HI, mare was US at 2 months/ vet stated open w/ very little activity on left ovary, no edema and would be a long time before she was to come in heat/prior to this I had been checking her back to the stallion and she just pinned her ears and kicked/ also checked her cervix which was high and tight ///did this a couple different times. YET mare acts pg/ so decided to have another vet check 3 days later than the first...open but uterus was elongated (??) slight activity on left ovary and would be awhile before she came back in, no edema. Waited couple days and she started showing heat although not like shw normally would/ pee'd some and turned her butt to the younger stallion so decided to get her up and recheck her again to the older mature stallion...she pinned her ears and tried to kick...the stallion was excited BUT not like he usually gets when a mare is truley in heat and either getting ready or is hot...so sleeved her ...cervic was up tight and when I touched her inside she tightened it more...plus outer observations her labia were puckered up and not lax like a mare is when in heat...COULD SHE ACTUALLY BE PREGNANT AND BOTH VET US NOT FIND IT??? no fluid was seen inside/ could there be an infection of sorts??? w/o seeing fluid...this is really weird for her. Any advice / comments greatly appreciated. Susan Adrian , MO
Although a little earlier than normal, the pregnancy may have descended over the pelvic brim into the adominal cavity and out of reach of the palpator/ultrasonographer (this is more common 90+ days, but does sometimes happen earlier).
If in doubt, check her again by u/s or palp. at 150+days, and/or blood hormone assay (for estrone sulfate or total estrogens) at 100+ days.
