RESULTS OF INSPECTION. 



Cottonseed and Linseed Meals. 



The cottonseed meal as found was guaranteed to contain, 36, 38j, 41 and 43 per 

 cent protein. Cottonseed is usually sold, at least up to the time it reaches the retail 

 trade, on the basis of its protein content. One large jobber has made during the past 

 season a difference of about $1.25 a ton in the price of the meal of different grades. It 

 would be interesting to know whether this difference is in all cases carried through to 

 the consumer. On account of the wide fluctuations in grain prices during the past 

 season it is difficult to demonstrate this point from the data available. 



The general quality of the cottonseed meal sold has improved noticeably over that 

 offered for several years, although the guarantees of certain brands have not been met. 

 The average protein content of seven samples of Buckeye cottonseed meal was ttt of 1 

 per cent lower than the guarantee. 



Linseed meal tested slightly below its protein guarantee as compared with that 

 sold in previous years, and the manufacturers lowered their guarantee to meet this 

 changed condition. This condition was probably brought about by the quality of the 

 seed crushed. Present indications are that this season's meal will be of normal quality. 



The Gluten Products. 



Gluten meal consists very largely of corn gluten, the residue left after the removal 

 of a greater part of the starch, corn bran and corn germ from the corn kernel. The 

 manufacturers have evidently modified their process of manufacturing this product 

 so as to incorporate rather more fat than formerly. Up to 1920 the average fat con- 

 tent of gluten meal was about 1 per cent. For the last two years it has been between 

 3 and 4 per cent. 



The gluten feeds were of average quality. Occasional samples were found to be 

 off color, due to heating, or to be rather coarse, due to poor grinding. While such 

 samples excite the suspicions of the purchaser, a chemical analysis does not usually 

 show that they differ materially from meals more satisfactory in appearance, although 

 a dark-colored, off-flavored gluten feed will probably prove less palatable than a feed 

 of normal appearance. 



The "Continental" and "Farmer Jones" so-called gluten feeds are made by a 

 somewhat different process from the one employed in making the other brands. While 

 excellent feeding stuffs, it is believed that custom at least identifies the name gluten 

 feed with the by-product of cornstarch factories, and the feeds derived from modified 

 methods of manufacture should be called by another name. 



The sample of "Farmer Jones" gluten feed had an exceptionally high protein 

 content. 



Distillers' and Brewers' By-Products. 



Two samples of distillers' grains and three of brewers' grains were collected. The 

 brewers' grains were of good quality. The somewhat limited supply of these products, 

 derived from the manufacture of medicinal liquors, industrial alcohol and non-alcoholic 

 beers, are largely absorbed by the manufacturers of compounded feeds.
