Two lots of 32 lir»-lb. pigs each were grazed for 70 days on alfalfa pasture, lot 

 1 being fed 3.34 lbs. of ground corn dailj- per 100 lbs. live weight, and lot 2, 

 3.3 lbs. of a mixture of corn and shorts 2: 1, during which time they made an 

 average daily gain of 1.09 and 1.04 lbs. per pig, consuming 4.62 and 4.81 lbs. of 

 feed per pound of gain, costing 3.S8 and 4.62 cts. per pound of gain, and realizing 

 ji profit of $1.54 and 94 cts. per jiig for the respective lots. During the next 49 

 days the pigs were kept in dry lots and fed the grain rations with alfalfa hay 

 in racks, and made an average daily gain of 0.86 and 0.92 lb. per pig, consum- 

 ing 6.10 and 6.21 lbs. of feed per pound of gain, costing 5.13 and 5.89 cts. per 

 pound of gain, and realizing a profit of 32 and 0.4 cts. per pig for the respective 

 lots. 



Two lots of 10 50-lb. pigs each were fed 51 days as follows : Lot 1 corn and 

 shorts 3 : 1 and cut alfalfa, and lot 2 corn and shorts 3 : 1, cut alfalfa and al- 

 falfa tea. The alfalfa tea was used in making a slop feed. These lots made rela- 

 tive gains of 94 and 100, res]iectively. Two other lots of 13 60-lb. pigs each were 

 similarily fed, lot 2 receiving alfalfa tea grounds instead of the tea. the relative 

 gains being 84 and 100, respectively. The tea from 100 lbs. of stewed alfalfa 

 thus saved 47 lbs. of corn, and the tea grounds from 100 lbs. of stewed alfalfa 

 saved 67 lbs. of corn. 



In a second exiieriment in which a lot of 14 50-lb. pigs was fed 84 days 

 ground corn and chopped alfalfa hay 9 : 1, and a second lot received the same 

 ration mixed and moistened with alfalfa tea, together with the tea grounds, a 

 slight advantage in favor of the alfalfa tea was obtained, but not enough to 

 warrant the farmer in going to much, if any, expense to stew alfalfa for hogs.

Alfalfa pasturing experiment, R. W. Axlen {U. S. Dept. Agr., Bur. Plant

 pastured 135 days from March 28 to August 11, 1913, on two plats of i acre 

 each of 4-year-old alfalfa and fed 1^ lbs. of rolled barley per 100 lbs. live 

 weight per day, gained an average of 106 lbs. per pig. Four S9-lb. pigs, pastured 

 55 days from August 11 to October 6 on the same plats of alfalfa and fed 1^ 

 lbs. of rolled barley per 100 lbs. live weight per day, gained an average of 32 

 lbs. per pig. The J acre of alfalfa supplemented by 1,883 lbs of grain produced
