sisted of three pigs, usually recently weaned. In all 

 cases the food was fed dry. 



Rice polish versus corn meal in connection with skim 

 milk. — In the first experiment, made in the spring of 

 1902, skim milk was fed in connection with either com 

 meal or rice polish. The results were as follows : 



Corn meal and skim milk 89.5 



Rice polish and skim milk 109.0 



2.1 

 1.7 



4.65 

 3.67 



It will be seen that in connection with skim milk, rice 

 polish was more effective, pound for pound, than com 

 meal. 



Rice polish versus corn meal alone, first experiment. 

 At the end of the fifth week the skim milk was dropped 

 from the ration of both lots and the rate and economy 

 of growth were immediately greatly decreased, as shown 

 below. 



It then required to make one pound of growth 6.7 

 pounds of com meal or 6.7 pounds of rice polish. In 

 this test, in which the conditions were unfavorable to 

 rapid gains, the rice polish and corn meal were of equal 

 value. 



Rice polish versus mixed grain. — The following test 

 was made with a different litter of pigs just after wean- 

 ing. The experiment covered, in addition to the pre- 

 liminary^ peiiod, five weeks, terminating June 11, 1902. 

 There were three pigs in each lot. 



The mixed grain consisted of one-half cowpea meal, 

 one fourth corn meal, and one-fourth rice polish. This 

 was fed in comparison with a grain ration of rice polish, 

 the pigs of both lots receiving in addition a nearly equal 

 amount of skim milk.
