floor, and the bed
itself will be always clean.

In addition to cleanliness, close attention should be given to the feed
which is supplied, that nothing may be fed which will convey the germs
of disease, especially tuberculosis, to the herd. If the hogs are fed
milk in any form obtained from cows kept upon the same farm, the cows
should be subjected to the tuberculin test, as by this means all
tuberculous milk may be kept from the hogs. If they run with the cattle
of the farm a tuberculin test of all the cattle is none the less
desirable. Animals dead from any disease should not be fed to the hogs
until the meat has been made safe by cooking. Skim milk or refuse from a
public creamery should not be fed to hogs until it has been thoroughly
sterilized.

Feeding and drinking places should be clean and the water supply pure.
Unless the origin is known to be uncontaminated and there has been no
possibility of infection during its course, hogs should not be allowed
access to any stream. Wallows should be drained out or kept filled up as
much as possible. At least once a month the quarters should be
disinfected with a solution of Pratts Dip and Disinfectant. These
precautions will be found valuable aids in the destruction of the
various animal parasites, as well as a protection from some more serious
troubles.

The methods of feeding and management outlined above have been
successfully followed by hog growers for many years. They are
conservative and safe. But during recent years a new method of feeding
has been developed and is being generally adopted, especially by
specialists who make hog growing a real business. This is known as the
"self-fed" plan, under which system feed is kept before the hogs at all
times and they are permitted to eat at will. In poultry feeding this is
called "the dry mash system."

Just who deserves credit for originating or developing this plan cannot
be stated. That it is a good one is evidenced by the fact that it has
received the endorsement of the Bureau of Animal Industry, United States
Department of Agriculture; of many Agricultural Experiment Stations; of
the specialty swine journals; of practical hog breeders in all sections
of the country.

For this self-feed plan it is claimed that both feed and labor are
saved, thus reducing production costs. That a 250-pound hog can be grown
in thirty days less time than is possible where slop-feeding is
practiced, thus getting the hogs to market
