INFECTIOUS ABORTION IN MARES.

no thriving, the hair looked dead and rough, the animal it¬ 
self having little life and scarcely any vitality. 
Course and Determination .—The mares, after inoculation 
r 7 J 
abort in about fifteen to twenty days. The foals born alive 
from inoculated mares invariably die, though some live for 
two or three months. 
Treatment-prophylactic. — In regard to the treatment of 
mares having aborted, the following measures should be fol¬ 
lowed : 
1. If the mare aborted in an open paddock or pasture, the 
foetus and foetal membranes should be burned, and the mare 
taken to a stable or small lot where she can be easily treated. 
2. If the mare is removed to a stable, it must be apart 
from any other stable containing pregnant animals,- and must 
not be on high ground, the urine of which will run into lots, 
paddock, or field occupied by pregnant animals ; if removed 
to a small lot, the lot must be low or situated in such a place 
that no pregnant animals will by drainage be exposed to the 
germs causing the trouble. 
3. (This third measure is only necessary in mares that have 
aborted and are not doing well). The external parts should 
be thoroughly cleansed with a solution of hydrargyrum bi¬ 
chloride (corrosive sublimate), 1 part to 1,000 parts of water. 
The tail itself should be thoroughly washed with the same, or 
if in fly-time, a solution of carbolic acid may be supplemented 
to the corrosive sublimate, of the strength of one part of acid 
to 100 parts of water. This having been done, the vagina 
and uterus should be thoroughly cleansed with injections of 
pure tepid water. After this, use the solution above men¬ 
tioned for injections per vagina. Continue these injections 
once a day for two or three days. 
4. The attendant treating mares should thoroughly disin¬ 
fect his hands, and if possible change his clothing before he 
goes into the presence of pregnant animals. 
5. The mares after two or three weeks of treatment may 
be allowed to the stallion with safety, 
6. The foals affected with joint-ail (it being the same dis¬ 
ease differently manifested and capable of producing abor¬ 
tion) should be destroyed, and their carcasses burned.
