Carnosine and Acyl Carnitines as Metabolic Determinants of Muscle Phenotypic Differences Between Longissimus Dorsi and Triceps Brachii in Hanzhong Sheep

Muscle traits are critical determinants of meat quality and productivity in sheep, influenced by both breed and anatomical region. Hanzhong sheep, an indigenous Chinese breed, are prized for tender, low-odor meat; yet, the molecular mechanisms underlying these traits remain poorly understood. In this study, we integrated meat quality assessment with metabolomic and transcriptomic profiling of the longissimus dorsi (HZ-B) and tri- ceps brachii (HZ-T) muscles to elucidate biochemical and...
