profit of $10.71. The interest on the money received 

 from Lot 24 for the 56 days would have amounted to 

 $4.61 at 8 per cent. This leaves $6.10 for the care and 

 labor of keeping, wear and tear on sheds and risk on 30 

 hog-.s for 56 days. 



Lot 26, of Experiment No. 3, which follows, gives a 

 comparison of a still more extended feeding period, run- 

 ning 259 days from July 28, 1906, to April 13, 1907, 

 with a continuous light grain ration until the last 42 

 days. In this lot the daily profit per pig runs slightly 

 below Lot 22 and the total profit per pig slightly below 

 any of the three lots with which it is compared. Had 

 Lot 26 been fed to the final weight of the other three 

 lots, the difference would have been still greater. 



Experiment No. 3 — Three lots of 30 pigs each were 

 run in alfalfa pastures from July 28 to October 20, 1906. 



Lot 25 was fed 2 per cent corn. 



Lot 26 was fed 2 per cent grain, of which 75 per cent 

 was corn and 25 per cent shorts. 



Lot 2y was fed a full ration, of which 75 per cent was 

 corn and 25 per cent shorts, amounting to between 3 and 

 4 per cent. 



The pigs fed corn in Lot 25 gained .1 pound more 

 each per day than those fed a ration 75 per cent corn 

 and 25 per cent shorts in Lot 26. The lot fed corn pro- 

 duced 100 pounds gain with 2T, pounds less grain than 

 the lot fed the same percentage of corn and shorts. The 

 daily profit per pig in Lot 25, fed corn, was 2.8 cents, 

 and in Lot 26, fed corn and shorts, 2.1 cents. The 

 profit per pig in 12 weeks was 56 cents more in Lot 25 

 than in Lot 26. The cost of 100 pounds gain was 37
