When any owner of cattle in the State places the owner’s herd of cattle under state-federal supervision for the eradication of Bang’s disease, and signs the federal agreements for the testing of the owner’s herd, the blood samples from the owner’s cattle shall be taken by a veterinarian designated by the Department of Agriculture and tested in the laboratory of the Department or a laboratory officially designated by the Department, by the agglutination test. All animals which show a positive reaction to this test shall be identified by a “reactor” ear tag and brand, and shall be slaughtered, under federal or state supervision. Animals showing a suspicious reaction to the agglutination test shall be held for 60 days and retested.
