ence to the fciliecp question are not on account of diseases but from 

 the ravages and extensive losses caused by dogs. Many more people 

 would keep sheep if their neighbors would keep fewer dogs, or those 

 they do liave at home wliere tliey belong. 



In sheep raising countries mange is an impoi'lant disease. It de- 

 preciates the value of each aninml atfected about one dollar. France 

 has practically 1,000,000 head of sheep atfected annually. It is said 

 that this disease virtually ruined the sheep industry in Iowa a few 

 years ago. 



Mange in cattle and horses is reported occasionally. It is easily 

 cured if taken in time. Old chronic cases are extremely obstinate. 

 All infected animals should be promptly isolated and treated with 

 the lime and sulphur wash or some other parasiticide. The disease 

 should be reported to the Board and suitable instruction will be 

 furnished for handling the affected animals and premises. 



The following table shows the extent of mange reported in horses 

 during the past two years:

HOG CHOLERA 



Hog Cholera is supposed to have made its appearance in America 

 in 1833 in the State of Ohio. It spread over the United States with 

 the development of shipping facilities. In 1913 it existed in 52 of 

 the 67 counties of Pennsylvania. This State is not heavily infested 

 as compared with the recognized hog raising states. The 1912 Fed- 

 eral census indicates that there were 1,130.000 hogs in this State at 

 that time. Our records for 1913 show that .02% of the hogs of the 

 State were exposed to infection wath a loss of .008%. 



For practical purposes the disease may be divided into two forms ; 

 the acute and chronic. In cases of the acute form the animal may 

 die without the owner noticing signs of illness. A post mortem ma,y 

 be held and no diseased organs or tissue found. These cases are 

 due to a very active form of infection. Death is due to septicemia. 



Animals affected with the chronic form present an entirely differ- 

 ent appearance. These cases are the most common and are easily 

 recognized. The animal has a high fever, ranging from 104.5 to 107
