摘　　要：本研究对北京地区中小奶牛场及养殖小区进行了牛传染性鼻气管炎(IBR)、牛病毒性腹泻病(BVD)的风险评估。结果表明,参试牛场及小区的后备牛IBR血清阳性率达50.52%,BVD血清抗体阳性率达70.98%;从牛场水平看,24个牛场中IBR抗体场间阳性率达到50%(12/24),BVD抗体场间阳性率达到87.50%(21/24),IBR高风险牛场9个,BVD高风险牛场12个,双高风险牛场7个。此次评估结果表明,北京地区IBR流行情况较为严重,应考虑疫苗免疫;参试的大部分牛场有BVDV的急性感染史或接触史,高风险牛场应启动BVDV清除计划。The epidemiology of the infectious bovine rhinotracheitis （IBR） and bovine viral diarrhea （BVD） were assessed in the medium and small dairy herds and the farming community in Beijing. The percent of IBR antibody-positive heifers was 50.52%, and the result was 70.98% for BVDV. At the herds level, the antibody positive rate reached 50% （12/24） for IBR and 87.50% （21/24） for BVD. IBR high-risk herds were 9, BVD high-risk herds were 12, seven herds were combination risk of IBR and BVDV. The serological investigation and analysis showed that IBR prevalence is relatively serious in Beijing, and vaccine should be considered; Most of herds had BVDV history or contact with acute infection, high-risk herds need to start BVDV eradication program.
