A. CLASSIFICATION OF CONCENTRATED FEEDS. 



The term " concentrated feed," taken in its broadest sense, is 

 meant to include the grains and other seeds of agricultural plants, 

 as well as their manifold by-products left behind in the process of 

 oil extraction and in the preparation of human foods. As here used 

 it is applied more particularly to the various by-products. 



The following classification is made on the basis of the amount of 

 protein contained in the several feed stuffs, those in class I. showing 

 the largest amount, and those in Class IV. the smallest quantity.
