Assessing the impact of changes to the National Scrapie plan - SE0238

Recent European legislation requires member states to implement a compulsory breeding programme for resistance to TSEs in sheep from April 2005. It is likely that it will be necessary to change the current, voluntary National Scrapie Plan (NSP) once participation becomes compulsory. Consequently, there is a need to assess the potential impact of the proposed changes to the NSP. The aim of this project is to use mathematical models to investigate the effect of both the current scheme and the new strategy (including several possible variants). In particular, for each strategy, the models will be used to assess: (i) changes in the genotype profile of the national flock over time; (ii) the impact of the change in the genotype profile on the level of scrapie in the national flock; and (iii) changes in the percentage of lambs entering the food chain carrying at least one ARR allele and of the ARQ/ARQ genotype.
