Abstract

This study investigated the effect of a dietary combination of selenium and olive leaves on rabbit health status in order to evaluate the potential use of these combinations as functional ingredients in feed and food. Sixty weaning rabbits were fed with three diets: control feed (C), control feed + 10% normal olive leaves (OL), or olive leaves enriched in Se (2.17 mg Se/kg d.m.; SeOL). The plasma mineral profile, antioxidant status, and leukocyte DNA damage were determined. Inorganic Se was the most abundant form in the OL diet, while the organic one was higher in SeOL than C and OL. A similar trend was found in the plasma. Protein oxidation showed higher values in both supplemented groups; in addition, dietary Se led to a significant improvement (+ 40%) in ferric reducing ability of plasma (FRAP). A marked reduction in DNA damage (9-fold) was observed in the SeOL group compared to C. The combination of selenium and olive leaves in the diet of growing rabbits increased plasma SeMet and FRAP and reduced leukocyte DNA damage.

摘要

本研究调查了硒与橄榄叶的饮食组合对家兔健康状况的影响，以评估这些组合作为饲料和食品中功能成分的潜在用途。60只断奶家兔被喂食三种日粮：对照饲料（C）、对照饲料+10%普通橄榄叶（OL）或富含硒的橄榄叶（2.17毫克硒/千克干物质；SeOL）。测定了血浆矿物质谱、抗氧化状态和白细胞DNA损伤情况。无机硒是OL日粮中最丰富的形式，而有机硒在SeOL中高于C组和OL组。血浆中也发现了类似的趋势。两个补充组的蛋白质氧化值均较高；此外，日粮中的硒使血浆铁还原能力（FRAP）显著提高（+40%）。与C组相比，SeOL组的DNA损伤明显减少（9倍）。生长兔日粮中硒与橄榄叶的组合增加了血浆硒蛋氨酸和FRAP，并减少了白细胞DNA损伤。
