Is NOT RESPONSIBLE

blood spots. Ulcers frequently occur
IN the first part OF the large intest-
ines, and if swine plague is present
! pneumonia is constant symptom.
In contagious swine pneumonia,
solid Jumps or areas of lungs are
all that autopsy reveals, except occa-
sionally ulcers in mouth and throat.
No blood spots are present in any
part OF the body.
Swine pneumonia is an infectious
disease. That is, it is caused by an
organism which produces the disease
when it finds itself located in the
body of suitable animal. In a herd
of hogs this organism spreads rapidly
from one animal to another until all
are likely to suffer if some measures
to combat it are not employed. 1t
may be carried from place to place by
insects, birds, dogs, or persons who
pass through diseased pens or pas
lures. This shows the inadyisability
of visiting herds of animals sick
from any cause. Regarding the
treatm ent of these diseases it has
been found that internal medication
is useless, and preventive measures
offer the only hope of escape from
them. The hog cholera serum treat
ment recently advised has given
very satisfactory results. Two meth
DDS are employed: one is the use of
protective serum alone, which af-
fords protection for d period of sew,
eral weeks. Its use is advised when
hog cholera already exists in a herd
as the animals will be exposed to the
disease By close contact with the sick
ones, and the serum will protect
them from fatal attack. In the very
early stages of the disease the serum
has a curative effect, but is not gen
orally used for this purpose, and its
value is chiefly as protecting agent.
BY another method one for produc-
ing lasting immunity the serum and
hog cholera virus are injected at the
same time, the virus causing the dis
ease and the serum protecting the
animal from a fatal attack. This at
fords a lasting immunity but on ac-
count of the danger of spreading the
disease the virus should be used with
caution, and only by men accustomed
to such work
Hog cholera serum costs about two
cents per cubic centimeter and the
usual dose for protection is about 40
cubic centimeters per hundred
pounds body weight, making cost
of about so cents per hundredweight
of the animal.
No protective serum or biological
specific has been prepared for use in
the case of contagious pneumonia,
and for its control we have to rely en-
tirely on sanitary measures, as in
cases of all serious infectious dis
eases.
When any contagious disease of
serious nature starts in a herd, the
exact disease should first be ascer-
tanned. If it is contagious pneu
monia first isolate all sick animals
and take the healthy ones and put
them in a clean lot or pasture, after
running them through shallow tank
of suitable disinfectant-five per
cent solution of cresol or creolin is
very good If the pigs are muddy
they should be driven through tank
of water first to get their feet and
legs quite clean. Keep the healthy
hogs in clean dry place and watch
them closely and if any show signs of
sickness they should be removed at
once.
The sick animals may be left in
the former quarters if they are thor
oughly disinfected. The fences, earth
and hog houses should be thoroughly
soaked with five per cent solution
of cresol, after all litter has been re-
moved and burned Lime spread
about on the ground is a valuable
permanent disinfectant, but should
be covered with clean straw in the
houses as the animals must not be
forced to inhale the fine lime dust.
If strict sanitary measures are re-
sorted to the losses may be reduced
to a minimum and these measures
offer the only method of combating
contagious swine pneumonia that is
known at present.
