Ovulation induction using GnRH and hCG during non-breeding season in the one humped camel (Camelus dromedarius)

Abstract

The aims of the present study were to monitor the ovulatory response following ovulation induction by GnRH and hCG, and determine the effect of GnRH and hCG on induction of ovulation. A total (19) one humped camels were used in this experiment and divided into three groups: Group (A) Camels (N=7) were intramuscular injected by 2 ml GnRH Group (B) Camels (N=6) were intravenous injected by 3 ml hCG. Group (C) without any hormonal treatment, camels (N=6) were intramuscular injected 1 ml by distilled water. In all groups ovulation was observed by ultrasonography. The proportion of she camels that ovulated during 24-48 hours in response to treatments were (6 / 7 vs 4 /6 vs 0 / 6) in the GnRH, hCG and the control groups, respectively. The results showed that were significant differences in the means + SD (P ? 0.01) between the treated groups compared to the control group. But there were no significant differences between the GnRH and hCG groups (P ? 0.05).
