The Millets. — Like the sorghums, the millets are grown 

 extensively in Asia and Africa as human food. They are 

 grown sometimes for their seed in the plains region of this 

 country, north of the areas best suited for the sorghums, 

 and are often used as catch-crops 

 in the corn-belt. Millet seed con- 

 tains more crude fiber and less 

 nitrogen-free extract and fat than 

 com. Its feeding value is consid- 

 erably less than that of corn. 



Rice is grown exclusively in the 

 South for human food. When dam- 

 aged or cheap in price it may be 

 used for stock-feeding with good 

 results. It is very high in carbo- 

 hydrates, but is low in protein and 

 fat. It has a feeding value equal 

 to that of corn, and when properly supplemented, may be 

 fed with good results to horses, cattle, sheep, or hogs if the 

 cost will permit.

THE LEGUME SEEDS 



The principal legume seeds used in stock feeding are 

 Canada field peas, cowpeas, soybeans, peanuts, and field 

 beans. 



The Canada field pea is grown principally in Canada, 

 northern United States, and in some of the Rocky Mountain 

 valleys where the spring and summer heat is not too great. 



The field pea is rich in protein and mineral matter. Com- 

 bined with other feedingstuffs, field peas are eminently fitted 

 as a feed for dairy cows and may make up as much as 50
