The experiment was conducted for a period of 35 days on 135 birds divided in to three different treatment groups of 45 birds each T1 group which served as control were fed only as basal ration. Birds in T2 group were fed basal ration with MOALE (90 ml/L drinking water) and T3 group were offered basal ration with ascorbic acid (15 mg/L drinking water). The Carcass characteristics of treatment on relative weight of liver, heart, gizzard, intestine, spleen, bursa, giblet percentage, dressing percentage and eviscerated percentage in broiler chicken were shown non-significant (P>0.05) changes where as relative weight of abdominal fat was significantly differed (P<0.01) between the treatment groups. The production economics of broiler chicken was measured and found that water supplementation of MOALE and ascorbic acid in bird, reduced production cost by improving live weight gain and profit per kg live weight was maximum in MOALE supplemented group followed by ascorbic acid group and least profit was noted in control group. Keywords: carcass trait, abdominal fat, production efficiency, ascorbic acid Introduction Poultry sector plays important role in minimizing the protein and calorie deficiency of large human population of our country. Moringa oleifera is nutrient rich high nutritional value species. Hence, supplementation of ascorbic acid and Moringa tree leaf extract could be a possible to improve the carcass trait by reducing the stress of broiler birds with quality product production. This experiment was therefore, conducted to study the moringa oleifera aquous leaf extract and ascorbic acid on carcass characteristics and production efficiency of broiler chicken. (Onunkwo and George 2015) [7] studied to evaluate the effects of Moringa oleifera leaf meal on growth performance and carcass characteristics of boiler chicks and found that significant difference (P<0.05) in organ weights (wings, shank, drumsticks, kidney, liver, gizzard) and cut parts between the experimental and control groups and suggest that Moringa oleifera leaf meal can replace protein source (soyabean and groundnut cake) up to 10% in broiler diets without any adverse effects on growth and carcass qualities which could marginally reduce feed cost in broiler production. (Gadzirayi et al., 2012) [4] reported that there was significant difference on carcass yield between the different treatments of birds fed on different inclusion level of MOLM and also carcass parts, liver, head, neck, wing, back, thighs, shanks, breast, gizzard and lung, were weighed and exposed to significant tests. (Aderinola et al., 2013) [2] worked on the utilization of Moringa oleifera leaf as feed supplement in broiler diets and they observed that cholesterol levels and abdominal fat reduced with increased MOL inclusion in the diets of broiler birds (Cui et al., 2018) [3] studied on dietary supplementation of Moringa oleifera leaf on performance, meat quality and oxidative stability of meat in broiler chicken and they found that increased feed conversion ratio and decreased abdominal fat linearly in response to the supplementation of MOL in diets. Materials and Methods The study was planned to see the comparative effect of water supplementation of Moringa oleifera aqueous leaf extract (MOALE) and ascorbic acid as an antioxidant sources in broiler
