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 occur, especially with the coarse 

 fodder's. Even after allowing for all these factors, 

 results will not follow exactly the quantities of diges- 

 tible matter supplied, because there seems to be a 

 greater adaptability of some feeds to the needs of a 

 particular species. Nevertheless we are forced to con- 

 clude that food materials of the same class must fur- 

 nish energy and building material in proportion to 

 what is digested from them. 



OTHER STANDARDS OF VALUATION 



Certain writers and speakers base the value of ni- 

 trogenous feeding stuffs, from bran up, entirely on the
