N2  - Nanotechnology has the potential to revolutionize in poultry industry with new tools for the molecular treatment of diseases 
and enhancing the ability of animal to absorb nutrients and therefore improving productive performance response of poultry. 
The essential trace elements play important roles such as nutrients metabolism, antioxidant, component of numerous metalloenzymes 
and protein. Nanoparticles zinc oxide (Nano-ZnO) is the specially prepared mineral salt having particle size of 1 to 100 nm. 
It promotes growth can act as antibacterial agent, modulates the immunity and production of laying hens. Using of Nano-ZnO in 
laying hen's nutrition as nanoparticle size will help and improve the egg production sector. Therefore, the purpose of this study 
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 
the effects of Nano-ZnO supplementation on laying hen productive performance and to observe their influence on feed intake, 
ammonia emissions, digestibility, egg production, and egg quality.
Key words: Egg production, Egg quality, Laying hens, Mode of action, Nanotechnology
