Treatment, Prevention. 759 



Prevention. For preventing the spread of the disease it 

 is advisable to segregate the healthy animals from the affected 

 ones, to disinfect repeatedly and thoroughly the infected stables, 

 and especially the stalls, as well as the draining gutters, and 

 if possible to prevent the affected cows and bulls from copula- 

 tion during the duration of the disease. This measure can be 

 carried out in practice only at considerable expense on account 

 of the resulting falling off in the number of calves. In bulls 

 which are exposed to the danger of infection the brush of hair 

 at the opening of the sheath should be cut short, and the sheath 

 should be irrigated after every copulation with a mild disin- 

 fecting solution. Finally, in order to prevent the introduction 

 of the disease, newly bought female animals should be care- 

 fully examined for the presence of the disease.
