摘　　要：本文通过对低剂量PMSG、FSH、AI+ET鲜胚移植和冻胚移植的试验,得出应用三种激素试验结 果。FSH试验组受胎率、双犊率分别比低剂量PMSG试验组提高4％和6.6％,比PMSG试验提高4％和 8.6％。AI+ET试验组双犊率高2％,比冻胚移植双犊率高8％。Two experiments were conducted with the fresh embryo and freezing embryo implanted in the uterine hom under conditions of the lower dosages of PMSG, FSH and AI+ET, and results showed that the pregnancy rate and twins rate in the FSH group were higher than those of in the lower dosages of PMSG group, which were 4% and 6.6% respectively, and they were 4% and 8.6% higher than those in the normal dosages of PMSG group. It also indicated that the twins rate was 2%higher than that of the AI+ET experimental group, and it was 8% higher than the freezing embryo as well.
