HOG Cn0LERA---WHAT IT Is
NOW TO PREVENT IT

BY Dr.. C. c. LlPP,
State College, Erockings.


Hog cholera belongs to the group Of
animal diseases known as infections
or contagious. 1t is caused by a virus
that escapes from the body of the hog
about the time the first signs Of the
disease become manifest. This virus
escapes through the nose, in the urine
and manure, and the sick hogs con
tinue to spread the disease as long as
1t lives. The carcass Of a hog sick
of cholera is also infectious if placed
in a herd of healthy hogs.
The symptoms most noticeable. al
though not always diagnostic, are as
follows: The hog refuses feed; has
an unquenchable thirst, remains in the
pen most of the time, and if forced TO
10Y he soon returns to his bed.
Weakness and staggering gait develop
in from five to ten days. There is Of
ten a short backing cough, most no
ticeable when the hog is driven from
his bed. Diarrhea is often present, the
bowel discharges being very thin, Of
f%ensive, and of grayish or greenish
color. The discharge from the eyes
is sometimes profuse enough to par
TALLY glue the lids together. Some
times the skin OF ears, abdomen and
thighs becomes red or even purplish.
This is not a constant symptom and is
most noticeable in white hogs.
The above symptoms, together with
the rapid spread of the disease through
entire herds and communities. and the
high rate Of loss are sufficient evil
dence to create strong suspicious Of
the presence of the disease. When
any doubt exists, a competent veteri-
marian should be called to make sew
eral post mortem examinations to set
tie the matter definitely-becausc the
post mortem conditions are practical
ly always ~diagnostic.
There is no known cure. notwith-
standing many statements to the on
trary. Prevention may many times be
effectively practiced by isolating the
hogs so that no person or stray ami
NAL can get into the Yards. When an
attendant enters the yards to feed. he
should be provided with a pair Of rub
Der boots or rubbers that are kept in
n solution OF disinfectant close by
the gate. The generous application Of
q disinfecting solution about houses
and yards is highly recommended. Any
Of the coal tar dips will answer II
used in the strength OF five ounces
per gallon Of water. Many outbreaks
OF cholera can be traced to visitors
coming from infected herds. or by the
owner or attendant visiting infected
herds. For this reason it is best II
owners do not visit infected farms
and keep visitors out of their own hog
yards.
Vaccination with hog cholera serum
Is the only known preventive in addi-
ton TO the precautions mentioned
above. When healthy hogs are vac
cinated By a competent person the
loss is very small and the cost nomi-
nal. Nearly every state in the hog
raising districts OF the United States
has placed large sums OF money at
the disposal OF its experiment station
for the production Of hog cholera So
rum for distribution TO their farmers
at cost OF production.
