Effect of Selenium Nanoparticles on Performance, Antioxidant Status, Blood Parameters and Oxidative Stability of Eggs in Laying Hens

摘要: Introduction Selenium is an essential trace element that is indispensable for normal functioning of the body and thus plays a critical role in the maintenance of optimal health. It is known to have important role in a number of biological functions, such as antioxidant defense, immune function, reproduction and thyroid hormone metabolism. Eggs and meat are considered to be good sources of Se in human diet. Egg Se content can easily be manipulated to give increased levels, when organic selenium as selenomethionine is included in layer diets. Recently, Nano-Se which is bright red, highly stable, soluble has attracted widespread attention because nanometer particulates exhibit novel characteristics such as a large surface area, high surface activity, high catalytic efficiency, strong adsorbing ability, high bioavailability and low toxicity. It is also, Selenium concentration of whole eggs, yolks and albumins higher in selenomethionin-fed laying hen than in sodium selenite. Also, research has shown that the addition of organic selenium to the diet of commercial laying hens significantly increases the selenium concentration in egg yolk and egg albumins. Since there is little information about the antioxidant effects of selenium nanoparticles on antioxidant status in laying hens, the main goal of this study was to compare the antioxidant effects of nano-selenium in laying hens and the oxidative stability of eggs during storage in the warehouse was. Materials and Methods This experiment was carried out in a completely randomized design with 4 treatments, 4 replicates and 10 birds per experimental unit in a total of 160 laying hens of HY-Line W36 from 30 …
