摘　　要：通过在鹌鹑日粮中添加不同剂量辣木叶粉,探究其对鹌鹑生产性能、免疫功能及血清抗氧化指标的影响。结果表明:添加2%、4%辣木叶粉能显著提高鹌鹑15、21、28日龄体质量(P<0.05),添加4%辣木叶粉能显著提高鹌鹑35日龄体质量(P<0.05);添加2%辣木叶粉能显著提高鹌鹑7～35日龄平均日增质量,显著降低料质量比(P<0.05);添加4%辣木叶粉能显著提高7～35日龄鹌鹑平均日增质量,显著降低料质量比(P<0.05);添加2%、4%、8%辣木叶粉能显著降低鹌鹑7～35日龄料质量比(P<0.05)。21日龄时,添加4%、8%辣木叶粉显著提高鹌鹑脾脏指数、血清总超氧化物歧化酶活力(P<0.05),显著降低血清丙二醛含量(P<0.05);添加8%辣木叶粉显著提高法氏囊指数、血清新城疫抗体水平和总抗氧化能力(P<0.05)。35日龄时,添加4%、8%辣木叶粉显著提高脾脏指数、法氏囊指数、血清新城疫抗体水平、白介素-2含量、γ-干扰素含量和总抗氧化能力(P<0.05),显著降低丙二醛含量(P<0.05);添加8%辣木叶粉显著提高胸腺指数(P<0.05)。综合考虑,4%辣木叶粉为最佳添加剂量。In order to study the effects of Moringa oleifera leaf powder on production performance, immune function and serum antioxidant indices of quails, different doses of M. oleifera leaf powder were added into basal diets. The results showed that the groups within 2% and 4% M. oleifera leaf power could significantly improve the average body mass of 15, 21 and 28 day-old quails (P<0.05), and the group within 4% M. oleifera leaf powder could significantly improve the average body mass of 35 day-old quails (P<0.05);the group of 2% M. oleifera leaf powder could significantly improve the average daily gain and decrease the feed conversion ratio of 7-35 day-old quails (P<0.05);the group of 4% M. oleifera leaf powder could significantly improve the average daily gain of 7-35 day-old quails and decrease the feed conversion ratio in the whole experimental period (P< 0.05);the group of 2%,4%,8% M. oleifera leaf powder could significantly decrease the feed conversion ratio of 7-35 day-old quails (P<0.05). At the age of 21 day-old, the groups of 4% and 8% M. oleifera leaf powder could significantly improve the spleen index and serum total superoxide dismutase activity and decrease the serum MDA content (P<0.05);the group of 8% M. oleifera leaf powder could significantly improve the bursa index, Newcastle disease virus antibody (NDV-Ab) level and serum total antioxidant capacity (P<0.05). At the age of 35 day-old, the group of 4% and 8% M. oleifera leaf powder could significantly improve the spleen index, the bursa index, NDV-Ab level, contents of IL-2 and interferon (INF)-γ, and total antioxidant capacity and decrease the serum MDA content (P<0.05);the group of 8% M. oleifera leaf powder could significantly improve the thymus index (P<0.05). In conclusion, the best amount of addition is 4% of M. oleifera leaf powder.
