CHAPTER XIV 



CATTLE FOODS— COMMERCIAL FEEDING- 

 STUFFS 



The cereal grains and other seeds are the source of 

 a great variety of by-product feeding-stuffs which have 

 a large and widespread use, especially in the dairy sec- 

 tions of the United States. In the preparation of a 

 great variety of human foods and of other materials 

 important in industrial life, certain by-products are 

 obtained which represent particular parts or compounds 

 of the grain or seed. Whenever the methods of manu- 

 facture are such as not to injiu-e the palatableness or 

 healthfulness of these waste products, they may be 

 utilized as cattle foods. As a matter of fact, a large 

 proportion of our commercial feeding-stuffs is of this 

 general kind and because these materials differ greatly 

 in composition and nutritive value, the purchaser should 

 clearly understand their source and character. Changes 

 in methods and new manufactiu-ing enterprises are 

 constantly modifying 'the composition of old products 

 and introducing new ones, consequently the facts as 

 they exist at one time may not be applicable for a long 

 period. There is need therefore of constantly keeping 

 informed in regard to the various cattle foods found in 

 the markets, if they are to be economically purchased 

 and wisely used.
