Effects of chronological age (0, 2, 4, 6, and 8 permanent Incisors [PI]) and sex were evaluated on meat quality of the Longissimus lumborum muscle using 130 beef-type animals. Hot carcass weight (HCW), intramuscular fat (IF), pH, tenderness (WBS), color (L*, a*, and b*), water holding capacity and sensory properties (tenderness, juiciness, and general acceptance) were evaluated. Females had lower HCW (178 vs. 252 kg; P 0.05). To better understand how age and sex affect meat quality, pH variations must be addressed.
