be removed from straw or hay. Feeds known to be dirty should be run through
a fanning mill before feeding.

INFLAMMATION OF THE STOMACH OF SWINE.--Overloading and feeding spoiled feed
are _common causes_ of inflammation of the stomach. Swill-fed hogs are most
commonly affected with this disorder. Overloading more often results in an
inflammation of the stomach if the overloading follows the feeding of a
light ration, and the weather is extremely warm. Hogs that are accustomed
to eating salt may eat too much of it when fed to them after it is withheld
for a week or longer, and a large quantity of water is taken soon
afterwards. Slop containing alkaline washing powders and soaps irritate the
stomach and intestines and cause a serious inflammation.

_The symptoms_ are loss of appetite, restlessness and sometimes colicky
pains. The hog usually wanders off by itself, acts dull, grunts, lies down
in a quiet place or stands with the back arched and the abdomen held tense.
Vomiting commonly occurs. Sometimes the animal has a diarrhoea. The body
temperature may be above normal.

_The treatment_ consists in avoiding irritating feeds and sudden changes in
the kind or quantity of feed fed. Drenching with hot water, or with about
one ounce of ipecacuan may be practised. From one to three ounces of castor
oil, depending on the size of the hog, may be given. After recovery the
hogs should be confined in a comfortable pen and fed an easily digested
ration.

DISEASES OF THE INTESTINES

GENERAL DISCUSSION.--The intestinal tract of solipeds is the best developed
of any of the domestic animals (Fig. 14). It is divided into two portions,
