Abstract

The Australian lamb industry uses Australian Sheep Breeding Values for reduced postweaning subcutaneous fat depth (PFAT) to select for leanness and increased lean meat yield. Selection for reduced PFAT results in increased loin muscle weight (Gardner et al 2010) potentially leading to lower oxidative capacity in muscle (Greenwood et al 2006). Isocitrate dehydrogenase activity (ICDH) is an accepted indicator of aerobic metabolism, and therefore we hypothesise that selection for reduced PFAT results in a decrease in ICDH levels.
