Abstract: Body weight，body length，wither height，heart girth, abdominal circumference, cannon bone circumference of 165 Chinese Simmental were measured.Estimating the body weight by using stepwise regression,and compared with the measured body weight.The formula of estimated body weight of Chinese Simmental has been received in this paper.F and t test of the formula indicates that the predicted and actual value had no significant difference，and the related coefficient is 0.952.

Key words: body measurements; stepwise regression; estimating body weight; Chinese Simmental
