The present work evaluated the effects of feed supplementation with plant extracts (onion, cranberry) and a commercial essential oil product (Xtract™) on rabbit meat quality. Five groups of 48 weaned Grimaud female rabbits each received a control ration (C) or a diet supplemented with onion extract (500 or 1000 ppm), cranberry extracts (500 ppm) and essential oil product (100 ppm) alone or in combination. Microbiological quality was evaluated on whole hind legs stored under aerobic and anaerobic conditions at 4 °C. Growth performances, feed intake and both meat composition and quality were similar amongst the experimental groups. Anyhow, meat total phenolic content was significantly higher in all supplemented ones (P < 0.001). Diet supplementation effect was observed (P < 0.05) and microbial control was improved more importantly under anaerobic conditions, notably for Total Aerobic Mesophilic counts, presumptive Pseudomonas and Enterobacteriaceae (P < 0.03). Overall, supplementation with onion extract (500 ppm) suppressed microbial growth more effectively.
本研究评估了在饲料中添加植物提取物（洋葱、蔓越莓）和一种商业精油产品（Xtract™）对兔肉品质的影响。将 5 组 48 只断奶的 Grimaud 雌性兔分别饲喂基础日粮（C）或添加 500 或 1000 ppm 洋葱提取物、500 ppm 蔓越莓提取物和 100 ppm 精油产品的日粮，单独或组合添加。后腿整体在 4°C 下有氧和厌氧条件下储存，评估其微生物质量。生长性能、饲料摄入量以及肉的组成和质量在实验组之间相似。然而，所有添加组的总酚含量都显著更高（P < 0.001）。日粮添加效果显著（P < 0.05），在厌氧条件下微生物控制得到了更好的改善，特别是总需氧嗜温菌、假单胞菌和肠杆菌科（P < 0.03）。总体而言，添加 500 ppm 洋葱提取物可更有效地抑制微生物生长。
