    Snippet: We developed the scenario tree model to evaluate the efficacies of interventions for BVD control using the archived data of Nemuro, Hokkaido where the cattle infected with BVDV have been reduced by the independent eradication program. The model output indicated that the adoption of mass vaccination apparently decreased the number of missed BVD cattle, although it did not increase the number of detected BVD cattle.

    Document: We developed the scenario tree model to evaluate the efficacies of interventions for BVD control using the archived data of Nemuro, Hokkaido where the cattle infected with BVDV have been reduced by the independent eradication program. The model output indicated that the adoption of mass vaccination apparently decreased the number of missed BVD cattle, although it did not increase the number of detected BVD cattle. Under implementation of mass vaccination, the efficacy of an individual test with lower coverage was equal to that of the herd screening test using bulk tank milk. Moreover, the switch from the individual to herd screening test under a situation of very low BVDV prevalence should be critical to achieve BVD eradication more efficiently. The scenario tree model developed was useful to simulate the BVD eradication program in the endemic area.
