308 AGRICULTURAL CHEMISTRY 



a good quality of oil. When the oil is removed from the 

 flaxseed by naphtha and other chemicals, the product is 

 called ' ' new process linseed meal ' ' which differs from 

 pressure process meal by having the oil more thoroughly 

 extracted and by containing a larger amount of crude 

 protein. 



417. Cottonseed Cake and Meal obtained from cotton- 

 seed after the removal of hulls and the extraction of the 

 oil, are concentrated nitrogenous foods. The meal is 

 lemon-yellow in color and is characteristically rich in 

 crude protein and ether extract. It contains somewhat 

 more crude protein than linseed meal. Cottonseed meal 

 is a concentrated nitrogenous food and can be fed, when 

 properly combined with other foods, to sheep and beef 

 and dairy animals. It cannot safely be fed in large 

 amounts nor for a long period to swine. When used in 

 a dairy ration as the principal food, it influences the char- 

 acter of the butter- fat, producing butter with a high melt- 

 ing-point. 



418. Oat Feed is a product obtained in the manufacture 

 of oatmeal. It is variable in composition and consists of 

 light-weight oats mixed with oat hulls. Oat hulls have 

 about the same composition and feeding value as oat 

 straw and are frequently used for the adulteration of ani- 

 mal foods. In the purchase and use of oat feeds, par- 

 ticular attention should be given to their composition. 

 High-grade oat feed is valuable, but when consisting of 

 any appreciable amount of oat hulls, the food value is 

 proportionally lessened.
