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.
