The influence of growth rate on body composition and of cut up chicken parts relative to eviscerated carcass weightwas determined. 380 male and 390 female chickens (Lohman) were divided into three groups for each sex by body weight (large,weight groups were 2,826, 2,584, and 2,387 for females, and 3,399, 3,078, and 2,638 g for males. Average body weights of thregroups by shank length were 2,708, 2,526, and 2,577 for females, and 3,308, 3,096, and 2,789 g for males. Correlation betweenshank length and body weight for females was 0.44 and for males was 0.84. Proportions of body components by weight were notsignificantly different for females and males. Proportions of blood (3.51%, females, 3.95%, males), of head and shank (5.54%,P<0.05). Proportions of blood,feathers, head and shank, inedible viscera and edible viscera by shank length were not significantly diferent between sexes butproportion of eviscerated carcass weight was lower in the short shank length group (P<0.05). Percentages of cut up parts to evis-cerated carcass weight for females and males were 35.8 and 36.4 for thigh-drumstick, 28.5 and 28.5 for breast, 11.7 and 11.7 forP<0.05). Percentages ofcut up parts to eviscerated carcass weight did not difer among body weight groups in females. Percentage for necks was higher inlarge (7.91%) than in small weight group (7.17%). Percentage for wings was higher in small (12.15%) than in large weight group(11.43%) in males. Percentages of eviscerated carcass weight for wings in males and for thigh-drumsticks in females were sig-nificantly different among shank length groups (P<0.05).
