ALFALFA FUR SWINE I 99 



ill Lot 3, $2.08. The cost of the grain eaten in produc- 

 ing 100 pounds gain with the lot fed 2)^2 per cent was 

 1.30 pounds more than with the lot fed Yz per cent and 

 09 cents more than with the lot fed lYi per cent. The 

 price received per bushel of corn eaten by Lot i was 

 ^2.84; by Lot 2, $1.38; and by Lot 3, $0.92. All these 

 llgures indicate that the lighter the grain ration, the 

 cheaper the gain. But when we consider the profits we 

 iind that the daily profit per pig was, in Lot i, 1.3 cents; 

 in Lot 2, 1.5 cents; and in Lot 3, 1.7 cents. The profit 

 during the 14 weeks on each pig was, in Lot i, $1.28; in 

 Lot 2, $1.48; and in Lot 3, $1.64. The pigs receiving 

 Yz per cent did not do well enough to warrant a repeti- 

 tion of the same test. They had a decidedly stunted ap- 

 pearance. Lot 2 was not as thrifty as most farmers 

 ^vouId demand in profitable feeders, but in later experi- 

 ments 2 per cent grain on pasture has given thrifty 

 growing pigs. 



Experiment No. 2. — In the summer of 1906, three 

 lots of 30 pigs each were selected to test the relative 

 profit in growing and fattening pigs on alfalfa, with a 

 light, a medium and a full grain ration. The plan was 

 to run these pigs on a different percentage of grain until 

 green alfalfa was no longer available in the fall, and 

 then to put all lots on - full ration, marketing each lot 

 \\hen it had reached near the average weight of 225 

 pounds per hog. After the hogs were removed rom 

 the alfalfa pastures, the ration was changed from corn 

 to 50 per cent shelled corn and so per cent ground rye. 

 As there was required a larger amount of grain to finish 

 Lots 22 and 22^ on the lighter rations than Lot 24 on the
