Show CRUDE OIL WILL ERADICATE MANGE j Water in Wallow Covered With Heavy Film. j Mange, which has been reported as j infesting hogs in several localities, i may be 'rented most effectively by up-, plications of crude petroleum, fuel oil, ! coal-tar dip or lim -and-sulphur dip, says Dr. R. F. Rourne of the veter- j inary department of the Colorado Ag- I ricultural college. "The methods used in applying sucb preparations Include dipping, spraying, spray-ing, hand dressing or the use of medicated med-icated wallows," Doctor Rourne says. "Cement wallows which provide for j three or four inches of liquid with allowance al-lowance for a rise in level when tha pigs nre occupying them, have proved satisfactory in warm weather. Wallows Wal-lows should be charged with water only until the pigs become accustomed, to using them. Then, for a day or I two. the water may be covered with a heavy film of crude oil. This routine should he repeated as often as necessary neces-sary to control the disease. "Wallows should be in a shaded place to avoid the water becoming too warm to be inviting. Spraying ! with fuel oil or applying It with a ' garden sprinkling can, in which the j openings have been enlarged, often j gives relief at less expense. j "Mange in hogs resembles itch or i mange in other animals, and Is caused by a similar minute mite which lives j exclusively upon and within the skin j of hogs, although sometimes - tem- I porarily affecting other animals and man. The females measure only about j one-fiftieth of an inch in length while ' the males are still smaller. ' "The female burrows into the skin and travels for a considerable distance dis-tance under the surface by excavating a tunnel within which her eggs are deposited. de-posited. This migration causes intense itching and results in much scratching and rubbing, which together with the , direct effects of the invasion, causes loss of hair, thickened, inflamed, and often furrowed and scabby lesions of the skin. "The . condition spreads to other hogs by contact and probably also by infested pens, the mites being able to live away from their host for several weeks. In some cases the progress of the disease is rapid and the effects severe, while in other instances the disease is only mildly irritating and spreads slowly. It is usually most noticeable no-ticeable in unthrifty animals or In those kept in unsanitary, crowded quarters." |
