State College Expert Reviews Elk
periments in Milk Feeding in
View of Present Milk Surplus.

J. sotola, Washington State College
Either whole milk or skim milk fed
alone is not we'll adapted for feeding
pigs. The capacity Of pigs for milk
is limited. When their digestive tract
is filed and their appetite satisfied
the amount of milk solids actually con-
sumed is not sufficient to produce sat
isfactory gains.
Experiments where whole milk was
fed as a protein supplement with &C.
real grains are not obtainable, prob
able due to the fact that whole milk
has very seldom been low enough in
price to justify such practice.
The Storrs Station Of Connecticut
in their Bulletin 81 report two expert
ments with very young pigs where
skim milk and whole milk testing 3.54
per cent butterfat were fed to two lots
of pigs in unlimited amounts.
Pigs weighing 16 lbs. at beginning
of the experiment consumed 51S lbs.
of milk in so days and weighed II lbs.
at close of the feeding period. This
shows the daily milk consumption to
be about So lbs, and the average daily
gain to be 81 lbs. The milk required
per 100 lbs. gain was 924 lbs. If con-
densory milk is selling at $40 per 100
lbs. containing similar fat content,
then the cost of 100 lbs. gain is $15.71.
A similar pig fed 10 to l mixture of
barley and tankage would consume
450 lbs. grain mixture per 100 lbs
gain at a cost of $40, if the barley is
valued at $40 per ton and tankage at
$50 per ton.
Milk Unsatisfactory
When skim milk was fed alone TO
pigs very unsatisfactory results were
obtained. Pigs weighing 20 lbs. were
fed for 80 days and made 100 lbs
body gain on 1903 lbs. skim milk. BY
comparing this test with the previous
one / lb. of whole milk has the replac-
ing value of 1853 lbs. skim milk, when
both are the sole source Of feed.
Experiments where skim milk was
fed as a protein supplement are fairly
numerous and exhaustive.
Milk and Grain Better
In similar experiments at the Con-
uecticut Storrs Station pigs fed skim
milk and grain weighed 24.5 lbs. at be.
ginning of the test.
They gained 119 lbs. in Sc days for
an average daily gain OF 1.Ss lbs.
They consumed 233 lbs. grain and S36
lbs. skim milk per 100 lbs. body gain.
A summary of these experiments in
volving 80 pigs weighing S4.5 lbs. at
the start showed the requirement per
100 lbs. body gain to be 253 lbs. grain
and 1886 lbs. skim milk.
Skim milk when fed in proportion
of 1 part grain to y lbs. skim milk
was more economical than when Z to
S'parts skim milk were fed.
Michigan Tests
At the Michigan Station a summary
OF work Of this type shows that 325
pigs fed cereal grains supplemented
by skim milk made 100 lbs. body gain
on 1860 lbs. grain and 1851 lbs. skim
milk.
In this instance 100 lbs. of skim
milk have replaced 20 lbs. grain. Cal
culated on the basis of $3.50 per
ton for the different cereal grains used
which included corn, wheat, rye and
barley, the value of skim milk ranged
from z to IL cents per pound Best
results were obtained when lbs. OF
milk were fed to each pound of grain
Wisconsin experiments conducted
by Henry, where So pigs averaging loo
lbs. were fed, show that the best pro
portion to feed skim milk with corr
is 8 lbs. of skim milk to 1 lb. corn
Under those conditions it took 321 lbs
corn and 5S5 lbs. skim milk to produce
100 lbs body gain, and 100 lbs. skin
milk replaced 81 lbs. grain.
AS the proportion Of skim milk wa'
increased to 10 parts for part grain
it tok 207 lbs. corn and 1876 lbs. skin
milk per 100 lbs. gain and 100 lbs
skim milk replaced only Is lbs. corn
Bulletin 81 of the Utah Station re
ports that 100 lbs. of skim milk re
placed 20 lbs. of grain. When skin
milk was fed alone to 66 lb. pigs, they
required 1877 lbs. of milk per 100 lbs
body gain. The pigs in this expert
ment were heavier than in the Con
necticut test and their requirement
per unit gain is normally expected te
be higher.
Work with LOG pigs weighing about
100 lbs. each reported by various ex
pertinent stations where corn and
skim milk were fed in the proportion
of 1 to 21s, 100 lbs. skim milk replaced
