摘要

本研究旨在探讨全亚麻籽（WFS）、鱼油（FO）以及不同来源的硒、锌和铁对蛋鸡脂质代谢物、抗氧化状态、免疫力、蛋黄矿物质（硒、锌和铁）和脂肪酸以及鸡蛋脂质和健康指数的影响。共有 144 只蛋鸡被分为 6 组，每组 4 只，重复 6 次。产蛋鸡饲喂的日粮包括 0、7.5 % 全亚麻籽（WFS）+1.5 % 鱼油（FO）、7.5 % WFS+1.5 % FO+175 mg kg-1 维生素 E（VE）、7.5 % WFS+1.5 % FO+175 mg kg-1 VE + 无机来源的硒、锌和铁（ISeZnFe）、7.在 40 至 50 周龄期间，分别添加了 7.5 %WFS+1.5 % FO+175 mg kg-1 VE+ Se、Zn 和 Fe 的有机来源（OSeZnFe）和 7.5 %WFS+1.5 % FO+175 mg kg-1 VE+ Se、Zn 和 Fe 的纳米来源（NSeZnFe）。结果表明，与对照组相比，添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.5 %FO+VE+NSeZnFe 可提高血清中高密度脂蛋白胆固醇的浓度和高密度脂蛋白/低密度脂蛋白比率，同时降低低密度脂蛋白胆固醇和高胆固醇血症指数（RHCH）。膳食中添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.5 %FO+VE+NSeZnFe 可提高总抗氧化能力和维生素 E 的浓度，降低血清和鸡蛋中丙二醛（MDA）的浓度。有趣的是，膳食中添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.有趣的是，膳食中添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.5 %FO+VE+NSeZnFe 会增加蛋黄中的α-亚麻酸（ALA）、二十碳五烯酸（EPA）、二十二碳五烯酸（DPA）、二十二碳六烯酸（DHA）和总 n-3 PUFAs 的浓度，同时降低蛋黄中的花生四烯酸（ARA），而 n-6/n-3 PUFAs 的比例则显著下降。此外，添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.5 %FO+VE+NSeZnFe 可改善鸡蛋的健康指数。由此可以得出结论：在母鸡日粮中添加 7.5 %WFS+1.5 %FO+VE+OSeZnFe 或 7.5 %WFS+1.5 %FO+VE+NSeZnFe 对血清中的抗氧化性和蛋黄中的抗氧化性有积极影响，同时还能改善蛋黄中的脂类、脂肪酸及其相关的健康和营养指标。

Enhancing the nutritional values of egg yolks of laying hens by different dietary sources of omega-3 fatty acids, vitamin e and trace elements

The present study aims to investigate the effect of whole flaxseed (WFS), fish oil (FO), and different sources of Se, Zn, and Fe on lipid metabolites, antioxidant status, immunity, egg yolks’ minerals (Se, Zn and Fe) and fatty acids and eggs’ lipid and health index in laying hens. A total of 144 hens were divided into 6 groups with 6 replicated of 4 hens each. The laying hens were fed diets containing 0, 7.5 % whole flaxseed (WFS)+1.5 % fish oil (FO), 7.5 %WFS+1.5 % FO+175 mg kg^-1 vitamin E (VE), 7.5 %WFS+1.5 % FO+ 175 mg kg^-1 VE +inorganic sources of Se, Zn, and Fe (ISeZnFe), 7.5 %WFS+1.5 % FO+175 mg kg^-1 VE+ organic sources of Se, Zn, and Fe (OSeZnFe) and 7.5 %WFS+1.5 % FO+ 175 mg kg^-1 VE +nano-source of Se, Zn, and Fe (NSeZnFe) from 40 to 50 weeks of age. Results clarified that incorporation of 7.5 %WFS+1.5 %FO+VE+OSeZnFe or 7.5 %WFS+1.5 %FO+VE+NSeZnFe increased serum concentration of HDL-cholesterol and HDL/LDL ratio, while reduced LDL-cholesterol and the hypercholesteremia index (RHCH) in comparison with control. Dietary 7.5 %WFS+1.5 %FO+VE+OSeZnFe or 7.5 %WFS+1.5 %FO+VE+NSeZnFe increased concentrations of total antioxidants capacity and vitamin E and reduced concentrations of malonaldehyde (MDA) in blood serum and egg contents. Interestingly, dietary inclusion of 7.5 %WFS+1.5 %FO+VE+OSeZnFe, or 7.5 %WFS+1.5 %FO+VE+NSeZnFe increased α-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), and total n-3 PUFAs concentrations in egg yolk, while reduced arachidonic acid (ARA) in the egg yolks, whereas n-6/n-3 PUFAs ratio was decreased significantly. Moreover, incorporation of 7.5 %WFS+1.5 %FO+VE+OSeZnFe, or 7.5 %WFS+1.5 %FO+VE+NSeZnFe improved egg health indices. It might be concluded that, inclusion of 7.5 %WFS+1.5 %FO+VE+OSeZnFe, or 7.5 %WFS+1.5 %FO+VE+NSeZnFe in hens’ diets had a positive effect on antioxidative properties in blood serum and eggs yolks contents; at the same time, it improved the egg yolk lipids, fatty acids and its related health and nutritional indices.
