This study aimed to evaluate the effect of feeding a mixture of herbal plants and spices enriched with special extracts and essential oils (phytogenic additives mixture) on feed intake, feed utilisation, blood chemistry, slaughter characteristics and caecal bacteria profile in rabbits. Ninety weaned unsexed V-Line rabbits, weighing 668.7 ± 8.2 g and aged 30 ± 1 days, were randomly allocated to three groups of 30 rabbits each and fed a basal diet without additives (Control rabbits) or supplemented with 0.5 mL (LA) or 1 mL (HA) of the additives mixture per litre of drinking water. Additives did not affect feed intake; however, the LA rabbits showed greater (P<0.001) feed conversion ratio compared to the other treatments. The LA treatment increased (P<0.01) final body weight and average daily gain compared to the control and HA treatments. Both the LA and HA treatments decreased (P<0.05) blood cholesterol, triglycerides and low-density lipoproteins; however, the LA treatment increased (P<0.05) high-density lipoproteins and total antioxidant capacity but decreased malondialdehyde (P<0.05) relative to the control treatment. Treatments did not affect carcass characteristics. The LA treatment followed by HA treatment increased (P<0.001) beneficial Lactobacillus spp. bacteria and decreased the concentrations of coliform bacteria and E. coli compared with the control treatment. It is concluded that additives mixture enhanced feed conversion and daily gain and positively altered caecal bacteria profile, with better effects of the low dose of the phytogenic additives mixture compared with the high dose.

这项研究旨在评估饲喂富含特殊提取物和精油（植物性添加剂混合物）的草本植物和香料混合物对兔子的采食量，饲料利用率，血液化学，屠宰特性和盲肠细菌分布的影响。将90只断奶的不性别V系兔子（重668.7±8.2 g，年龄30±1天）随机分为三组，每组30只，不添加添加剂（对照兔子）或补充0.5 mL（LA）或每升饮用水1毫升（HA）添加剂混合物。添加剂不影响采食量；然而，与其他处理相比，LA兔的饲料转化率更高（P < 0.001）。LA治疗增加（P <0.01）的最终体重和与对照组和HA治疗相比的平均日增重。LA和HA治疗均降低（P < 0.05）血液胆固醇，甘油三酸酯和低密度脂蛋白。然而，与对照相比，LA处理增加了高密度脂蛋白（P < 0.05）和总抗氧化能力，但丙二醛减少（P < 0.05）。处理不影响car体特征。LA治疗然后HA治疗可增加（P < 0.001）有益乳杆菌属。细菌并降低大肠菌和大肠杆菌的浓度与对照治疗相比。结论是，添加剂混合物提高了饲料转化率和日增重，并显着改变了盲肠细菌的分布，与高剂量相比，低剂量的植物性添加剂混合物具有更好的效果。
