions in maiden mares? Which ones??
Oh Ghostwind, I am so so sorry for your loss. I wish I had a thought as to why, that's something we've been lucky with. I can't remember having a mare abort, we've lost a few foals and a couple of dams over the years but it was after foaling.
Do know someone locally that had a mare abort this year, they sent her to another place that had more pasture that needed grazed, there were black walnut trees in the back of the pasture :(
Sending big hugs.
