THE COMPOUNDING OF RATIONS 113 



usually may be estimated approximately, especially after 

 one has had some practice. In feeding animals individually, 

 as in the case of horses and dairy cows, the weight of the 

 concentrates usually can be closely approximated by measur- 

 ing the amounts fed. In case of a mixture of two or more 

 concentrates being fed, definite quantities of each may be 

 weighed and mixed in such quantity as to last for some time. 

 Then the weight of a standard measure {e.g. one quart) 

 may be obtained, and the amount given to each animal esti- 

 mated accordingly. It is seldom practicable or necessary 

 to weigh individual rations on the farm. However, it is 

 well to check up the amount being fed by occasionally weigh- 

 ing the ration. 



Estimating Weights of Concentrates. — Table 8 shows 

 the weight of one quart, and the measure of one pound of 

 the different concentrates 



Other rules for the estimation of the amount of grain are 

 as foUow^s : 



1. One vertical inch wagon-box measure is equivalent 

 to a Uttle more than one bushel of ear corn. 



2. One vertical inch wagon-box measure is equivalent 

 to a little more than two bushels of shelled corn, oats, 

 wheat, rye, or barley. 



3. One hundred ears of corn are equivalent approximately 

 to 70 pounds or one bushel. 



4. Two and one-fourth cubic feet in the crib are equivalent 

 to one bushel of well-dried ear corn, or two and one-half 

 cubic feet in the crib are equivalent to one bushel of sappy 

 ear corn. 



5. One and one-fourth cubic feet in the crib are equivalent 

 to one bushel of shelled corn or other grain.
