A feeding-stuff which will serve to make the 

 ration up to the standard is then sought, and it is 

 calculated what quantity is necessary for the 

 purpose. In this way a large number of suitable 

 foods or mixtures are found, as, for example, those 

 given below :

The small differences from the feeding standards, 

 which are seen above, are absolutely unimportant, 

 for in no case can the nutritive value of a food-stuff
