UDDER-PYOBACILLOSIS 85 



bring about a sclerosis and atrophy of the affected quarter. 

 In this way the progressive destruction of the udder is 

 prevented, healing is possible and at the same time the udder 

 becomes less susceptible to secondary infections. 



Deep point firing or cautery in a completely infected 

 quarter is indicated since the treatment greatly favors 

 sclerosis and contraction. 



If fluctuation is observed the abscess is opened with a 

 scalpel, the pus emptied, and the inside of the cavity thor- 

 oughly cauterized with a cautery iron. 



If a secondary milk-infection [parenchymatous mas- 

 titis] is complicated with it, this is additionally treated with 

 injections of boric acid solution and inflation with air. If 

 indications point toward death of the animal one may 

 possibly attempt to prevent it by extirpation of the diseased 

 half of the udder. 



In gangrene accompanied by high fever one can ampu- 

 tate the teat in order to induce free drainage of the secretion. 



In fever a febrifuge like camphor is indicated.
