Extract

Quantitative trait loci (QTL) located on chromosome 2 in the region of the myostatin gene or polymorphisms in the myostatin gene have shown major effects on sheep carcass muscling (e.g. Clop et al., 2006). MyoMAXTM (MMQTL) is one such QTL/allele identified in Texel sheep, which increases carcass muscling and reduces carcass fatness (e.g. Laville et al., 2004; Johnson et al., 2005). The UK sheep industry may benefit from using MM-QTL to increase meat yield in lamb carcasses once its effects are verified in a genetic background typical of the stratified UK system.
