NUTRITION OF FARM ANIMALS 



Let us suppose the following feeding stuffs are available to 

 a dairyman at the prices named : 



Prices of feeds per ton 



Oats (40 cents per bushel) $25 



Corn meal 25 



Wheat bran 21 



Wheat middlings (flour) 24 



Dried brewers' grains 23 



Gluten meal 27 



Cotton seed meal (prime) 30 



Old-process linseed meal 33 



The supply of coarse feed on the farm is sufficient to furnish 

 each animal per day 32 pounds of silage and 8 pounds of clover 

 hay ; the cows average 1000 pounds each and may be expected 

 to produce per day about 24 pounds of milk testing 4.5 per cent 

 fat. 



The first step is to compute, in precisely the same way as in the 

 previous example, the estimated requirements of these cows 

 per day as follows : 



The amount of silage and clover hay available will furnish, 

 according to Table VII, the following amounts of dry matter, 

 digestible protein, and net energy value :
