SWINE MANAGEMENT.

In addition to cleanliness close attention should be given to the 

 feed, so that nothing may be fed that will convey the germs of disease, 

 especially tuberculosis, to the herd. If the hogs are fed milk in any 

 form obtained from cows kept upon the same farm, the cows should 

 be subjected to the tuberculin testo If they run with the dairy 

 cattle of the farm a tuberculin test of all the cattle is none the less 

 desirable. Animals dead from any disease should not be fed to the 

 hogs until the meat has been made safe by cooking. Skim milk or 

 refuse from a public creamery should not be fed to hogs until it has 

 been thoroughly sterihzed. 



Feeding and drinking places should be clean and the water supply 

 purCo Unless the origin is known to be uncontaminated and there 

 has been no possibility of infection during its course, hogs should not 

 be allowed access to any stream. Wallows should be drained out 

 and kept filled up as much as possible. At least once a month the 

 quarters should be disinfected with aii^-slaked lime or a 5 per cent 

 solution of crude carbolic acid. These precautions will be found 

 valuable aids in the destruction of the various animal parasites, as 

 well as a protection from some more serious troubles. 



DANGER IN INBREEDING AND IN STRAIGHT CORN DIET. 



While inbreeding is the surest and quickest means to fix type, it 

 should be resorted to with the greatest care. The value of the 

 system is that it enables the breeder to intensify desirable character-
