National Scrapie PlanThe National Scrapie Plan (NSP) is a long-term plan which consists of anumber of genotyping schemes and initiatives aimed at increasing thegenetic resistance to scrapie in the national sheep flock.The NSP Genotypes Table on the next page shows the 15 known genotypeswhich occur in sheep and their relative resistance or susceptibility to scrapie.The prevalence and frequency of each genotype differs between breeds. Thistable is subject to continuous scientific review.13

It is hoped that as many eligiblebreeders as possible will want to play their part in the NSP.14
