Abstract

Apparent digestibility coefficients (ADC) of starch and calcium (Ca) and phosphorus (P) apparent availability were evaluated in five cereal grain products and by-products (corn, wheat meal, rice grain, rice bran and sorghum) for Nile tilapia. Chromic oxide was used as an external digestibility marker. The highest Ca and P apparent availability, respectively, were obtained for rice grain (43.03 and 64.79%), sorghum (39.89 and 58.09%) and corn (22.18 and 19.48%), while rice bran (-31.49 and 3.25%) and wheat meal (5.80 and 1.18%) showed the lowest values. Starch digestibility varied between 99.45 and 95.59% among the evaluated ingredients. This high ADC of starch observed in this study confirms that Nile tilapia is able to efficiently digest and utilize complex carbohydrates.
