characterized by fermentation and collections of gas in the intestine there
is gastric tympany as well.

Acute indigestion characterized by _impaction_ of the large intestine
pursues a longer course than the forms just mentioned, and the abdominal
pain is not severe.

_Congestion and inflammation_ of the intestine may result from the
irritation produced by the feed. When this occurs, the abdominal pain is
less violent. The animal usually acts dull, the walk is slow and unsteady,
and the respirations and pulse beats may be quickened.

A large percentage of the cases of acute indigestion terminate fatally. The
course of the disease varies from a few hours to several days.

_The treatment_ is both _preventive_ and _curative_. The preventive
treatment is by far the most important. This consists in observing right
methods of feeding and caring for horses. The attendant should note the
condition of the animal before feeding grain, feed regularly and avoid
sudden changes in feed. If a horse has received unusual exercise, it is
proper to feed hay first, and when the animal is cooled out, water and feed
grain. Drinking a small quantity of water when tired or following a meal is
not injurious, but a large quantity of water taken at such times is
injurious and dangerous to the health of the animal. The feeding of spoiled
or mouldy feeds to horses is highly injurious.

The horse should be given a roomy, comfortable stall that is well bedded,

exercise usually aggravates the case and may cause congestion and
