Study aimed to investigate the optimum level of fiber in diets of replacement pullets. Rough rice bran was used as a source of dietary fiber. The trial was conducted in 2 experiments. Exp 1 was from 15 to 20 weeks of birds age while Exp 2 was from 10 to 34 weeks of birds age. Crude fiber (CF) content of diets during growing period, before 20 weeks of birds age, was 5, 8 or 11 percent. Once the birds started to lay, all of them were fed the same layer diet containing 5.8 percent CF. The result was found that 8 percent of CF seemed to be optimum in growing chickens. The higher level, at 11 percent, caused adversed effects on feed efficiency and body weight gain of growers although there were no adverse effects on performances of layers.
