Effect of nanoparticles of silver on redox status and the accumulation of Ag in chicken tissues.

Background: The aim of the study was to verify the hypothesis that there are doses of silver nanoparticles (Ag-NPs) that improve antioxidant defence in chickens without compromising their growth performance and health.

Results: The results of our study suggest that, irrespective of the concentration, the administration of Ag-NPs (5 nm) at a dose not exceeding 54 mg/bird has no negative effect on the growth performance of chickens. The administration of Ag-NPs (5 nm) in the amount of 2.
