Laurus nobilis, the leaves of which are used as a seasoning in cooking, is rich in active compounds such as phenols, flavonols and flavones, and has antioxidant and antimicrobial effects. This study evaluates the effects of the dietary supplementation with fat and dried bay leaves on growth performance and meat quality parameters of weaned rabbits. The trial lasted 56 days. At weaning (35 ± 2 days of age), 120 rabbits were divided into four groups (n=30) and fed four experimental diets: a control diet (CON); the same diet with 2.5% lard supplementation (CF); a control diet supplemented with 1 g/kg feed of dried bay leaf meal (BL); and a fat-enriched diet with 1 g/kg of dried bay leaf meal (BLF). Dietary fat negatively affected growth performance and final weight (P<0.01) and no effects of dried bay leaves were observed (P>0.05). The chemical composition, retinol and alpha-tocopherol content and lipid oxidative stability of Longissimus lumborum (LL) muscle were not affected (P>0.05) by lard or dried bay leaf supplementation. Dietary treatment with dried bay leaves reduced (P<0.01) the cholesterol content in the LL muscle compared with CF groups. An improvement in the sensory characteristics (juiciness and fibrous texture) was also observed in LL muscle from rabbits fed dried bay leaves. Further studies are required to determine the optimal dosage of dietary bay leaves and the length of dietary supplementation in order to clarify the mechanism of action of the active principles and to improve rabbit growth performance and meat quality.

月桂其叶子用作烹饪调味料，富含诸如酚，黄酮醇和黄酮等活性化合物，并具有抗氧化和抗菌作用。这项研究评估了饮食中添加脂肪和干月桂叶对断奶兔子的生长性能和肉品质参数的影响。审判持续了56天。在断奶时（35±2天大），将120只兔子分成四组（n = 30），并喂食四种实验饮食：对照饮食（CON）；对照组（CON）。相同的饮食加上2.5％的猪油补充（CF）；对照饮食，辅以1 g / kg干月桂叶粉（BL）饲料；以及1 g / kg干月桂叶粉（BLF）的富含脂肪的饮食。膳食脂肪对生长性能和最终重量有负面影响（P <0.01），而未观察到干燥的月桂叶的影响（P> 0.05）。化学成分猪油或干燥的月桂叶未对腰最长肌（LL）肌肉造成影响（P> 0.05）。与CF组相比，用干月桂叶进行的饮食处理可以降低（P <0.01）LL肌肉中的胆固醇含量。还观察到饲喂干月桂叶的兔子的LL肌肉的感觉特征（多汁和纤维质地）改善。需要进一步的研究来确定饮食中月桂叶的最佳剂量和膳食补充剂的长度，以阐明有效成分的作用机理并改善兔的生长性能和肉质。
