full ration after the change was made in the ration, a 

 larger percentage of the grain fed to those lots was rye. 

 To correct this in so far as possible, the rye was figured 

 at the same price per pound as corn. Figuring in this 

 manner should be favorable to the hogs receiving the 

 most rye, as a ration of 50 per cent ground rye and 50 

 per cent corn should give larger gains per 100 pounds of 

 grain than a ration entirely of corn. 



Wintry storms came much earlier than usual and 

 caught the hogs in summer shelters. It required three 

 weeks to provide permanent winter quarters and to get 

 all lots upon a full ration. In order to present the re- 

 sults clearly, the experiment has been separated here into 

 three periods. Period i includes the time the pigs were 

 on green alfalfa; Period 2, the interim between the green 

 pasture and full feed, with suitable winter quarters; 

 Period 3 is the finishing period when the hogs were on 

 full feed. 



Period i, from June 23 to October 20, 1906. 



Lot 22 was fed i pound corn per 100 pounds weight 

 of pigs. 



Lot 23 was fed 2 pounds corn per 100 pounds weight 

 of pigs. 



Lot 24 was fed a full ration of corn, about 3.5 per 

 cent. 



The ration was shelled corn fed dry. All lots on al- 

 falfa pasture. 



During the 17 weeks of the experiment, the average 

 daily gain of each pig in Lot 22 was .5 pound ; in Lot 23. 

 .65 pound; and in Lot 24. i.oS pounds. The amount of 

 grain required to produce 100 pounds gain was, by Lot
