Ultrasonographic Imaging to Monitor Early Pregnancy in the Camel (Camelus dromedarius)

Abstract

Six female one-humped camels of Bikaneri breed were mated with virile studs when follicles equal to or larger than 9 mm in diameter could be observed ultrasonographically. Real time B-mode ultrasound was used to detect and monitor the early conceptus, its growth and anatomical features between days 18 and 40 postmating. The embryonic vesicle and embryo proper within the vesicle were first visible on days 18 and 23 postmating, respectively. The heartbeat of the embryo proper could be detected on day 30. The allantois and amnion were first identified on day 40. The optic area was first identified on day 40 postmating. The ultrasonography method can help to identify pregnant or nonpregnant she-camels as early as day 20 of pregnancy, the results being available instantaneously.
