A study was carried out in 24 buffaloes affected with Bovine Respiratory Disease (BRD) Complex, which were diagnosed based on the history and clinical findings of inappetance to anorexia, fever, nasal discharge, coughing, dyspnoea and abnormal lung sounds on auscultation of thoracic area. The affected animals were randomly categorized in three groups for treatment to evaluate the therapeutic efficacy of ceftiofur, levofloxacin and moxifloxacin. Based on remission of clinical signs and symptoms ceftiofur was found to be most effective antibiotic for treatment of BRD complex in buffaloes.
