208 SWINE PRACTICE 



eroded and the typical actinomycotic pus discharged. Actinomycotic 

 mammitis is characterized by the presence of the tumefaction, which 

 may be round and have a smooth surface or it may be lobulated. 

 These tumefactions vary in size from that of a small marble to 

 masses larger than a baseball. 



Ablation of the entire tumor is the most rational and successful 

 manner of combating and relieving this trouble. 



TUBERCULOUS MAMMITIS 



Tuberculous mammitis is relatively common in swine. The infec- 

 tion of the mammae may be due to a diseased condition elsewhere 

 in the body or it may be introduced through wounds from the out- 

 side. 



The lesions are the same as other tuberculous lesions. 



Treatment. — If the infection is localized in the mammjE the dis- 

 ease may be successfully treated by operation, but the safest and 

 most sanitarj' plan is destruction of the animal and cremation of 

 the carcass, thereby diminishing the possibility of spreading the 

 infection. 



TUMORS 



Mammary tumors are rare in swine, though an occasional papilloma 

 may be observed upon the teat. Rarely do adenomas occur in the 

 mammae of swine, although a few cases have been reported.
