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.
