| Research Abstract |
In order to estimate the spread manner of bovine viral diarrhea virus (BVDV) in and among the dairy herd, epidemiological and immunological analyzes were done for the BVDV detected and free herd discriminated by the bulk tank milk tests. Although the correlation between the geographical place of farm and outbreak of BVDV was recognized, prevalent viruses were not common based on the genetical analysis of the detected virus gene. On the immunological analyzes, BVDV might prefer to localize in ovary fluid in the infected cattle. Moreover, it was strongly suspected that BVDV might bias the immune status of infected cattle for the easy transmission of virus in uterus.
