The effects of immunocastration, pelvic suspension and wet ageing on the meat quality of the longissimus lumborum et thoracis (LTL) and biceps femoris (BF) muscles of male common eland were evaluated. Ten subadult males were either immunocastrated (n = 5) or remained intact (n = 5) throughout a four-month growth trial, after which their carcass sides were randomly allocated to either pelvic- or Achilles-suspension. The LTL and BF were further aged for 14 days, measuring changes in the physical quality weekly. The sensory quality of the LTL and BF were determined after ageing (8/9 days, respectively). Immunocastration had minimal effects on the meat quality of male eland, but pelvic suspension decreased the shear force. All muscles reached minimum shear force after seven days of ageing, and the panellists ranked the pelvic-suspended muscles higher for tenderness traits. Incorporating pelvic suspension and wet ageing into the commercial processing of eland carcasses should be considered to improve overall meat quality.

事前和验尸策略可提高从养殖的雄性普通大羚羊(Taurotragus oryx)收获的高价值肌肉的肉质。

评估了免疫cast割,骨盆悬吊和湿老化对雄性普通大羚羊腰最长胸(LTL)和股二头肌(BF)肌肉质量的影响。十名亚成年男性被免疫cast割(n  = 5)或保持完整(n = 5)在为期四个月的生长试验中,之后将其their体侧随机分配到骨盆或跟腱悬吊系统。零担和高炉进一步老化14天,每周测量一次身体素质的变化。老化后(分别为8/9天)确定LTL和BF的感官质量。免疫铸造对雄性大羚羊肉品质的影响很小,但骨盆悬吊降低了剪切力。老化7天后,所有肌肉均达到最小剪切力,并且小组成员对骨盆悬吊肌肉的压痛性状排名较高。应考虑将骨盆悬浮液和湿法陈化法加入大肠land体的商业加工中,以改善整体肉质。
