The research was carried out on 300 CP707 broiler chicken from 1-49 days old, divided into 2 groups (experiment and control). A group consist of 5 subgroups, and 30 chicken per each subgroup (30 x 5 = 150 chickens/ group). Control group was fed by mixed feed of CP without supplementing addictive 528s, and experiment group was fed by mixed feed of CP with supplementing addictive 528s, dose was 1.25 g/kg feed. Results showed that chickens in the experimental groups supplemented 528s always had average live weight gain higher than the control, and lower FCR than the control. At 7 weeks of age, the average live weight and FCR of the experiment group respectively 3077.93 g and 1.91 kg/kg, while the control group respectively 2930.54 g and 1.97 kg/kg, and 95.21 percent and 103.14 percent compared. to the experiment group.
