The digestive function first fails, when the secondary or low state of fever comes on. The food undischarged ferments; the stomach and intestines are inflated with gas, and swell rapidly. The nervous system is also attacked, and the poor beast staggers. The hind extremities show the weakness; the cow falls, and cannot rise; her head is turned on one side, where it rests; her limbs are palsied. The treatment in this stage must depend on the existence and degree of fever. The pulse will be the only true guide. If it is weak, wavering, and irregular, we must avoid depleting, purgative agents. The blood flows through the arteries, impelled by the action of the heart, and its pulsations can be very distinctly felt by pressing the finger upon almost any of these arteries that is not too thickly covered by fat or the cellular tissues of the skin, especially where it can be pressed upon some hard or bony substance beneath it. The most convenient place is directly at the back part of the lower jaw, where a large artery passes over the edge of the jawbone to ramify on the face. The natural pulse of a full-grown ox will vary from about forty-eight to fifty-five beats a minute; that of a cow is rather quicker, especially near the time of calving; and that of a calf is quicker than that of a cow. But a very much quicker rate than that indicated will show a feverish state, or inflammation; and a much slower pulsation indicates debility of some kind. Next in importance, as we have already stated, is the physic. The bowels must be opened, or the animal will fall a victim to the disease. All medicines should be of an active character, and in sufficient quantity; and stimulants should always be added to the purgative medicines, to insure their operation. Ginger, gentian, caraway, or red pepper in powder, may be given with each dose of physic. Some give a powerful purgative, by means of Epsom salts one pound, flour of sulphur four ounces, powdered ginger a quarter of an ounce, all dissolved in a quart of cold water, and one half given twice a day till the bowels are opened. The digestive organs are deranged in most forms of milk fever, and the third stomach is loaded with hard, indigestible food. When the medicine has operated, and the fever is subdued, little is required but good nursing to restore the patient.
