associated with the feed, and for this reason was taken out of the 

 experiment. The nine pigs weighed a total of 1770 pounds and 

 brought $265.50. The gain over cost of pigs and garbage amounted 

 to $73.10. 



Beginning January 20, 1920, and ending May 4, 1920, a second 

 test was conducted. Eighteen pigs weighing a total of 1615 pounds, 

 or an average of 89.7 pounds, were selected. Six of the pigs died 

 from cholera the first week, the remaining 12 pigs were sold May 4, 

 and weighed a total of 2295 pounds. The pigs were on test 105 

 days and the cost of feed was estimated at $20 per month or $70 

 Table V gives the results of the two tests.

According to Table V, gains were made at a cost of $3.72 per 

 hundred in the first test and $5.83 in the second. These are ex- 

 tremely cheap gains in spite of the fact that one-third of the pigs 

 in the second lot died. The pigs did well throughout the test and 

 gave every indication of thrift and satisfactory gains from the 

 feed given them. The supply of garbage at times was not suffi- 

 cient to make rapid gains. It is believed that it is good policy to 

 plan on giving hogs a small quantity of grain along with the 

 garbage, except where garbage is produced in large amounts and 

 can be secured at little cost. 



TWO METHODS OE MAINTAINING SOWS 



The five registred Duroc-Jersey gilts that were raised accord- 

 ing to two different methods have been under inspection for an- 

 other year. These gilts have been exchanged, with the exception 

 of No. 2 which still remains at the University Farm. Thus giUs 

 1 and 3 are now on the Schumaker farm, and 4 and 5 retained at
