Malignant Tumors 241 



When amputating the penis of a bull (or ram or boar) it 

 must be recalled that these animals are always affected with 

 the granular venereal disease, which retards healing and 

 aggravates the wound. Prior to amputation it is therefore 

 advisable to disinfect the glans, prepuce, and sheath by- 

 douching the parts daily for five to eight days with a 0.25 

 to 0.5 per cent. Lugol's solution, or other safe antiseptic. 

 After the penis has been amputated, it is desirable to con- 

 tinue the douching until the healing is complete. 



The bull should be kept apart from cows in estrum, and 

 otherwise handled in a manner to obviate sexual excitement, 

 because erection inevitably aggravates any penial disease. 

 It is bad policy generally to cause the bull to become sexu- 

 ally excited in order to have him protrude the penis for 

 visual examination in case of disease. It is better, and far 

 more satisfactory from every standpoint, to cast the bull 

 and expose the penis by eliminating the S-curve, as de- 

 scribed in Chapter II. 



If the ordinary douching of the sheath and prepuce fails 

 to hold in check the infection and inflammation in the stump, 

 the animal should be cast, the penial stump exposed, and 

 the inflamed' areas pencilled over with silver nitrate or 

 dressed with a strong solution of the same. It should be 

 remembered that the conditions are inimical to prompt 

 healing and that it is far better to hasten the healing pro- 

 cess to the maximum by giving concentrated attention at 

 the beginning, thus obviating the necessity for prolonged 

 handling which will in the end greatly exceed the total care 

 required if minute details are faithfully followed at first. 



Hendryckx 1 states that in the course of malignant disease 

 of the testicle the organ may undergo necrosis and open 

 upon the exterior of the scrotum and the new-growth as- 

 sume the clinical characters of external cancer. > . 



When malignant neoplasm of the testicle is diagnosed or 

 seriously feared, the gland should promptly be removed. A
