AZOTURIA, OR MONDAY MORNING DISEASE.
—This is a very peculiar affection of the horse, in which the animal shows a special form of lameness upon exercise, after having remained idle for a day or two. The cause is not definitely known, and yet the circumstances under which the disease develops are rather constant, such, for instance, as an animal in vigorous condition, fed liberally upon nitrogenous feed, remaining idle over Sunday, a holiday or at other times. Upon being taken out the following morning the animal usually shows an excess of energy, but before going far begins to go lame in one or both hind limbs until, if urged further, becomes completely paralyzed behind, going down and unable to rise. He also shows considerable pain, as though he might be suffering from some form of colic, with a profuse sweating. On reaching this point the animal usually ceases to void the urine, which, when drawn, appears a very dark brown or coffee color. The pulse and breathing are somewhat accelerated, and frequently there is considerable nervous excitement. The muscles of the loin and thigh are tense and rigid.
The treatment should begin as soon as the lameness shows itself. After a few hours of rest, the distress will be over. The more exercise given the animal after the lameness begins, the more severe the trouble, and the more energetic means of treatment required. In a case showing signs of nervous excitement, it should receive 2 tablespoonfuls of bromide of potassium every three or four hours until becoming quiet. Sweating should be induced by blanketing the animal well, preferably using blankets wrung out of hot water and covered with a dry one. Allow all the water the animal will drink and give it 4 tablespoonfuls sweet spirits of niter three times a day if bladder is not paralyzed. If unable to void the urine, the bladder must be emptied three times daily. A laxative or purgative should be given early in the disease. If the animal remains somewhat stiff, give a teaspoonful in the feed twice a day of the following: Powdered nux vomica, 4 teaspoonfuls; powdered sulphate of iron, 6 teaspoonfuls; powdered gentian root, 6 teaspoonfuls.
