摘要: 试验旨在研究槲皮素对蛋鸡生产性能及脂类代谢的影响。选择240只29周龄的海赛蛋鸡,随机分为4组,每组6个重复,每个重复10只鸡。对照组饲喂基础日粮,试验Ⅰ、Ⅱ、Ⅲ组分别在基础日粮中添加0.02%、0.04%和0.06%槲皮素,试验期为8周。结果表明,与对照组相比,试验Ⅰ组槲皮素能显著提高蛋鸡产蛋率与血清胰岛素含量(P<0.05),显著降低肝脏粗脂肪含量(P<0.05);试验Ⅱ组槲皮素显著提高了蛋黄粗脂肪、蛋黄总磷脂、血清胰岛素和雌二醇的含量(P<0.05),显著降低料蛋比、肝脏粗脂肪含量(P<0.05),且低密度脂蛋白胆固醇有下降的趋势(P>0.05);试验Ⅲ组槲皮素能提高蛋鸡产蛋率、蛋黄粗脂肪与总磷脂的含量,但差异不显著(P>0.05)。因此,0.04%槲皮素为适宜添加量,能提高蛋鸡生产性能和蛋黄中磷脂含量,降低肝脏粗脂肪含量。

Abstract: The trial was designed to study effect of quercetin on production performance of laying hens,and explored mechanism of action at lipids metabolism. Two hundred and forty laying hens of 29-week-age were randomly allotted into the control and three treatment groups. Each group had six replicates and ten laying hens per replicate. The control group was fed with the basal diet and the test groups Ⅰ,Ⅱ,Ⅲ were fed with the basal diets supplemented with 0.02%,0.04% and 0.06% quercetin,respectively. The experiment lasted for 8 weeks. The results showed that compared with the control group,the test group Ⅰincreased significantly laying rate and serum insulin content,decreased significantly lipid content in liver(P<0.05),the test group Ⅱ increased significantly content of lipid and total phospholipid in yolk,serum estradiol and insulin content,decreased significantly feed-egg ratio, lipid content in liver (P<0.05), and serum TG (P<0.01). There was a decreasing trend in LDL-C content(P>0.05),the test group Ⅲ increased laying rate,content of lipid and total phospholipid in yolk, but there were no significant differences(P>0.05). In conclusion,0.04% quercetin improved production performance and phospholipid content in yolk,decreased lipid content in liver.

Key words: quercetin; production performance; lipids metabolism; laying hens
