​Effect of Neem (Azadirachta indica) Leaves Powder and Cinnamon (Cinnamomum zeylanicum) Oil on Growth Performance of Broiler Chickens

Background: This study was conducted to assess the effect of neem (Azadirachta indica) leaves powder (NLP) and cinnamon (Cinnamomum zeylanicum) oil (CNO) on growth performance broiler chickens. Methods: Four hundred twenty day old commercial Vencobb 400 chicks were randomly distributed into 6 groups 7 replicates each. Dietary treatments were; T0 (control: basal diet), T1 (basal diet + 2 g NLP/kg), T2 4 T3 100 mg CNO/kg), T4 200 CNO/kg) T5 NLP/kg CNO/kg). Result: Birds supplemented showed improved average daily gain (ADG), better FCR efficiency index. Overall ADG significantly high in than other groups. The groups, which fed CNO mg/kg a combination (100 mg/kg) NLP (2 g/kg), respectively, control as well It can be concluded that dietary supplementation along with g/kg) has potential improve However, recommended chickens an alternative promoter for production optimum health status.
