Hog Cholera and Swine Plague.
[By C. F. DAWSON, Station Veterinarian.]
Hog cholera and swine phigue are by far the most com-
mon diseases of swine. The former primarily attacks the
intestines and secondarily the lungs, while the latter
attacks the lungs first and may secondarily affect the
digestive tract. Each has its specific cause. The germ
of hog cholera can live for months in the soil, regardless
of the character of the climate. The swine-plague germ.
on the other hand, rapidly perishes in the soil and
retains its vitality by getting into the mouths and throats;
of healthy animals. In most outbreaks of so-called hog
cholera, we find these diseases co-existing.
Hog cholera may be of two kinds. It may run an acute
course and destroy a large number in a few days, or it.
may become chronic and last for months. In the acute
type there will be no ulceration of the intestines, the
blood being the main organ affected.
In the chronic type the losses are not so severe. The
symptoms are more pronounced, and it is probably this
form which is best known to breeders. As symptoms,
there are dullness, shivering, loss of appetite, thirst,
fever and redness of the skin inside the thigh and along
the belly. In a few days this redness assumes a purple
or violet color. A rash appears, as spots of a dark-red or
brownish color, which attain the size of a silver dollar.
The tongue is covered with a brownish fur. The animal
grunts and screams when handled. It moves feebly, is
unsteady in gait and has a plaintive cry. Frequently a
cough, which is hard and barking, lasts throughout the
disease. Vomiting may be present. When constipation
persists, the outbreak is unusually fatal. Generally, the
bowels loosen by the third day and the diarrhea is pro-
fuse, black in color and foul-smelling. The pulse now
becomes quite frequent and feeble, and the cough is pain-
ful and exhausting. Weakness increases till the animal
gets down and is unable to rise. In some cases swellings
appear, and lameness is a notable symptom.
As to treatment, the following powder compound has,
in my experience, given good results. It not only cures
many cases, but will, in a large degree, prevent its spread.
It costs very little-only about 15 cents a pound when
bought in fifty-pound quantities, or about 1 cent a day
to medicate each hog.
The formula and the directions for its use are as
Wood charcoal, 1 pound; sulfur, 1 pound; salt, 2
pounds; bicarbonate of sodium, 2 pounds; sulfate of
sodium, 1 pound; hyposulfite of sodium, 2 pounds; sul-
fide of antimony, 1 pound. Mix these thoroughly and
give one tablespoonful to each 200 pounds of weight of
hog once a day in'soft feed.' In the case of animals that
are too sick to eat, dissolve the proper dose in water and
pour slowly -with frequent pauses-small quantities
into the mouth between the cheek and teeth, allowing the
animal to lie on its side or belly.
