FEEDING FARM ANIMALS 



pounds of milk there will be needed 1.25 (0.05 X 

 25) pounds of digestible protein and 7.5 (0.3 X 2 5) 

 therms of energy value. The total daily food require- 

 ments per animal will therefore be : 



The second step in the computation is to decide 

 on the kind and quantity of the feeding stuffs. 

 Assuming that corn stover, corn silage, and clover 

 hay are available, we will use such quantities as 

 have been found in practice to be satisfactory, 

 although used in varying quantities. As a starting 

 point, we will use 5 pounds of corn stover, 10 pounds 

 of clover hay and 30 pounds of corn silage. Con- 

 sulting the table giving the digestible protein and 

 energy values, we find that in 100 pounds of each 

 of the above feeding stuffs the following will be fur- 

 nished : 



We now calculate the amounts of digestible pro- 

 tein and of energy contained in the quantity of each 

 feed selected and arrange them as below :
