The Relative Biological Values of the Proteins in Cereal Grains

Abstract
The biological values of milled and whole cereal grains, fed at a 5% protein level, were determined by the Mitchell ('24b, '44) nitrogen balance method. The protein utilization for the milled cereal grains was as follows: Rice, 75.1; wheat, 60.0; rye, 63.1; and corn, 32.0. The findings for the whole cereal grains were: Rice, 80.0; wheat, 76.1; rye, 73.2; corn, 78.8; and rolled oats (oatmeal), 75.6.
