FORMS OF NITROGEN. 



In reporting analyses of fodders and feeding stuffs, the term protein 

 is used to include the total nitrogenous material present, the amount 

 of protein being ordinarily obtained by multiplying the total nitrogen 

 present by the factor 6.25. It is well known that the protein group 

 includes a number of constituents beside the true proteids, prominent 

 among the nonproteid bodies being the amid group. 



In connection with the analyses of Hawaiian feeds, the proteid and 

 amid nitrogen as well as the total nitrogen were determined in man} T 

 of the samples, the methods followed being those recommended by the 

 Association of Official Agricultural Chemists. a The data obtained are 

 summarized in the following table, which shows the total proteid and 

 amid nitrogen and the calculated crude protein, true protein, and the 

 amids as asparagin.
