Extract

Although a considerable amount of research is being carried out in molecular genetics, few results have as yet found practical application in livestock breeding. In a previous study, quantitative trait loci (QTL) for growth and carcass traits were identified in commercial Texel and Suffolk sheep in the UK (Walling et al., 2004) and in Charollais sheep (McRae et al 2005). QTL were identified for muscle depth on chromosome 18 for Texel Sheep and Chromosome 1 for Suffolk and Charollais sheep. The current study aims to verify that QTLs for muscle depth found in commercial sheep are segregating in independent populations, and implement the technology required for the integration of genetic markers into commercial sheep breeding programmes.
