Skillful diagnosis and the administration of potent and dangerous drugs require training and experience. County extension agents can render valuable service in the following manner: (1) Advise farmers and stockmen in regard to measures necessary to prevent the introduction of infection and to restrict the spread of disease; (2) report centers of infection to the proper authorities; (3) cooperate with organizations, practicing veterinarians, and State and Federal officials in dealing with the suppression of disease outbreaks. HORSES, MULES, AND ASSES Transmissible Diseases Most Frequently Observed Anthrax (Charbon)-Description.-Severe and usually fatal contagious disease to which practically all animals, including man, are susceptible. Most prevalent in low, moist lands during warm weather. Symptoms develop rapidly and consist of great depressions, chills, muscular weakness, high temperature, fast breathing, and rapid heart action. After death decomposition is rapid, and body openings exude a bloody foam. Control.-Medicinal treatment is not satisfactory, although the use of serum often gives good results. Prevention consists in keeping animals from known infected areas, the destruction of animals dead from the disease by complete burning, and by the use of immunizing vaccine. Never skin or cut open the body of an animal dead from the disease. Burn all body discharges, and disinfect contaminated premises. Report outbreaks to livestock sanitary officials. asses. Distemper (Strangles)--Description. Infectious disease most frequently observed in immature horses, mules, and One attack usually gives permanent immunity. Begins with a fever and most often associated with an abscess formation under the jaw. Coughing and abundant nasal discharge are common symptoms. Most cases recover if proper hygienic treatment is given; however, such sequela as bronchitis and pneumonia may complicate conditions. Control.-Separate healthy from infected animals, and disinfect stables where disease has occurred. Ordinary cases seldom require more than good care, such as protection against cold, giving of nourishing feed, and a mild laxative. Avoid infected premises such as public stables. A vaccine with curative and protective power is now procurable for the treatment of ånd immunization against this disease. Infectious Abortion-Description.-Expulsion of a dead fetus or of one so immature that life is impossible is termed abortion. A large majority of abortions is caused by infection, This form is highly contagious and occaU. S. D. A.-10-1-26 |
