PRINCirLES OF FEEDING FARM ANIMALS 



Over two-thirds of the corn crop of the United States is 

 produced by the following states : Illinois, Iowa, Kansas, 

 Nebraska, Missouri, Indiana, and Ohio. 

 Consequently, these states are often spoken 

 of as '' the corn-belt." Although corn is 

 grown to a considerable extent in many other 

 states, in no instance is the production larger 

 than the consumption. In many states little 

 or no corn is grown. Over 90 per cent of 

 the total corn crop of the United States is 

 produced by 21 states. 



There are two races of corn of special 

 interest to the stock feeder, viz., flint corn 

 and dent corn. FUnt corn is harder, smaller, 

 and yields less than dent corn. It is es- 

 pecially adapted to 

 localities with a sea- 

 son too short to pro- 

 duce the dent varie- 

 ties. It is grown 

 largely in the north- 

 ern and eastern parts 

 of the United States. 

 In the corn-belt, dent corn is practi- 

 cally the only race of corn used for 

 stock feeding, o^ving to the larger 

 yield. There is little difference in 

 the chemical composition and feed- 

 ing value of flint and dent corn. 



Corn may be of varied colors, yellow and white being the 

 most common. It is often said that yellow corn has a
