The present study aimed at evaluating the apparent digestibility of rice bran, corn meal and cassava meal for grass carp (Ctenopharyngodon idella). The digestibility of nutrients of these plant-ingredients were determined using the indirect method with the incorporation of Cr2O3. Rice bran appeared to have a high digestibility of dry matter (80.3%), protein (87.9 %) and ash (97.4 %) for grass carp. Corn meal has also high digestibility of dry matter (88.9%), protein (84.9%) and ash (92.7%). There was no statistically significant difference when comparing the digestibility of protein and ash between rice bran and corn meal for grass carp. The dry matter, protein and minearl digestibility of cassava was 80.3%, 87.9% and 14.3%, respectively, and appeared to be inferior to rice bran or corn meal. Our results indicated that the grass carp digests rice bran and corn meal better than cassava meal.
