Jog cholera if the bacons and hams
have not been cured for q sufficient
period of. time. All garbage, table
refuse and kitchen swill, if it must
be FED to swine, should be cooked. We
realize that a mixture such as is OBJ
tanned in city restaurants does not
cook down into an admirable feed,
but nevertheless we will never stamp 4
out hog cholera as long as we feed
garbage and table refuse which con- +
tains infected pork scraps without
first sterilizing it.
The third method is the abuse of
the simultaneous method of vaccina-
ton. In this method the virus Of hog
cholera is used along with hog chol-
sra serum. The virus is controlled In
the body of the v~accinated hog by the
use of the proper amount of serum;
nevertheless, to get the proper i'm
munity the animal must suffer in a
very mild degree from hog cholera. It
-~aturaTiy follows that if this virus is
not properly controlled you viii cause
an outbreak of hog choera rather
than an immunizaticn of the animals
vaccinated.
| have no hesitancy in saying that
the abuse Of the double or %multan-
GUS method of hog cholera vaccina-
ticn has lost to the hog growers of
the United States many millions of
dollars. / am advised by sanitary Of
ficials in some Of the greatest hog
producing states in the United States
that the abuse and indiscriminate use
of hog cholera virus has caused some
Of the worst outbreaks of hog cholera
with which they have had to deal. I
may state also that Canada will not
permit the use of hog cholera virus
and for a number of years they even
prohibited the importation Of swine
into Canada that had been immun-
lied by means of the double vaccina-
ton.
There is considerable agitation 60
ing on at the present time through
out man states in the United States
as to why a hog grower himself can
not ship in virus and administer it
= along with serum to his hogs. No
one in his senses who is not trained
in medicine would ask health author
tiles for permission to ship in the
virus of bubonic plague to admins
ter to his children, and yet livestock
sanitary officials are asked to give
: permission to swine growers to ship
in hog cholera virus with which to
vaccinate their hogs. Hog cholera is
h just as virulent and dangerous a dis
ease to swine as bubonic plague is
d TO the human family.
In Montana we do not have many
centers of hog cholera infection anC
It if we can keep out diseased hogs anC
is control the use of virus we have elm
IT mated two of the sources by which
m hog cholera infection is general!
carried into a district. Our regula
IS tions prohibit the importation of dis
lie eased and exposed hogs, and I ma,
say that l have known of al
ID actual case of hog cholera bein'
at shipped into the state of Montana.
lr We control the use of virus by on
in regulations in that a Representative
of the livestock sanitary board mus
or supervise the actual vaccination O
re hogs where virus is used, and in &C
dition to this the hogs must be KEY
r. in a hog-tight lot for a period of nc
We less than thirty days after treatmer
and must be disinfected in a 2 De
lie cent solution of a permitted sapon
n fled cresol dip before being release
from quarantine.
Ie- This regulation applies only wheI
virus is used. There are no restri,
W tions where serum alone is used fl
Ill the reason hat the serum is ger
ne free. Where serum alone is used t;
"a, immunity is short-lived, usually on
re several weeks. Where serum ar
en- virus are used simultaneously the in
fl munity is permanent.
in The third source, that of feedir
ip- garbage and table refuse which CO
It'll tains infected pork scraps, is the OF
ese that we cannot positively control, b
1re hog growers themselves can contr
Ill this means of infection very easil
ITO by boiling or sterilizing this slop b
nj fore it is fed to their hogs.
Ill WhCLC II ID lPOSS4DAC
ing ~impracticable to cook or sterilize sic
len then the next safest procedure is
ct double vaccinate the hogs which a
per being fed that garbage. This vacci
AXIS alton, however, must be and shou
ow be carried out under the supervise
use of a representative of the livesto
son sanitary board. We also realize til
lay double vaccination has it's place
hat sanitary control, in that it should
in used in the districts where the dises
era has manifested itself in ~virulent fol
