abstract
A study was conducted to investigate carcass traits and production efficiency of broiler chicken. 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.
