The aim of the study was to investigate the effect of feeding broiler chicks on diets containing two different levels of Moringa Oleifera leaf meal (MOLM) on productive performance, and blood constituents. A total 180, day-old unsexed Cobb 500 broiler chicks. The birds were randomly assigned into three different groups; each group was subdivided into three replicates
(20 birds each). Group I served as control, and fed the basal diet only. Group II was fed the basal diet fortified 0.5% MOLM. Group III fed the basal diet with 1% MOLM. The results showed that, the birds that received 0.5% (MOLM) leaves on the top of the diet showed a significant (P ≤0.05) improvement on overall FCR with significant decrease in total feed consumption than control group however, however birds that received 1% (MOLM) showed a significant (P ≤0.05) improvement on final body weight development, average body weight gain and FCR with no significant difference in feed intake than control group. In addition to, blood indices showed that, that birds which fed on 0.5% MOLM had a significant decrease (P ≤0.05) in total cholesterol, triglycerides, LDL than control but group fed on 1% MOLM showed a significant decrease liver enzymes activity as (ALT and AST) beside to total cholesterol, triglycerides, LDL and a significant increase in HDL, while two treated group showed a significant increase in total protein while bird fed on 1% MOLM showed a significant increase in Globulin portion. We safely concluded that dietary fortification of MOLM has a positive effect on broiler performance and blood constituent
