Abstract
Rice bran (RB) is a valuable feed-stuff because it is rich in the B vitamins, fat and protein contents when compared with other cereal grains (Wang et al., 1997). However, it has a high content of fiber, that is rich in the hemicelloses containing highly branched arabinoxylans (Annison et al, 1995).
RB is used largely as animal feed. Only a limited amount of RB is currently being used for food or oil extraction (Takano, 1993). Studies to improve the nutritive value of RB by feed enzymes are limited (Farrell, 1994). Nevertheless, RB having a high content of arabinoxylans (non-starch polysaccharides) may respond to enzymes that are able to hydrolyse this complex carbohydrate. Also, the enzymes supplementation could improve the digestion efficiency by decreasing’ viscosity of intestinal contents and increasing the carbohydrates digestibility before the caecum of rabbit which could avoid its effect on the diarrhea, as suggested by Sequeira etal, (2000).
