The purified synthetic diet shown in Table 1 was given to the day-old White Leghorn male chicks for 3 weeks in the electrically heated battery. The growth of chicks was very poor and various symptoms such as excitability, ataxia and prostration were observed. The growth was however, normal when the amount of vitamins was more than 1.5 times of the original dosage. Comparing the amounts of vitamins given in this experiment with those used by various investigators in the United States and taking the vitamin requirement recommended by National Research Council, U.S.A. into consideration, it seems true that vitamin requirement of Japanese chicks is higher than that of American chicks. Pyridoxine may be one of such vitamins required more. Supplementation of arginine and glycine was effective in increasing the growth rate, but the effect of increase in amount of vitamins was much more remarkable. It may be reasonable to determine the vitamin requirement first and then to study further the amino acids and others.
