Abstract
The Oregon biosecurity education and demonstration program using Bovine Viral Diarrhea virus, Persistently Infected (BVD PI) cattle screening as a model to minimize risk of infectious disease and initiate BVD control was introduced to Oregon cattle producers in October 2008. To date we have spoken to cattle producers across the state of Oregon at ten different locations. The program has been highlighted in the Oregon Beef Producer Magazine and various other periodicals. We have reached out to our clientele via written, web, and spoken education. To date 900 producers have either attended a seminar or a trade show in which Oregon Biosecurity/BVD Control Program was highlighted. More than 300 producers have actively collected our written research and educational materials and 9,000 people have been exposed to the program via popular media. To date 11,096 hd of cattle have been enrolled in the OSU Biosecurity/BVD program representing 41 ranches located in 18 counties (50% of Oregon counties). Of which, 9,611 animals have completed BVD PI screening from 38 ranches. These preliminary results indicate the prevalence of BVD PI in Oregon is 0.06% of all cattle. Data suggests the prevalence of BVD PI among all cattle is lower than the reported national prevalence (0.13-2.0%). However, data also indicates there are more ranches (10.5%) in Oregon that have at least one animal test positive for BVD PI than the national rate (4%). The preliminary data does not adequately represent the geographical distribution of the cattle population or ranches in Oregon and therefore further BVD PI screening needs to be conducted.
