are the most efficient. Tankage Is
made from fresh meat scraps, TAT
trimmings and scrap bones. These
are thoroughly cooked in large steel
tanks under live steam pressure, by
which method the tallow is separated.
The water is then drawn off and the
remaining mass taken out, allowed to
cool and when ground is ready for
shipment.
Tankage contains a large percent
age of high quality protein. 1t is
rich in mineral nutrients, containing
much calcium phosphate, while its
fat contnt is not approached by any
other supplement. Its palatable and
mildly laxative character might well
be compared to that of Gnseed oil
meal. If kept dry it stores well.
Furthermore, its high digestibility is
not impaired with keepink. When buy
ing, it is imperative not to accept
mouldy or damp tankage. 1t requires
about one-fifth more of forty per
cent tankage than it does of sixty per
cent tankage to supplement- the same
amount of grain.
On the average it takes about 555
pounds of corn, 535 pounds of whole
wheat, or 525 pounds of barley per
100 pounds gain on thrifty, we'll
grown shoats. At the Nebraska Ex-
pertinent Station it was found that
421.5 pounds of ground wheat and
2O.74 pounds of tankage were re-
quired for 100 pounds gain, the two
feeds being mixed in the proportion
by weight of 10 parts of ground wheat
and one part of tankage. Pigs can
be fattened and marketed on a short
er feed with ground wheat and tank
age than with whole wheat and tank
age, or wheat alone. Where it is not
practicable to grind the wheat,
small amount of tankage fed with
the whole wheat or barley will ma
terially increase the rate of gain and
the profit obtained. When wheat is
very hard, it pays not only to grind
it but to soak it. Better results are
obtained with ground barley than with
rolled barley, the latter being too
bulky for hogs. Tankage is more
valuable adjunct to the grain ration
for dry lot feeding than when hogs
are being grown and fattened on pas
ture, especially if the pasture be COM
posed of legumes.
It is better to mix the tankage with
the grain at each feed than to mix
it in bulk. For fattening shoats
tankage mixed with barley, wheat or
corn in the proportion Of one part to
nineteen by weight gives the most
economical results. For pigs shortly
after weaving, one part by weight Of
tankage to ten parts by weight Of
wheat, barley or corn will give better
results than a smaller proportion Of
tankage. Tankage has been the most
efficient commercial feed used as q
supplement to wheat, barley and corn
under the prevailing market condi-
tions for the past five years.
Skim milk alone will produce very
unsatisfactory results in feeding pigs,
and more than five or six pounds Of
skim milk per pound of grain is like
ly. to give poor returns. All the milk
products rank high as efficient sup
plements to grain. In containing nine
ty per cent water, it is quite bulky,
which is drawback, but where it
can be obtained it is a most efficient
protein and mineral supplment. With
the exception Of whole milk, skim
milk is our greatest growing food.
The ratio Of grain to skim milk to
be used will depend upon the relative
price of the two feeds and on the age
Of the animals. Immediately after
weaving, larger proportions of milk
will give better results than with old
er animals. Trials at large number
of stations have shown that with ma
ture swine ration of three to one
Of milk and grain will give the most |
economical results in gain of live |
weight. Henry found that when skim
milk and corn meal were fed in the |
ratio Of one to three that 327 pounds |
of milk were required to save 100
pounds of meal; in the ratio of three
to five, 446 pounds; five to seven, STA
pounds, and seven to nine. 552 pounds /
and on the average for all trials AIS |
pounds. The value of separator skim
milk for feeding purposes is variously
estimated at fifteen to twenty-five
cents per hunderd pounds. In general
six pounds of skim milk are of the
same value as one pound Of grain. At
one cent pound for this $50 toni
100 pounds of skim milk would, there
fore, be worth sixteen cents, and at
IL cents for grain $3.50 per toni it
