The study aimed to investigate the potential advantages of incorporating Moringa olifera leaves (MOLM) into broiler diets as a feed replacement of soyabean meal. A total number of 120 7-day-old Ross chicks were selected for the study. The birds were randomly divided into four treatment groups, each with 30 birds and three replicates with 10 chicks each, and fed on diets containing four levels of Moringa oleifera leaves 0, 2, 3, and 5% were substituted from soyabean meal). Growth performance, carcass traits, digestibility coefficient, some blood analyses, and economic efficiency were recorded. The results showed that, birds fed diet contained MOLM during starter and grower period, respectively recorded significantly (P≤0.05) the best body weight, body weight gain and feed conversion ratio compared with control diet. The results showed that the diet of Moringa oleifera leaves did not affect the digestion coefficient (%) of growing broilers. Except for the increase in nitrogen balance (NB%) with the addition of MOLM to diet. The findings demonstrated that dietary amounts of Moringa oleifera had no impact on the carcass characteristics of developing broilers. Also, on biochemical parameters, the findings revealed no statistically significant variation among the various treatments. Except for glucose, low density lipoprotein (LDL), and alanine transaminase (ALT), there were significant differences depending on the level of MOLM in the diet. Finally, these results suggest that including 3-5% Moringa oliefera leaves in the chick, feed can lead to higher economic efficiency and net revenue compared to not including it.
