Data from 2017 official animal movements, biosecurity questionnaires, scientific literature, and expert opinion from field veterinarians were taken into consideration for model input parameters. Purchasing or introducing cattle, rearing replacement heifers offsite, showing cattle at competitions, sharing transport vehicles with other herds, and transporting cattle in vehicles that have not been cleaned and disinfected were considered in the model. The annual probability of introducing BVDV or BoHV-1 through infected animals was very heterogeneous between farms. The median likelihoods of BVDV and BoHV-1introduction were 12 and 9%, respectively. Farms that purchased cattle from within their region (i.e., local movements) and shared transport with other farms had a higher probability for BVDV and BoHV-1 introduction. This model can be a useful tool to support decision-making on biosecurity measures that should be prioritized to reduce the probability of introduction of these 2 diseases in dairy herds PB Elsevier SN 0022-0302 YR 2020 FD 2020 LK http://hdl.handle.net/10347/24253 UL http://hdl.handle.net/10347/24253 LA eng NO Journal of Dairy Science, Volume 103, Issue 7, July 2020, Pages 6454-6472 NO This work was supported by a Grant from the Ministerio de Ciencia e Innovación of Spain (AGL2016-77269-C2-1-R and AGL2016-77269-C2-2-R).
