I have a 10 yr old mare, had one foal 4 yrs ago with no problems. Had her under lights since Nov. as I was going to breed for a Feb. foal and seemed to be cycling right on time, then had a few people interested in buying her NOT bred but the sells fell thru so decided to try and breed for a later foal. So have been trying to get her bred, she will tease for a few days, then out for a day or two, then back in and she has been doing this for the last month. Vet came out yesterday and did ultrasound, said there were follicles but they looked dormant like a mare in anestrus and no CL. He is a good repro vet but is uncertain why she is like this at this time of year! She did have ALL pre-breeding tests done, all was good to go. Anyone with suggestions??? Also, should I continue teasing this mare, will it help stimulate her in anyway or am I just wasting my time??
Did you turn off the lights when you thought you had a sale for her? If so, she may have gone into anestrus.
If not, you would be well advised to run a progesterone assay series - you may need to run as many as 3, each 1 week apart - and if there is is no progesterone present after 3 then you have confirmation that she is anestrus. If however she has a level >1ng/ml then she is cycling.
Teasing will not stimulate the mare. She's either cycling or not, teasing won't make a difference, although of course it may tell you when she is in estrus, if she is.
Thank you for the information Jos. We did not turn off the lights at anytime until just last week when the daylight hours have been longer. I will call the vet back and have progesterone tested. Again thank you, your advise is always greatly appreciated!!
