ABSTRACT: Environmental pollution poses a significant challenge to the poultry industry, leading to substantial losses and adverse effects on the health, production, and performance of avian species. In recent years, there has been growing interest in exploring natural compounds with potential protective effects against cadmium (Cd)-induced toxicity. Luteolin (LUT), a flavonoid found in various plants, has been studied for its antioxidant, anti-inflammatory, and cytoprotective properties. In this study, Su green shell grass chickens were divided into 4 groups: control, LUT (150 mg LUT), Cd (100 mg CdCl2), and Cd + LUT (100 mg CdCl2 + 150 mg LUT) groups for 1 month, respectively. The present study revealed that LUT maintained the morphology and functional activity of the liver and intestine. LUT alleviated Cd-induced impairment in the liver and intestinal biochemical indicators, suppressed Cd-induced liver fibrosis, mitigated liver and intestinal tissue damage. Additionally, LUT reduced oxidative stress and regulated the Cd-induced impairment in trace elements of the liver and intestine. Furthermore, LUT reduced Cd-induced liver inflammation, restored Cd-induced intestinal barrier function, and normalized Cd-induced serum proteins, including changes in the content of glutamyltranspeptidase. Moreover, LUT maintained Cd-induced disruption of gut microbiota and alleviated bacterial dysbiosis. Overall, these findings suggest that LUT holds promise as a potential therapeutic agent for mitigating the adverse effects of Cd-induced toxicity in poultry, by preserving liver and intestinal health, reducing oxidative stress, inflammation, and restoring gut microbiota balance.
