CHAPTER X 



THE CEREAL BY-PRODUCTS 



The cereal by-products, as the name implies, consist of the 

 offal and residues of the cereal grains resulting from the 

 manufacture of flour, starch, meal, breakfast food, and other 

 products for human consumption. They usually contain 

 those parts of the grain which are high in crude fiber, crude 

 protein, and ash, and low in nitrogen-free extract. Inasmuch 

 as the ordinary farm-grown rations are usually high in car- 

 bohydrates and low in crude protein and mineral matter, 

 many of the cereal by-products are of considerable im- 

 portance to the stock feeder. 



CORN BY-PRODUCTS 



The by-products of corn are principally from the starch 

 and glucose factories, from the distilleries, and from the 

 hominy factories. The starch and glucose by-products 

 are gluten meal, gluten feed, corn bran, and com germ meal. 

 The distillery by-products are distillers' slops and distillers' 

 dried grains. The by-product from the manufacture of 

 hominy is hominy meal or hominy feed. 



In the manufacture of starch and glucose,^ the corn is 

 first soaked in a warm, very dilute solution of sulphurous acid. 

 It is then ground by being passed with water through mills
