摘要 选择65周龄健康海兰褐蛋鸡150只,采用单因素完全随机分组试验设计,随机分为对照组(基础日粮)、试验组Ⅰ(基础日粮+0.5%女贞子粉)、试验组Ⅱ(基础日粮+1%女贞子粉)。每组设5个重复,每个重复10只蛋鸡。试验期为8周。本试验研究了女贞子粉对产蛋后期蛋鸡生产性能、免疫功能和血液生化指标的影响。结果表明,与对照组相比,料蛋比试验组Ⅰ、Ⅱ显著降低(P<0.05)。平均日产蛋量和产蛋率试验组Ⅱ比对照组分别显著提高了20.09%和18.75%(P<0.05)。试验组Ⅱ抗体效价显著高于对照组(P<0.05)。试验组Ⅰ、Ⅱ的淋巴细胞转化率比对照组别提高了50.83%和49.85%(P<0.05)。TC和LDL含量试验组Ⅰ、Ⅱ显著降低(P<0.05)。HDL含量试验组Ⅰ比对照组显著提高了27.27%(P<0.05)。日粮中添加女贞子粉能够提高产蛋后期蛋鸡的生产性能和免疫功能,并具有调节脂类代谢的功能。 To study the effects of Ligustrum lucidum(LL) on production performance,immunity and serum biochemical indexes of hens at late laying stage,one hundred and fifty 65-weeks Hyline brown hens were randomly allotted to 3 treatments with 5 replicates pens pretreatment and 10 birds per pen.The control group was fed a basal diet,the experimental groupⅠ,Ⅱ were fed the basal diet supplemented with 0.5%,1% LL,respectively.The experiment lasted 8 weeks.The results showed that feed-egg ratio of experimental groupⅠ,Ⅱ were significantly reduced (P0.05) compared with the control.Laying rate and average daily egg production of experimental group Ⅱ were significantly increased by 20.09% and 18.75% respectively (P0.05) compared with the control.Antibody titres to newcastle disease virus of experimental groupⅡ was significantly increased (P0.05) compared with the control.Lymphocyte transformation rate of experimental groupⅠ,Ⅱwere significantly increased by 49.85% and 50.83% respectively(P0.05) compared with control.The level of TC and LDL of experimental group Ⅰ,Ⅱ were significantly reduced (P0.05) compared with the control.The level of HDL of experimental group Ⅰ was significantly increased by 27.27% compared with the control.Basal diet supplemented with LL could increase performance,immunity and improved lipid metabolism of hens at late laying stage.
