摘　　要：构建合理的意大利黑麦草饲喂畜禽模式是推广"意大利黑麦草—水稻"草田轮作这一典型生态农业系统的重要基础。试验对意大利黑麦草(Lolium multiflorum)代替部分精饲料饲养新西兰兔(Oryctolagus cuniculus)的效果进行研究。经过60天的分组饲喂试验发现,采用意大利黑麦草代替50%精饲料饲喂的新西兰兔其去皮重和胴体重分别提高6%和8%。意大利黑麦草饲喂新西兰兔的兔肉中脂肪含量显著低于精饲料组(P<0.05),且16种人体必需氨基酸含量明显高于精饲料组和杂草组,表明利用意大利黑麦草作为青饲料代替部分精饲料能够明显改善新西兰兔的兔肉品质。The Italian ryegrass rice rotation（IRR） system is a representative ecological agriculture ecosystem developed in South China. To further promote the application of the IRR system, it is of great importance to develop suitable utilization modes of Italian ryegrass in feeding livestock and poultry. In the present study, the effects of applying Italian ryegrass（Lolium multiflorum） as green feeder in replacing part of concentrate feed on the growth performance and meat quality of New Zealand rabbits（Oryctolagus cuniculus） were investigated. The 60 days feeding experiment showed that replacing 50% concentrate feed with Italian ryegrass could increase the tare weight and carcass weight by 6% and 8%, respectively. The application of Italian ryegrass significantly decreased the meat fat contents（P〈0.05） while increased the contents of amino acids in tested rabbits, indicating that application of Italian ryegrass as green feeder can improve the meat quality of New Zealand rabbits.
