CAUSE: Injuries. Horses working on rough stony roads are subject to punctures, pricks, bruises, corns, treads, etc., which end in pus formation which does not get a pendant opening and destroys the tissues with which it comes in contact. Finally it bursts, forms sinuses and pipes, as commonly called, at the top of the hoof. SYMPTOMS: Extreme lameness, heat, pain and swelling will show themselves about the top of the hoof. As a rule a Quittor develops slowly and is more or less painful during the first stages. After the sinus is formed and the pus discharges, the inflammation generally subsides. Its healing process is often delayed due to the diseased portion of the cartilages inside the horny hoof. TREATMENT: Apply Flaxseed or hot Bran poultices to relieve the inflammation and hasten the formation of sinuses or pipes. Then with an ordinary syringe inject the following: Silver Nitrate, ten grains; Water, one ounce. Inject fifteen to twenty drops twice daily. Keep the food clean and the animal as quiet as possible. It is very disagreeable, as stated before, and the healing is very slow, but this must be naturally expected, as we are unable to provide the sinuses with good drainage. RED WORM (Strongylus Tetracanthus) The Red Worm varies in length from one-third to three and one-quarter inches, and is sometimes white though it usually appears to be red because of the blood it contains. This parasite is found in all parts of the world. Its favorite haunt is marshy land. SYMPTOMS: Paleness of all visible membranes, eyes watery and inflamed, swelling of the sheath, legs, and lower surface of the belly; fetid diarrhoea, dullness, debility, emaciation, rough coat, and the presence of worms in the feces. The worms when first passed are bright red in color but after being exposed to the air they turn dark and may easily escape the notice of the casual observer. TREATMENT: Withhold all food for twenty-four hours, then place the following drugs in a gelatin capsule: Calomel, two drams, Barbadoes Aloes, three drams; Ferri Sulphate, two drams. Give with capsule gun. Also place the following tonic in their feed: Pulv. Quassia, one ounce; Ferri Sulphate, two ounces; Pulv. Anise Seed, two ounces. Mix and make sixteen powders. Give one powder two or three times a day in the feed. RHEUMATISM CAUSE: Exposure to cold rains, drafts, lying on damp ground when the blood is in poor condition. Also due to over-stimulating food. SYMPTOMS: Lameness, swelling or soreness which may shift from one place to another, then finally locate in or near one of the joints of the limbs.
