Abstract

Real time B-mode ultrasound was used to detect the early conceptus in 187 Korean native cattles between days 10 and 60 after last insemination. The ultrasound diagnostic findings were systemically confirmed by palpation per rectum after the 60th day of last insemination. The embryonic vesicle and the embryo proper within the veside were first visible on mean day fl and 23, respectively. The heartbeat of the embryo proper could be detected on day 26, and the limb buds, placentomes, amnion, fetal movement, umbilical cord, optic area and split hooves were first visible on day 33, 34, 34, 44.5, 45, 32 and 48, respectively. The mean length of embryo proper was 3.8mm on day 23 which later increased to 56. 6rnrn on day 60. When ultrasound was used to detect the conceptus between days 20 and 30 after insemination and palpation per rectum after the 60th day of insemination, the accuracy rates of pregnancy detection by ultrasound scanning at days 20, 22, 24, 26, 28, 30 were 44.4, 69.2, 78.6, 87.5, 90.0, 93.3%. In summary, the early pregnancy diagnosis of Korean native cattle with ultrasound appears high accuracy rates. It is considered that ultrasound can be used in veterinary practice well.
