Show Control Hog Cholera by Preventive Meang Hog cholera has no cure and must be controlled by prevention. The disease dis-ease is caused by an organism which can live a year or two outside of the animal's body. These organisms are found in almost all tissues of, and in all discharges from, the body of the diseased, hog. Cholera may be spread in many ways. The germ may be carried car-ried on one's shoes or by animals, in Infected straw or litter, or streams of water. All dead hogs should be burned or buried deeply. Do not go near a neighbor's sick hogs ; they may have cholera. Vaccination prevents the disease. When vaccination is properly performed per-formed the animal passes through a mild attack or form of cholera which immunizes it against the disease for life. A small amount of virus, injected in-jected into the pig causes the disease, At the same time, enough hog cholera serum is injected to protect the animal against the disease. |
