Abstract
Few studies were carried out concerning the hormonal profile during gestation in humped camel. The aim of the present work was to study the levels of progesterone hormone at the determined ages humped camel. The fetuses were collected from Cairo abattoir at different gestational ages and taken to the laboratory where the fetal age were determined by crown vertebral rump length (CVR), the developmental standard morphometrically methods were used. Biometrically the weight of the fetus, CVR increased with the advancement of gestational ages (1 st trimester to the 3 rd. trimester). The hormonal profile of progesterone was estimated by RIA. The progesterone values showed increasing pattern of 1.8 ± 0.79 ng/ml, 2.38 ± 1.00 ng/ml and 2.95 ± 1.3 ng/ml for the first (up to 4 months), second (4 to 8 months) and third stage of pregnancy (9 months up to full term) respectively. Moreover, this pregnancy may be confirmed by the ultrasound. While in the second stage of pregnancy (4-8 month) it is quite difficult to detect the age of the fetus by ultrasonography; since the fetus is large in size the hormonal level may be of value to determine (approximately) the fetal age.
