Abstract:
The present study was conducted for pregnancy diagnosis and determination of gestational age by measuring the diameter of embryonic vesicle (mm), length of the embryo proper (CRL, crown rump length, mm) and diameter of the foetal head (BPD, Biparietal Diameter, mm) in 30 does using transrectal and transabdominal ultrasonography. The embryonic vesicle was possible to detect from day 19 after breeding onwards with a diameter of 10.52 ± 0.58 mm and increased gradually till day 35 after breeding with the diameter of 28.21 ± 0.33 mm using transrectal ultrasonography. But by transabdominal ultrasonography it was possible to detect the embryonic vesicle from day 25 after breeding onwards with a diameter of 18.16 ± 0.91mm and gradually increased to 27.45 ± 0.48 mm till day 35 after breeding. The second parameter is the measurement of the length of the embryo proper. The embryo proper was first visible on 21 day after breeding with a diameter of 6.99 ± 0.36 mm and gradually increased till day 50 after breeding with a diameter of 42.09 ±0.87 mm by transrectal method. But it was not possible to measure the fetus due to increase in size of the fetus. The embryo proper was visible on day 25 after breeding with a diameter of 8.31 ± 1.52 mm and gradually increased till day 50 of pregnancy with a diameter of 41.52 ± 1.07 mm by transabdominal method and also similarly it was difficult to measure the length of the embryo after day 50 after breeding. The third parameter was the measurement of the BPD. It was possible to detect the foetal head only after day 40 after breeding by both the methods with a diameter of 23.79 ± 0.29 mm and 23.49 ± 0.42 mm but was not possible after day 80 and day 90 after breeding by transrectal and transabdominal ultrasonography. The present study could be concluded that it was possible to detect pregnancy as well as the gestational age by measuring all the three parameters.
