It is fully recognized that these figures cannot be 

 taken as absolute relative values. Feeding-stuffs, bear- 

 ing the same name, are not always exactly similar in 

 composition or in equally good condition. Variations 

 in the moisture-content occiu-, especially with the coarse 

 fodders. Even after allowing for all these factors, results 

 will not follow exactly the quantities of digestible matter 

 supplied, because there seems to be a greater adapta- 

 bility of some feeds to the needs of a particular species. 

 Nevertheless we are forced to conclude that food mate- 

 rials of the same class must furnish energy and building- 

 material closely in proportion to what is digested from 

 them. 



386. Valuations based on protein-content. — Certain 

 writers and speakers base the value of nitrogenous feed- 

 ing-stuffs, from bran up, entirely on the protein-content, 

 and they divide the price by the pounds of protein in a 

 ton in order to determine the relative economy of pur- 

 chasing this or that material, and the feeding-stuff in 

 which the protein cost is the least when so reckoned is
