Milk fever may be induced by the hot drinks often given after calving. A young cow at her first calving is rarely attacked with it. Great milkers are most commonly subject to it; but all cows have generally more or less fever at calving. A little addition to it, by improper treatment or neglect, will prevent the secretion of milk; and thus the milk, being thrown back into the system, will increase the inflammation. This disease sometimes shows itself in the short space of two or three hours after calving, but often not under two or three days. If four or five days have passed, the cow may generally be considered safe. The earliest symptoms of this disease are as follows: The animal is restless, frequently shifting her position; occasionally pawing and heaving at the flanks. Muzzle hot and dry, the mouth open, and tongue out at one side; countenance wild; eyes staring. She moans often, and soon becomes very irritable. Delirium follows; she grates her teeth, foams at the mouth, tosses her head about, and frequently injures herself. From the first, the udder is hot, enlarged, and tender; and if this swelling is attended by a suspension of milk, the cause is clear. As the case is inflammatory, its treatment must be in accordance; and it is usually subdued without much difficulty. Mr. Youatt says, “The animal should be bled, and the quantity regulated by the impression made upon the circulation,--from six to ten quarts often before the desired effect is produced.” He wrote at a time when bleeding was adopted as the universal cure, and before the general reasoning and treatment of diseases of the human system was applied to similar diseases of animals. The cases are very rare, indeed, where the physician of the present day finds it necessary to bleed in diseases of the human subject; and they are equally rare, I apprehend, where it is really necessary or judicious to bleed for the diseases of animals. A more humane and equally effectual course will be the following: A pound to one and a half pounds of Epsom or Glauber’s salts, according to the size and condition of the animal, should be given, dissolved in a quart of boiling water; and, when dissolved, add pulv. red pepper a quarter of an ounce, caraway do. do., ginger do. do.; mix, and add a gill of molasses, and give lukewarm. If this medicine does not act on the bowels, the quantity of ginger, capsicum, and caraway, must be doubled. The insensible stomach must be roused. When purging in an early stage is begun, the fever will more readily subside. After the operation of the medicine, sedatives may be given, if necessary.
