Abstract
A study was conducted in Arni ducklings to optimize the dietary crude protein and metabolizable energy levels to assess their production performance, carcass traits, meat quality and economics. The experimental period was divided into starter (0-3weeks) and finisher (4-12 weeks) phases. A total of 224 day old straight run ducklings were randomly allotted to 1 control and 6 combination of CP and ME (3 x 2 factorial) as treatment diets (4 replicate; 8 ducks per replicate). During starter period body weight, ADG, CP intake, CP conversion, caloric intake and caloric conversion were not influenced by dietary treatments, but during finisher period group T3 (18% CP and 2800 kcal/kg ME) had significantly (P < 0.05) higher body weight and ADG. Ducks had
significant (P < 0.01) difference in CP intake and CP conversion at 20% level during finisher period. Different dietary treatments (CP, ME and CP x ME) had no effects on feed intake and FCR of ducks from 1-12 weeks of age. Dietary treatments had non-significant effect on caloric intake and conversion during starter and finisher period. Significantly (P < 0.01) highest yield in wings and meat bone ratio were observed in T1 and T3, respectively. Dietary protein and energy levels had non-significant effects on proximate composition, pH and sensory evaluation of meat, but had significant (P < 0.01) effect on cholesterol level of meat. Haematology and serum biochemical parameters were not influenced by dietary protein and energy levels except serum uric acid, which had significant (P < 0.01) effect by dietary treatment groups. At the end of 12th week, T3 had the highest BCR of 1.04 among the treatment groups.
