Abstract
Several diff erent strategies for control and eradication of Classical Swine Fever (CSF) were compared using a Monte Carlo method-based simulationmodel. Th e control strategy analyzed in this paper, in addition to other CSF control measures, includes application of biosecurity measures on pigfarms and rural backyard holdings. Elements of the control strategy are based on applicable regulations and include the simulation of detection ofthe disease, setting up the protected and surveillance zones, standstill of pig movements and restricted movement of animals, vehicles, equipment, and people with strong control measures in protection and surveillance zones, euthanasia of susceptible pigs, protective vaccination of pigs, compensation etc. During the simulation, diff erent output parameters were compared such as: duration of epizootic of a disease, number of aff ected holdings and animals, direct costs such as those for dead or culled animals, costs of surveillance, disposal of infectious materials, cleaning and disinfection.Depopulation of aff ected animals with early diagnostics and vaccination in protection and surveillance zone proved to be the most eff ective measures to stop spreading and eradication of the disease. However, during the simulation, systematic implementation of biosecurity measures in all pig production clusters demonstrated to be appropriate strategy for sustainable control of CSF and setting up a stable epizootiological situation.
Highlights
Classical swine fever (CSF) is highly contagious disease of viral etiology affecting domestic and wild pigs
Scenarios 2-4 dealt with potential modifications of current control strategies and the assessment of their effects when applied in conditions of Classical Swine Fever (CSF) control using preventive vaccination policy
The simulation indicated that the area for preventive euthanasia of pigs should be set to a radius of max 50m around extensive rural holdings and family farms type A and B, and 500m around commercial pig farms
Summary
Classical swine fever (CSF) is highly contagious disease of viral etiology affecting domestic and wild pigs. CSF is the most severe threat to national pig industry in all countries. The disease is spread worldwide and is reported at all continents. Models and simulation of CSF epizootics enables assessment of disease dynamics as well as economic effects of implemented control measures. The objective of this article is to analyse potential control strategies for eradication of CSF in the Republic of Serbia based predominantly on improvement of biosecurity measures on a typical rural holdings and gradual upgrading of rural holdings to higher farm categories
