The aim of this preliminary study was to determine the prevalence of Bovine Viral Diarrhea Virus (BVDV) and its association with reproductive problems in cattle in Timika, Southern Papua, Indonesia, an emerging area for beef production. Serum from 77 beef cattle was collected from four villages and tested, using both antibody and antigen ELISA kits for BVDV. Data of the villages of origin, age, breed, sex and the number of parities of the cattle were collected. The pregnancy status of the cattle was determined by rectal examination. Results showed that the prevalence of BVDV antibody in individual cattle in Timika was 11.7% (CI: 6.1 – 20.0%), while at the farm level the antibody prevalence was 18.4% (CI: 8.9 – 33.7%).). Seropositivity for BVDV increased with age (P=0.02), from 0% (CI: 0 – 37.2%) in less than two-years old to 28.6% (CI: 11.3 – 55.0%) in cattle older than eight years of age. BVDV antibody was 2.9 times more prevalent in non-pregnant cows than in antibody negative cows (CI: 1.02 - 8.14, P=0.04). BVD antigen was not detected in the present study. This study reported for the first time, evidence of infection with BVDV in cattle in Papua and indicated that BVDV infection may be associated with infertility.

这项初步研究的目的是确定牛南部新兴地区巴布亚蒂米卡的牛病毒性腹泻病毒（BVDV）的流行及其与牛繁殖问题的关系。从四个村庄收集了77头肉牛的血清，并使用针对BVDV的抗体和抗原ELISA试剂盒进行了测​​试。收集了村庄的起源，年龄，品种，性别和胎次数的数据。通过直肠检查确定牛的怀孕状态。结果显示，蒂米卡（Timika）个体牛中BVDV抗体的患病率为11.7％（CI：6.1 – 20.0％），而在农场一级，该抗体的患病率为18.4％（CI：8.9 – 33.7％）。BVDV的血清阳性率随年龄的增长而增加（P = 0.02），从不到两年的0％（CI：0 – 37.2％）增加到28.6％（CI：11.3 – 55）。0％）在八岁以上的牛中。BVDV抗体在非妊娠奶牛中的流行率是抗体阴性奶牛的2.9倍（CI：1.02-8.14，P = 0.04）。在本研究中未检测到BVD抗原。这项研究首次报道了巴布亚牛BVDV感染的证据，并指出BVDV感染可能与不育有关。
