Abstract:
An ultrasonographic method for the diagnosis of early pregnancy in the rabbit is presented. New Zealand White does were artificially inseminated and their uteri were ultrasonographically examined on days 7, 8, 9 and 10 post insemination. On day 7, a low echogenicity area, located in the uterine lumen, could be regarded as an indication of pregnancy. However, on day 8, embryonic vesicles with a diameter of · about 8 mm were identifiable and countable. On day 9, embryonic vesicles developed up to a diameter of about 12 mm. Finally, on day 10, embryonic vesicles' diameter was around 17 mm and their embryonic pole was also identifiable.
