ABSTRACT
The 5 foods, apple, bran, cabbage, carrot and pear, were fed to rats as part of 5 diets each containing 2.5% neutral detergent fiber (NDF) and the effect on increasing dry stool weight (DSW) and the digestibility of dietary fiber (DF) components of the foods were studied. The results showed that DSW increased with increased NDF intake, cabbage being the most effective. The mean DSW of the test food groups was 2.27 times compared with non-fiberous controls. The SDW was correlated with intake of NDF and cellulose from analysis of individual variation. The regression equation was y =- 1.9040 + 3.5644X1 (NDF) + 3.5644X2 (cellulose).The digestion of DF components from carrot was the most complete, while hemice-llulose was 1.3 times as digestible as cellulose. Lignin was found to have an influence on DF breakdown. Increasing hemicellulose level might decrease the digestibility of cellulose. The variation of DF digestibility of di- fferent food may also be ascribed to the physical and biological properties of the food.
