HOG FEEDING EXPERIMENT
REPORT TO Be ISSUED SOON

Oregon Agricultural College, Cor.
vaIlis-An even two dozen hog feeding
experiments that have been actually
performed at the College will soon be
publlsh In the hog feeding expert.
meri bulletin TO be issued by the Ore
gon Agricultural College. I'VE are
not attempting" says the author OF
the bulletin, ito give general trea-
tise on feeding and management Of
hogs. nor TO cover all the points Of in
terest TO hog feeders Of Oregon and Of
the Northwest, but rather an exact
record Of the last ten years.
A brief popular summary Of expert
mepts recorded In this bulletin and
also Of experiments performed at vari-
GUS branch experiment stations will be
published In Station Bulletin No. 131. :"
! Most Of the experiments deal with
fattening pigs on common feeding
stuffs Of Oregon. In accord with
the general practice In the Northwest,
mostaof the pigs were put on full feed
at sIiaverage live weight of approxi-
mateiy 100 pounds and kept on the
feed for go days. 1t was expected
that at the end Of this time the pigs
would be In marketable condition and
weigh approximately 200 pounds each.
Most lots Of pigs were composed of
from five to ten each, and even with
this number there were variations of
about 10 per cent In rate and economy
Of gain even though all individuals in
the different lots were on the same
feed and kept under identical condi-
tions For these reasons growers are
advised not TO put too much weight on
differences amounting to less than 10
per cent. In tests comparing two
differ9nt feeds, the fact that one lot
gave 3 per cent better than the other
should not lead the grower to assume
that the difference was due more to
feed than to individual variation Of the
pigs. and IL no other tests supported
the inferences the only safe conclusion
TO draw from the one test il that as
far as this test is concerned it was not
proved that one feed was better than
another.
The feeding test was made with a
view to determine the relative feeding
value Of chopped wheat and chopped
barieg. In this test 100 pounds of gain
was made with chopped wheat, with 22
pounds less wheat than barley, that is,
the amount of chopped wheat to pro-
duce gain of 100 pounds was 478
pounds, while the amount of barley re-
quired to produce 100 pounds gain was
500 pounds. This was 4.6 per cent
less wheat than barley. Barley proved
superior to wheat during the first part
Of the test, but did not do so well dur
ing the latter part.
Lot one was fed chopped wheat and
lot two chopped barley. In the first
fourteen-day period those fed wheat |
Increased in weight from 102 to ia
pounds average, while those fed barley |
increased from 81 to liz pounds. The
of IL pounds produced by
feeding wheat was secured by a daily |
iced of S.96 pounds of chopped wheat
per head, and the gain of 15 pounds
was secured by an average feed of Alt
pounds Of chopped barley. The aver
age daily gain of the wheat fed lot was
So Of a pound, while that of the bar
ey fed lot was LOT pounds.
Lastly, for this period the amount |
If chopped wheat required to secure
100 pounds Of gain was AGO pounds,
md the amount of chopped barley to
secure 100 pounds of gain was 3S9
pounds.
An examination Of each of the five |
periods and also of the entire time
showed that these rations did not hold
good for the entire time, and swine
feeders will be able to draw their own
as to the relative value,
not great, of chopped wheat |
md chopped barley as hog feeds.
