The pigs were weighed at weekly intervals beginning May 20 

 and continuing to November 11. Table XII gives the date, kind of 

 feed and average daily gain of each pig while on test.

Table XII indicates that with two exceptions each time the 

 pigs were changed from a grain ration to garbage, the average daily 

 gain increased appreciably. On the other hand when changed from 

 garbage to grain, which took place September 16 to September 30, 

 each animal slumped decidedly in daily gain. Two of the animals 

 showed a decided increase in daily gain when changed from a rolled 

 liarley ration to one of garbage during the last period of the 

 experiment. 



Table XIII gives the average daily gain in pounds for each 

 of the three pigs while fed on garbage as compared to grain.

The three gilts which weighed 81, 89, and 92 pounds, respec- 

 tively, on May 20, weighed 328, 346, and 320 pounds, respectively, 

 at the end of 175 days. The gain during this period was 724 pounds. 

 They were fed garbage 105 days, during which time they gained 

 464.2 pounds and they were fed grain 65 days, gaining 259.8 pounds. 

 At this rate the average daily gain for the entire group amounted 

 to 1.455 pounds for the garbage fed hogs and 1.265 pounds for the 

 period they were fed on grains. This indicates that greater gains 

 were produced on garbage than grains as each of the pigs made 

 greater gain while being fed garbage. 



The garbage fed to the three gilts cost approximately $5.00 a 

 month or a total of $17.50 for the 105 days. Considering the fact
