INFECTIOUS DISEASES. 527 
ing of the lungs and the recovery of the animal is hastened. The 
cost of this product, however, at the present time, is exorbitant, and 
it should be considered only in the treatment of very valuable ani- 
mals. 
The same procedure as given for influenza should be carried out in 
the prevention of this affection. 
The diet demands the strictest attention from the outset. In 
many of the fevers the feed has to be diminished in quantity and 
regulated in the quality of its heat-producing components during 
the acute part of the disease, so as to lessen the material for com- 
bustion in the inflamed organs. In edematous pneumonia, on the 
contrary, all the feed that can possibly be digested and assimilated 
must be given. Choice must be made of the richest material which 
can be handled by the weakened stomach and intestines without 
fatiguing them. Good, sound hay should be chopped short and 
dampened or partly boiled; in the latter case the hay tea can be 
reserved to use as a drink. Oats may be preferred dry or in other 
cases are taken better scalded; in most cases, however, it is better 
to give slops of oatmeal, to which may be added a little bran, 
barley flour, or boiled milk and wheat flour. Pure cow’s milk, not 
too rich in fatty matter, may be given alone or with beaten eggs; 
frequently the horse has to be coaxed with the milk diluted with 
several parts of water at first, but will soon learn to drink the pure 
milk. Apples and carrots cut up raw or boiled are useful, and fresh 
clover in small quantities will frequently stinrulate the appetite. In 
other words, various feeds and combinations should be given to the 
horse. Throughout the course of the disease and during convales- 
cence the greatest attention must be taken to cleaning the coat thor- 
oughly so as to keep the glands of the skin in working order, and 
light, warm covering must be used to protect the animal from cold 
or drafts of air. 
STRANGLES. 
Synonyms.—Distemper ; colt-ill; catarrhal fever; one form of shipping fever ; 
febris pyogenica. . : 
Definition.—Strangles is an infectious disease of the horse, mule, 
and ass, seen most frequently in young animals, and usually leaving 
them immune from future trouble of the same kind. 
It appears as a fever lasting for a few days, and is usually associ- 
ated with an abscess formation of lymph glands, especially those 
under the jaw, which have a tendency to break on the outside. It 
usually leaves the animal after convalescence perfectly healthy and 
as good as it was before, but sometimes leaves it a roarer or is fol- 
lowed by the development of deep-seated abscesses which may prove 
fatal.
