Bovine herpesvirus type 1 (BoHV-1) is the causative agent for infectious bovine rhinotracheitis and infectious pustular vulvovaginitis in cows or balanoposthitis in bulls. In this study, individual and bulk tank milk (BTM) samples from 5 Catalan dairy farms with different control strategies against BoHV-1 were analysed during the course of a year for milk quality parameters and glycoprotein E gE) antibodies. Detection of gE antibodies was carried out with ELISA techniques. Prevalence of BoHV-1 varied between farms, and was stable during the study in individual and BTM samples. Comparing the antibody results of samples with milk quality parameters, positive samples with higher levels of antibodies corresponded to lower lactose and to higher percentages of fat and somatic cells.
牛疱疹病毒1型（BoHV-1）是奶牛传染性鼻气管炎、传染性脓疱性外阴阴道炎或公牛龟头包皮炎的病原体。在本研究中，对来自5个加泰罗尼亚奶牛场的个体和批量储存牛奶（BTM）样本进行了为期一年的分析，这些奶牛场针对BoHV-1采取了不同的控制策略，分析项目包括牛奶质量参数和糖蛋白E（gE）抗体。采用酶联免疫吸附测定（ELISA）技术检测gE抗体。BoHV-1的流行率在不同农场之间有所差异，并且在研究期间个体和BTM样本中的流行率保持稳定。将样本的抗体结果与牛奶质量参数进行比较，抗体水平较高的阳性样本对应的乳糖含量较低，脂肪和体细胞百分比更高。
