SIMPLE ENTERITIS.

[See Gastroenteritis, p. 33.]

CROUPOUS ENTERITIS.

Under certain conditions, severe irritation of the digestive canal may, in
cattle, cause a form of inflammation of the intestines (enteritis) that is
characterized by the formation of a false membrane upon the surface of the
lining membrane of the intestines, particularly the large ones.

_Symptoms._--There is fever, depression, loss of appetite, diarrhea, and in
the fecal masses shreds of leathery false membrane may be found. These
shreds are sometimes mistaken for parasites or for portions of the wall of
the intestine.

_Treatment._--Give a pound of Glauber's salt, followed by bicarbonate of
soda in doses of 2 ounces four times daily.

ENTERITIS (OBSTRUCTION RESULTING FROM INVAGINATION, OR INTUSSUSCEPTION,
TWISTING, AND KNOTTING OF THE BOWELS).

Inflammation may arise from a knot forming on some part of the small
intestine from the portion of the bowel becoming twisted on itself, or from
one part of the bowel slipping into another, which is termed invagination.
This form of enteritis occurs occasionally in animals of the bovine
species.

_Causes._--The small intestine, which in the ox rests on the right side of
the rumen, is, from the position which it occupies, predisposed to this
accident. It has been ascertained that animals which have shown symptoms of
this malady have trotted, galloped, or made other violent exertions in
coming from drinking, or that they have been chased by dogs or by animals
of their own species while at pasture. The accident is most likely to occur
among cattle on very hilly pastures. The danger of jumping or running is
greatest when the rumen is distended with food.

_Symptoms._--This form of enteritis or obstruction is manifested by severe
colicky pains; the ox scrapes and strikes the ground with his front and
hind feet alternately; keeps lying down and getting up again; he keeps his
tail constantly raised and turns his nose frequently to his right flank; he
is frequently bloated, or tympanitic, on that side. He refuses feed and
does not ruminate, and for some hours suffers severe pains. At first he
frequently passes thin dung, and also urinates frequently, but passes only
a little urine at a time. On the second day the pains have become less
acute; the animal remains lying down; moans occasionally; his pulse is
small and qu
