DISEASES OF CATTLE. 



of Leipzig the figures are 3(;.4 for cattle and 2.17 for hogs. (Siedam- 

 gi-otzky.) Of 'JO.snO animals in Belgium tested with tuberculin in 

 ISDC, 48.88 per cent reacted. (Stiibbe.) Of 2r»,439 tested in Den- 

 mark from 1893 to 1^^9.5, -19.3 per cent reacted; and of 67,203 tested 

 from 189G to 1898, 32.8 per cent reacted. (Bang.) 



Figures available in the United States do not cover a sufficient area 

 of our territory to allow us to make a reliable estimate of the extent 

 of tuberculosis with milch cows. There is little doubt, however, but 

 that the disease has been increasing both with dairy cattle and hogs. 

 From a review by Eussell and Hastings, of the Wisconsin Agricul- 

 tural Experiment Station, of tests of cattle for tuberculosis which 

 have been made in the United States, the following summary is 

 presented :

Reports of tuberculin tests made on 400,000 cattle in the United 

 States during the years 1893 to 1908 by Federal, State, and other 

 officers with tuberculin prepared by the Bureau of Animal Industry 

 show 37,008 reactions, or 9.25 per cent. These were mostly dairy 

 cattle, and in some cases herds were suspected of being diseased. 



All cattle in the District of Columbia, numbering 1,701. were tested 

 with tuberculin in 19()9-10, and 18.87 per cent reacted. In 1909-11 

 herds in Maryland and Virginia supplying milk to the District of 

 Columbia were tested, with 19.03 and 15.38 per cent of reactions, 

 resi)ectively, among 4,501 cattle.
