Good afternoon....hoping for success 2nd time around with AI. Mare was checked Tues., had 38 follicle, measured 2 on speculum and had edema 3, anyway, we hurried and got semen for Wed. Did AI, Next day, we checked and she had ovulated, vet flushed her out with like 4 bags of fluid and antibiotics, put her on oxytocin. We did not use the 2nd dose of semen, as she had ovulated. Vet said she needed to come back this am and treat her again, she flushed her once more with one bag, said she looked much better. She had no infection, just a bunch of tissue, which she said is not uncommon for older broodmares. ANyway, I'm giving oxytocin today and tomorrow. I notified stallion owner of ovulation...she wrote back and said the vet still should have given the 2nd package of semen even after she had ovulated...now I'm worried, I have always trusted my vet. She AI'd Sweetie in 07 with one dose, we through out the other and the mare was pregnant...what is everyone's feelings on this? I guess I thought, ovulation was good and why put more in her uterous if we didn't need to? Advice/Input anyone?
According to what you have written, you have a mare that has uterine clearance issues. Sperm are inflammatory, and cause the uterus to release inflammatory cells. This results in an inhospitable environment and pregnancy loss in mares that are unable to clear them ("delayed uterine clearance" - "DUC").
Your mare was inseminated just prior to ovulation, which is ideal. Your vet is managing DUC issues with oxytocin and lavage. to put an additional dose of irritant (semen) into the uterus at a time when the mare had already ovulated would simply irritate the uterus more.
If your mare is not pregnant, it will not be because she didn't get the second dose of semen...!
Thank you Jos! This is what I was hoping you would say. I do trust my vet, and I just don't want the stallion owner to say it's because we didn't give the 2nd dosage. I'm keeping my fingers crossed and hoping for the best! Kim
