Show ERADICATE HOG LOUSE Vigorous and Patient Treatment Is Required. Elood-Sucklng Parasites Cause Much Irritation of Skin In Dipping Creollne Is Better Than Lime and Sulphur. (By N S. MAYO.) The hog louse is a common parasitic pest on swine and one that requires vigorous and patient treatment to eradicate. The hog louse Is one of the largest of the lice that attacks domestic animals. They are readily seen traveling about on the bristles, usually on the neck, back of the ears, moving with a peculiar sliding motion. mo-tion. The eggs or "nits" are small, white, oval bodies attached to the bristles. Hog lice may be found on almost any part of the animal's body, but are most common about the neck, ears and back of the elbow. These are blood-sucking parasites and, by biting the hog and abstracting abstract-ing blood, they cause a good deal of irritation of the skin. The animal rubs on posts and other objects and the coat looks rough and harsh. The parasite and eggs are easily found upon examination. The parasites are transmitted from one animal to another an-other by contact, or by contact with Infected bedding or quarters. Dipping the animals three or four times at intervals of ten days will usually usu-ally free them from these parasites, j Vat for Dipping Hogs. provided the sleeping quarters are .horoughly cleaned and disinfected. ,'n dipping to kill lice, the coal-tar dips of the creoline type are better than lime and sulphur. If the hog wallows are kept well filled with water, wa-ter, to which some of the creoline 3ips are added every ten days, the swine will usually , free themselves from the lice.

These dips should be used warm. There should be a dipping vat on every hog farm. They may be made of wood, galvanized iron or cement. They are set in the ground at a convenient con-venient place so that there is good surface drainage away from the vat. A. good size for a large vat is ten feet long on top, eight feet long on the bottom, bot-tom, and two feet wide on top. The end where the hogs enter should be perpendicular and the other end inclined, in-clined, with cleats, so that the hogs can emerge after swimming through. The entrance should be by a slide. Such a tank is very useful whereever bogs are kept in numbers, as frequent flipping tends to keep the hogs healthy and free from parasites. |
