The histochemical characteristics, physical attributes, chemical composition, and sensory profile of three muscles (longissimus thoracis et lumborum – LTL, rectus abdominis – RA, triceps brachii – TB) from Fleckvieh (N = 24) bulls and heifers were compared. Samples of each muscle were taken within 1 h of slaughter to assess muscle fibre traits, while physio-chemical meat quality was assessed in each muscle at 48 h post mortem, followed by the sensory assessment of the muscles after 7 days of ageing. Despite identical raising conditions, bulls showed more favourable growth and slaughter performance, but heifers produced meat with more favourable sensory characteristics, as a result of a higher proportion of IIB fibres in their muscles, as well as a higher intramuscular fat content, and lower collagen content.
