REVIEW OF THE ANALYTICAL WORK. 



Cottonseed Meal. — Many of the samples of cottonseed meal collected 

 ran below their minimum guarantee of 36 per cent protein, the average of 

 the 55 samples reported being 36.6 per cent. Where samples ran sufficiently 

 low they were referred to the Federal Bureau of Chemistry for action under 

 the Food and Drugs Act. One car was seized on account of wide divergence 

 between guarantee and actual content. 



Despite the fact that the quality of cottonseed meal found on the Massa- 

 chusetts markets is gradually decreasing, its use as a source of protein will 

 probably continue for lack of a satisfactory substitute. Where the demand is 

 large enough, meal of higher grade can be secured by paying a premium over 

 the market price for 36 per cent protein meal. 



Cottonseed Feed is a mixture of cottonseed meal and cottonseed 

 hulls. The cottonseed feed usually found contains about 20 per cent protein 

 and from 20 to 25 per cent fiber. Compared with cottonseed meal it is a 

 very inferior product. Unscrupulous dealers may readily sell cottonseed 

 feed in place of cottonseed meal to customers who do not take the trouble 

 to read the guarantee tag. 



Linseed Meal. — The samples of linseed meal collected were all of 

 good quality. Compared with the grade of cottonseed meal which is being 

 sold in Massachusetts markets at the present time, linseed meal is to be 

 preferred when sold at anywhere near the same figure. 



Miscellaneous Oil Cake Meals. Com Germ Meal. — Two brands are 

 reported which were by-products from hominy mills and consisted largely of 

 the ground corn germ after the oil had been partially extracted. They are 

 satisfactory feeding stuffs but are not generally sold as such, the usual prac- 

 tice being to mix the corn germ meal with other corn residues to form hominy 

 feed, of which the corn germ is a legitimate component. 



Cocoanut oil meal approaches gluten feed in feeding value. Trouble is 

 sometimes experienced with it owing to a tendency to turn rancid when 

 not kept under satisfactory conditions. 



Peanut Oil Cake Feeds. — The Liberty Brand consisted of the residue 

 resulting from crushing and extracting the oil from the entire nut, including 

 shell. The presence of the shell gives this product a high fiber content which 

 renders it less desirable as a feeding stuff. 



The Beta Brand is believed to contain a large amount of the peanut skin 

 which surrounds the nut. On account of its lower fiber content it is to be 

 preferred to the preceding brand.
