The prevalence of serum neutralizing antibodies to infectious bovine rhinotracheitis virus in 1152 serum samples from adult cattle in 114 dairy and beef herds in different regions of Scotland was 12%. In the Grampian region, the number of seropositive cattle in the self-contained herds was significantly less (P less than 0.01) than in the "other" herds. Holstein cattle had been introduced into five of these "other" herds, and significantly more (P less than 0.01) of the samples from these five herds were seropositive compared with the samples from the rest of the "other" herds in the same region into which recently purchased cattle had been introduced. The introduction of Holstein cattle was also a major factor in the association between the prevalence of antibodies and herd size in the Grampian region. The prevalence of serum neutralizing antibodies to infectious bovine rhinotracheitis virus was significantly greater (P less than 0.001) in this survey than in those previously undertaken in the United Kingdom.
在苏格兰不同地区114个奶牛和肉牛群的1152份成年牛血清样本中，牛传染性鼻气管炎病毒血清中和抗体的流行率为12%。在格兰扁地区，封闭式牛群中血清阳性牛的数量显著少于（P<0.01）“其他”牛群。这些“其他”牛群中有五个引入了荷斯坦牛，与同一地区引入了近期购买牛的其他“其他”牛群的样本相比，这五个牛群的样本血清阳性率显著更高（P<0.01）。在格兰扁地区，引入荷斯坦牛也是抗体流行率与牛群规模之间关联的一个主要因素。在本次调查中，牛传染性鼻气管炎病毒血清中和抗体的流行率显著高于（P<0.001）此前在英国进行的调查。
