CONTROLLING HOG CHOLERA

Many thousands of dollars are lost
every year in Delaware through hog
1 cholera. The only way to control this
| disease is by protective vaccination.
| By cooperation of the State Live Stock
Sanitary Board with the U. S. Bureau
of Animal Husbandry, we have in
the State hog cholera specialist who
has been looking after the work here
for more than year. This specialist,
DR.. ZurkOw, makes the following state
ment:
"The control of hog cholera in Del
aware is centered around protective
vaccination in infected neighborhoods
with the local practicing veterinarians
as the chief mediums through whom
this work is done. Successful vaccin-
alton is dependent on proper admin
istration and sufficient dosage of both
serum and virus. If there are visible
signs of disease in the yard to be
treated,~a correct diagnosis is essen
tial in order to know that the hogs
are free from other ailments than hog
cholera. Bad results following vaccin-
alton are very often due to the exist
ence of some disease other than chol-
era in the hogs at the time of vaccin-
alton.
ITO establish a uniform method of
vaccination and to demonstrate the
efficacy of the preventive serum treat
ment in infected neighborhOods,
of demonstrations were held in
different sections Of the State. It is
believed that these demonstrations
resulted in more general and timely
use of serum as shown by the records
of 1918. Out of nearly 5000 hogs OBJ |
served in $50 herds, only 81 animals
were found too sick to receive treat /
ment.
Having on several occasions dem
onstrated the proper methods of vac /
cination to veterinarians in the State, /
they were left to do the vaccinating
whenever needed, with occasional as I
whenever it was asked or /
deemed necessary. The work of the 4
Bureau of Animal Husbandry in the
control of hog cholera in cooperation .
with State authorities has been con
fined to making diagnoses of diseases
Of swine, and occasionally of live /
stock, holding post-mortem examina-
tiOns, and in other ways assisting the
State forces, farmers and practicing
in keeping down hog
cholera.
Three important factors enter into
successful control of hog cholera.
They are sanitation, proper and timely
and quarantine of sick
Neithe rome of the above
means will alone eradicate the disease.
Sanitation is an important means of
keeping hog cholera down in a State.
This is particularly true where chol-
era appears in a herd All sick hogs
should then be separated from the
herd and kept penned up to avoid the
scattering of cholera infection over
The farm. An even better method in
positive cases of cholera infection is
o immediatel ydestrOy those animals
which show advanced symptoms of the
disease, as a very small per cent of
hem will ever recover even if treated
With serum. All pens that have har-
,Ored sick hogs should be thoroughly
cleaned and the litter and manure re-
moved and spread on field and plow-
d under. The action of the sun will
Don destroy the infected material in
he field where sick animals have been
unning at large. The pens and board
ences should be sprayed with ten per
Ohb SOlutiOn VI Cl65Ol COupOuuu ana
fterwards whitewashed. This meth
d conscientiously followed will to a
reat extent do away with reoccur-
ences of hog cholera on farms here
fter.
Proper disposal of hogs that have
led from any cause whatever is a very
nportant part of sanitation. The
ractice of leaving hog carcasses un-
cannot be too strongly con-
emned. 1t shows on the part of
omeone lack of appreciation of the
eriousness of the offence and is a
reat injustice to the neighborhood.
considerable percentage of cholera
are traceable indirectly to
lrelessness in not properly disposing
the carcasses of animals that die
4 the farm. The large number of
lizards in this State are factor in
lrrying infection, which should be
minated if we are to successfully
'mbat hog cholera and other live
ock diseases"
