In Norway, most lambs are slaughtered at the end of the grazing season in September. An increased demand for fresh meat during the off-season may change this pattern. Castration of male lambs is not permitted, and off-season slaughtering may affect the acceptability of the meat. The objective of this study was to determine the effect of gender and the interaction between gender and diet on meat quality from Norwegian White Sheep lambs slaughtered in September. In two different experiments, 22 and 29 males compared with 22 and 46 female lambs, respectively, were used. Loin samples of M. Longissimus dorsi were analysed for sensory profile and fatty acid composition. Meat from male lambs in Experiment 2 had higher scores for cloying and rancid flavour, and lower scores for sour and sweet taste compared to meat from female lambs. It is concluded that even at the normal slaughtering time in September, significant differences between genders may occur.
在挪威，大多数羔羊在 9 月的放牧季节结束时被屠宰。淡季对鲜肉的需求增加可能会改变这种模式。不允许对雄性羔羊进行去势，淡季屠宰可能会影响肉的可接受性。本研究的目的是确定性别的影响以及性别与饮食之间的相互作用对 9 月屠宰的挪威白绵羊羔羊肉质的影响。在两个不同的实验中，分别使用了 22 只雄性和 29 只雄性与 22 只雌性和 46 只雌性羔羊进行比较。对背最长肌的腰肉样品进行感官分析和脂肪酸组成分析。与雌性羔羊的肉相比，来自雄性羔羊的肉在实验 2 中具有更高的粘腻味和腐臭味评分，以及更低的酸味和甜味评分。研究结论认为，即使在 9 月的正常屠宰时间，性别之间也可能存在显著差异。
