Common ultrasound examination positions and methods for animals

Examination of pigs: The sow to be examined can be probed in the feeding barn standing freely or lying on its side, on its inner thigh and finally on the abdominal wall outside the nipple. The probe is simply coated with coupling gel and applied to the lower abdominal wall. There is no damage or stimulation during the exploration, and it has the characteristics of short exploration time, no stress and high accuracy. The images are visualized, and a positive early pregnancy can be confirmed when a dark area of a black gestational sac or a skeletal image of the fetus is seen. Early pregnancy monitoring can be performed as early as 23 days after breeding.

Examination of the cow: Rectal probe or convex probe can be used for examination. Rectal examination can be performed by directly extending the rectal probe into the rectum, with an accuracy of 99% at 32 days.


Examination of sheep: Ewes generally take a natural standing posture and keep quiet or use two legs to hold the ewe’s neck for bailout, or use a simple bailout frame for bailout. Lateral bailout can slightly advance the date of diagnosis and improve diagnostic accuracy, but it is not convenient for large groups to use. Veterinary ultrasound to detect early pregnancy can be done in lateral, supine or standing position.


The examination of other parts of the animal: the projection part of the body surface of the examined organ can be coated with coupling gel after simple hair removal. By turning the veterinary ultrasound probe, a variety of cross-sectional images of the examined organ can be obtained, which can be used to diagnose various diseases.
