Abstract
In this paper, an investigation was made to determine whether the carbohydrate in “konjac” powder is utilized as caloric source or not.
The pair feeding method was employed, based upon 30% “konjac” powder group and pairing 15% “konjac” powder group and rice starch group with it.
The results indicated that there was an apparent gain of body weight in “konjac” powder group.
As it was found that, by the feeding of “konjac” the proportion of the intestinal tract became larger than that of normal, then we proposed that the true growth of animals fed on “konjac” powder should be compared by the following formula:
True weight gain of animals= (Final body weight-final weight of digestive) - (Initial body
weight-initial weight of digestive tract)
In this calculation, the weight of digestive tract in the time of initial body weight was omitted, because it was regarded as the same weight in each rat at the beginning of experiment.
