Research Program

Given the diversity of situations encountered (animal flow, density, uncertainty about the status of animals), ex ante evaluation of the expected efficacy of different control strategies is a major expectation of professionals. Generally speaking, the work carried out by the MODEC team aims to describe the methods of intra- and inter-herd spread of the BVD virus in order to deduce the most appropriate control measures.

The work carried out over the period 2006-2010 involved

• Simplification of existing intra-flock propagation patterns 
• The spread of the BVD virus within a controlled metapopulation 
• The evaluation of different infection control strategies in a herd 
• The impact on the regional prevalence of BVD in cattle depending on whether the proposed control plan is mandatory or voluntary 
• The evaluation of the economic impact of new cases in livestock farming 

Work in progress and prospects concern

• Modelling of the inter-herd diffusion of Map, based in particular on the analysis of animal movement networks
• The evaluation by modelling of the ex ante effectiveness of different control strategies, based in particular on the management of cattle flows according to the status of the herd to which they belong.
• The cost-benefit assessment of different control strategies, based in particular on the existence of incentive measures.
