Use of Monosodium Glutamate for Improving the Palatability of Amino Acid Rations. ∗

Abstract

Summary

A synthetic ration in which all of the nitrogen is furnished as free amino acids is not as palatable to the mouse as one containing casein. The inferior palatability results in less food consumption during the first 3 to 7 days and consequently poorer growth. When the initial lag period is diminished or eliminated by the addition of 1% of monosodium glutamate to the ration, the final weights of the mice are more consistent and approach more closely those of the animals fed a ration containing casein.
