HOG CHOLERA

No Known Cure Says the state Col
lege Veterinarian. All deE
Cholera Cures are Fakes.
Every supposed hog cholera
.scure" known to man has been
thoroughly tested aud has been
found wanting, according to the
State College Veterinarian, DR..
C. c. Lipp. He says emphati
cally that there is absolutely no
cure for hog cholera, and that it
ls 9 useless waste OF money for
farmers to buy the ''cures'
advertised or recommended.
Whiskey, coal screenings, car
bolic acid spray, ETC., ETC., have
no curative value whatever. Vet
erinarians all over the world are
agreed that as yet no cure has
been found.
Altho there isno cure for cholera,
there is a preventative, says Or.
Lipp, namely serum vaccination
of healthy hogs by a competent
veterinarian. 'sIt has been
demonstrated time and time
again that when potent serum is
properly used on healthy hogs,
the results will be most salts
factory. All hogs haviog cholera
when vaccinated are almost GER
tain to die ," The death OF a
vaccinated hog may not mean
that the serum is worthless. 1t
might be caused by the fact that
the hog is already sick, that the
dose is too small, or that the
vaccination is improperly done.
Serum must be kept in a cool
place and used as soon as. possi-
BILE after received. Allsyringes,
needles, cups, etc.. must be abso-
lutely clean. DR.. Lipp advises
farmers to employ graduate
veterinarians for vaccinating
rather than to try it themselves.
Immunity against cholera is OF
two kinds, namely temporary
and permanent. Temporary
immunity lasts for several weeks
to several months. Permanent
immunity lasts during the entire
life Of the hog. Temporary i'm
munity is produced when . herd
Of hogs, in which there is no
cholera or exposure to cholera,
is vaccinated with serum only.
In other words the hogs are pro-
tected from cholera from several
weeks to several months. At
the expiration of this immunity
the hogs again become suscep-
tible, and will take cholera it ex-
posed to it.
When permanent immunity
is desire d the hogs must receive
the serum treatment and at the
same time either receive q small
dose of cholera virus or be ex :
posed to cholera by being placed
in yards with sick hogs, or on
farms where there is no cholera,
by introducing several sick hogs
or carcasses Of hogs dead Of
cholera. By this means a nat
ural infection occurs at the same
time the hogs receive the serum
and the result is permanent i'm
munity. For this reason It is
necessary to use virus for the
production Of permanent immun-
ity on farms where cholera ex-
ists providing Ill vaccinated hogs
are exposed to the disease.
When hogs are vaccinated with
serum and virus as mentioned
above the immunity is secured
by what is known as the serum
simultaneous method, It con-
sists in giving simultaneously
both the cause Of cholera and the
serum as preventive.
When serum simultaneous
method is employed. there is al
ways more danger Of loss than
when the serum alone is used.
There is also the added danger
Of spreading cholera because
virulent blood is used. On
account Of the greater danger
from loss and Of spreading chol-
era it is most urwise for anyone
but an experienced veterinarian
to attempt vaccinating by this
method. However, when prop
erly done. results are most
gratifying.
Still another method Of secur-
ing permanent immunity is often
used in very valuable herds
where no cholera or exposure to
cholera exists. This method is
known as the double method and
is more expensive than either.
It consists Of vaccinating first
with serum alone which pro.
duces 3 temporary immunity.
