HMG (made in china), PMSG and hcG on superovulation of 40 female rabbits are studied. Results indicate that the HMG(made in china) has a very good superovulation effect on rabbit. Among the treated animals 90% responded to the treatment and the average of embryos per rabbits collected is 30.2, 103 embryos were collected. 7.6 embryos were collected per rabbit. The difference is great (P<0.01). The superovulation respose of rabbits is better in spring than in Autumn.
