Tuberculosis of the Female Genitalia 355 



The greatest weapon for the control of the danger lies in 

 the more general inspection of the genitalia of cattle, as a 

 safeguard against sterility and abortion. It is becoming 

 more and more apparent that a careful physical examina- 

 tion of the genitalia of cows, prior to breeding, is a wise 

 precaution of distinct scientific and economic importance, 

 and that the breeder should take far greater care in the sex 

 hygiene of the bull. If penial injuries and infections are to 

 be averted, having first ascertained that the genital organs 

 of the cow are healthy, the external genitalia of both cow 

 and bull should be carefully washed before permitting copu- 

 lation. It is highly important, in the prevention of penial 

 lesions, which may serve as infection avenues, that the 

 crusts of pus in the vulvar tuft of hairs of the cow be re- 

 moved by washing. Otherwise, these crusts of pus may be 

 caught and forced into the vulvar opening, to abrade the 

 penial mucosa. After copulation, the penis, prepuce, and 

 sheath of the bull should again be carefully and efficiently 

 douched. These precautions go hand in hand with those 

 designed to control sterility and abortion.
