(1) Low-grade Bij-produds should he sold under their True 



Nauies. 



On aocoinit of our increasing popnlation and prevailing high 

 prices, it is becoming more and more necessary to ntilize all 

 by-products having any substantial food value in the feeding of 

 our domestic animals. AVhile screenings, weed seeds, oat hulls, 

 corn cobs, cottonseed hulls and other low-grade material may 

 contain some nutriment, the foregoing statement should not be 

 taken to indicate that a compounded feed containing one or 

 more of these materials, together with some high-grade con- 

 centrate, is just as valuable as the high-grade concentrate it- 

 self. Where such a mixture is offered at its face value, and 

 no misrepresentation attempted, it is certainly a legitimate 

 article of trade, and should be so recognized. The writer firmly 

 believes, however, that, in order that the consumer may purchase 

 intelligently, the ingredients going to make up a compounded 

 feed should be stated on each package, but no legislation 

 absolutely prohibiting the sale of low-grade material should be 

 enacted unless it can be shown that certain kinds of material are 

 2)oisonons or injurious to the animal. 



The molasses feeds, of which there is an increasing number, 

 form an excellent outlet for certain kinds of low-grade mate- 

 rial, — • especially screenings, — the molasses rendering them 

 more palatable. Most of the manufacturers now grind the grain 

 screenings before using them as a constituent of these feeds. 



There are various feeds now oti'ered wliich contain more or 

 less ground alfalfa. It is believed that feeders cannot afford 

 to pay grain prices for alfalfa hay, even when fine ground ; it 

 is decidedly more economical to purchase the high-grade con- 

 centrates unmixed, and to depend upon home-grown English 

 hay, alfalfa, clover hay and corn silage as sources of roughage. 



(2) Froieln v. Carbohydrates. 

 Many manufacturers claim that the experiment stations 

 place too much emphasis upon the value of protein and too 

 little emphasis upon the value of carbohydrates. This station 

 has never questioned the value and necessity of liberal amounts 

 of carbohydrates in the ration. The question is rather an
