78 Seventeenth Annual Report of the 



This entire chapter of the law is day by day gaining favor 

 with the stockmen and others who have had sufficient experience 

 with tuberculosis to know the necessity of guarding against the 

 traffic of tuberculous cattle from one herd to another, and the 

 necessity of permanently marking tuberculous animals so that 

 those who have to deal with them may be able to identify them 

 as tuberculous. Thereby it becomes possible to keep the affected 

 from the well and so assists in building up new and clean herds 

 without the immediate annihilation of all affected ones. The 

 honest use of tuberculin is a thing of equal necessity. 



Bovine tuberculosis is more or less prevalent in our state; 

 more herds and a larger percentage of animals in herds are 

 affected than some are willing to believe. Consequently, there 

 seems to be a feeling in the public mind that it is a disgrace to 

 have a tuberculous animal. If, however, all facts were known, 

 there are very few herds entirely free from infection unless they 

 have been made so by a religious application of the tuberculin 

 test, the segregation of the diseased and the guarding against 

 infection of young slock. If every stock owner could be induced 

 to make a division of his herd and begin raising non-tuberculous 

 offspring in a careful, conscientious way, with the aid that the 

 state is giving in education and money, our progress would be 

 more and more satisfactory. 



It is pleasing to be able to state that the segregation or Bang 

 method has been adopted by many dairymen and farmers 

 throughout the slate. Many of the stockmen who are ever in 

 I lie front speak of the system as having great merit. Some 

 utilize the product of the reacting animals that show no physical 

 symptoms of the disease by pasteurizing it and feeding it to 

 calves that are to be raised or fattened; others, equipping their 

 dairies with a pasteurizing apparatus, place their surplus milk 

 ;ind cream on the market. Following is a summary of the work 

 done toward the control of tuberculosis: 



During the last fiscal year, 9,430 cattle have been examined 

 for tuberculosis as against 5,703 of last year. 



Two thousand three hundred and forty cattle have been con- 

 demned as against 1,229 of last year.
