To investigate the potential of eland for meat production, the yield, physical quality and chemical composition of seven muscles were characterized from both male (n = 6) and female (n = 6) carcasses. Although carcass weights did not differ, cows had greater biceps femoris (BF), semitendinosus (ST) and supraspinatus (SS) muscle yields. The semimembranosus (SM) from cows had the greatest drip loss and were more yellow (b*) than all muscles evaluated from both sexes. Shear force measurements showed no effect of sex but large variations between muscles existed (65.5 to 97.6 N). Moisture content was greater within the BF, SS, ST and infraspinatus (IS) than the longissimus thoracis et lumborum (LTL) and SM. The LTL and IS had the lowest intramuscular fat content, while the LTL and SM muscle had the highest crude protein content. Sex had little effect on eland meat composition, showing potential for the meat of both sexes to be marketed as a lean meat source.
为了研究大羚羊用于肉类生产的潜力，本研究从雄性（n=6）和雌性（n=6）胴体中分别对 7 块肌肉的产肉率、物理质量和化学组成进行了特征描述。尽管胴体重量没有差异，但母牛的二头肌（BF）、半腱肌（ST）和冈上肌（SS）产肉率更高。母牛的半膜肌（SM）滴水损失最大，并且比所有雌雄两性评估的肌肉都更黄（b*）。剪切力测量结果显示性别没有影响，但肌肉之间存在很大差异（65.5 至 97.6 N）。BF、SS、ST 和冈下肌（IS）的水分含量高于胸腰椎最长肌（LTL）和 SM。LTL 和 IS 肌肉的肌内脂肪含量最低，而 LTL 和 SM 肌肉的粗蛋白含量最高。性别的影响很小，表明雌雄两性的大羚羊肉都有潜力作为瘦肉源进行销售。
