linseed-oil meal or oat-meal. The oat-meal by-product 

 gave very good results, but was not eaten with relish, 

 especially in the first part of the experiment. 



BICE PRODUCTS 



In the manufacture of table rice, three by-products 

 are produced — rice bran, ripe polish, and rice hulls. 

 The last feed contains an average of about 35 per cent 

 fiber and is too bulky and hard to digest to be suitable 

 in any quantity for pig-feeding. Rice bran, also, con- 

 tains from 12 to 16 per cent fiber and is consequently 

 more bulky than wheat bran. Both rice bran and rice 

 polish are rather extensively used in the South. Being 

 carbonaceous like corn, they require about the same pro- 

 portion of protein feeds in order to insure the best results. 



Rice bran and rice polish versus corn. 



Dvorachek and Fowler * of the Arkansas Experiment 

 Station conducted four feeding experiments in each of 

 which rice bran and rice polish were compared with corn 

 chops (ground corn) for fattening pigs in the dry lot. 

 On one of the trials the feeds were each given without 

 supplement. In the other three from 9 to 10 per cent 

 of the rations was tankage. The results of these four 

 experiments are averaged in Table CXLIX. 



The author of the experiments stated that none of the 

 pigs fed the rice products showed evidences of imperfect 

 nutrition. He also stated that rice bran, due to its tend- 

 ency to become rancid in hot weather, could not be fed 

 economically during the summer. It was also criticized 

 for being too bulky to insure a good finish on fattening
