B, Analyses of Oat By-Products. 



In view of the constant increase in the cost of hay and all kinds of 

 concentrates, it was believed that a study of the value of oat by-products 

 was worth while. 'A visit was therefore made by Mr. P. H. Smith to one 

 of the mills of the Quaker Oats Company and of the H-0 Company, 

 the process of manufacture observed, and samples secured for analysis, 

 which were declared by the manufacturers and beUeved by us to be repre- 

 sentative. In addition, several lots of oat feed were shipped us at our 

 request for the purpose of conducting digestion and feeding experiments. 

 The analyses of aU of these samples follow : —

 sentative.
