Show IMMUNIZE PIGS PROMPTLY IN CHOLERA TERRITORY In communities where hog cholera existed during the winter, particularly in the North, says a statement from the Bureau of Animal Industry, United Unit-ed States department of Agriculture, hogs that died from the disease very likely were left unburied, perhaps covered cov-ered with snow. Frozen ground makes mak-es it a difficult task to bury carcasses, and owners sometimes defer this work till the snow has melted and the frost is out of the ground. In the meantime, mean-time, new litters farrowed on the premises, as well as other susceptible hogs brought in from outside sources, are in danger of taking cholera from the infection thus scattered. All susceptible swine on such premises prem-ises should be immunized. There is always a possibility of infection being present in hidden places to which cholera-sick hogs have had access, thus constituating a source of danger, even after the dead hogs have been properly disposed of. In short, where hog-cholera infection is known to exist, ex-ist, the Federal specialists say, prompt attention should be given to the immunization of the herd. It is rot always safe to rely on ability to keep hogs away from places where infection in-fection may lurke. Once the serum and virus used in preventing cholera have been properly administered the owner may rest assured that his hogs are immune and will not contract the disease. |
