摘　　要：为了解承德地区规模化肉牛养殖场中犊牛、青年牛、后备牛及成年牛等不同阶段肉牛的传染性鼻气管炎(IBR)的流行情况,该研究于2023年1月—2024年3月期间采集承德地区规模化肉牛养殖场中疑似患IBR不同阶段肉牛病料组织(鼻拭子、咽拭子和血液)样本共计1 127份,采用PCR检测试剂盒分别对采集的病料组织样本进行IBR病毒检测,分析其感染情况。结果显示,从采集的1 127份不同阶段肉牛病料组织样本中IBR总阳性率为14.6%,犊牛、青年牛、后备牛和成年牛的IBR阳性率分别为23.7%、17.8%、8.3%和7.1%,其中犊牛和青年牛的IBR阳性率高于后备牛和成年牛,不同阶段牛的IBR主要分布于鼻拭子和咽拭子样品中。为该地区规模化肉牛养殖场中不同阶段肉牛的IBR流行病学调查与综合防控提供参考依据。In order to understand the prevalence of infectious rhinotracheitis(IBR)in calves,young cattle,reserve cattle,and adult cattle at different stages of large-scale beef cattle farms in Chengde area,this study collected a total of 1127 suspected IBR samples(nasal swabs,throat swabs,and blood)from beef cattle at different stages of large-scale beef cattle farms in Chengde area from January 2023 to March 2024.PCR detection kits were used to detect IBR virus in the collected samples and analyze their infection status.The results showed that the total positive rate of IBR in 1127 beef cattle samples collected at different stages was 14.6%.The positive rates of IBR in calves,young cattle,reserve cattle,and adult cattle were 23.7%,17.8%,8.3%,and 7.1%,respectively.Among them,the positive rates of IBR in calves and young cattle were higher than those in reserve cattle and adult cattle.IBR in cattle at different stages was mainly distributed in nasal and pharyngeal swab samples.To provide reference for the epidemiological investigation and comprehensive prevention and control of IBR in beef cattle at different stages of large-scale beef cattle farms in the region.
