叶黄素衍生物替代叶黄素对肉鸡着色、组织色素含量、抗氧化、肝功能的影响
Effects of lutein derivatives substituted for lutein on coloring,tissue pigment content,antioxidation,and liver function of broilers
摘要
Abstract
To study the effects of dietary lutein and lutein derivatives on the skin color,tissue pigment content,and antioxidant capacity of yellow-feathered broilers,four hundred and thirty-two 37-day-old Sanhuang broilers were randomly divided into four groups with six replicates in each group and 18 chickens in each replicate.The control group was fed with wheat-soybean meal basal diet,and each experimental group was fed with lutein 40 mg/kg(lutein group),lutein 24 mg/kg and lutein derivative 16 mg/kg(lutein+lutein derivative group),lutein derivative 40 mg/kg(lutein derivative group).The trial period was 28 days.The results showed that the yellowness values of beak,shin,and underwing skin of broilers in each experimental group were significantly higher than those in the control group(P＜0.05).The total antioxidant capacity(T-AOC)in the serum of broilers in each experimental group was significantly increased(P＜0.05),and the activity of superoxide dismutase(SOD)in the liver was increased(P＞0.05).Serum cholesterol(TC)content of broilers in each experimental group increased significantly(P＜0.05).The expression of GPR143 gene in subwing skin of broilers decreased significantly(P＜0.05).The results show that lutein and lutein derivatives can improve the chromaticity of broiler skin and the antioxidant capacity of broiler body,and have no adverse effect on broiler liver.The partial replacement of lutein derivatives(16 mg/kg)cannot affect the coloring effect and antioxidant effect of lutein.关键词
