APPENDIX. 



The following report on the prevention of bovine tuberculosis was 

 presented to the Massachusetts Veterinary Association, and after 

 thorough discussion and revision, it was finally adopted by the 

 association at a meeting held on November 28, 1894, 



Realizing the importance of preventing the extension and con- 

 tinuance of bovine tuberculosis among our dairy herds, the Massa- 

 chusetts Veterinary Association has prepared the following brochure 

 in the hope that it may assist in spreading information on the pre- 

 vention and eradication of this disease. 



In referring to tuberculosis the following questions are often 

 asked by stock owners : (1) How shall the occurrence of tubercu- 

 losis be prevented in a healthy herd, and (2) how shall tuberculosis 

 be eradicated from a herd that is already diseased? 



In considering these questions it should be borne in mind that 

 while it is a fact that, no matter how unhealthy the surroundings, 

 bovine tuberculosis cannot exist without the presence of the bacillus, 

 yet it is equally a fact that the germ requires a suitable soil for its 

 development, and that a favorable condition of the body for the 

 development of tuberculosis frequently results from hereditary pre- 

 disposition, unsanitary surroundings and the injudicious management 

 to which dairy cattle are so often subjected. It follows then that 

 anything that tends to undermine the health of the dairy stock 

 should be avoided and a continual effort made to strengthen and 

 build up the constitution of the dairy cow. 



The following recommendations are made to stock owners to 

 prevent the occurrence of tuberculosis in a healthy herd : 



1. As far as possible owners should raise their own stock and 

 endeavor to improve the constitution of the herd by breeding only 

 from animals that are strong constitutionally and known to be free 

 from any tuberculosis taint. 



2. When practicable all farmers should own a bull. They 

 should restrict its use to their own cows, and not allow it to come 

 in contact with other stock. 



3. Allow no strange animal to come in contact with the herd 

 without first making sure by tuberculin test (which is now recog-
