The lowest feed conversion ratio of 2.3 kg/kg was recorded in T2 and T5 treatments, followed by 2.4 kg/kg in T6, 2.5 kg/kg in T3 and T4, and 2.6 kg/kg in T7 and T8. Lower feed conversion ratio in experimental treatments shows that addition of garlic, black pepper and hot red pepper and their mixture have positive influence on feed utilization and efficiency
