Abstract
Porcine reproductive and respiratory syndrome virus (PRRSv) can have a significant, economic impact on swine herds due to reproductive failure, preweaning mortality and reduced, performance in growing pigs. Control at the farm level is pursued through different management, procedures (e.g. pig flow, gilt acclimation, vaccination). PRRSv is commonly eliminated from sow, herds by a procedure called herd closure whereby the herd is closed to new introductions for a period, of time during which resident virus dies out. However, despite thorough application of biosecurity, procedures, many herds become re-infected from virus that is present in the area. Consequently, some, producers and veterinarians are considering a voluntary regional program to involve all herds present, within an area. Such a program was initiated in Stevens County in west central Minnesota in 2004., PRRSv has been eliminated from most sites within the region and the area involved has expanded to, include adjacent counties. The program has been relatively successful and reflects local leadership, a, cooperative spirit, and a will to eliminate virus from the region.
