extracted by the use of naphtha. New process Unseed meal is 

 somewhat lower in fat and higher in protein than old process. 

 These- goods, so far as sampled, are as guaranteed. 



VISCID OIL MEAL. 



Analyses page 84. 



A sample of viscid oil meal sent by the manufacturers was 

 found to analyze as follows: Water, 7.98 per cent; ash, 6.58 

 per cent ; protein, 30 . 88 per cent ; crude fiber, 11 . 86 per cent ; 

 nitrogen free extract, 37.67; fat, 5.03. 



A sample taken in the open market the present year was found 

 to carry 28.81 per cent protein and 11 .63 per cent fat. So far 

 as the composition is concerned, the goods seem to be of good 

 feeding value. Of course a feeding test would be necessary to 

 ascertain its true feeding value. Unless it can be bought at a 

 much lower price than good linseed oil meal, it would seem to 

 be wiser to use the linseed oil meal rather than the viscid oil 

 meal. 



GLUTLN MEALS AND FEEDS. 



Analyses pages 84 and 8j. 



Gluten meals and feeds are the by-products left in the manu- 

 facture of starch and glucose from Indian corn. Corn consists 

 largely of starch. The waste product in the manufacture of 

 starch and sugar is relatively richer in oil and protein than is 

 corn. Most factories remove part of the corn oil from the waste 

 so that nearly all the gluten meals carry less oil than they did a 

 few years ago. 



Gluten feeds differ from gluten meals in that they contain 

 considerably more of the corn bran and hence relatively less 

 protein, fat and digestible carbohydrates, and more of the indi- 

 gestible woody fiber. Gluten products which were formerly 

 quite extensively used in Maine, continue to be rather unsatis- 

 factory forms of concentrated feeds, chiefly because of their 

 uneven composition. 



Chicago gluten meal made by the Glucose Sugar Refining 

 Company carries about 5 per cent less protein than its guarantee. 

 The analyses of the Maine samples agree in the low protein con- 

 tent with those found in New York, Connecticut, Massachusetts 

 and Vermont.
