Extract

Gastrointestinal nematodes cause major losses to the UK sheep industry. As anthelmintic resistance is becoming a widespread problem alternative control methods are now sought. Breeding for improved parasite resistance is a possible control method (Woolaston and Windon, 2001). As genetic markers are now widely available there is considerable potential for application to livestock breeding through quantitative trait loci (QTL) detection and subsequent marker-assisted selection schemes. Although much work is underway, there are few published studies that identify QTL associated with parasite resistance. Therefore this study aims to identify QTL associated with parasitic nematode infection in a population of Scottish Blackface lambs using faecal egg count and Immunoglobulin A activity.
