146 MASTITIS OF THE COW 



it bears no abnormal odor. [The carcass should be care- 

 fully examined for lesions of septicaemia.] 



Chrome Udder-infections. — Their type plays a great 

 part in the judgment of meat. 



Chronic ndder-streptomycosis is always of a local char- 

 acter. The auriculo-ventricular valves of the heart may 

 show an endocarditis which might be the cause. Should 

 such really be the cause the meat may be used only after a 

 careful inspection and excision of metastatic lesions in the 

 meat. The heart, together with the organs containing 

 metastatic processes must be condemned. [Entire carcass 

 condemned.] 



If gangrene complicates the udder condition the meat 

 must be proved free from odor before it may be used. 

 [Entire carcass condemned.] 



Pyobacillosis and actinomycosis of the udder are usually 

 local conditions. They may be generalized, however, the gen- 

 eralization manifesting itself usually in the internal organs 

 only, as the lungs and liver. Condemnation of meat, fol- 

 lowing generalization of these conditions, is not, as a rule, 

 demanded. In complications of pyobacillosis with gan- 

 grene the odor of the meat determines the judgment. 

 [Entire carcass condemned.] 



Udder-tuberculosis^ as a rule, is an indication of gen- 

 eralized tuberculosis. Udder-tuberculosis is local and pri- 

 mary only when the lungs are free from the disease. 



In many cases of generalized tuberculosis only the in- 

 ternal organs are involved, leaving the muscles and bones 

 unaffected, so that all or part of the meat may safely be 

 used. [Entire carcass condemned.] According to the sta- 

 tistics of the abattoir at Malmo for the year 1905, edited 

 by Director A. M. Bergman, 155 cows were affected with 

 udder-tuberculosis of which, in 29 cases, or 19 per cent., the 

 tuberculosis was of slight extent, so that only single parts 

 had to be condemned.
