[Integrated disease control in dairy herds. A case study from the veterinarians' viewpoint].
Integrated control of bovine virus diarrhoea virus, bovine herpesvirus-1, Leptospira interrogans serovar hardjo subtype hardjobovis, Mycobacterium avium subsp. paratuberculosis, and Salmonella dublin in dairy herds may provide economic benefits superior to those obtained by sequential disease control, because, among other things, it allows optimization of voluntary culling. However, in practice there are no adequate instruments to establish priorities in voluntary culling. Therefore, in this study the priorities in decision-making for voluntary culling of infected cattle, as indicated by more than 300 cattle veterinarians, were analysed. Based on our results and supplementary considerations, the priorities for voluntary culling in the Netherlands can be ranked as: 1st. cull S. dublin carriers, 2nd. cull persistently infected BVDV carriers, 3rd. cull paratuberculosis faecal culture positive cattle and their last offspring, 4th. cull, in paratuberculosis infected herds, paratuberculosis ELISA positive cattle and their last offspring and cull, in low prevalence herds, BHV1 gE-positive cattle, and 5th. cull leptospirosis seropositive cattle. Since this ranking was based on one case study only, other priorities may prevail in other herds.
