HOG CHOLERA.
(ArticIe No. 11.)
BY Dr.. M. n. Reynolds, Mime
sofa University Farm.


Hogs can now be protected against
cholera. They can be so treated that
they may be safely put in with chole-
ra-smitten hogs or dying hogs may be
put in with them.
The University is preparing serum
which can be used on hogs so as TO
make them immune to cholera; and
wants people to know what this pro-
lection is; where farmers may get it;
and what it costs.
Certain restrictions concerning it's
! use have been found necessary, as a
result of unpleasant experiences when
unWise use was made of the serum.
Owners are quite sure to be disap-
pointed in this serum when it is
wrongly used.
Owners Of hogs frequently write us
and ask if they can not do their own
vaccinating. Generally we say, mo"
This is for the same reason that it
would be unwise for parents to at
tempt to use diphtheria antitoxin for
their children. Hog g-cholera vaccintI-
tion must be performed in a certain
way and in certain places and must
be exact in every particular.
Our general rule is that the serum
must be used by a trained and respon-
sible veterinarian. The work of vac
cination must be surgically clean;
otherwise infection is apt to occur,
l and pigs die or do badly, when
the trouble is not cholera, as the
farmer usually supposes. Even the
veterinarian who does this work must
agree to certain conditions. He must
agree in advance to make the injec-
tion in a certain place. He must agree
not to use serum where the disease
has prevailed for some time and the
herd is generally infected. He must
agree to use the serum in full dose
and as directed, or not at ALL He
must agree to keep the serum cool
during storage. He must agree to
report his work to the University, so
that we can follow it up and keep u
record Of 9qr results g He IS asked to
take temperatures, wherever pfactic-
al, of suspected hogs before vaccinar-
ing them, and not to vaccinate any
hogs having a temperature over
certain figure
We have freely published our re-
suits for several years. The Univec-
sity assumes no responsibility in vac
cination except as to sending out
clean, safe and potent serum. 1t does
not guarantee vaccination Of hogs
against cholera or any other disease.
The merits of the vaccination, and
evidence accumulated, must be it's
recommendation for use Information
concerning field results is given free
ly; but the owner must use his own
judgment whether to vaccinate or not.
A letter has just been received from
very intelligent farmer; who writes
that his hogs are sick, and says that,
if we are very sure the serum will
cure, and results will be guaranteed,
he would be very glad to have the
serum used.
The University has put man In
the field for the purpose of doing vac
cine demonstration work over the
state. He will conduct such tests as
interested farmers may reasonably
ask for and will visit, when possible,
points where there are outbreaks,
helping with the vaccination and con-
Quoting public demonstrations
Any local farmers organization es-
pecially interested in hog-cholera vac.
cination, and desiring public demon
stration or any reasonable test of tho
serum, will be accommodated as far
as possible. Write the Veterinary Di-
vision of the University of Minnesota,
University Farm, st. Paul, Mimi, for
information concerning such demon
strations.
A Possibility.
