<br/><br/> Nanotechnology has the potential to revolutionize in poultry industry with new tools for the molecular treatment of diseases <br/>and enhancing the ability of animal to absorb nutrients and therefore improving productive performance response of poultry. <br/>The essential trace elements play important roles such as nutrients metabolism, antioxidant, component of numerous metalloenzymes <br/>and protein. Nanoparticles zinc oxide (Nano-ZnO) is the specially prepared mineral salt having particle size of 1 to 100 nm. <br/>It promotes growth can act as antibacterial agent, modulates the immunity and production of laying hens. Using of Nano-ZnO in <br/>laying hen's nutrition as nanoparticle size will help and improve the egg production sector. Therefore, the purpose of this study <br/>is to give an overview on the potential of Nano-ZnO as feed additives in laying hen diets, in order to explore the mechanism of <br/>the effects of Nano-ZnO supplementation on laying hen productive performance and to observe their influence on feed intake, <br/>ammonia emissions, digestibility, egg production, and egg quality.<br/>Key words: Egg production, Egg quality, Laying hens, Mode of action, Nanotechnology<br/>
