It's Efficacy Fully EstabIished-Rela.
tive Merits Of Two Methods.
While there is no known cure for
blackleg, there is a reasonably GER
tain preventive, as cattlemen are
finding to their satisfaction and profit.
The preventive is accination. There
is no longer any doubt as to it's ef-
fcacy. The principle inolved is as
firmly established as that which un-
derlies the vaccination Of the human
subject for the prevention ct small
pox.
There are two methods of vaccina-
ton in vogue. The older OF these is
we'll understood by stockmen. It
consists of the injection into the ami
NAL (by aid Of a veterinary hypoder-
mic syringe) Of a solution Of blackleg
vaccine powder and water. The nee
die of the syringe is thrust beneath
the skin, being pushed well under,
on the side Of the neck in front of
the shoulder, Immediately in the rear
Of the shoulder, or near the tip Of the
tail.
The later method is by use Of Black
legoids, which are blackleg vaccine
pills. Each pill contains vaccine suf-
ficient for one incubation. Accuracy
eft dosage and s Of administration
are the chief advantages OF vaccina-
ton with B~lacklegoids. An important
saving of time is also effected when a
considerable number of cattle are to
be vaccinated. el
The method of vaccination with
B~lacklegoids is simplicity itself. The
operator inserts a single Blacklegoid
in the needle of the injector selects
the place Of incubation (preferably in.
the side of the animals neck), and,
with a single thrust, plunges the nee
die through the skin, pressing the
plunger well down with the thumb
and holding it down while withdraw
ing the injector. The pill is thus
forced out and lodged in the tissues.
The operation need not consume
one minute. Indeed, in November
last a herd of 113 animals on the Mar
shall FIeld ranch near Stanton, Neb.,
was vaccinated with Blacklegoids in
exactly 35 minutes. This represents
an average of three vaccinations a
minute, and is believed to be record
time for such a performance.
Blacklegoids would seem to repre-
| sent the perfection of blackleg vac
cine, and in their evolution science has
| performed a work of inestimable value
to the cattle-raisers of the country.
The difficulties eff filtering. measuring
and mixing incident to older methods
are dispensed with, and the work of
the operator is limited to keeping
| clean the injector, loading and dis
| charging it. Blacklegoids may be OBJ
tanned through any retail druggist.
Messrs. Parke, Davis & Co., the
wellknown manufacturing chemists
and biologists of Detroit, Mich, have
recently issued an eight-page folder
describing in detail the cause, symp-
toms and nature of blackleg, which
we are informed they will be pleas
ed to send to any stockraiser, post
paid, upon request. In it are explain
led fully both their Blacklegoids,
which they particularly recommend
for the reasons suggested, and their
"Blackleg Vaccine Improved" which
they continue to market and which
for several years has been the black
lex vaccine most IN demand in the
various stockraising regions Of the
country. Every cattleman should
send for a copy of this folder.
