and is a disease affecting the heart and lungs. Little pigs often 

 times get too fat dae to lack of exercise and too much feed from 

 the mother. Their sides throb like the sides of a panting horse. 

 The disease runs its course in a week or so, the pig wasting away 

 in the meantime and finally dies. I know of no cure. This 

 trouble may be avoided by forcing the pigs to exercise and by 

 cutting down on the feed of the mother. 



Cholera causes 90 per cent, of the losses in swine. It is 

 erratic, some years are noted for the absence of it, and then again 

 particular years are bad. There are too frequent outbreaks for 

 the good of the business. 



There is no known cure for cholera — as a rule it is fatal, 

 although there is the chronic form where a ho2 will linger along. 



Here again preventative measures should be taken to keep 

 the herd free. Particular care should be taken that new hogs 

 coming into the herd should be quarantined for at least two 

 weeks. 



Cleanliness of yards and houses is another important factor. 

 A little air-slaked lime sprinkled on the floors and in the yards is 

 an excellent thing. 



There is some danger also in the feeding of garbage, of 

 earning the disease — particularly through pieces of raw pork 

 which may have gotten into the garbage. 



The serum treatment for the prevention of hog cholera has 

 proved efficient in the majority of cases where tried. The double 

 treatment is more or less of an experiment as yet, and its use is 

 questioned in herds where cholera does not exist. So many out- 

 breaks of cholera have been started through the use of the 

 double treatment as to make many skeptical of its use. Much of 

 the loss through the double treatment has been due to the care- 

 lessness in handling the virus ; this virus carries the hog cholera 

 germs and produces hog cholera. Some states have limited its 

 use to skilled veterinarians only.
