Show Decrease in "TB" of Cattle Shown Efforts Made to Cut Down Losses Due to Malady Effective. (Prepared by the United Stntes Derrirtment of ARric'llture.) WNU Service. The success of the nation-wide campaign to eradicate bovine tuberculosis tubercu-losis has been due largely to the determination de-termination on the part of the public not to tolerate the presence of such a dangerous live stock malady. This is the opinion expressed by Dr. A. E. Wight, in charge of tuberculosis eradication eradi-cation for the United States Department Depart-ment of Agriculture, at a recent annual an-nual meeting of the United States Live Stock Sanitary association, at Chicago. Referring to the results obtained by the campaign, Doctor Wight gave the following comparison: In the 15-year 15-year period ended in 190S, 400,000 tuberculin tests were applied which disclosed an infection of 10 per cent. In the year 1031 alone more than 13,-000,000 13,-000,000 tuberculin tests showed only 1.5 per cent infection. This was at the rate of more than a million tests a month and is an indication of the vast effort being put forth to conquer tuberculosis among cattle. "Tuberculosis eradication work under un-der the area plan continues to be a satisfactory, and practical method of ( exterminating the disease," Doctor Wight said. "Since the first of November, No-vember, 1930, 216 counties have been added to the modified accredited area where the degree of Infection has been found to exist to not more than one-half one-half of 1 per cent. This makes a total of 1,271 counties, or nearly 42 per cent of the total number of counties coun-ties in the United States, in which bovine bo-vine tuberculosis has been practically eradicated." Among other subjects discussed by Doctor Wight were tuberculosis-free stock yards and the interstate shipment ship-ment of cattle. These problems, he said, will be greatly simplified when more of the cattle-producing counties can be placed in the modified accredited accred-ited area. |
