feeding of farm animals and numerous animal diseases, among 

 wliicli may be mentioned: milk fever of cows; contagious and 

 sporadic abortion ; hog cholera : intestinal parasites of horses, 

 cattle, sheep and swine; tuberculin testing, etc. 



An especially large number of letters have been received 

 asking for information concerning the source, symptoms and 

 treatment of hog cholera. From the increase of inquiries over 

 previous years and the press reports, it appears that this disease 

 has been much more prevalent in the State during the past 

 twelve months than ever before. 



If the stockmen could only realize that the great majority of 

 the outbreaks of hog cholera have their origin in swill contain- 

 ing scraps of uncooked western pork from centers of infection, 

 and that thorough cooking will destroy the infection, many of 

 the troublesome outbreaks could be easily prevented, and the 

 swill from hotels and boarding houses into which such contami- 

 nated pork scraps are almost certain to find their way could be 

 fed with safety and profit in the rearing and growing of hogs in 

 Massachusetts.
