SYMPTOMS: The animal's general health is affected as is evident from the morbid state of his appetite, rough coat, pot-belly, liability to colic and slight diarrhoea. Some of these worms are often expelled with the feces. As they increase in number, they block up the small intestines, giving rise to colic, and may in time kill the horse. They sometimes cause perforation of the bowels. TREATMENT: Withhold all food from eighteen to twenty-four hours, then administer the following: Ferri Sulphate, two drams; Antimony Tartrate, two drams; Pulv. Quassia, two drams. Place in gelatin capsule and give with capsule gun. Follow this from six to eight hours with Aloin, two drams; Ginger, two drams, and give as above directed. It is a good plan to repeat the above treatment in ten days to insure the removal of any worms which may have survived the first treatment. SCROTAL RUPTURE (Inguinal Hernia) CAUSE: Abnormal size of the upper ring through which a part of the intestines or its connecting membrane descends into and through the canal leading from the abdomen to the scrotal cavity. There is little danger of strangulation from this form of rupture which may occur at birth and disappear with age. A careful examination should therefore be made of the scrotum before castration. SYMPTOMS: In most cases, this condition is easily detected. The scrotum will be somewhat enlarged. Sometimes the intestines will become strangulated and colicky symptoms appear. When a young male colt shows signs of colic, examine him for Scrotal Rupture. TREATMENT: The trouble usually disappears with age although in some cases it is well to operate. Where colicky symptoms are present, roll the colt on its back, manipulating the scrotum. Diet carefully. SHOE BOIL (Capped Elbow) CAUSE: Injuries, bruises or pressure when lying on a rough floor. Sharp heeled shoes and kicks also have a tendency to produce it. SYMPTOMS: A hot painful swelling of the Elbow joint when first noticed. When neglected, it takes on a white fibrous or callous growth. TREATMENT: First remove the cause. Do not lance the enlargement; let it come to a head of its own accord, by applying Red Iodide of Mercury, two drams; Pulv. Cantharides, three drams; Lard, two ounces. Mix well together and apply twice a week. When the swelling is hot and painful it is well to apply cold water or ice packs before applying the above mentioned prescription. SPLINTS CAUSE: This disease is chiefly produced by trotting or running on hard ground, etc. It is evident that horses with high knee action and heavy bodies are more liable to this disease. Jumping is also a common cause of splints, but the more accustomed a horse is to jumping the less liable he is to throw splints, because practice teaches the animal to regulate his movements so as to more or less diminish the disagreeable if not actually painful effect of concussion.
