Just a question for you AI experienced folks. When doing AI in the mare, where is the urethra of the mare vs the cervix? Is the urethra close to the cervix area? Sometimes it's sort of confusing in there when you are palpating for the cervix? Can anyone tell me the relationship between these two anatomical structures?

The urethral opening not at all close to the cervix, as it is not even really inside the vagina, being before the vaginal vestibular seal, so it is very well removed from the cervix. There should be no confusion when palpating the cervix!

Thanks for the info. I was surprised by the change of the shape of the cervix in two days with a mare that must have taken right away with the first AI dose and wondered if that could really be the cervix. I knew the urethra was in there somewhere and couldn't find any text or anything on the net to tell me where it was. Thanks for your help.

Estrogen, which is secreted by the follicles, causes relaxation of the cervix; progesterone, which is secreted by the CL (which is what is formed following ovulation in the evacuated follicular space) causes a tightening of the cervix. It is likely therefore that your mare had ovulated and that was causing the change in the shape and tone of the cervix. Note that this change in itself does not indicate pregnancy!
