PROTECTIVE
VACCINATION FOR
HOG CHOLERA
Specialist Gives Timely Hints
for Control of Disease

lost every year in Delaware
through hog cholera. The only
way to control this disease is by
protective vaccination. By CO.
operation of the State Live Stock
Sanitary Board with the U. S.
Bureau of Animal Industry, we
have in the State hog cholera
specialist who has been looking
after the work here for more than
a year. This specialist, DR.. Eur
kow, makes the following state
ment:
"The control of hog cholera in
Delaware is centered around pro-
itective vaccination in infected
neighborhoods with the local
practicing veterinarians as the
chief mediums through whom this
work is done. Successful vaccina-
tion is dependent on proper ad-
ministration and sufficient dosage
of both serum and virus. II there
are visible signs of disease in the
herd to be treated, correct dag
nosis is essential in order to know
that the hogs are free from other
ailments than hog cholera. Bad
results following vaccination are
very often due to the existence of
some disease other than cholera in
the hogs at the time of vaccina-
ton.
"To establish uniform method
of vaccination and to demonstrate
the efficacy of the preventive
serum treatment in infected
neighborhoods, number Of dem
onstrations were held in different
sections of the state. 1t is believed
that these demonstrations resulted
in more general and timely use of
serum as shown 10y the records of
1918. Out Of nearly 5000 hogs
observed in $50 herds, only 81
animals were found too sick to re-
ceive treatment.
Having on several occasions
demonstrated the proper methods
I of vaccination to veterinarians in
the state, they were left to do the
vaccinating whenever needed, with
occasional assistance whenever il
was asked or deemed necessary
The work of the Bureau of Ami
NAL Industry in the control of hog
cholera in cooperation with stat
authorities has been confined tc
making diagnoses of diseases OF
swine, and occasionally, of livt
stock, holding post-mortem ex
aminations, and in other ways as
sisting the state forces, farmer:
and practicing veterinarians IL
keeping down hog chilera.
Three Factors in Cholera COntrO
"Three important factors ente
into successful control of hol
cholera. They are sanitation, pro
per and timely vaccination, ant
quarantine of sick animals. Nei
ther one of the above means viii
alone eradicate the disease. SAM
tation is an important means o
keeping hog cholera down in ;
state. This is particularly tru'
where cholera appears in herd
I. | All sick hogs should then b.
separated from the herd and KEEP
penned up to avoid the scatterin,
of cholera infection over the farm
An even better method in positiv,
cases of cholera infection, is tt
Immediately destroy those animals
which show advanced symptoms
of the disease, as very small per
cent of them ever recover even il
treated with serum. All pens tina
have harbored sick hogs shoult
be thoroughly cleaned and the lit
ter and manure removed ant
spread on a field and ploughet
under. The action of the sun will
soon destroy the infected materia
in the field where sick animal.
have been running at large. TIL,
pens and board fences should b.
sprayed with ten percent solution
of cresol compound and after
wards whitewashed. This methot
conscientiously followed will to ;
great extent do away with recur
rences of hog cholera on farm
hereafter.
