Polished rice powder with addition of salt mixture and vitamin mixture was used as the basal diet.Supplimentation with tryptophane and or lysine did not improve the growth of rats. When DL-threonin was added to the basal diet with L-lysine the growth of the animals was conspicuously stimulated. There was no detectable difference in blood hemoglobin levels among the animal groups fed on the different diets. Growth experiments with various amounts of added threonine to the basal diet supplimented with lysine revealed that addition of as little as 0.025% threonine stimulated the growth distinctly.
