摘　　要：本试验旨在研究生姜提取物对蛋鸡生产性能和蛋品质的影响。选择600只25周龄的海兰褐蛋鸡,随机分成2个组,每组4个重复,每个重复75只鸡。对照组饲喂基础饲粮,试验组在基础饲粮中添加0.1%的生姜提取物。预试期1周,正试期7周。结果表明:1)与对照组相比,试验第1~4周,试验组蛋鸡生产性能指标没有显著差异(P>0.05);试验第5~7周,试验组蛋鸡产蛋率极显著提高(P<0.01),料蛋比、畸形蛋比率均显著降低(P<0.05)。2)与对照组相比,试验组蛋鸡第5、6、7周产蛋率显著或极显著提高(P<0.05或P<0.01)。3)与对照组相比,试验组蛋鸡蛋形指数极显著升高(P<0.01),蛋壳重、蛋壳厚度均显著升高(P<0.05)。由此可见,饲粮中添加0.1%生姜提取物能够提高蛋鸡的生产性能,并对蛋品质有一定的改善作用。This experiment was conducted to investigate the effects of ginger extract on production performance and egg quality of laying hens. A total of 600 Hy-Line brown laying hens aged of twenty-five-week-old were randomly divided into 2 groups with 4 replicates per group and 75 laying hens per replicate. Hens in the control group were fed a basal diet,and others in the experimental group were fed basal diet supplemented with 0.1%ginger extract. The adaptation period lasted for 1 week,and the formal period lasted for 7 weeks. The results showed as follows： 1） compared with the control group,during 1 to 4 weeks of the experiment,the production performance indexes of laying hens in experimental group had no significant difference（ P0.05）; during5 to 7 weeks of the experiment,the laying rate of laying hens in experimental group was significantly increased（ P0.01）,the ratio of feed to egg and deformed eggs ratio were significantly decreased（ P0.05）. 2） Compared with the control group,the laying rate of laying hens in experimental group at the 5 th,6 th and 7 th week was significantly increased（ P0.05 or P0.01）. 3） Compared with the control group,the egg shape index of laying hens in experimental group was significantly increased（ P 0. 01）,the eggshell weight and eggshell thickness were significantly increased（ P0.05）. In conclusion,dietary supplemented with 0.1% ginger extract can improve the production performance of laying hens,and also has beneficial effect on egg quality of laying hens.
