Abstract

Three hundred and sixty unsexed day-old chicks of Indian River (IR) broiler chicks were used to study the effect of using different types and levels of nanoparticles (silver and graphene) in broiler diets on performance, and carcass characteristics. This experiment contained 9 treatments and 40 chicks for each treatment. The experiment lasted from 1 to 35 days of age and contained three dietary phases (starter, grower and finisher) contained 2.5, 5.0, 7.5, and 10.0 ppm/kg of both silver (SNaPs) and graphene (GNaPs) nanoparticles, in addition to a control (basal diets) through the three stages. The results showed that:

Productive performance including LBW, BWG, FI, PI and EPEF differed significantly between treatments related to the different levels of nanoparticles but were not affected by the different types of nanoparticles overall period. Also FCR was not differed significantly, affected by either type or level of nanoparticles during the overall period.
All carcass traits and total digestive tract and ceca length were not significantly affected by the treatments except for liver percentage which increased significantly with higher nanoparticles levels in diets.T                                    There weren't significant differences between the two types of nanoparticles (silver and graphene) as feed additives on productive performance and carcass characteristics. The different levels of nanoparticles decreased LBW and BWG and increased liver percentage compered to control.
