Abstract
    This study was carried out to determine the effect of feeding with various energy and protein ratio in the diets on the performance and carcass values of native chicken. The rations have six different combinations of energy and protein : PE1 (18% protein and 2800 kcal/kg energy; PE2 (18% protein and 3000 kcal/kg energy; PE3 (18% protein and 3200 kcal/kg energy; PE4 (20% protein and 2800 kcal/kg energy; PE5 (20% protein and 3000 kcal/kg energy; and PE6 (20% protein and 3200 kcal/kg energy; were fed to native chicken for 60 days period. The experiment consisted of 6 x 4 x 3 factorial design. Results indicated that no interactions were found between dietary energy and protein level. Different protein levels, in the diets have no significant differences (P > 0.05) on any parameter measured, whereas different dietary energy has significantly (P < 0.05) influenced on feed efficiency. It can be concluded that with adequate balance of calorie and protein, low energy and low protein combination in the diet could be fed to improve the performance of native chickens.

Key words: dietary energy, protein levels, performance, carcass, native chicken
