The Thoroughbred mare that I co-own was ultrasounded for the first time on Friday since being in our ownership. She wasnt showing signs of heat, but we decided to ultrasound her anyways. We found small amounts of fluid and the uterus, and no breedable follicles, she had a 24mm on one of the ovaries, but other than that, nothing. But, her cervix was open, we were able to get a sample for a uterine biopsy. She is 10 years old, and has had 5 foals before.

Any ideas on why the cervix is open, with no breedable follicles?



Thanks!

Sure. Easy :-). She's still transitional. In order for the cervix to be closed there has to be an elevated level of progesterone. Progesterone comes from the CL. The CL is formed following ovulation. Mare's don't ovulate when in anestrus or transitional. Hence, no closed cervix.

I got her biopsy results back.

Does anybody have an email address I can forward the results to, and possibly explain the results a bit more. They are in "vet" talk. My vet said that she has a Grade II, A uterus.

But I would love to forward somebody the email, to see what you think.
