figure given. Due to this high fat content rice bran may quickly 

 cake and become rancid. It is high in the B vitamine and con- 

 tains protein of excellent quality. Rice bran could be used in place 

 of wheat bran in mixtures. 



422. Rice polish. — This feed is somewhat lower in protein 

 and fat than the bran, but also is very much lower in fiber. A good 

 product should not contain over 3 per cent. Thus the polish is 

 especially useful for feeding young calves and pigs, and is a fre- 

 quent ingredient of calf meals. It could replace corn meal in vari- 

 ous rations. 



423. Rice hulls. — The hulls are woody and tasteless, and have 

 sharp flinty edges and needle-like points, which are irritating to 

 the lining of the digestive tract. They should never be fed to 

 animals. Reputable millers use them for fuel or packing or throw 

 them away altogether. The best samples of rice bran contain some 

 hulls due to inability to get a complete separation. Some millers 

 may allow considerably more of the hulls than necessary to go 

 into the bran. 



424. Rice feed. — A mixture of hulls and bran is sometimes 

 offered for sale as rice feed. Needless to say, it should not be 

 bought because the hulls are not only useless but also harmful.
