In order to investigate an effect of a cellulosis (fibrous material) on the biological utilization of protein, diets contained 15.0% of earth worm cake and 3.0, 5.0, 10.0, 17.0 and 24.0% of rice straw meal, respectively, were prepared. And diets contained protein-free (basal) and 15.0% of fish meal or milk casein, respectively, which also included 17.0% of the rice straw meal, were prepared. Hatched single comb White Leghorn male chicks were fed with a commercial diet for the first 10 days, basal diet for the next 6 days and experimental diets for the subsequent 6 days. During 6 days of experimental feeding, protein efficiency ratio (PER), net protein ratio (NPR), digestibility, biological value (BV) and net protein utilization (NPU) of the each worm cake protein were observed
