HOG CHOLERA 



Hog cholera was reported from fortj-three counties. Four hundred 

 and eleven droves, consisting of nine thousand, four hundred and 

 sixty hogs and pigs were examined and four thousand, nine hundred 

 and thirty-three were vaccinated. Over three thousand hogs had died 

 in these herds before vaccination was applied and about the same 

 number were found to be too sick to vaccinate. The State has given 

 the serum treatment only in herds where the disease had broken out. 

 Many requests were received to get it done before the disease was 

 observed. This plan was followed because the period of immunity is 

 short, lasts only about two to four months, and serum could not be 

 made fast enough to treat herds already afflicted. The plant at the 

 farm, where the vaccine is made, has been enlarged and perfected to 

 such an extent that it is hoped that the supply in the future will be 

 adequate to keep up with the demand and administer the serum 

 promptly when the disease is first recognized. 



In most cases the diagnosis can be made and tlie serum applied by 

 the local veterinarian. Agents of the Board were sent to sections 

 of the State in which there was no veterinarian, or where he had had 

 no experience with the disease or this form of treatment. The agent, 

 in addition to diagnosing and treating the case, instructed the local 

 man where necessary in the use of the serum. Unusually good results 

 have been obtained in all parts of the State from the use of hog 

 cholera serum. In nearly every case the outbreak has been checked 

 and no further losses sustained after the treatment was applied.
