To assess the effect of insoluble dietary fibre sources and level on growth performance and nutrient utilization, a feeding experiment was conducted on day old broiler chicks (n=270) for 35 days under 2×3 factorial arrangement. The day old chicks were randomly divided in to six groups (T1 to T6) of 45 each. Two sources of dietary fibre (soy hull or rice husk) were used at 0, 2 or 4 % level and each dietary level have the three replicates of 15 chicks each. The T1, T2 and T3 were allocated to soy hull group, wherein T4, T5 and T6 were fed rice husk at 0, 2 and 4% dietary level, respectively. Inclusion of rice husk (4% level) significantly (P<0.05) improved the feed intake and body weight of chicks at 35th d. Although, source of fiber did not affect the feed intake and FCR both source of fiber at 4% level had higher (p<0.05) feed intake. The DM metabolizability was higher (P<0.05) in control group of chicks fed diet with soy hull, whereas metabolizability of EE was significantly (P<0.05) higher in control group of chicks fed rice husk. The metabolizability of EE was significantly (P<0.05) better in rice husk group as compared to soy hull. The energy and Ca retention were similar among the groups, but per cent P retention was higher (P<0.05) in chicks of control group (T1). It may be concluded that the inclusion of 2 and 4% level of coarse insoluble fiber sources such as rice husk (42.68%CF) and soy hull (27.25% CF) in diets had no comparative adverse effect on overall performance of broiler birds. Inclusion of rice husk in broiler finisher diet at 4% level resulted in improved performance of broiler birds.
