清瘟解毒口服液联合氟苯尼考治疗白羽肉鸡传染性支气管炎的疗效分析OA

This study aimed to evaluate the therapeutic effect of Qingwen Jiedu Oral Liquid combined with florfenicol on infectious bronchitis virus(IBV)infection in white-feathered broilers.3 broiler farms with similar rearing scales and management practices,confirmed to have IBV infection,were selected as experimental subjects.They were divided into a treatment group(Qingwen Jiedu Oral Liquid+florfenicol powder)and a control group(Shuanghuanglian Oral Liquid+florfenicol powder).Changes in the number of dead and culled birds,feed intake,and clinical symptoms were monitored and recorded for 3 days before treatment and 5 days after treatment.The results showed that in the clinical treatment of infectious bronchitis complicated,compared with the control group,the treatment group exhibited a 1.22-2.03 percentage point reduction in mortality and culling rate,with a relative risk reduction ranging from 46.92%to 63.44%.Both groups maintained relatively high feed intake rates,but the treatment group showed a faster feeding speed than the control group.After treatment,respiratory symptoms in the treatment group were significantly alleviated,the mental state of the birds improved markedly,and no new sick birds were observed.In contrast,the control group continued to show an increase in sick birds,with no significant reduction in mortality and culling.In conclusion,the combination of Qingwen Jiedu Oral Liquid and florfenicol demonstrates superior efficacy in reducing mortality and culling rates,promoting feed intake,and aiding mental recovery,showing its potential value for promotion and application in poultry production.
