摘要：In the self-selections of inorganic salts, selection patterns varied markedly individually as were found in organic nutrients. A constant selection pattern was not found in the mean selections of the rats throughout the experiment, and then individual differences were noted. However, mean selection of 5 days of individual animal showed that each animal maintained a constant selection in the individual manner throughout the experiment. Larger fluctuations were observed among animals in th selections of inorganic salts as compared with those of organic nutrients.
