A very light ration should be fed and an intestinal antiseptic given with
the feed. A thin slop of shorts is usually preferred. Four ounces of
pulverized copper sulfate may be dissolved in one gallon of hot water, and
one quart of this solution may be added to every ten gallons of drinking
water and slop. Water and slop should not be left in the troughs for the
hogs to wallow in. The troughs should be disinfected and turned bottom side
up as soon as the hogs have finished feeding and drinking. Kitchen slop and
sour milk should not be fed. The care and treatment of the herd require
work and close attention on the part of the attendant. Indifferent,
careless treatment is of no use in this disease.

A disinfectant should be sprayed or sprinkled about the feed troughs,
floors, pens and sleeping quarters daily.

DISPOSING OF DEAD HOGS.--The carcasses of the dead hogs should be burned.
Before placing the carcass on the fire, it should be cut open and several
long incisions made through the skin. A crematory may be made by digging
two cross trenches that are about one foot deep at the point where they
cross, and shallow at the ends. Iron bars or pipe may be laid over the
trenches where they cross for the carcass to rest upon, or woven wire
fencing securely fastened with stakes may be used in the place of the iron
bars. If the carcass is disposed of by burying, it should be buried at
least four feet deep and covered with quicklime.

DISINFECTING THE YARDS AND HOUSES.--If the sick hogs are moved to new
quarters at the beginning of the outbreak, the hog houses and yards should
be cleaned and disinfected (Fig. 84). The manure and all other litter
should be hauled away to a field where there is no danger from this
