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.

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.
