Quercetin Dietary Supplementation Advances Growth Performance, Gut Microbiota, and Intestinal mRNA Expression Genes in Broiler Chickens

Quercetin was fed to groups of broiler chickens at concentrations of 200, 400, and 800 ppm, and a control group was supplemented with a basal diet. Results revealed that quercetin dietary supplementation numerically improved the growth performance traits and significantly increased (p < 0.05) the...

Description
Summary:Quercetin was fed to groups of broiler chickens at concentrations of 200, 400, and 800 ppm, and a control group was supplemented with a basal diet. Results revealed that quercetin dietary supplementation numerically improved the growth performance traits and significantly increased (p < 0.05) the European production efficiency factor (EPEF) in the 200 ppm group. The total coliforms and Clostridium perfringens were decreased (p < 0.05) in quercetin-supplemented groups. Conversely, Lactobacillus counts were increased (p < 0.05), due to improvement of the gut microbiota environment in quercetin-supplemented groups. Moreover, the mRNA expression of intestinal Cu/Zn-superoxide dismutase (SOD1), glutathione peroxidase (GSH-Px) and nutritional transporters, including glucose transporter 2 (GLUT2), peptide transporter 1 (PEPT1), and fatty acid synthase (FAS) genes, were significantly upregulated in quercetin-supplemented groups. Quercetin enhanced intestinal morphometry. We can suggest quercetin supplementation in broiler chickens by levels between 200 and 400 ppm to enhance their development and gut environment.
