Abstract: From 1987 to 1993，16 male Giant Pandas fed in our country mated up 31 female Giant Pandas for 108 times，and gave birth 45 young at thirty five litters.Seven of the 16 male Giant Pandas had the ability of natural mating，and the conception rate was 68.00%.Nine of them didn’t have the ability of natural mating，we can only collect the semina by electron injector from them，but three Giant Pandas semina reached the aim of farrowing effect by the artificial fertilization，and the farrowing rate was 19.12%．Around the natural mating，the conception and farrowing rate was higher.Under the artifieial feeding，only three Giant Pandas had the ability of natural mating，and one Giant Pandas semina collected by artificial electron injector can reach the farrowing effect．Under the artificial feeding,the natural mating age is between 6-21 years in male Giant Pandas，5-12 the twin are more．There are differences in the mating and farrowing effect due to the different birth place of Giant Pandas．
