CHAPTER XXII. 
PASTURE AND SOILING CROPS. 
Alfalfa—Bulletin 155 of the Kansas Experiment Station 
gives a summary of results from feeding alfalfa to hogs at 
that institution. The following is quoted directly from the 
bulletin: 
“At this station some years ago, a gain of 800 pounds of 
pork was made from a ton of alfalfa hay, and a little less than 
that amount of gain was made from an acre of alfalfa pasture. 
In another test here, an acre of alfalfa produced $20.20 worth 
of pork, while an acre of rape fed to a similar lot of hogs 
returned $10.05 worth of pork. 
“In a later experiment we found that 100 pounds of 
alfalfa hay saved 96 pounds of corn. Figuring on the basis 
of 5 pounds of corn producing one pound of pork, the 96 
pounds of alfalfa would produce 19 pounds of pork. Estimat- 
ing the average yield of alfalfa to be four tons per acre, on this 
basis it would mean a production of 1600 pounds of pork per 
acre with alfalfa fed in the form of hay in connection with 
corn. This experiment was conducted during the winter 
season. 
“Tn an experiment during the summer, we found that 
170 pounds of green alfalfa, cut and fed to hogs fresh in a 
dry yard, was equal to 100 pounds of corn, and in this experi- 
ment it took 6 pounds of corn to produce a pound of pork. 
Therefore, assuming 170 pounds of green alfalfa would 
produce 1624 pounds of pork, a fraction over 10 pounds of 
green alfalfa would produce one pound of pork. Estimating 
that an acre of alfalfa will vield during the season 20,000
