  • Major swine viral diseases: an Asian perspective after

    2009-2-1 · A spreadsheet model using Monte Carlo simulation was designed to evaluate the introduction of bovine viral diarrhea virus (BVDV) to cow–calf farms and the effect of different testing strategies. Risks were modeled to include imports to the cow–calf herd and stocker calves imported to adjacent pastures. The number of persistently infected (PI) ...

  • A stochastic model to assess the risk of introduction

    For understanding the factors affecting bovine viral diarrhea virus (BVDV) transmission, this study investigated the distribution of BVDV and the epidemiological features of persistently infected (PI) cattle in Ibaraki Prefecture of Japan, and identified farm-level risk factors associated with BVDV infection, with a focus on within-farm transmission and PI animal detection.
