A total of 300 male broilers (Cobb 500) were fed with different levels of CDGS (0% - control, 5, 10, 15 and 20%) in starter (age 0 to 21 day) and grower (age 21 to 42 day) diets, and weight gains and feed intakes were recorded. All diets were formulated isocaloric and isonitrogenous which met or exceeded the NRC requirements. At the end of the experiment (42 day) eight birds from each treatment were slaughtered to measure the dressing percentage, carcass parts yield and fatty acid profile of breast meat (from the left carcass side). Birds fed 5% CDGS had better (p0.05) from control. There were no differences (p>0.05) in overall weight gain, feed intake, dressing percentages and carcass parts yields (% of carcass weight) among treatments. There were greater (p
