HOG FEEDING EXPERIMENT
REPORT TO BE ISSUED SOON


Oregon Agricultural College, Cor
vallis-An even two dozen hog feeding
experiments that have been actually
performed at the College will soon be
published in the hog feeding expert
ment bulletin to be issued by the Ore
gon Agricultural College. I'VE are
not attempting, says the author Of
the bulletin, Ito give general tres-
tise on feeding and management of
hogs, nor to cover all the points Of i'm
terest to hog feeders Of Oregon and of
the Northwest, but rsther m exact
record Of the last ten year,
A brief popular summary of expert
ments 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,
most Of the pigs were put on full feed
at an average live weight of approx
mately 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 pat too much weight on
differences amounting to less than 10
per cent In tests comparing two
different feeds, the fact that one lot
gave 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 if no other tests supported
the differences the only safe conclusion
to draw from the one test is that n
far as this test is concerned it was not
proved that one feed was better thar
another
The feeding test was made with .
view to determine the relative feeding
value of chopped wheat and chopped
barley. In this test 100 pounds of gair
was made with chopped wheat, with q
pounds less wheat than barley, that is,
the amount of chopped wheat to pro
duce a gain of 100 pounds was ATS
pounds, while the amount of barley re-
quired to produce 100 pounds gain wa
500 pounds. This was 4-6 per cent
less wheat than barley. Barley provel
superior to wheat during the first part
of the test, but did not do 30 well dur
ing the latter part
Lot one was fed chopped wheat ant
lot two chopped barley In the frs
fourteen-day period those fed whes
increased in weight from 102 to IL.
pounds average, while those fed barle.
increased from 81 to liz pounds. Tn
increase Of IL pounds produced b.
feeding wheat was secured by a dali,
feed of 1896 pounds of chopped whea
per head, and the gain Of 15 pound
was secured by an average feed of 4. 1
pounds Of chopped barley. The aver
age daily gain Of the wheat fed lot wa
SO of pound, while that of the bar
! ley fed lot was LOT pounds.
Lastly, for this period the amour
of chopped wheat required to secur
|, 100 pounds of gain was 400 pounds
and the amount of chopped barley t
, secure 100 pounds of gain was 38
pounds.
An examination of each of the fiv
periods and also of the entire tim
showed that these rations did not hol
good for the entire time, and swim
feeders will be able to draw their ow
conclusions as to the relative value
certainly not great, of chopped whea
and chopped barley as hog feeds =
