internal cold caused by drinking ice water or eating frozen feed, may cause
it. The infectious forms of enteritis are caused by germs and ptomaines in
the feed. Drinking filthy water or eating spoiled, mouldy feeds are common
causes. In cattle pasturing in low, marshy places, enteritis may be common.
The toxic form is caused by irritating poisons, such as caustic acids,
alkalies and meat brine.

_In the mild form of enteritis_ the appetite is irregular, the animal acts
dull and stupid and may be noticed lying down more than common. Slight
abdominal pains occur, especially following a meal. An elevation in the
body temperature may be noted and the animal may drink more water than
usual. Constipation or a slight diarrhoea may be present. The feces may be
soft and foul smelling, coated with mucus, and slightly discolored with
blood.

_In the severe form of enteritis_ pressure on the abdomen may cause pain,
the respiration and pulse beats are quickened and the body temperature is
elevated. The abdominal pain may be severe and the animal is greatly
depressed or acts dull. The movement of the intestines is suppressed at
first and constipation occurs. Fermentation and the formation of gas may
take place. Later the intestinal peristalsis increases and a foul-smelling
diarrhoea sets in that is often mixed with blood. In the toxic form there
may be marked nervous symptoms. Spasms, convulsions, stupefaction and coma
may be manifested.

In the mild form recovery usually occurs within a few days. The more
serious forms of the disease do not terminate so favorably. In the toxic
form death usually occurs within a few days.

The large majority of cases of enteritis can be prevented by practising the
