| Abstract | ||
| Responses to ovulation in rabbits depend on neural reflexes after natural mating. The stage of follicular growth and levels of estradiol (E2) could also be involved. Injection of gonadotropin releasing hormone (GnRH) gives rise to ovulation similar to natural mating 10 White New Zealand does were allocated to two groups. Control group in which two blood samples was taken for E2 determination before Iml GnRH intra-muscular injection for ovulation induction. Second group was considered to be non-receptive for natural mating and treated with GnRH. In conclusion, levels of E2 were positively correlated to ovulation induction ability in control group. Whereas ovulation induction by mean of GnRH failed to demonstrate ovulation in second group. | ||
