This sometimes happens in the stallion and is generally due to some injury, as a kick from a mare while in the act of service.
Treatment. - Give a dose of aloes sufficient to open the bowels, and give half-ounce doses of nitrate of potash three or four times a day. Suspend the testicles by placing a bandage around and under the hind quarters; keep cloths wet with hot water inside of the bandage around the testicles. If there is much pain give an ounce or two of laudanum internally and saturate a piece of cotton with fluid extract of lobelia and wrap it around the testicles. Moderate exercise will be beneficial if the testicles are supported.
This is the filling of the scrotum with fluid and is generally the result of prolonged or oft-repeated attacks of inflammation.
Treatment. - Support the testicles with a truss or suspensory and give internally one or two drachms of iodide of potassium. If there is no improvement it may be necessary to puncture the scrotum which will require the skill of a veterinarian.
These are both swollen conditions of the penis. The first is when the penis remains within the sheath, and the second is when it is protruding and cannot be drawn back on account of the swelling; both are due to the same causes, viz.: injuries to the penis or adjacent parts. In the stallion it may be due to kicks during the act of service. It sometimes results from castration in colts.
Treatment. - Bathe the parts freely with warm water and if the penis protrudes support it with a bandage. After the soreness has been somewhat removed by bathing, moderate exercise should be given In very severe cases give nitrate of potash in two to four drachm doses three times a day.
This is an irritation of the membrane covering the penis and lining the sheath. In stallions it generally comes from serving a mare that has an acrid discharge from the vagina, probably from not cleaning properly after foaling. The irritation may be communicated to mares if the horse is allowed to serve while affected. A somewhat similar condition is seen in geldings as the result of foul sheath.
Symptoms. - Small sores will be noticed on the penis from which a slight discharge issues. In mares there will be a discharge from the vagina, and sores will form where it runs down on the outside.
Treatment. - Lay the stallion off from service and wash the penis with cool water, then apply a little of the following three or four times a day with a soft sponge: Sugar of lead, one ounce; sulphate of zinc, six drachms; carbolic acid, two drachms; rain water, one quart; mix.
Do not inject it in the urethra, as the disease rarely extends beyond the orifice, and injections are liable to irritate the deli cate membrane. Severe cases may have a dose of nitrate of potash three times a day.
In mares syringe out the vagina with tepid water and inject the lotion. It is not generally serious and yields readily to treatment in a few days.
