RAZOR-BACKS NOT CHOLERA-PROOF OR PROFITABLE 53 1 



sumed as those of the second generation, yet the data 

 presented clearly brings out the fact that they fell far 

 behind in rate of gain, and we may safely assume from 

 then- appearances that they were not nearly equal to the 

 pigs of the second generation, in ability either to con- 

 sume large quantities of food or to assimilate and store 

 the food nutriments in their body tissues." 



There should be no hesitation about recognizing the 

 qualities obtained through selection and breeding. In- 

 judicious work in this regard may, however, develop 

 bad traits as well as good ones, but the good breeder 

 will take care to eliminate these. More is to be lost 

 than gained by introducing strains of wild or Razor- 

 Back blood. The Razor-Back is at variance with any 

 desirable uniformity, and this applies to both fattening 

 qualities and form. In any case, where an attempt has 

 been made to introduce crosses of Razor-Back or any 

 other miscellaneous kind of swine, the results have been 

 in the end unsatisfactory.
