To evaluate the effect of utilization of corn distillers dried grains with soluble (DDGS) as partial alternative of soybean meal on broiler chicks performance, 96 chicks of ROSS 308 were used and they fed diets with 0, 15, 30 and 45 % DDGS in grower and finisher diets (Control group, T2, T3 and T4, respectively) from 8 to 42 days of age. At the end of the experiment (42 days of age), body weight of the chickens in groups T2 and T3 were (2897.33g and 2967.67 g, respectively) and they were significantly heavier (P<0.05) as comparison with chickens in control group (2537.33 g). Also, weight gain at 36-42 days of age, in groups T2, T3 and T4 (587.33g, 569.33g and 615.33, respectively) were significantly higher (P<0.05) than chickens in control group (444.00g). While, feed intake in T2 was (1250.00g) at the end of the experiment and significantly increased as compared to the control group which was (956.33g). Although, feed conversion ratio at 42 day of age in T1 was (2.16 g) and it is higher in comparison with T4 which was (1.90g). At the end of the experiment, carcass, breast and thigh weights, in the chickens of group T3 recorded significantly (P<0.05) high weight as compared with chickens in control group. While, there were no significant differences among the groups in wing weight and weight of other organs in this experiment. Protein percentage in breast meat at the end of the experiment in group T4 (23.93%) were significantly higher (P<0.05) as compared with chickens in control group (21.17%).
