How do you palpate a pregnant mare?
To prepare a mare for palpation, she is positioned with her hind end pointing out of the stall into the breezeway. There is a handler at the mare’s head and another at her hindquarters. The handler at the hind end is responsible for holding the tail aside to create a clear path to the rectum.
When should you palpate a pregnant mare?

What is the earliest day that pregnancy can be diagnosed by rectal palpation in the mare?
A developing embryo can be visualized as early as day 12 to 14 days of gestation, where rectal palpation alone can detect pregnancy by 30 to 35 days of gestation. Unfortunately, in miniature mares, rectal palpation is usually not a very safe option when weighing the danger of manually tearing the rectum.
Which method is used to evaluate a mare when she becomes pregnant?
Ultrasonography can be used to obtain a visual image of the mare’s reproductive tract, and thus to detect pregnancy before palpation is normally performed. Ultrasonography is normally used following the 14th day post-breeding, but it can detect pregnancies as early as 10 days post-ovulation.
How do you check a horse for pregnancy?
Ultrasound: A vet places a probe in the rectum of the mare and sound waves are used to generate a picture of the uterus, the foetus and placenta. It can also detect the foetal heartbeat.

Signs of estrus include opening and closing (“wink- ing”) her vulva, tucking her hips (“posturing”), urinat- ing, raising her tail, and interest in the stallion.
