wheat bran, or as 90 is to 100. It could be used as a component of the 

 grain ration for either cattle or horses, pro\'iding it could be purchased 

 for substantially tliree-fourths of the cost of wheat bran. Two to three 

 pounds daily would be considered a normal amount mixed \\4th other 

 higher gi'ade concentrates. 



7. CXX FEED. 



A by-product known as CXX Feed has been found to some extent on 

 the Massachusetts market. Tliis material bears the name of the Postum 

 Cereal Company, and is supposedly the insoluble residue of Instant 

 Postum, prepared by roasting a mixture of wheat, wheat bran and molasses.

The results of the experiment show the CXX Feed to have a very low 

 digestibiUty, probably due to the roasting that the product undergoes, 

 and to the fact that much of the very digestible soluble carbohydrates 

 has been removed. The protein and fiber appear to be of little nutritive 

 value, and the material as a whole must be pronounced quite inferior for 

 feeding purposes.
