Oats apparently possess a stimulating substance. Johnston, 

 believing that he had separated this active principle in 1885, 

 called it avenine. This principle, according to Sanson, is 

 contained in the hulls While it exerts its effect upon horses, 

 causing them to show metal, yet close observation has appar- 

 ently not been made to determine if any stimulating effect 

 comes from feeding oats to poultry. 



The by-products in the manufacture of oatmeal is oat hulls, 

 which are of low feeding value and can hardly be recommended 

 in poultry feeding. 



From these mills there may be obtained oat dust, which ranks 

 close to the grain in composition and could be used in dry 

 mash. Oat shorts, another good constituent for mash, is 

 higher in nutrients, containing 12.5 per cent, protein, 46.9 

 per cent, carbohydrates, and 2.8 per cent. fat. 



The form in which oats is most often fed is as follows — 

 whole oats, either clipped or undipped, constitute a part of 

 the morning and evening scratch feed; rolled oats and pin- 

 head oats for baby chicks; hulled oats for broiler-size chicks; 

 sprouted oats for succulent feed. 



Rice has not come into general use as a poultry feed. It is 

 low in protein and fat, as can be seen by referring to the table 

 of digestibihty of food nutrients, but on the other hand it is 

 rather high in carbohydrates, of which nutrient there is 72.2 

 per cent, digestible. 



There are some by-products of rice of which rice hulls is one. 

 This by-product consists of cellulose, which is very hard, 

 woody, and cannot be recommended for poultryfeeding. Rice 

 bran consists of the outer portion of the rice grain with some 

 of the germ. It contains 5.3 per cent, protein, .3 per cent, 

 fat, and 45.1 per cent, carbohydrates. 



Another by-product is rice pohsh, which is a dust-like 

 powder rich in nutrients. It could well form a part of the 

 dry mash in localities where it can be purchased at a reason- 

 able price. It contains 9.0 per cent, protein, 6.5 per cent, fat, 

 and 56.4 per cent, digestible carbohydrates. 



Buckwheat is extensively grown in some localities and, where 

 it can be purchased at a reasonable price, may prove profitable 

 in the ration.
