COMPOSITION OF RICE 



377 



xADuisiana Station recommends a standard for rice bran of not 

 more than ten per cent of hulls to prevent its adulteration with 

 rice hulls. Assuming pure rice bran to contain ten per cent of 

 crude fiber and pure hulls to contain forty per cent, the percent- 

 age of adulteration of bran with hulls may be calculated by 

 subtracting ten from the per cent of crude fiber found upon 

 analysis and multiplying by three and one-third.* The New 

 Jersey Station calls attention to the characteristic cells of the 

 hull arranged in several convoluted ribbon-like rows as an easy 

 means of identif}dng ground hulls when mixed with other feed.^ 

 The following table gives recent analyses by the Louisiana 

 Station : 



Rice bran, which is the chief by-product, is characterized by its 

 high percentage of fat, which through fermentation frequently 

 breaks up into fatty acids and glycerine, thus causing a rancid 

 taste which makes the bran unpalatable to domestic animals. 

 When fresh, however, the bran makes an acceptable food for all 

 classes of domestic animals and it is especially useful for mixing 

 with thf more nitrogenous cottonseed meal. Polish has been 

 successfully fed to cattle and pigs, but is more largely used foi
