Abstract
The 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%. Once the birds started to lay, all of them were fed the same layer diet containing 5.8% CF. The result was found that 8% of CF seemed to be optimum in growing chickens. The higher level, at 11%, caused adversed effects on feed efficiency and body weight gain of growers although there were no adverse effects on performances of layers.
