The carcass yields and physiochemical meat quality characteristics of six different muscles (biceps femoris, infraspinatus, longissimus thoracis et lumborum, semimembranosus, semitendinosus, supraspinatus) for different sex and age groups of gemsbok antelope were determined. No live weight nor dressing percentage differences were observed for the different sex groups. While muscles, age and sex had an influence on the physiochemical parameters investigated, these differences were minor. The CIE Lab colour values for all muscles, age and sexes were in line with those deemed acceptable for game meat, while mean crude protein (20.7%) and fat (1.6%) levels were typical of game species. Discriminant analysis revealed no differentiation among the muscle groups for the variables measured. Thus, at similar live weights, male and female (sub-adult) gemsbok can be considered of equivalent meat quality and marketed accordingly.
对不同性别和年龄组的大羚羊的 6 种不同肌肉(股二头肌、肩胛下肌、胸腰椎最长肌、半腱肌、半膜肌、冈上肌)的胴体产量和生理化学肉质特性进行了测定。不同性别组之间的活重和屠宰率没有差异。尽管肌肉、年龄和性别对所研究的生理化学参数有影响,但这些差异很小。所有肌肉、年龄和性别的 CIE Lab 颜色值都符合野味肉的可接受标准,而平均粗蛋白(20.7%)和脂肪(1.6%)水平则是野味物种的典型特征。判别分析显示,所测量的变量在肌肉群之间没有差异。因此,在相似的活重下,雄性和雌性(亚成体)大羚羊的肉质质量可以认为是相当的,并相应地进行销售。
