I wanted advise on whether or not my mare may be pregnant, even though the vet today thought she was not. She had started showing in heat (let my gelding mount and penetrate her!) by Friday, June 8th. Took her to the stallion and did on-farm AI on Monday, June 11th. Took her home. Gave her a shot of oxytocin 6 hours post breeding, then two more following in the proper time frames, since she has had a tendency to retain some fluid in the past. She teased to my gelding until she was mildly interested in the AM on Thursday, June 14th, then definitely out. Did not have her checked by the vet during this cycle, I should add, so we do not know when exactly she ovulated.
Had the vet out today. It would be 16-17 days after last signs of estrus, although this mare has routinely showed 1-2 days post ovulation in the past. Now, this mare is 17h and has a uterus that is stretched down and it makes it very hard for the vets to see her whole repro tract. This is what the vet said when he checked her today:
He didn't think she was pregnant, since he did not see a vesicle/embryo (he was pretty sure he saw the whole tract, but has had trouble in the past). He said she had just a little bit of edema, cervix was closed, a couple of follicles present, but under 20mm, and "not a significant CL".
This mare, who usually shows many days before ovulation and strongly to just about any horse on the property, is not interested in breeding or teasing at all. In her last cycles, she would start to show a day prior to last last cycle (ie: she started to show on a Sat. 2 cycles ago, then the next cycle it was Friday), so she would be late, unless her last heat cycle was abnormally long. My questions are:
Can a mare have some edema in her uterus (at least a small amount like my mare has) if she is bred? Should the CL be quite large if she was in a 16-19 day pregnancy, or could it be small? What are the chances that this mare had an early abortion? What should I do? With the July 4th holiday coming, it makes it hard to wait and watch, but that may be what I will have to do.
I'd appreciate anyone's advice. My gut is telling me the mare may be bred. She's been acting different for the past week or more. That may sound weird, but I pay close attention to my horses and I just thought she was, and with her not back in heat yet and the fact that she's been hard to check in the past, I don't know??? How often does it happen that a vet will be wrong at this stage in a pregnancy?
hello i have been wondering or not if my mare is pregnant....i have only owned her for 3 months and the person i bought her from said she may have been out in the pasture with the stallion...but also i cant tell if she is in heat either...how do you tell??...and her belly has been getting big lately...so i am wondering if she is pregnant or not....and she has been sweating alot and our gelding just wont leave her alone... like he keeps agervating her...so what do you think is up with her??
What was her uterine tone when your vet checked her?
