Abstract：The purpose of the study was to investigate the efficacy and safety of tulathromycin injection in the treatment of naturally infected swine respiratory diseases,and to provide a reference for clinical rational drug use.In a large-scale pig farm with respiratory diseases,120 infected pigs were selected according to the standard and randomly divided into the two groups(with 60 pigs in each group).The experimental pigs of two groups were respectively injected with tulathromycin injection and control injection once,and the dose was 2.5 mg/kg.The experiment lasted for 11 days.The results showed that tulathromycin injection had a good effect on the experimental pigs with natural respiratory diseases,and the pathogenic bacteria such as Actinobacillus pleuropneumoniae,Pasteulosis multocida and Haemophilus parasuis colonized in the nasal cavity of the experimental pigs could be eliminated in time.Fever,dyspnea,depression,loss of appetite and other symptoms can be rapidly and continuously improved until eliminated.On the 11th day of the experiment,the cure rate of the experimental pigs exceeded 75％,the effective rate exceeded 95％,and no adverse reactions were observed.The study indicates that the tested tulathromycin injection is safe and effective in the treatment of swine respiratory diseases,and can be widely use in clinical practice.
