    The present study was carried out to study the effect of dietary inclusion of Moringa oleifera leaf meal (MOLM) on performance of broilers in hot humid climate. Ross broilers of 180 numbers at day old were distributed randomly to six dietary groups each with five replicates of 6 birds each and were maintained under uniform managemental conditions. During the experiment, Moringa oleifera leaf meal was included at 0% (T1; negative control), control + Vit-E,Se,Vit-C(T2;positive control), 1.5% (T3), 3%(T4), 4.5% (T5) and 6% (T6) levels by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous as per BIS (2007) Chemical analysis indicated that MOLM contained 25.13% CP, 12.68% CF, 8.42% EE, 3.25% calcium and 0.49% phosphorus. Significantly (p<0.01) higher body weights were observed in birds fed with MOLM. The body weight gain was significantly higher (p<0.01) in 3.0% MOLM and lower in negative control. The overall feed intake decreased significantly (p<0.01) with increase in level of MOLM (0 to 6.0%) present in the diet compared with the control. While better (p<0.01) FCR was reported at 3.0% level of MOLM inclusion. Serum cholesterol was significantly decreased (p<0.01) and serum protein (p<0.05) and serum globulin were significantly (p<0.01) increased with increasing MOLM in diets whereas, albumin and A/G ratio were not affected by level of MOLM in diets. The haematological parameters of broilers revealed that inclusion of Moringa leaf meal from 0 to 6.0% in the diet had no effect (p>0.05) on PCV, Hb, RBC, WBC and H/L ratio and also on HI titers. The carcass traits like live weight, carcass weight and ready to cook yield were significantly (p<0.01) higher in birds fed with 3.0% MOLM group. On other hand, inclusion of MOLM from 0 to 6.0% in diet had no effect (p>0.05) on dressing percentage, liver heart, gizzard and giblet weights and proximate composition of meat The meat quality parameters of broilers revealed that inclusion of MOLM upto 6% level had no effect on pH, ERV, WHC and sensory evaluation of the meat, except colour of the meat. Colour of the meat significantly (p<0.01) decreased at 6.0% level of MOLM present in the diet. The feed cost / kg gain was lowest (p<0.01) in broilers fed with 3.0% MOLM as compared with other treatment groups. The study indicated that the feed cost /kg gain was Rs 58.13 (T1), 52.66 (T2), 51.17 (T3), 46.78 (T4), 49.75 (T5) and 50.05 (T6). It is concluded that MOLM can be safely incorporated up to 3% level in the diet without any adverse effect on performance of broilers.
