The fatty acid (FA) profiles of lamb muscle and adipose tissue originating from ten different grazing areas in North Macedonia and an assessment of whether the meat origin could be distinguished on the basis of FA profile are presented. Muscle and adipose tissues of three-month-old male lambs (crossbreds of autochthonous Ovcepolian and Württemberg) reared on spring pastures were studied. Statistically significant differences in the individual FA contents, FA groups and FA ratios were observed between lamb tissues from the different geographic regions. Canonical discriminant analysis showed there was a significant linear divergence between tissues from almost all examined regions. The greatest weight in the differentiation of the different areas showed fatty acid ratios, C18:3n3, C18:1n9c and C20:5n3 for the muscle tissue, as well as C18:1n9c, C18:2n6c, C16:1 and C17:1 for the adipose tissue. This showed that the FA composition of muscle and adipose tissue obtained from lambs reared on pasture could serve as a useful indicator to aid differentiation of its geographic origin but it should be confirmed through further replicated studies.

提出了来自北马其顿的十个不同放牧区的羔羊肌肉和脂肪组织的脂肪酸（FA）谱，并评估了是否可以根据FA谱区分肉的起源。三个月大的公羊羔的肌肉和脂肪组织（土生的奥维波利和符腾堡州的杂交种））在春季牧场饲养的动物进行了研究。在来自不同地理区域的羔羊组织之间，观察到个体FA含量，FA组和FA比在统计学上的显着差异。典范判别分析显示，几乎所有检查区域的组织之间都存在明显的线性差异。在不同区域的分化中，最大的重量显示出肌肉组织的脂肪酸比率，C18：3n3，C18：1n9c和C20：5n3，以及C18：1n9c，C18：2n6c，C16：1和C17：1脂肪组织。这表明从在牧场上饲养的羔羊获得的肌肉和脂肪组织的FA组成可以作为有助于区分其地理起源的有用指标，但应通过进一步的重复研究加以证实。
