often fed to poultry to the exclusion of all other grains. 

 This is poor policy, for it will not conduce to good egg pro- 

 duction. Corn is not a well balanced ration. It averages 

 70 per cent of carbohydrates, which is too high a carbohydrate 

 content to be fed exclusively, while the protein content is 

 small. Four kinds of corn are sometimes used for feed; 

 these are dent, flint, sweet, and pop corn (Fig. 125). Dent 

 and flint are most common, 

 while the two latter are in 

 great demand for other pur- 

 poses. Corn may be fed 

 either whole, cracked, or 

 ground up into meal. When 

 whole or cracked it is usually 

 fed in the litter; when as 

 corn meal, in the mashes.

Wheat and Its Products. 



Wheat is the best exclusive 



feed for birds. It is palata- 



ble, highly nutritious, can be 



raised easily, and is relatively 



cheap (Fig. 126). It contains 



71 per cent of carbohydrates, 



while the protein content is 



much higher than in corn. enlarged 



There are two kinds of wheat, winter and spring, winter 



wheat being the best. Wheat is used quite extensively in 



the scratching rations for poultry. 



Bran and Middlings. These are two by-products from the 

 manufacture of wheat flour. They contain about 15 per cent 

 of protein and 55 per cent of carbohydrates. They consist
