HOG CHOLERA SERUM. 



A vaccine for the immunization of hogs against hog cholera. Manu- 

 factured by the State of Iowa, under the direction of the State Veterin- 

 ary Surgeon. 



MANUFACTURED UNDER DIRECTION OF STATE VETERINARIAN. 



Chapter No. 151, of the laws of the Thirty-third General Assembly of 

 Iowa, provides for the establishment of a laboratory at or near Des 

 Moines for the manufacture of hog cholera serum. This serum is to be 

 manufactured under the direction of the State Veterinary Surgeon and 

 furnished to applicants within the State of Iowa, with instructions for its 

 use, at cost of manufacture. 



LABORATORY ESTABLISHED. 



The laboratory for the manufacture of this serum has now been 

 established and the serum; will be produced by the same method that 

 is employed by the United States Bureau of Animal Industry. 



VALUE OF SERUM. 



It is to be understood that this is not a cure for hog cholera or swine 

 plague, 'but is intended as a preventive measure in case of an outbreak 

 or where an outbreak is threatened. 



In cases where the disease has had a chance to advance, it is possible 

 that some of the hogs will contract the disease to a fatal extent and 

 develop cholera and die from it before the serum has had time to take 

 effect, so it is very important that the treatment should be applied as 

 early as possible in case the disease makes its appearance. 



SHOULD BE VACCINATED. 



When the disease makes its appearance in a herd or in the neighbor- 

 hood, all the well hogs should be vaccinated, and all the sick hogs should 

 be destroyed and burned, and should any of the vaccinated hogs develop 

 cholera, they too should be destroyed and burned. This will prevent, 

 to a certain extent, the spread of infection. Diseased hogs should be 

 removed from the public highway and the pens and enclosures thor- 

 oughly cleaned and disinfected. Hogs should be kept in dry pens; dogs 

 should be kept tied, as they may carry the disease. Wagons or hog racks 

 used to remove the dead hogs must not be taken onto a neighbor's prem- 

 ises. Only the one whose duty it is to feed and care for the diseased 

 hogs should be allowed near the pens; this attendant to keep away from 

 neighbor's hog pens or enclosures. 



THINGS TO BE REMEMBERED. 



As a preventive measure when the disease appears in the neighbor- 

 hood the following precautions should be observed: 



Keep your dog tied up, as it might carry infection.
