[ Method] With Boer goats from embryo transplant as the tested animals and natural breeding Boer goats born in the same period as CK, the weight of Boer goats at birth and at the age of 1,3 and 6 months as well as the body size at the age of 3 and 6 months were investigated in this study, while their health conditions were also observed and recorded. [ Result] Under the normal feeding conditions, Boer goats from embryo transplant developed well at early stage, and their meat-using body type were also obvious. The average birth weight of bucks was （4.25±0.95） kg, and that of does was （3.74±0.10） kg. The average weight of bucks at the age of 6 months was （31.90 ±0.74） kg and that of was （25.90 ±0.67） kg. The daily gains of bucks and ewes from birth to 6 months of age were 153.64 and 123.11 g respectively, while their body length, body height and chest circumference increased obviously, and there was no significant difference in body weight or body size between them and natural breeding goats. [ Condusioa] The study lays a foundation for further studies on the breedinq and utilization of Boer noats from embryo transplant at early staae.展开更多
