Rice polish versus corn meal in mixed grain ration. 



A litter of six Poland China pigs, dropped April 29, 

 1902, were divided into two lots and fed for five weeks 

 on two lots of grain that were exactly similar except 

 that rice polish in one was substituted for an equal per- 

 centage of corn meal in the other. The results of the 



last four weeks of the period follow :

( 40% rice polish 



Lot E } 40% cowpea meal 65.5 3.1 



\ 20% wheat bran 



Both of the above mixtures afforded satisfactory rates 

 of growth, but the one containing rice polish was de- 

 cidedly more effective than the mixture into which corn 

 meal entered. 



Rice polish versus corn fneal alone^ third experiment. 



This experiment was made with two lots of three 

 shoats each and extended over eight weeks, terminating 

 October 1, 1902. The shoats used were the same as those 

 employed in the last mentioned experiment.

The rate of growth was almost twice as rapid with the 

 pigs fed on polish as for those consuming com meal. 



To make one pound of increase in liv6 weight required 

 in this experiment 39 per cent, less of polish than of 

 com meal. 



Average results with rice polish. 



In most of the direct comparisons of rice polish with 

 corn meal the polish proved decidedly superior. 



Taking the average of all five of these direct compari- 

 sons we find that to produce, one pound of increase in 

 live weight of pigs required only 3.73 pounds o^fc^^e 

 polish and 4.74 pounds of com meal. At thi^ateT8.6
