comparative value of feed stuffs, I find that in ordinary prac- 

 tice we can value the feed by the amount of digestible protein 

 it carries or about the amount of nitrogenous element in it, 

 and this for this reason, the carbo-hydrates, the heat-producing 

 or fat-producing element, we can get in straw, in corn stalks, 

 in fodder corn, in timothy, millet hay, prairie hay, and all 

 these cheap fodders, which contain it in abundance. So the 

 only difficulty we have in making a balanced ration is to get 

 the feed that contains a high per centage of digestible protein. 

 It therefore follows that feed is valuable in accordance with 

 the amount of protein it contains. I have made a table giving 

 the different values of the food upon that basis, which is as 

 follows:
