Tlie pigs in Lot 22, grown on a light grain ration of 

 I i^er cent of their weight until they averaged 100 

 pounds, and then finished on a full ration, gained for the 

 entire period .83 pound each per day. They recjuired 377 

 pounds of grain for 100 pounds gain, and gave a daily 

 l)roht of 2.6 cents per head. Those in Lot 2^. grown 

 on a medium grain ration of 2 per cent of their weight 

 until reaching the average weight ot 120 pounds, and 

 then finished on a full ration, gained .87 pound each per 

 day. They required 391 pounds of grain per 100 pounds 

 gain, returning a daily profit of 2.7 cents per pig. The 

 pigs in Lot 24, grown and finished on a full grain ration, 

 gained 1.13 pounds each daily. They ate 395 pounds 

 of grain for each 100 pounds gain, and gave a daily 

 ])rofit of 3.4 cents per pig. 



The 30 light-grain ration pigs gave a profit of $179.40 

 in 230 days, or a profit of $0.78 per day. 



The 30 medium-grain ration pigs gave a profit of 

 .fi 1 79.01 in 221 days, or a profit of $0.81 per day. 



The 30 full-grain ration pigs gave a profit of $168.30 

 in 165 days, or a profit of $1.02 per day. 



Lot 22 was kept 65 days longer than Lot 24, and gave 

 a profit of $11.10 more; or, stated in another way, by 

 feeding a light grain ration instead of a heavy grain 

 ration, there was received for keeping 30 hogs 65 days, 

 $11.10. The interest on the money received for Lot 24 

 at 8 per cent for 65 days would be $5.33. This would 

 leave $5.77 for the care and labor of feeding and bed- 

 ding, wear and tear on buildings and sheds, and the 

 risk on 30 hogs for 65 days. Comparing Lots 23 and 

 24, we find that Lot 23 was kept 56 days longer for a
