| Abstract: | In order to make some suggestion for development and breeding selection of Gannan Tibetan sheep,multiple regression analysis between body weight and body size of sheep was made with 225 male and 290 female sheep randomly selected.The results showed that the optimized regression equation was as y=0.118x1+0.652x3+0.196x4(R=0.901,0.01
