if combined with 12 to 15 pounds of coarse fodder as 

 timothy hay. For average work, however, more food is 

 required, and the amount of grain should be about equal 

 in weight to the coarse fodder. For heaviest work, the 

 grain should exceed the fodder in weight. Pure clover 

 hay, on account of its mechanical condition, is not suita- 

 ble for the feeding of horses. Timothy hay, blue grass 

 and the different varieties of prairie hay are all suitable, 

 if cut and cured when mediumly ripe. Early cut 

 fodders are not as satisfactory for the feeding of horses 

 as for the feeding of other kinds of animals. There 

 is a tendency to confine the ration of horses too largely 

 to one grain, oats, which usually makes an expensive 

 ration. Experiments have shown that a larger variety 

 of foods is desirable. Corn, barley, ground wheat, bran 

 and other milled products are all suitable for forming part 

 of the ration for work horses. For purposes of variety, 

 carrots or potatoes in small amounts may be fed. Oil 

 meal to the extent of about one- fourth pound per day is, 

 also valuable. For average work, the grinding of grains 

 is not necessary ; for hard work, coarse grinding results 

 in a return of a larger amount of the net energy of the 

 foods. 



474. Foods Required for Beef Production. Accord- 

 ing to the table of feeding standards from 25 to 30 

 pounds dry matter containing 2.5 to 3 pounds digestible 

 protein, and about 15 pounds digestible carbohydrates are 

 required for a 1000- pound animal. As pointed out by 

 Jordan, in the "Feeding of Farm Animals," these stand- 

 ards are too high for economic feeding. As the result of
