    Horse menopause?? Something else??

    Our mare, Ginger, was looked at to see if she was fit to be bred before summer. She had several infections of the uterus and was flushed for several days and given antibiotcs. She was bred the next season that she went into, and was determined not pregnant. We bred her again, and yet again, not pregnant. The vet said that there was no reason that she should not be getting pregnant, so he flushed her again for 4 days and gave more antibiotics. However, she missed her season this month.

    Is there any way that:

    1. The vet missed a fertilized egg, and the baby was flushed out during the flushes
    2. The vet missed a fertilized egg, and she is pregnant
    3. The egg survived the flushing
    4. The egg survived the antibiotics
    5. She is in a false pregnancy
    6. She's going into menopause (DO HORSES GO INTO MENOPAUSE?! lol)
    7. Something else??

    We read somewhere that if the mare looses the foal in the first 35 days of pregnancy, that she will not go into season for the rest of the breeding season. We have no idea what could be happening and are very puzzled.

    What pathogen? Was a culture and cytology done? And given antibiotics? Orally?

    She was bred the next season that she went into, and was determined not pregnant. We bred her again, and yet again, not pregnant. The vet said that there was no reason that she should not be getting pregnant, so he flushed her again for 4 days and gave more antibiotics. However, she missed her season this month.
    Again, was a cytology and culture done and if so, what were the results?

    Is there any way that:

    1. The vet missed a fertilized egg, and the baby was flushed out during the flushes
    How many days post ovulation was she checked and flushed?

    2. The vet missed a fertilized egg, and she is pregnant
    Always a possibility. You hear about missed pregnancies repeatedly.

    3. The egg survived the flushing
    Never say never, but highly unlikely.

    4. The egg survived the antibiotics
    Were the antibiotics given intrauterine? If so, again, highly unlikely. Once you compromoise the cervix, and put anything in the uterus, you have probably compromised the integrity of any conceptus.

    5. She is in a false pregnancy
    From what you are describing, probably not.

    6. She's going into menopause (DO HORSES GO INTO MENOPAUSE?! lol)
    The only species that goes through menopause is the human. Horses will sometimes, in their old age, cease to cycle, but they do not go through menopause.

    7. Something else??
    Sure. There are so many things that can be going on that they are too many to even begin listing here. Have a uterine biopsy done. You've given very little information here regarding your mare and her reproductive ability. HOw old is she? How many foals has she had? What were the results of the uterine cytology and culture? What pathogen was she treated for? What is her uterine biopsy score? Was ovulation confirmed after breeding and if so, how far post breeding did she ovulate? Is she having uterine clearance issues? Is she being followed post breeding to be sure she's not having uterine clearance issues? And so on...

    We read somewhere that if the mare looses the foal in the first 35 days of pregnancy, that she will not go into season for the rest of the breeding season. We have no idea what could be happening and are very puzzled.

    If the mare aborts or loses the pregnancy after 35 days, chances are the endometrial cups have begun forming. Once they have formed, it takes about 60 days for them to resolve. They release progesterone which will keep the mare from returning to estrus. However, you're saying that your mare is cycling and that she is being confirmed not in foal.

    Has the same stallion been involved each time? Fresh, cooled, or frozen?

    I'm not quite sure about the pathogen, and she did get a culture and it was a Strep, but I'm not sure what group. She was given 4 days of the strongest, broad spectrum antibiotic, I'll find out the name. It wasn't given orally, but it was in the flushes.

    She started getting flushed the first time right after he checked her. I'm not sure at what time in her cycle she was. The second time, the ultrasound was looking for a pregnancy, so I would guess about 14 days post last breeding. The flushings started that day because she wasn't pregnant, and lasted for 4 days. After that is when she didn't come into season.

    Yes, for 4 days.

    Thank you, that's good to know

    She had a uterine biopsy back in February before she was bred, do you think she should get another?

    She is 21 and she has had at least 4 foals. Her last foal was a few years ago, and the foal died at 3 or 4 months. Ovulation was confirmed, as the vet saw and measured the corpus ludium (sp?).

    What do you mean by uterine clearance issues?

    Each time that the vet did an ultrasound, she had very nice sized folicles. He had no idea why she shouldn't get pregnant. She is due to come into season on the 20th, so if she skips that, we will be getting concerned. She is very, very, regular in her cycles.

    Thank you so much for your help, you've given me a lot of info, and I look forward to hearing back from you.

    Yes, it's been the same stallion. It was live cover. We are considering getting him tested to make sure that he is fertile. He has produced foals, so we know that he has been fertile. We just wanted to make sure that it wasn't her fault that she wasn't getting pregnant, but when she missed her season, it threw us off.
