PROTECTION FROM HOG CHOLERA

The other party, who injects the serum
and the virus, should not handle the
hog.
Wash the mouth of both serum and
virus bottles with Lysol solution before
opening. Pour the serum into the fruit
jar and the virus into the Jelly glass.
Keep both of these glasses covered ex
cept when filling syringes. Dampen a
clean cloth with the Lysol solution and
lay it on a table or box. After filling
both syringes and slipping the needles
on them, lay the syringes on one end
of the cloth and turn the other end
over them for protection.
Inject the serum into the inner and
aeshy part of the ham, as deep as the
needle will go. The virus j injected
into the other ham. The needles, after
each injection, are to be laid in the
saucer of Lysol solution.
The dose for each hog is to be gov
erned by its estimated weight. 1t is
always best to inject an excess of serum
than not enough Remember that you
can easily give too little serum to be
effective, but you can do no harm by
giving an overdose
The Immune Hogs.
1T is first necessary in the manutac-
ture of serum to secure the immune
hogs that are to furnish the blood
which when preserved is the serum.
The main point in making serum is to
produce blood that contains great guam
titles of cholera resisting bodies and
this can only be done with immune hogs
that are capable of receiving large doses
Of virulent cholera blood without any
harmful effect.
These immune hogs are purchased
from farmers who have had them vac
,inated by the double treatment several
months before they were shipped to
market. 1t has been found that hogs
noculated with not less than one C. c.
If virus, when they were .vaccinated by
he simultaneous method, produce the
,est serum and fewer of them die, when
lypered, with the virulent cholera blood.
The death loss which follows the
lypering of the immune hogs is usually
bout 10 per cent. This adds more to
he cost of making serum than any
,ther item. 1t sometimes happens that
he immune hogs were injected with
,nly one-quarter c. c. of virus at the
ime they received the simultaneous
reatment. While this is enough virus

is not a sufficient quantity to give

tand the quart or more of virulent
