_Coryza_ is usually slight and is manifested by sneezing and running
from the nose. It occurs in animals clipped or badly sheltered during
the more inclement seasons. In the worst cases the discharge becomes
persistent and emaciation ensues so that it is necessary to interfere.
Valuable animals may be treated on the same principles as oxen, and in
the case of large flocks by shelter in a warm, dry, cleanly and airy
place and fumigations of steam and the fumes of burning sulphur repeated
daily, together with nourishing diet, such as boiled barley or other
grain, and quarter ounce doses of nitre and common salt.
