Abstract

This experiment was conducted to investigate the effects of Qicao extract on laying performance, egg quality and cholesterol metabolism of laying hens. A total of 3 360 Dawu Jinfeng laying hens aged at 45 weeks were randomly divided into 2 groups with 12 replicates per group and 140 hens per replicate. Hens in the control group were fed a basal diet, and the others in the experimental group were fed the basal diet supplemented with 400 mg/kg Qicao extract. The experiment lasted for 12 weeks. The results showed as follows:1) on weeks 8 and 12 of the experiment, the laying rate and the ratio of feed to egg of laying hens in experimental group were significantly higher than those in the control group (P<0.05). 2) On weeks 8 and 12 of the experiment, the albumen height and Haugh unit of egg in experimental group were significantly higher than those in the control group (P<0.05); on week 12 of the experiment, the eggshell strength and eggshell thickness of egg in experimental group were significantly higher than those in the control group (P<0.05). 3) On week 12 of the experiment, the serum total cholesterol content of laying hens in experimental group was significantly lower than that in the control group (P<0.05), the gene expression levels of 3-hydroxy-3methylglutary CoA reductase (HMGR) in liver and low density lipoprotein receptor (VLDLR) in ovary of laying hens in experimental group were significantly lower than those in the control group (P<0.05). 4) On weeks 4 to 12 of the experiment, the yolk cholesterol content of egg in experimental group was gradually decreased; on week 12 of the experiment, the yolk cholesterol content of egg in experimental group was significantly lower than that in the control group (P<0.05). In conclusion, dietary supplemented Qicao extract can increase the laying performance and egg quality of laying hens, and decrease the yolk cholesterol content of egg by regulating the fat metabolism indices in serum and inhibiting the expression of HMGR and VLDLR genes.
