Leucosis bovina enzoótica.

Abstract

In the farm “Paradise” at Tame municipality (Arauca) a bovine male, Gyr Breed (Dairy cattle), 4 years of age, with clinical history of diarrhoea, decay and sialorrhea, was treated with Hemopar ® B12 (Diminacene diaceturato + Oxytetracycline + Vit B12) and responded satisfactorily to the treatment. However, because of farm history of sanitary issues, a blood sample was taken for hematology and for detection of antibodies against bovine viral diarrhoea (BVD), Infectious bovine rhinotracheitis (IBR), Bovine Leptospirosis, and Enzootic Bovine Leukosis (LBE). Results were positive for IBR, Bovine Leptospirosis and LBE. Because LBE has neither treatment nor vaccine available, it was advice to the owner to sacrifice treatment to prevent spread of the disease. (Simultaneously, the same serological tests were performed to two cows that were in production), having positive serologies for IBR and leptospirosis. It was advice to begin a representative sampling of the population for to know the sanitary status of the farm, and to do a vaccination plan.
