By wheat offal is meant the various by-products 

 Wheat offal, from the flour mills — bran, middlings and mixed 

 feed. Wheat bran and middlings show no adulter- 

 ation ; the variations observed especially in case of the middlings 

 are probably due to the milling process and to the quality of the 

 wheat. The iine light colored middlings containing 19 per cent or 

 over of protein, are worth several dollars more per ton than wheat 

 bran. Colonial middlings, so called, contained an admixture of 

 hominy chop ; the manufacturers do not claim them to be pure wheat 

 middlings. Their cost per ton should be less by several dollars than 

 the genuine article. 



Mixed yi'(?;/ consists of the entire wheat offal, or varying mixtures 

 of wheat bran, middlings and red dog flour. This feed is widely 

 distributed, has a large sale, and most of it is entirely free from any 

 foreign admixture. Unscrupulous parties are beginning, however, to 

 adulterate with material similar to fine ground corn cobs, and a 

 number of samples have been found only testing between 11 and 14 

 per cent of protein, and containing nearly twice as much fiber as the 

 genuine article. In some cases they were simply marked mixed 

 feed, while in two instances they had special brands, namely, Ken- 

 tucky and Purity. The adulteration of this class of feeds is a serious 

 matter, and deserves the earnest consideration of all honorable man- 

 ufacturers and jobbers. The best w'ay out of the difficulty is to 

 brand or tag the product with the name of the manufacturer or 

 jobber, together with a minimum guaranty of 16 per cent protein 

 and 4.5 per cent fat. The simple mark of " mixed feed " is not a 

 sufficient protection or guaranty either to the manufacturer or far- 

 mer, and reform in this particular is urgently advised. 



II. Starchy Feeds. 



This material, as is well known, consists of the 

 Oat feed. refuse from mills engaged in preparation of oat 



meal for human consumption. A considerable por- 

 tion of it is very inferior, and the particular attention of the reader 

 is called to the analyses on page 17. A digestion experiment 

 recently carried out with an inferior oat feed containing about 5 per 

 cent of protein and 25 per cent of fiber,* showed it to contain only 



*The larger the amount of fiber feeds contain, the less the nutritive value.
