摘要

Selection for heavy muscling has been shown to promote the expression of type IIB muscle fibres (fast, glycolytic) in a number of species including pigs and cattle (Wegner et al. 2000). Type IIB fibres have greater glycolytic rates than in type I (slow, oxidative) or IIA (fast, oxidative) fibres. Therefore, the recent focus on selection for muscling in Australian meat sheep breeds could potentially impact on rate of pH decline (pHk) or ultimate pH (pHu) in post-mortem (PM) muscle.
