The Utilization of Wheat and Wheat By-products in Feeding Young Chickens : III. Ground Wheat, Bran and Middlings as Sources of the Antineuritic Vitamin B

Abstract

McCOLLUM et al (1916), as well as Osborne and Mendel (1919), showed that 15 percent of wheat in the diet was sufficient to prevent polyneuritis in rats, provided these animals ingested enough wheat. Hunt (1928) found that 15 percent of either wheat or corn supplemented with autoclaved yeast gave growth in rats; and he believed cereals supplied plenty of the antineuritic vitamin when fed at a 15 percent level. Hetler et al (1931) reported that 15 percent of either wheat or corn was not enough to prevent polyneuritis and death in rats, but 25 percent of these cereals provided sufficient antineuritic vitamin. Bell and Mendel (1922) reported that the germ, which constitutes about 2 percent of the whole wheat kernel, contains only one-sixth of the vitamin B content of the wheat kernel, and standard wheat middlings contained 40 percent of the total vitamin B of wheat, while bran contained 24 .
