摘　　要：The present study was conducted to explore ways of JIVET research on Texel sheep,and to provide technical support for the improvement of the JIVET technology system for research on Texel sheep.Superovulation was conducted on 4-8-week old Texel sheep,and in-vivo ovum collection,in-vitro oocyte maturation and fertilization,and fertilized-embryo culture and transplantation were adopted to perform JIVET research on Texel sheep.The results showed that 296 available oocytes were obtained at an average of 74 oocytes per sheep;205 fertilized eggs were obtained at the 2-4 cell stage at an average of 51.25 eggs per sheep and a cleavage rate of 69.26%;and 66 of the fertilized eggs were transplanted to 11 receptor sheep.Six sheep were conceived at a conception rate of 54.55%,and 11 lambs were born.These results indicated that the present test could be used as a method for the study of JIVET technique on Texel sheep.
