Harmful Effects of Oats and Oatmeal. N. D. Kay, Poultry, May 10, 1930.

Oats contain an anti-vitamin. So far as known anti-vitamins occur only in association with vitamins. We must carefully investigate, not only the vitamin content, but also the possible danger of the anti-vitamins. Oats and oatmeal contains an anti-vitamin which is believed to be a potente source of trouble in chicken feeding. It is an anti-substance to the fat-soluble vitamin D. When oat-meal is used a g.reat deal of other valuable vitamin D food is rendered valueless. These facts explain the lamentably large number of cases of bone disease in Scotland, where they spoil good milk with the proverbial Scotch breakfast of oatmeal. It also explains a great deal of the poultry-leg weakness and kindred evils.
