Abstract
Dry-ageing of sheepmeat is a novel application, and there is an opportunity to optimise process yields through the selection of appropriate animals and or carcases for dry-ageing. The effects of carcase characteristics and sheep breeding values (post-weaning and yearling; fat depth, muscling and weight) on yields from wet- and dry-aged sheepmeat were investigated. Bone-in leg and loin primals from 96 multipurpose merino cull ewe carcasses were wet- or dry-aged for 14, 28, 42 or 56 days. The yield components’ primal moisture loss %, trim yield %, saleable meat yield % and retail cut yield % were determined. For loin and leg, dry ageing increased primal moisture loss but decreased saleable mea..
