This often occurs to pigs that have travelled any distance: the feet
often become tender and sore. In such cases, they should be examined,
and all extraneous matter removed from the foot. Then wash with weak
lie. If the feet discharge fetid matter, wash with the following
mixture:--
Pyroligneous acid, 2 ounces.
Water, 4 ounces.
In the treatment of diseased swine, the "issues," as they are called,
ought to be examined, and be kept free. They may be found on the inside
of the legs, just above the pastern joint. They seem to serve as a
drain or outlet for the morbid fluids of the body, and whenever they are
obstructed, local or general disturbance is sure to supervene.
