INFECTIOUS DISEASES I29 



In no place on the farm are disinfectants so 

 necessary, as around the hog house and yards. 

 Whitewash and Hme should be used around the 

 hog houses at least once a year. An occasional 

 spraying of the feeding floors, pens, etc., with a 

 disinfectant will help in keeping away undesirable 

 germs. The tar disinfectants are the most con- 

 venient and useful for this purpose, and should be 

 used in from two to four per cent, solutions. 



Pastures and lots can be kept in a better sani- 

 tary condition, if the hogs are taken out for a few 

 months each year. The unused lots can be put to 

 a good use and cleaned up, by plowing and sowing 

 them to some forage crop. 



All possible precautions against the food and 

 drinking water becoming, infected with germs 

 should be taken. The importance of clean water, 

 clean feed, and clean troughs and feeding floors 

 must be emphasized, as it is in the feed that the 

 germs usually enter the system. Muddy yards are 

 always undesirable, and when in use for a few 

 years, are apt to become filthy. For this reason 

 they should be well drained and all wallow holes 

 filled in. Pens and pastures through which the 

 drainage from swine enclosures higher up runs, 

 should not be used for hogs. 



An occasional spraying or dipping of the hogs 

 with a one or two per cent, water solution of a tar 

 disinfectant, can be considered a necessary part of 

 their care. Pigs should not be placed in crowded 

 quarters, and attention should be given their feed-
