H/Iiscellaneous By-Products. 



None of the by-products under this heading are in general use. Barley feed, of 

 which two samples were collected, came into prominence during the war. At the 

 present time very little is offered. The lot put out by the Quaker Oats Company 

 more nearly resembled barley meal m composition. Corn feed meal is a by-product 

 from the milling of corn, somewhat resembling hominy feed in composition. Oat feed 

 should be classed as a roughage rather than as a concentrate on account of its high 

 fiber content. Its principal outlet is as an ingredient of stock feeds. Mellin's Food 

 Residue is, as the name indicates, a by-product from the manufacture of Mellin's Food. 

 It has not over 90 per cent of the nutritive value of wheat bran, and its principal value 

 would be to give bulk to a ration. If used as a bran substitute, however, a ration would 

 require a little more of the high protein feeds in order to compensate for its lower 

 protein content. 



Inspection of Prepared Feeds. 



Under this heading is listed a group of feeds consisting of two or more grains or 

 grain by-products mixed either in the attempt to make a more satisfactory ration, or in 

 order to make low-grade material more salable. 



Cottonseed Feed. 



Cottonseed feed is a mixture of cottonseed meal and cottonseed hulls. A mixture 

 of 1,100 pounds of 43 per cent cottonseed meal and 900 pounds of delinted cottonseed 

 hulls would make a mixture having practically the same protein content as the sample 

 analyzed. It is believed that the price asked, $46 a ton, was exorbitant as compared 

 with that of cottonseed meal. 



Wheat and Rye Mixtures. 



Such mixtures of wheat and rye by-products are satisfactory substitutes for wheat 

 bran or wheat mixed feed. The samples analyzed were of good quality. 



Dairy Feeds. 



The dairy feeds are usually sold as complete grain rations for milch cows. The 

 claim made by some manufacturers ■ — that these mixtures are scientifically blended — 

 carries but very little weight, for different brands vary widely in protein content (16 to 

 26 per cent). If the consumer believes it to be economy to purchase ready-mixed 

 rations, preference should be given to those brands which do not contain oat hulls, 

 screenings or other products of low feeding value. With few exceptions, the samples 

 collected mamtained their guarantees. 



Molasses Feeds. 



The molasses feeds are grouped according to their protein content. The group 

 containing 15 per cent or more of protein usually contains oat feed, oat clippmgs, grain 

 screenings or other low-grade by-products which, while they serve as an excellent 

 absorbent for the molasses, do not add materially to the value of the mixture. In 

 general, it is believed that these mixtures should sell at a price below that of wheat 

 bran to receive any recogniticn as an eccnomical part of the dairy ration.
