• Antibiotics should only be used to treat diseases with bacterial etiology or when such etiology is strongly indicated or suspected.
• Diagnosis of bacterial infections accompanied by sensitivity testing should precede treatment with antibiotics whenever possible.
• When treating bacterially induced diseases in production animals the ambition should always be to use pharmaceuticals with a narrow anti- biotic spectrum.
• When treating groups of animals an etiological diagnosis should be obtained and a treatment plan established.
• When high treatment rates or unorthodox use of antibiotics are discove- red the underlying reasons and/or predisposing factors should be investi- gated and corrected by means of preventive measures whenever possible.
