The effects of distilled myrtle leaves (DML) intake on physiochemical traits, fatty acid profile and lipid oxidation of ewe’s sausage (Merguez) were investigated. Twenty‐seven ewes were divided into three homogenous groups. Ewes were fed hay and concentrate for control group (C). They received concentrate and M‐Hay pellets, containing 87% DML, as substitute to hay in MH group; for MC group, ewes received hay, concentrate and M‐Conc pellets having 30% DML in partial substitution to concentrate. They were slaughtered at the end of trial (90 days) with an average body weight of 42 kg. DML did not affect the physicochemical and sensory properties (P > 0.05) of Merguez; whereas, it increased lipid oxidative stability (P < 0.05). MH group showed the highest values of α‐tocopherol content, C18:2‐n6 fatty acid and polyunsaturated fatty acids. DML could be used in animal feeding to obtain higher meat product quality with better fatty acids content and antioxidant potential.

蒸馏桃金娘叶片的摄入量对母羊香肠的脂肪酸谱，理化特性和氧化稳定性的影响

研究了提取的紫薇叶（DML）对母羊香肠（Merguez）的理化特性，脂肪酸谱和脂质氧化的影响。二十七头母羊分为三组。给母羊饲喂干草并集中用于对照组（C）。他们收到了含有87％DML的精矿和M-Hay颗粒来代替MH组的干草。对于MC组，母羊接受了干草，精矿和M-Conc颗粒，其中30％DML被部分替代以进行精矿。他们在试验结束（90天）时被屠宰，平均体重为42公斤。DML不影响Merguez的理化和感官特性（P > 0.05）；而增加了脂质的氧化稳定性（P <0.05）。MH组的α-生育酚含量，C18：2-n6脂肪酸和多不饱和脂肪酸含量最高。DML可用于动物饲料中，从而获得更高的肉制品质量，并具有更好的脂肪酸含量和抗氧化能力。
