Use of ultrasonography in bovine practice began in the 1980‟s
Detectable changes in the uterus are predictive of the estrous cycle
- Ultrasonography is particularly useful for early pregnancy diagnosis, assessing fetal health, and fetal sex diagnosis
- Ultrasonography is not associated with higher embryonic loss
- Imaging the ovaries in cattle has led to an understanding of follicular wave dynamics in this and many other species, and to new protocols for ovarian synchronization and superstimulation
- Three dimensional ultrasonography, ultrasound biomicroscopy, and computer-assisted analysis of ultrasound images will ultimately enable us to determine the precise stage of the estrous cycle based on a single examination, and the health status of individual follicles and their contained egg.

The area that has arguably benefited more from the development of ultrasound technology than any other area is reproduction in large animals. In many cases, rectal palpation has been replaced by transrectal ultrasonography for pregnancy determination, and diagnoses associated with uterine and ovarian infections.
In addition, ultrasonography has added benefits such as fetal sexing, early embryonic detection and is less invasive than rectal palpation. From a research standpoint, ultrasound has given us the ability to visually characterize the uterus, fetus, ovary,
corpus luteum, and follicles.
accurate measurements of the reproductive organs has opened doors to new areas of research and validated or refuted data from past reports.
Practical applications of ultrasound by bovine practitioners for routine reproductive examinations of cattle is the next contribution.
This technology is positioned to make to the livestock industry. Most veterinary students continue to be taught that ultrasound is a secondary technology for bovine reproductive work; however, the information-gathering capabilities of ultrasonic imaging.
