This study was done in order to observe the nutritional effect of the rice diet supplemented with fish flour every one to four days. The protein, lipid and cholesterol contents in liver, serum protein and cholesterol values and hemoglobin and hematocrit values were measured. The animals used for the experiment were adult female albino rats from a pure strain, weighing 239-297g. The animals were divided into five diet groups: the standard diet (control group), the rice diet supplemented with fish flour once every other day group (A group), every two days (B group), every three days (C group) and every four days (D group). Each animal group was redivided into four groups by the length of feeding of each diet; the feeding groups were for fifteen days, thirty days, forty-five days and sixty days. The results obtained are summarized as follows: 1. The protein contents in the livr of the A and the B groups were similar to the value of the control. After feeding of this diet for fourty-five days they were slightly decreased, and those of the C and the D groups were generally decreased, compared with the control group. 2. The protein values in the serum showed no maked change compared with the control group and showed no change with either the type of diet or length of time this diet was given. 3. The lipid contents in the liver of the A and the B groups were increased, compared with the control group, up to thirty days but after forty-five days they were decreased. Those of the C and the D groups were usually increased, compared with the control group regardless of the length of feeding. 4. The cholesterol contents in the liver of each diet group were slightly decreased, compared with the control group for the duration of the study. 5. The hemoglobin and hematocrit values of each diet group (except the A group) were slightly decreased at fifteen days after the feeding of each diet. From the above results it is suggested that the nutritional effect of the low protein diet was most improved by a fish flour supplement given once every other day. It seems likely that shorter the interval of the periodical supplement, greater the nutritional effect.
