Recent era has witnessed a growing interest in scientific community for utilising phytogenic mixture due to their novel attributes of improving performance of broilers. However, the search of economical phytogenic mixture is continuous. This experiment was formulated to study the effect of dietary supplementation of phytogenic mixture containing Nigella sativa, Allium sativum and Ocimum sanctum (1:1:1 ratio) in broilers. For this research, three comparable groups were formed viz. Control (no supplementation), T1 (supplementation @0.25% of feed) and T2 (supplementation @0.50% of feed) and this experiment lasted for 28 days. A total of 48 Cobb 400 broiler chicks were distributed randomly into three groups and each group contained 16 broiler chicks of same body weight. Statistical analysis of data revealed that T1 and T2 group had significantly higher overall body weight (P<0.001), feed conversion ratio (P<0.001) and feed conversion efficiency (P<0.001) than control group. However, T1 and T2 groups differed non-significantly (P>0.05). However, there was no significant difference in feed intake across all the groups. Economic analysis of production of broilers under three different feeding regimes revealed that T1 and T2 group broilers performed better than control group. Therefore, based on the findings of this study, it may be concluded that dietary supplementation of phytogenic mixture containing Nigella sativa, Allium sativum and Ocimum sanctum (1:1:1 ratio) @0.25% may economically improve the performance of broilers.

Highlights

• We studied the effect of phytogenic mixture on growth and economics of broilers.
• Phytogenic mixture had Nigella sativa, Allium sativum and Ocimum sanctum (1:1:1).
• Phytogenic mixture improved overall growth performance of broilers.
