CHAPTER XV 



FEEDSTUFFS 



Corn. — ^There are two races of corn — namely, flint and dent, 

 and a third may be considered — namely, sweet corn. Corn is 

 high in starch content. In the flint corn most of the starch is 

 hard and corneous in character, which is easily demonstrated 

 by cutting a grain crosswise and examining it. In dent corn 

 the starch is floury in nature, except a small portion near the 

 exterior, which is hard and corneous. The corneous and floury 

 parts are chemically the same.

Corn may be of different colors, as white, yellow, red, and 

 blue striped. 



Yellow corn is objected to by some breeders of white plumage 

 birds, believing that it causes the brassy luster on the coat, 

 which shows most on the wing-bows and back. 



The grain of sweet corn is hard and wrinkly. The hard, 

 corneous character is due to shrinkage during the process of 

 maturing. Sweet corn contains more protein and fat than 

 flint or dent, but on the other hand it contains less digestible 

 carbohydrates.
