ABSTRACT The B-mode and color Doppler ultrasonography provide a safe, non-invasive, real-time approach to assess reproductive tissues and organs in female cattle, and thus have a number of potential uses in reproductive management. On the ovary, antral follicle population can be counted, and follicular growth, regression and ovulation can be monitored during sequential exams. The corpus luteum can be identified, and evaluated according to size, echotexture, and vascularization. Ultrasonography allows an early diagnosis of pregnancy based in the detection of the embryonic vesicle from day 24 of gestation. Alternatively, non-pregnancy can be indirectly inferred according to corpus luteum vascularization 20 days after insemination. Embryo and fetus morphology and vital signs can monitored throughout gestation, and fetal sex can be determined by the visualization of the relative position of the genital tubercle. In addition, a range of pathologic conditions of the ovary and uterus can be diagnosed based on sonographic images. The use of ultrasonography was also key for the development of many assisted reproductive technologies, such as timed artificial insemination, modern superovulation protocols, procedures for the recovery of cumulus-oocyte complexes aiming in vitro embryo production, and is a valuable tool for the selection and management of embryo recipients. In the future, emerging technologies such as computer-assisted image analysis, 3D ultrasonography, and 3D modeling have the potential to improve the accuracy of sonographic diagnosis, or even create new potential uses for ultrasonography in animal reproduction.
