The objective of this preliminary study was to evaluate the effects of partial replacement of soybean meal by lupins on lambs’ diets, on the carcass traits, meat characteristics, and meat fatty acid profile. Two trials were conducted: In trial 1, the soybean meal (control; C) was partially replaced by Lupinus albus or Lupinus luteus (50 g/kg; LA5 and LL5, respectively); in trial 2, lambs were fed four diets with graded levels of Lupinus luteus (0, 100, 150 and 200 g/kg; C, LL10, LL15, LL20, respectively). At the end of the feeding trials, animals were slaughtered to evaluate carcass characteristics and meat composition, including fatty acids. Carcass composition in tissues was not affected (p > 0.05) by diet in both trials. Additionally, no significant (p < 0.05) differences were observed in meat quality attributes between diets in trials 1 and 2. Overall, the Longissimus muscle’s fatty acid content was not affected by diet (p > 0.05) in both trials. Carcass and meat quality was overall comparable between lambs fed with soybean meal and lupins, indicating the latter as a potential alternative protein source. However, the lack of significant differences could also be attributed to the small sample size.
这项初步研究的目的是评估用羽扇豆部分替代豆粕对羔羊日粮、胴体性状、肉品质和肉脂肪酸谱的影响。进行了两项试验：在试验1中，用白羽扇豆或黄羽扇豆分别部分替代豆粕（对照组；C）（分别为50 g/kg；LA5和LL5）；在试验2中，给羔羊饲喂四种含有不同水平黄羽扇豆的日粮（分别为0、100、150和200 g/kg；C、LL10、LL15、LL20）。在饲养试验结束时，宰杀动物以评估胴体特征和肉成分，包括脂肪酸。在两项试验中，日粮对组织中的胴体成分均无影响（p>0.05）。此外，在试验1和试验2中，日粮之间的肉品质属性未观察到显著（p<0.05）差异。总体而言，在两项试验中，日粮对背最长肌的脂肪酸含量均无影响（p>0.05）。饲喂豆粕和羽扇豆的羔羊的胴体和肉品质总体相当，表明羽扇豆是一种潜在的替代蛋白质来源。然而，缺乏显著差异也可能归因于样本量小。
