Cattle sometimes eats poisonous plants, such as acrid buds of oak, twigs of yew, the water hemlock, and others, and consequently suffer and die. Unless it is known that they have had access to such plants, it is not always easy to determine the nature of the disorder from which they are suffering. If there be suspicion of poisoning, the following treatment may be pursued, when the symptoms seem to indicate it. SYMPTOMS.—Torpor; refusal of food; excessive thirst; distention; the animal shows signs of great agony, grinds its teeth, stamps, paws the ground, strikes its flanks, rolls on the ground, as if with spasms or colic. Sometimes there is great fury, ending in torpor, paralysis, death. TREATMENT.—The stomach-pump should be employed; water thrown into the rumen till vomiting ensues. This should be repeated till the stomach is emptied. In general, however, and unless the animal be very valuable and the circumstances favorable, such means are not available, and you can only give the F.F. and J.K., in alternation, one dose every half hour, or hour, according to the urgency of the case. Eczema Eczema is a disease of the skin and in general appearance is much like mange, but is unlike mange in the fact that it is not caused by parasites, and therefore is not contagious. Several forms of eczema are observed in cattle. 1—An acute form which attacks the legs; there is dullness and loss of appetite, followed by swelling, stiffness and elevated points of hair on the legs. 2—There is a chronic form attacking various parts of the body with loss of hair and crusts. 3—There is still another form caused by eating too much potato pulp, this attacks the legs with redness, swelling, crusts and general loss of condition. Eczema may be told from mange by the absence of the parasites, which in cattle can usually be seen by the naked eye; also in mange the itching is much more intense than in eczema. TREATMENT.—First clean the sores, removing all dirt, scabs, etc. For this purpose, olive oil is better than water, as soap and water are apt to cause further irritation. Apply Zinc Ointment night and morning. Give A.A., three times per day, for two days, then I.I. instead of A.A. Warbles This is often seen on cattle in February and March. It consists of a number of roundish swelling from five to twenty in number, usually on the back and sides. The swellings are sometimes as large as the closed fist. During the summer months the gadfly lays its eggs on the skin of the cattle, especially just above the heels. The cattle bite these places and swallow the eggs; which hatch into larvæ and make their way through the body to the skin, where they form these swellings. The swellings suppurate and form a small hole, through which the larvæ breathe and later escape. After the larvæ have escaped the swellings subside.
