STAGGERS.
(Forage Poisoning—Inflammation of the Brain)
(Cerebral Meningitis)
Cause.—Certain plants or stagnant water are most commonly instrumental in producing staggers; frequently seen in the early autumn months when the grass in the pastures becomes dry and certain forage remains green which contains toxic principles. These plants are ravenously eaten by horses on account of being green and tender. This is one of the common causes of the disease, although moldy, indigestible or highly nitrogenous foods are frequently productive of staggers. This form of staggers is not contagious, although what produces staggers in one horse will also produce it in another. In this way several horses may become affected with staggers at the same time. Inflammation of the brain may occur as a complication of some infectious or digestive disease. Other causes are blows on the head, tumors in or on the brain, which naturally cause the animal to stagger, as the brain controls the horse’s power of locomotion.
Symptoms.—These vary to a certain extent, but a careful observer will detect some trouble connected with the nervous system, as the animal walking unsteadily, stepping high and keeping the legs spread apart, bracing itself to keep from falling. There is also great depression, dullness and sleepiness with little or no inclination to move about. The head may be placed against a wall or fence and the legs kept moving as if the horse were trying to walk. As the disease progresses and no attempts are made to relieve it, they will become fractious, nervous, easily excited, pawing and eventually fall, keeping the feet moving as if walking, throwing their heads about in a delirious manner and eventually death follows. The horse as a rule eats and drinks ravenously when the first signs of staggers are noticed, but in its latter stages the tongue and gullet become paralyzed and although the animal attempts to eat and drink he cannot swallow. The pulse varies. It is strong, but subnormal when the first symptoms of staggers are noticed, that is to say, it is as slow as twenty to twenty-five beats per minute. As the disease progresses, however, it becomes weaker and faster. Constipation frequently accompanies this disease, also paleness tinged with yellow about the mucous membranes of the mouth and eyes. In many instances I believe that the poisonous forage eaten by horses depresses the heart action to such an extent that it results in the brain not receiving the proper blood supply, causing dizziness or staggers.
Treatment.—Place the animal in a clean, dark stall, keeping the surroundings as quiet as possible. In its first stages it is easily treated, but as the horse becomes easily excited and his swallowing becomes difficult, treatment becomes more difficult. When the first signs are noticed, administer a physic as: Aloin, two or three drams; Ginger, two or three drams, according to the size of the animal. Place in gelatin capsule and give with capsule gun. This physic removes the irritant from the intestines and prevents its absorption into the blood. Also administer the following: Bromide of Potassium, twelve ounces; Nitrate of Potash, four ounces; Iodide of Potash, three ounces. Make into twenty-four capsules and give one capsule every four hours.
My method of administering medicine to animals places me in a position to treat them and compel them to take the medicine even though paralysis may exist. When animals will eat, feed food that is easily digested, as hot wheat bran mashes, steamed rolled oats and vegetables and give small quantities, but not often, of clean fresh water. It is necessary to give stimulants and tonics as soon as they are on the road to recovery, as Pulv. Nux Vomica, four ounces; Pulv. Gentian Root, four ounces; Sulphate of Iron, two ounces. Make into sixteen capsules and give one capsule three times daily.
