Effects of hawthorn leaf flavonoids and stevioside on prouduction performance and serum biochemistry of laying hens
摘要
Abstract
This experiment investigated the effects of hawthorn leaf flavonoids and stevioside on the laying performance,egg quality and serum biochemistry of Jingfen No.6 laying hens.A total of 360 healthy 66-week-old hens were randomly assigned to four groups,each consisting of six replicates with 15 hens per group.The control group was fed a basal diet,while the treatment groups were supplemented with 120 mg/kg hawthorn leaf flavonoids,120 mg/kg stevioside,and 120 mg/kg hawthorn leaf flavonoids+120 mg/kg stevioside in the basal diet.The experiment consisted of a 2-week pre-test period followed by a 4-week main test period.The results showed that compared with the control group,the hawthorn leaf flavonoid,stevioside,and compound groups exhibited no significant differences in the laying performance of 68～72-week-old laying hens(P＞0.05).However,egg yolk color was significantly enhanced in all treatment groups(P＜0.05).Compared with the control group,the serum levels of triglyceride(TG)and low-density lipoprotein(LDL)in the hawthorn leaf flavonoids group were decreased by 22.03％and 13.88％,respectively(P＜0.05).In the stevioside group,the serum TG and LDL levels were reduced by 26.83％and 9.80％,respectively(P＜0.05).Notably,in the compound group,the serum levels of TG,LDL,and total cholesterol(TC)were decreased by 34.54％,52.65％,and 28.93％,respectively(P＜0.05).Furthermore,compared with the control group,the hepatic lipid droplet content in the hawthorn leaf flavonoid group,stevioside group,and compound group was reduced by 64.60％,67.60％,and 81.88％,respectively(P＜0.05).In conclusion,dietary supplementation with hawthorn leaf flavonoids and stevioside did not significantly affect the egg production performance of 68～72-week-old laying hens,but improved egg yolk color,serum biochemical parameters,and liver fat deposition.关键词
