veterinary B-ultrasound technology has become a widely used in vivo diagnostic method for medical diseases, providing good, stable, safe, and rapid theoretical and guidance for animal pregnancy and diagnosis. The Veterinary Ultrasound imaging diagnostic technology is of great help in monitoring ovarian follicle development and controlling techniques such as follicle counting, estrus synchronization, superovulation prediction, and superovulation response for early pregnancy diagnosis (estimating multiple pregnancies, measuring follicle, corpus luteum, and fetal size) and early fetal gender identification.

Application in early pregnancy diagnosis of dairy cows. Compared with traditional rectal examination methods, the animal B-ultrasound rectal detection method has great advantages. Cows generally undergo rectal examination 2-3 months after mating. The application of animal B-ultrasound rectal detection method for early pregnancy diagnosis mainly involves observing amniotic fluid and, if necessary, assisting in the detection of follicles and corpus luteum on the ovaries.

Application in early pregnancy diagnosis of sheep. Veterinary B-ultrasound diagnosis of early pregnancy in ewes can accurately distinguish pregnant sheep from empty pregnant sheep. This can enable re breeding or processing of empty sheep, save feeding costs, and increase feed returns; It can also optimize the management of pregnant sheep, effectively prevent the occurrence of miscarriage, difficult labor, and pregnancy toxemia, and reduce production losses

Application in early pregnancy diagnosis of pigs. The B-type tomography scanner for animals can observe images of the ovaries and reproductive tract sections of sows, which is more accurate and intuitive than the A-type and D-type scanners. The sow lies supine or stands in a stable position, and slides and scans the urinary and reproductive tract of the sow in a fan-shaped manner with the probe parallel to the body axis between the nipple and the abdomen near the inner thigh of the hind limb. Early embryonic death and absorption can be monitored based on changes in the gestational sac. Mainly monitoring the estrus cycle of the uterus, monitoring postpartum uterine involution, monitoring uterine diseases, early pregnancy diagnosis, etc.
