This experiment was conducted to investigate the reasonable levels of energy and protein for the production of large broilers. A total of nine hundred sixty, day old broiler chickens (Ross) were randomly divided into six groups with four replicates of forty birds each. Experiments were factorial designed with 3,100, 3,000, and 3,030 kcal of ME/kg and 22, 21, and 21% CP for the first week; and 3,100, 3,035, and 3,050 kcal of ME/kg and 19, 19, and 18.5% CP for the second and third week; and 3,100, 3,175, and 3,100 kcal of ME/kg and 17, 18, and 17.5 CP for the fourth and fifth week; and 3,100, 3,175, and 3,250 kcal of ME/kg and 17, 17, and 18% CP for the sixth and seventh week. Body weight and feed conversion ratio were higher in T3 than the other treatments groups (p<0.05). Feed intake was higher in than males than females treatment group (p<0.05). No significant differences were observed in carcass percent and leg meats production rate was 22.5% in T1 treatment of male and female were 22.5% of the T5 treatment. In addition, 21.4% in females treated T4 and T6 treatment was 21.5%. Abdominal fat was higher in males than females. After seven weeks, the moisture content of litter did not differ among the treatments. In the experimental results, large male broilers at the end of the feeding in protein and energy levels should be increased. However, females did not suggest a need to increase.
