Muscles (n=18) were dissected from each side of 20 lamb carcasses to characterize physical, chemical, and histological traits. Muscles from the right sides were used to measure color values, expressible moisture, pH, total collagen content, and sarcomere length. Muscles from the left sides were aged for 7d and used to determine Warner-Bratzler shear (WBS) force values. The M. adductor and M. semimembranosus had the darkest colored lean (lowest L(∗) values), whereas the M. latissimus dorsi and M. tensor fasciae latae had the lightest colored lean (highest L(∗) values). The M. triceps brachii, M. pectoralis profundus, and M. latissimus dorsi had among the lowest numerical expressible moistures whereas the M. adductor and the M. longissimus lumborum had among the highest. The M. infraspinatus was found to have the highest collagen content (9.0mg/g) and the M. psoas major had the longest sarcomere length (3.1μm). Of the muscles sampled, the M. serratus ventralis had one the lowest WBS values (21.8N) and the M. semimembranosus the highest (42.6N). On average, the largest muscles identified were the M. gluteobiceps, M. gluteus medius, M. longissimus lumborum, M. longissimus thoracis, and M. semimembranosus, which would likely be suitable in terms of physical dimensions for used in a variety of individual muscle applications. Other muscles, however, such as the M. teres major and M. tensor fasciae latae, may be too small in size and dimension to be used for individual application.
从20只羔羊胴体的每一侧解剖出肌肉（n = 18），以表征其物理、化学和组织学特性。右侧的肌肉用于测量颜色值、可表达水分、pH值、总胶原蛋白含量和肌节长度。左侧的肌肉经过7天的成熟处理，用于测定沃纳-布拉茨勒剪切（WBS）力值。内收肌和半膜肌的瘦肉颜色最深（L()值最低），而背阔肌和阔筋膜张肌的瘦肉颜色最浅（L()值最高）。肱三头肌、胸深肌和背阔肌的可表达水分数值最低，而内收肌和腰大肌的可表达水分数值最高。发现冈下肌的胶原蛋白含量最高（9.0mg/g），腰大肌的肌节长度最长（3.1μm）。在采样的肌肉中，腹侧锯肌的WBS值最低（21.8N），半膜肌的WBS值最高（42.6N）。平均而言，确定的最大肌肉是臀二头肌、臀中肌、腰大肌、胸最长肌和半膜肌，就物理尺寸而言，它们可能适用于各种单个肌肉应用。然而，其他肌肉，如大圆肌和阔筋膜张肌，其尺寸可能太小，无法用于单个应用。
