The lipid analysis of commercial lamb's meat, from two main Moroccan production areas Middle Atlas and highlands of eastern Morocco, was conducted. This study concerns the lipid quality of sheep meat from Beni Guil (BG) and Timahdite (Ti) as indigenous breeds and that of the Ouled Djellal (ODj) breed of Algerian origin. To study the effect of the geographical area, the meat samples from the Beni Guil breed were taken in the two main locations of this breed: in the region of Ain Beni Mathar (BGA) and that of Tendrara (BGT). The fatty acid profiles of the sheep meats analyzed showed the following: (i) polyunsaturated fatty acid (PUFA) richness was of 12.87 % and 20.59 % respectively for BGA and BGT breeds; (ii) polyunsaturated saturated fatty acid ratios were ranged between 0.28 to 0.50 respectively for BGA and Ti breed; and (iii) PUFA- content was 1.71 % for ODj breed and 2.13 % for BGA. Thus, the PUFA- PUFA ratios range between 4.92 and 9.6 for BGA and Ti sheep meat, respectively. The cholesterol content was 0.08 % and 0.12 % of fresh meat respectively for ODj and BGA. Finally, meats of BGA and ODj have similar thrombogenicity (1.23 and 1.27 respectively) and atherogenicity indices (0.71 and 0.68 respectively). Statistically, these values were significantly higher than those registered for Ti breed (IT: 1.04 and AI: 0.51). In conclusion, from a nutritional point of view, it can be deduced that these meats have an interesting lipid quality due to their richness in desirable fatty acid (UFA C18 : 0).
对来自摩洛哥两个主要产区——中阿特拉斯和摩洛哥东部高地的商业羔羊肉进行了脂质分析。本研究关注作为本土品种的贝尼吉尔（BG）和蒂马赫迪特（Ti）以及阿尔及利亚原产的乌尔德杰拉尔（ODj）品种的羊肉脂质质量。为研究地理区域的影响，从贝尼吉尔品种的两个主要产地采集了该品种的肉样：艾因贝尼马塔尔地区（BGA）和滕德拉拉地区（BGT）。所分析的绵羊肉的脂肪酸谱显示如下：（i）BGA和BGT品种的多不饱和脂肪酸（PUFA）含量分别为12.87%和20.59%；（ii）BGA和Ti品种的多不饱和脂肪酸与饱和脂肪酸的比率分别在0.28至0.50之间；（iii）ODj品种的PUFA-含量为1.71%，BGA品种为2.13%。因此，BGA和Ti绵羊肉的PUFA-与PUFA的比率分别在4.92至9.6之间。ODj和BGA鲜肉的胆固醇含量分别为0.08%和0.12%。最后，BGA和ODj肉的血栓形成性（分别为1.23和1.27）和动脉粥样硬化指数（分别为0.71和0.68）相似。从统计学上看，这些值显著高于Ti品种记录的值（IT：1.04和AI：0.51）。总之，从营养角度可以推断，这些肉因其富含理想脂肪酸（UFA与C18:0）而具有良好的脂质质量。
