So here is my situation. My mare is on her 3rd day of standing heat, but wouldn't let the stallion do his thing. She is a maiden mare, so Figured it would be in the best intrest of everyone to do a ground collection and AI the mare my self since my stallion is trained for ground, and I ai most of my mares anyway. Collection went well. We put the mare in the stocks and I gloved up and prepared to breed her.

When I felt her cervix it was down toward the bottom of vaginal cavity but closed. She is a tense mare when it comes breeding time and was very tight vaginally for me to enter with my hand and arm almost to the point of not getting in (Even though I have a small hand and arm). I would of swore she wasn't in heat, but I palpated a 35mm+ soft follicle this morning. We had previously did a bse and all was normal and no hymen. Could she just be "tense" or is there a problem I'm not thinking of? I've never had a mare act this way when I'm AI'ing her. She is a bit small, but I've bred much smaller mares than her with no trouble. Any advice would be much appreciated.

Isn't the definition of "standing" heat when a mare allows a stallion to mount? If she isn't standing and was allowing him before I would think she has past the "standing" heat phase and is coming out of heat. Therefore it is no surprise that her cervix would be tightening up.

Remember that "presence of a follicle alone does not a mare in estrus make"!!! Mares produce mid-cycle follicles (and may even ovulate on a mid-cycle follicle), but you sure don't want to breed on a mid-cycle follicle! Putting semen into a diestrus mare is probably going to end in a bad situation (uterine infection).

Remember too that some mares will display estrus-like submissive behaviour, even though they are not truly in estrus - and typically those mares will, when "push comes to shove" and the stallion goes to mount, finally change their minds and say "no". If you are dealing with a mare that is not displaying total receptivity to the stallion, then ultrasound is going to be needed in the absence of obvious signs (follicle + relaxed cervix). With ultrasound you can not only visualise the ovaries, but also determine if there is uterine edema present - a sure indicator of estrus.

If the mare is truly in estrus, then it may be - especially as she is maiden - that the cervix is not going to relax until she is close to ovulation. "Not all cervices are created equal" is another maxim for you... :-)

Finally, as noted above, unless you are ultrasounding, there is a possibility that the mare has ovulated and what you are palpating is a CL and not a follicle - it can be impossible to differentiate between the two no matter how experienced the palpator is at certain points in the cycle.

Thanks for the advice. My sister (who is a vet) ultrasounded her last night, and shes sure the mare is in estrus. She's thinking its just that shes a maiden mare causing the tight cervix, although, she bred her and had little diffuculty ai'ing her and said she felt pretty good. She said we should breed her again tomorow.

Nicole,
I know how this emotional roller coaster ride can get! You have an ace, Your sister! Hopefully everything will work out fine and you will be in the 2008 foal crop.
