THE HOG INMSTKY 
173 
experiments had to do with alfalfa hay. In the first, the hogs used 
were of mixed breeding — Berkshire and Poland China representing 
about tin' average of Kansas farm hogs. The alfalfa was of good 
quality. 
Two lots were fed — one receiving the hay whole in greater quantity 
than it would consume, the other having ground hay. In the second 
test the meal-fed Lo1 received some cotton-seed meal — 0.16 pound to 
each pound of Kafir corn, which did not affed the hogs seriously. 
This test was conducted during the most severe weather of the winter, 
the thermometer registering 32° F. below zero February 12, ten days 
after the experiment began. 
In the third test the grain was wet with water at the time of feed- 
ing. The alfalfa hay had been cut late and was rattier woody. 
The Utah Station " fed one lot of hogs on a mixture of equal parts 
by weight of chopped wheat and bran, wet. Another lot had the same 
grain ration with chopped alfalfa hay added. " The alfalfa used was 
well cured and was prepared b} T running through an ensilage cutter, 
the blades of which are arranged for cutting into half -inch lengths." 
The pigs were thrifty grade Berkshires. 
The .Montana Station 6 fed three lots of hogs to compare the feeding 
values of a grain ration with sugar beets and alfalfa hay as roughage 
with a ration of grain only. The results of the lots that were fed on 
grain alone and on grain and alfalfa hay are presented herewith. The 
lot on grain alone received a ration consisting, during the early part of 
the experiment, of 2 parts of damaged Avheat and 1 part oats, barley 
taking the place of the wheat during the latter part of the experiment. 
The hay-fed lot had the same ration with alfalfa hay added. The 
alfalfa hay was run through a cutting box, moistened, and mixed 
with meal. The hogs were by a Berkshire boar out of high-grade 
Poland China sows. They had previously had the run of a stubble 
field, with some clover pasture.
