PITYRIASIS IN CATTLE.
On neck and dewlap; Causes: anæmia, debility, spoiled food, starvation, constitutional predisposition. Symptoms: shedding hair and scales without skin thickening, or itching. Treatment: green soap, tar, creolin, lysol, naphthalin, etc. Alkaline lotions: generally nutritive, succulent food, bitters, iron, arsenic, etc.
This is noticed especially on the neck and dewlap in connection with anæmia, low condition, unsuitable, innutritious and spoiled fodder and a constitutional predisposition. It has the same general characters as in the horse, an excessive production of dandruff or dry scales without any marked change in the thickness of the skin or in its circulation. Treatment consists in the application of green soap, pure or medicated, with tar, creolin, lysol, or other empyreumatic product. Lotions of carbonate or bicarbonate of potash are often effective. Any disorder of digestion, or of the urinary or hepatic functions, or of general nutrition should be corrected, and in most cases, a course of bitters, with iron and arsenic is desirable. A good, indoor hygiene or a run on succulent grass in the open air may be resorted to with benefit.
