In view of the results of previous serological studies on the presence of SN antibodies to IBR virus in a minimum of ten per cent of the herd, the following procedure is suggested: (1) Vaccination of serologically negative herds in areas menaced by IBR virus. (2) Vaccination of IBR-negative groups of animals in herds in which serologically IBR-positive animals are present. When sampling shows that IBR-negative animals are present in every age group, vaccination of the entire herd should be contemplated. (3) Vaccination of all animals which are added to dairy herds including animals showing antibodies to IBR virus.
鉴于先前血清学研究结果表明，至少10%的畜群存在抗传染性牛鼻气管炎（IBR）病毒的抗体，建议采取以下措施：（1）对受IBR病毒威胁地区的血清学阴性畜群进行疫苗接种。（2）对存在血清学阳性IBR动物的畜群中的IBR阴性动物群体进行疫苗接种。当抽样显示每个年龄组都存在IBR阴性动物时，应考虑对整个畜群进行疫苗接种。（3）对添加到奶牛群中的所有动物进行疫苗接种，包括显示出抗IBR病毒抗体的动物。
