The result of each trial was very iiiucli the same as the average of 

 the three trials. Lot I in each trial gained more rapidly, made cheaper 

 gains, took on more tinish and sold at a higher price per i)Oimd than

 rapidly than Lot II, they were not considered to be worth any more 

 by the buyers. The dressing percentage in each case showed that Lot 

 III was better finished and worth more than Lot 11. 



In the 1922 report attention was called to the fact that pigs, fed 

 the commonly grown farm grains in connection with tankage as a pro- 

 tein supplement, all feeds being fed free choice, did not properly balance 

 their own rations. 



One series of trials using the same feeds as were used previously, 

 but combining them according to accepted standards and feeding the 

 mixed ration in the self-feeder have been completed. Tlie results have 

 been as follows : 



Willi the exception of Lid JIA, all lots receiving tlie mixed ration 

 made larger daily gains and required less feed per 100 pounds 'gain. 

 The results of this one test show marked results in favor of the prepared 

 ration over the free choice system. Definite conclusions should not be 

 drawn until two more tests have been completed. 



Many inquiries have been received relative to the value of powdered 

 skim milk as a feed for pigs. To answer this question, Mr. C. D. 

 Christoulias, a graduate student in 1922, conducted a trial with three 

 Lots of pigs, with the following results :
