| Research Abstract |
It was shown in this study that feeding of indigestible sugarsfuructooligosaccharide and mannitol which escape gastrointestinal digestion improved the utilization of dietary protein and this should be resulted from the following effects: Indigestible sugars stimulated cecal bacterial proliferation using blood urea as a nitrogen source and the bacterial protein increased in the cecum was ingested by rabbits as nutritional quality protein. These findings must be put to practical use for the improvementof production efficiency and for reduction of nitrogen excretion.
