Dietary quercetagetin attenuates H₂O₂-induced oxidative damage and preserves meat quality in broilers by modulating redox status and Nrf2/ferroptosis signaling pathway.

ABSTRACT: In modern poultry production, oxidative stress has emerged as a pivotal factor compromising the health status and overall performance of broiler. The aim of this study was to investigate the effects of dietary quercetagetin (QG) supplementation on hydrogen peroxide (H₂O₂)-induced oxidative damage in breast muscle of broilers, focusing on growth performance, meat quality, and antioxidant function, and elucidating the underlying mechanisms. Two hundred and forty one-day-old Cobb broilers were randomly divided into three treatment groups: the control group, the H₂O₂ group and the H₂O₂ + QG group. The control and H₂O₂ groups were fed a basal diet, and the QG group was fed a basal diet supplemented with 100
