A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloy and cinnamon powder on growth performance, carcass traits in commercial broilers. A total of 120, day-old broiler chicks were divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T₁ (control) were fed basal diet whereas in treatment group T₂, T_3, T_4, T₅ and T₆, basal diet was incorporated with 1% giloy, 2% giloy, 1% cinnamon, 2% cinnamon and combination of 1% giloy and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P≤0.05) higher in T₃ incorporated with 2% giloy. The feed conversion ratio was significantly (P≤0.05) improved in broiler chicks fed diet incorporated with 1% giloy (T₂). The performance index was significantly better in T₂ and T₃ compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T₂ and T₆ compared to other groups. Performance index was significantly higher in T₂ incorporated with 1% giloy. During the whole experimental period (0-42 days), incorporation of 1% giloy improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T₁, T₂, T₃, T₄, T₅ and T₆ were 1408.6, 1580.0, 1540.1, 1517.0, 1474.2 and 1551.0, respectively. The results of growth performance of broilers on incorporation of 1% giloy and 1% cinnamon in combination are also beneficial. Significant (P≤0.05) increase in dressing percentage with or without giblet was observed in T₂ and T₅, respectively. It is concluded that 1% giloy in the diet of broilers has better results in terms of growth, dressing percentage. The incorporation of 1% giloy and 1% cinnamon in combination in the basal diet of broilers could be recommended for producing designer meat.
