A cross-sectional study was carried out to identify risk factors for bovine viral diarrhea virus (BVDV) infection in 62 randomly selected dairy herds which were tested for BVD serum antibodies by using an indirect ELISA kit (IDEXX). Results from the chi-square test analysis were interpreted by analyzing by chi-square test. A sum of 500 sera samples were screened and 66 animals (13.20%) showed positive for BVDV antibody. Within herd, BVD seroprevalence was 12-65%. This study concluded that epidemiological risk factors like location, herd size, housing patterns like, tail to tail system, roofing pattern, distance between the manure pit and farm, and distance between farms were significantly associated with BVDV serological status (P < 0.05).
开展了一项横断面研究，以确定62个随机选取的奶牛场中牛病毒性腹泻病毒（BVDV）感染的风险因素，这些奶牛场使用间接ELISA试剂盒（IDEXX）检测了BVD血清抗体。通过卡方检验分析对卡方检验分析的结果进行了解释。共筛查了500份血清样本，66只动物（13.20%）的BVDV抗体呈阳性。在牛群中，BVD血清阳性率为12%-65%。本研究得出结论，地理位置、牛群规模、饲养模式（如尾对尾系统）、屋顶样式、粪坑与农场之间的距离以及农场之间的距离等流行病学风险因素与BVDV血清学状态显著相关（P < 0.05）。
