Mare WON'T ovulate - help?

Hi all. Just wondering if any of you have any tricks to get a mare to ovulate. We've been trying to catch this mare for weeks now and she never develops a big enough folicle. She will have several on ultrasound that seem like they should mature to be viable withing 2-3 days, and upon re-checking, they will either have remained the same or have begun to shrink. This is the last mare on the farm that needs to be bred - all the others are confirmed in foal have been at least bred. We are pulling our hair out! Hormone shots are seemingly ineffective. Any ideas? We need to get this mare preggo like yesterday!

Have you teased her? Sometimes the excitement of being teased will help the follicles over the hump. Also how old is she and has she ever had this problem before or is she a maiden?

Duh! Should have put that in the OP - she is a maiden 5 year old. We currently don't have any studs on the property, which is highly unusual. Oh, but we do have a very studish gelding! He was gelded as a 5 year old and is convinced he's still got his equipment. Maybe I'll try that.

What did your vet suggest?

Shesinthebarn - I see that you are located in Canada. How is the weather where you are? Mares up in the northern regions have a shut down winter period to their cycles in which they will build follicles then recede/shrink them without ovulating. I'm in Washington and while most of my mares are cycling normally, there are a few who aren't quite there yet. They need one more cycle to pop out of it. Or, we give them a shot of Lutalyse which should bounce them into a normal cycle.

Does your mare have any edema? What does your vet say? (Or whoever is doing the ultrasounding. I do my own.) If a mare is building then receding follicles without the presence of edema in the lining of the uterus (very visible on ultrasound....pictures below.) ....then it's a sure bet that your mare is in transitional heat. After a few transitional cycles and some good weather (or a shot from the vet) your mare will come into normal, breed-able heat. Good luck!

The black, splotchy fluid is edema. Mares in normal heat will have edema. (though the amount can vary)

Mare who is NOT in heat and is 14 days pregnant. (the black circle) I outlined the uterus in white. See how there is no edema? No splotchy fluid? A mare who is not in heat will look like this, even when they aren't pregnant. Transitional mares will not have edema. That doesn't necessary mean you can't breed them without edema or on a transitional cycle, but you will probably need the drug HCG to force ovulation after breeding (on a follicle of the correct size, 35mm or larger) in transitional mares.
