The Utilization of Wheat and Wheat By-Products in Feeding Young Chickens : V. Protein Supplements for Ground Wheat

Abstract

ACCORDING to the work of McCollum, et al (1916), the wheat kernel contains protein of suitable quality to promote nearly normal growth in rats, when supplemented with adequate salts and the fat-soluble vitamin, although reproduction was not normal until the protein was modified by the addition of casein.Osborne and Mendel (1919) concluded that, for maintenance, the proteins of the wheat kernel are nearly as good as casein or edestin, and are superior to gliadin, which is deficient in certain essential amino acids, but they are supplemented by glutenin. Gliadin and glutenin are the two principal proteins of wheat, which also contains small amounts of globulin, albumin, and proteose. Osborne and Mendel confirmed the findings of McCollum, that the entire protein of wheat is adequate for normal growth in rats, if eaten in sufficient amounts (whole wheat 92 percent or 10 percent wheat protein in the ration); but according to .
