150 DISEASES OF SWINE

 production of the disease. AH possible precautions 

 against infection through the food supply should 

 be taken. Feeding hogs on the ofifal from the 

 slaughter-house and the carcasses of other animals 

 is especially harmful, and should not be practiced. 

 The feeding of skim milk and slops from a dairy,

 be established, and all danger of contracting 

 tuberculosis from this source, at least, is avoided.

 it as do horses, cattle, and dogs, but wherever
