Effects of quercetin and genistein on egg quality, lipid profiles and immunity in laying hens.

This study confirmed that supplemental quercetin and genistein, either separately or in combination, can enhance eggshell thickness, lipid profiles, and immune function in aging hens. Moreover, both quercetin alone and quercetin + genistein exhibited similar abilities to lower lipid levels and improve immune function. This article is protected by copyright. All rights reserved.
