Voluntary and compulsory eradication of bovine viral diarrhoea virus in Lower Austria
Résumé
A voluntary BVDV eradication program without vaccination was introduced in Austria in 1997, according to the Swedish model employing herd-level antibody tests. Since this time, identified persistently infected (PI) animals have to be slaughtered. In order to protect non-infected herds, the major routes of introduction of BVDV infection into a herd, such as communal grazing and livestock trade, have to be controlled.
