The process of manufacture briefly, are
as follows Hogs are immunized by the
injection into their flesh OF blood from
case OF cholera and dose OF reum- In
ten DAYS a large dose OF virulent blood Is
injected into the vein OF the ear, IL the
hog remains healthy after this treatment
he is considered hyperdrimune and
ready TO produce the protective serum.
The serum is made from the blood OF my
perimmuned hogs BY placing the hog IN
a crate and drawing blood from the tail
under antiseptie precautions The blood
l. then defbrinated and a preservative
added. HOGS may be bled at intervals
OF one week and the serum made from
each hog is kept separate and must be
tested for potency being sent out for use.
The tests conducted by the United States
bureau OF animal industry indicate that

not been exposed 10 contaglon practically
all treated hogs remained well. while
more than s per cent Of the untreated
hogs died In herds in which cholera
was present IS per cent OF inoculated
hogs died OF the untreated herds IS per
cent died"
While the serum may in some cases
cure cholera its principal field OF useful
ness is as a preventative. The details Of
manufacture are such that special train
ing in animal diseases and serum therapy
are necessary in anyone who would IN

that this serum Is needed by the farmer
and that the farmer is not prepared 10
