| The profitability of any chicken industry related to increasing the production. Therefore, most of the breeders are looking for some traits that can measure in early age to select the best birds. However, several studies were conducted on ruminates, but there are few studies in the broiler. Therefore, the current study aimed to investigate the effect of sex on some of body measurements (body length (BL), shear bone length (SBL), body circumstance (BC), chest width (CW), leg length (LL), and

... igh circumstance (TC) along with the estimation of the correlation coefficients among these measurements and body weight to evaluate the body measurements as predictors of final body weight using all possible regression procedure. A total of 60 chicks Ross 308 broilers (30 male and 30 female) were used. Results indicated that the effect of sex was not significant on all body measurements at the 1 st and 2 nd week except the body circumstance (BC) at the 2 nd week. Whereas, the effect of age was significant (P<0.05) on the SBL, BC, CW at age of 3 rd , 4 th and 5 th week. All of the correlation coefficients among body measurements were significant (P< 0.05). The R 2 estimated by all possible regressions procedure to predict the final weight showed that The R 2 increased with increasing the number of predictors and with advanced age and ranged 0.24-0.51, 0.41-0,76, and 0.63-0.89 at 1 st , 2 nd , and 3 rd weeks respectively. The results of the present study showed that the correlations between the body measurements and body weight are significant.
