Extract

In 2006, myostatin single nucleotide polymorphisms (SNPs) were identified on ovine chromosome 2 (OAR2), with two SNPs (g-2449C-G and g+6723G-A) having significantly higher frequency in hyper-muscled Belgian Texel than in control animals (Clop et al., 2006). In particular, the A allele of the g+6723G-A SNP was proposed to be a causative mutation for increased muscularity in Texel rams (Clop et al., 2006). We aimed to assess whether the above two SNPs were present in UK commercial Texel, Suffolk and Charollais breeds. Moreover, we performed association analysis of the SNP effects on phenotypes in an extended UK commercial population of Charollais sheep in order to further evaluate the SNP contribution to muscle and fat tissue composition, and to quantify and fully characterise the SNP effects in this breed.
