초록
The effects of dietary cellulose to utilize the intake nutrients in the albino rats were investigated by the two consecutive experiments in this study. The author wanted to observe the effects of the age of animals and different level of dietary cellulose, high and low in the first experiment and the effects of dietary cellulose from three different sources, rice bran, vegetable and pure-cellulose at high level in the second experiment. The results were summarized as follows. (1) The obvious effect of dietary cellulose caused to increase feces weight. Consequently apparent digestibilities of intake nutrients in the diet decreased. It was noteworthy that fecal glucose excretion was significantly affected by cellulose intake. Since three nutrients, protein, fat and carbohydrate serve as energy sources in the body, this result can be interpreted to be lowered in the efficiency of energy utilization out of intake from the diet. (2) The nutrients loss due to dietary cellulose resulted in reduction of skeletal muscle and bone weights which lead eventually to affect in reduction of body weight. (3) The effects of dietary cellulose showed differently according to the amount of cellulose ingested, dietary nutrients composition, the kinds of dietary cellulose supplemented and the age of experimental animals. When the intake diet was proportionately imbalanced in three different energy sources, carbohydrate, fat and protein, the cellulose intake was adversely affected in the utilization of the nutrients in the body. Cellulose from rice bran decreased body weight gain, cellulose from vegetable maintained medium level in body weight and pure-cellulose increased body weight. Growing rats showed more sensitive effects of cellulose tolerance in the body than grown rats in every concerns of this experiment.
