OF Animal Industry. stationed at Nit
chell, s. D., at the request of the
County Farm Bureau, spent three
days last week and one day the week
previous. holding a series of meetings
on Hog Cholera Control in Hand
County.
The hog cholera situation is prob
ably the worst IL has ever been In this
section Of the state. DIR. Harrington
during his visits spoke at nine differ
ent meetings in as many different
communities. The information he left
will be OF great benefit to the Hand
County hog growers. Many false and
mistaken ideas regarding this disease
and other diseases associated with
Hogs were corrected by DIR. Harring-
ton.
In the past nineteen or twenty years
since the discovery hat hogs could be
immunized against Hog Cholera, many
stories of unknown origin and un-
sound practice, have been advanced
and passed from mouth to mouth by
laymen and veterinarians. regarding
methods and results.
DIR. Harrington speaks from his W
actual field experience In Hog Cholera
control work and what he says is not
theory. He has followed up hundreds
OF treated herds, treated hundreds of
them himself and carefully recorded
the results. His work has carried him
owe Iowa, Nebraska, Kansas, Colora-
do and Oklahoma, and now South Da-
kota.
A summary OF the latest and best
information on Hog Cholera Control,
as given by Mr.. Harrington follows:
ID. IL is known positively that
there Is no definite length of time the
temporary immunity will last that is
produced by the serum alone treat
ment. IL has been known to run in
one weeks time.
t2). Pigs from immune sows are
net immune to Hog Cholera. Small
pigs have a strong natural resistance
ana nave frequently been known to
withstand an injection of l &C of virus
without any serum and still not de-
velop Cholera. This natural resist
ance becomes much lessened by O.
ing time and II the pigs are exposed
they will contract Cholera.
Cd. Sows heavy with pig can be
double treated without any bad re-
suits If the work is properly done.
|Sows In pig must not be thrown for
purpose of treatment, but snubbed
with a rope around the upper Jaw.
"a. All r and virus shipped
interstate is made according to basic
principles laid down by the federal
government, and all such serum and
virus is subjected to the same test.
under federal inspection. They
should therefore all be OF equal value
as a preventative of Hog Cholera.
t5). Most of the abcesses after
vaccination come from unclean syrine
es. The syringe must be taken apart
and the various parts thoroughly
cleansed and then put in a pan Of
water and brought to a boil. com

10. The present Hog Cholera Is
NOT as acute as the Hog Cholera of
~ or 10 years ago. IL is now of a
more chronic type and frequently goes
aiGng some time before definite dag
nosis is made.
VI. Bacterins for so-called Swine

are worthless and are generally given
as an excuse for hog cholera yaccin-

properly immunized against Cholera
can be put into a pen with hogs sick

no contract the disease. In other
words. these conditions follow cholera

cillosis are caused by germs that are
ever present In the hogs body but
are awakened to activity by the condi-
tion OF temperature and weakness
brought on by Hog Cholera. No lab.
oratory has ever yet succeeded IN
producing these diseases BY experi.
mental innoculation. II they wert
separate diseases from Hog Cholera
this could be done.
tS). Not every one can do the work
OF minimizing hogs successfully. This
is a technical piece of work and one
must be thoroughly familiar with Il
before attempting to do ii. There is
a great deal more to treating hogs for
the prevention OF cholera than merely
Milling the syringe and inserting the
needle into the hogs.

given to a hog without any bad re-
suits IL a good normal dose of serum

occur because the virus has not been
properly kept under refrigeration af-
