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.

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