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。

Abstract

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 (P>0.05); during 5 to 7 weeks of the experiment, the laying rate of laying hens in experimental group was significantly increased (P<0.01), the ratio of feed to egg and deformed eggs ratio were significantly decreased (P<0.05). 2) Compared with the control group, the laying rate of laying hens in experimental group at the 5th, 6th and 7th week was significantly increased (P<0.05 or P<0.01). 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 (P<0.05). 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.
