Abstract: The current study aimed to investigate the effects of dietary Galla Chinensis tannin (GCT) supplementation on antioxidant capacity and gut microbiota composition in broilers. Two hundred eighty-eight Arbor Acres broiler chicks were divided into the CON group and the GCT group; each treatment group contained 6 replicates with 24 broiler chicks per replicate for a period of 42 days, and were fed either a basal diet or the basal diet supplemented with 300 mg/kg GCT. Results revealed that GCT supplementation significantly increased glutathione peroxidase (GSH-Px) activity ( p < 0.05) and significantly decreased malondialdehyde (MAD) concentrations in serum ( p < 0.05) and significantly increased GSH-Px and catalase (CAT) ( p < 0.05) and significantly decreased MDA concentrations in the small intestine. In addition, GCT significantly up-regulated ( p < 0.05) the gene expressions of nuclear factor erythroid 2-related factor 2 ( Nrf2 ), heme-oxygenase 1 ( HO-1 ), catalase ( CAT ), glutathione peroxidase-1 ( GPX1 ), and NAD(P)H quinone oxidoreductase 1( NQO1 ). High-throughput sequencing results showed that GCT supplementation significantly increased abundances of Faecalibacterium and Megamonas ( p < 0.05). These findings will contribute to our understanding of the effects of dietary Galla Chinensis tannin supplementation on antioxidant capacity and intestinal microbiota composition in broilers.
