Albino rats were fed on a basal diet composed of yellow corn meal, gluten powder, salt mixture, and vitamin mixture.When L-or DL-lysine was supplimented to the basal diet, the growth of the animals was markedly stimulated and the blood hemoglobin level was raised to normal value.Growth of bone tissue was also improved decidedly. D-Lysine was also effective, althogh in less extent. This might be due to that the D-amino acid preparation contained L-form remaining unremoved.Excessive addition of L-lysine to the basal diet gave no harmful effect to the animals.
