| Summary: | The aim of this study was to determine the basic of nutrient requirement and the performance of native chicken of grower phase (6 to 14 weeks) by free choice feeding system. Ninety-two day old chicks were randomly divided into 4 cages and 23 chicks each. The chicks fed by free choice feeding system with: corn meal, rice brain, soybean meal, fish meal, lime stone, vitamin premix available separately. The parameter collected were feed consumption, nutrient consumption (energy, crude protein, methionine, lysine, calcium, phosphor, crude fiber) and the performance of chicken (body weight and percentage of carcass). The result showed that feed consumption was 2684.36 g/bird/8 weeks; ME 2990.55 kcal/kg; crude protein 15.53%; methionine 0.02%; lysine 0.05%; Ca 1.60%; P 0.6%, and crude fiber 7.30%. The performancae of chicks on body weight at 14 weeks ws 659.23 g/bird; gain weight 436.95 g/bird/8 weeks; FCR 6.14; carcass weight 388.63 g; and carcass percentage 57.57%. It can be concluded that native chicken was able to fulfill nutirent requirement as same as white or brown layer nutrient requirements based on NRC (1994) except methionine and lysine.
