THE COMPUTATION OF RATIONS 



pounds of dry matter, 2.5 pounds of digestible pro- 

 tein, 13 pounds of digestible carbohydrates, and 0.5 

 pounds of digestible fat. Assuming that corn stover, 

 corn silage and clover hay are the most available, 

 we will use such quantities of each as have been 

 found in practice to be fairly representative of the 

 available supply on average farms and about what 

 an animal will eat up clean without tiring her appe- 

 tite. 



As a starting point, we will use 10 pounds of corn 

 stover, 15 pounds of clover hay and 30 pounds of 

 corn silage. The averages for digestible nutrients 

 in these feeds are the following: 



The second step in the computation is to calculate 

 the pounds of digestible nutrients in the quantities 

 of each of these feeding stuffs. It is clear, for in- 

 stance, that 10 pounds of corn stover will contain 

 just one-tenth as much protein, carbohydrates and 

 fat as TOO pounds. If each of these factors be 

 divided by 100 and multiplied by 10, we shall have 

 the amounts of each constituent that 10 pounds of 

 corn stover will furnish the animal.
