This study aimed to assess levels of silver nanoparticle residues in eggshells and tissues as well as the levels of selected biochemical parameters and oxidative stress indices in chickens hatched from nanosilver disinfected eggs. The samples included 40 Greenleg Partridge chicks allocated into two groups. The experimental group (group D) consisted of chickens hatched from eggs disinfected with a nanosilver preparation prior to incubation, while the control group (group C) included chickens whose eggs were exposed to UV radiation for disinfection. The eggshells and kidney sections obtained from group D chickens showed a significantly higher silver level compared to group C. For the biochemical parameters, only the uric acid content was higher in group D compared to group C. Analysis of the antioxidative stress biomarkers (superoxide dismutase and catalase), showed a significant increase in group D in relation to group C.
