Fort Dodge, Dec. 11.-Dr. P. o. Koto
Of Forest City state Veterinarian and
his corps Of assistants, are working
earnestly for the establishment of the
proposed hog cholera serum manu-
featuring station by an act Of the leg
islature at Its coming session. The
new serum is noM made by private
companies and sold at 81 a dose. 1t
can be sold to the farmers by the state
If a station Is provided at q manu-
featuring cost Of 25 cents Should the
state talpe hold of its distribution, the
disease that annually does an esti-
mated damage of $1,500,O00 to Iowa's
hog raising industry could be eradi-
Gated. The station will cost between
$500 and $4,000.
The serum is the discovery OF ex-
perimenters for the bureau of animal
industry at Washington, d. C. Repre-
sentatiyes from twenty hog raising
states, convened at Ames this sum-
mer, were given conclusive proof that
the serum is effective in its work Inc
bureau at Washington tested ut on
many farms, ard farmers in this coun-
ty have tested it. AL who witnessed
these tests declare the battle against
cholera is won. Anyone can use the
process, which has been patented thru
DR.. D. M. Dorsett, chief of the bureau
OF animal industry
Blood and Serum injection.
Federal experimentersr found that
hogs that recover from an attack of
cholera are immune from subsequent
attacks. They also found that the germ
Of hog cholera thrives only in the hog
itself, defying artificial culture that
propagates many other germs. Ihese
two facts formed the basis OF the work
OF the bureau. In the experiments. II
was found that hogs in which cholera
germs were no: present were not mn
munized by injections OF the serum.
Consequently, BLOOD from diseased an
finals was injected simultaneously with
the germs into unexposed hogs.
Hogs were vtlccinated and placed In
mems. A number Of untreated hogs,
called Controls" were placed with
them. with which to make COMPARE
sons. Then all of the hogs were ex-
posed to the disease by placing dying
animals with them.
Results Of Experiments.
The following are the classes into
which the hogs tested were placed, and
the results in each class:
Glass .A-Hof;s Of an infected dis
trict that had. not been exposed to the
disease prior to the test. Serum and
virus were injected simultaneously.
Every vaccinatng hog survived, while
IS per cent Of those not treated per-
ished
Class B-Hotss known to have been
exposed to cho era, but which did not
show symptoms Of the disease. Four
per cent of the yaccinated animals
died while 80 per cent Of the others
succumbed.
Class Clogs In herds containing
sick and dying. Altho but slight sue
cess was expected, only 13 per cent of
those vaccinated with the serum died,
while as per cent Of the controls" were
killed by the disease.
The assistant state veterinarian, D.
E. Baughman, Of this city, made sew
eral tests In this county.
Thirty hogs In Class A were vacci-
mated simultaneously with serum and
virus and then exposed. All survived.
A herd Of ninety, in which animals
were dying, was treated and but eleven
died. Another herd Of twenty, in which
several died prior to treatment was
treated Five per cent died.
The owner Of the animals fed them
green corn as they were recovering
and thereby caused the death Of sew
eral.
How Serum Is Obtained.
Serum was first obtained from a hog
that recovered from an attack Of chol-
placed in q vat and the blood fiber al
lowed to clot and the serum, or fluid
part Of the blood, allowed to settle to
the bottom Of the vat and it was drawn
off.
Several other animals were vacci-
mated with this serum. Subsequent In
jections of blood from diseased ami
mails were made and from thus hyper
immunized animals, serum of high po-
tency was obtained The process of n.y.
per-immunization, or more powerful
immunization, was carried on until a
very effective serum was obtained
Iowa Hogs Worth $75,29s,680.
Census reports give the number Of
hogs in the state as s,366,52O, valued
Vat s75,29s,6S0. The serum will prove ef-
fective in making this number fit for
market.
AS hyper animals are fit
to be eaten after they haye been bled,
the building of the station near pack
ing house is necessary to keep down
the expense Of making the serum.
Corn Crop Esrings $3.50 An Acre.
