摘要：Self-selections of starch, olive oil, casein, cod-liver oil and dry yeast in the albino rats were observed. Summarizing results obtained in the present experiment, individual differences among feeding patterns of rats were noted but periodical fluctuations were small within individual rats. These findings seem to show the feeding habit, but rather they look like the outcomes of preferences of the individual subjects. Discussing the results as to inter-nutrients relations, each subject ingested 11-61% of carbohydrate, 10-31% of fat, 14-45% of protein, 0-2.4% of cod-liver oil and 1.3-4.2% of dry yeast in relation to total ingestion. So that the ratio of ingestion in the present result fairly corresponds to the standard diet of rats. Therefore, it may not be conceivable that the deficiencies of nutrients are elicited by the self-selections of diets. However, further investigations are necessary to confirm whether the present feeding patterns coincide with physiological needs of animals and then hygienically reasonable for each animal or not.
