would aid the animals in getting rid of the disease. It would be 

 well, if possible, to change your yards occasionally and not keep 

 the hogs on one yard too long. Plow the yard and put to some 

 good forage crop in the proper season, as this is an excellent feed 

 for hogs, and you no doubt have heard said: "Pastureless pigs 

 are neither the most profitable nor the most resistant to preva- 

 lent diseases." Give good, wholesome food yet not too much. 



A few "don'ts" to be observed in combating hog cholera: 



Don't allow your hogs to run at large and carry infection 

 from the infected farm to those that are free from disease. 



Don't leave the dead carcasses exposed for the crows and 

 buzzards to feed upon and then carry the infection to your 

 neighbor. 



Don't throw the dead animals into a near-by stream be- 

 cause it is handy. This will only carry the infection to your 

 neighbors below you. 



Don't allow your diseased animals to run all over your farm 

 and keep the entire place infected; shut them up and keep the 

 infection localized in one place on your farm if you are so unfor- 

 tunate as to get it. 



Don't allow your hogs to run to the creek during a cholera 

 outbreak; there is danger of getting infection in this way. 



Don't bury an animal that has died of cholera, as this only 

 harbors the infection and may cause you and your neighbors 

 trouble next year. 



Don't ask your neighbor to help you haul your diseased hogs 

 to market; this scatters infection. 



In controlling hog cholera we must remember there is no 

 effective cure for the disease after it is once developed. We can 

 prevent or check an outbreak with good serum properly ad- 

 ministered. 



There are two methods in practical use today for adminis- 

 tering the serum: First, the "simple serum" treatment. This 

 consists of giving only the anti-hog-cholera serum, and there is 

 no possible way of scattering the disease in using it. This can 

 be used on practically any age animal, giving better results, 

 however, on the older animals. It produces a passive immunity 

 which lasts from 60 to 90 days. This is a very good treatment 

 to use if one follows it up by cleaning up his yards, but unless he 

 does he had better repeat the treatment in about 60 days or 

 there is danger of a new outbreak. If you expect to get rid of 

 the disease, which should be every one's aim, this is the ideal
