Fermented distiller's grains improve broiler immunity and antioxidant capacity by modulating cecal microbiota and cecal/plasma metabolomes.

ABSTRACT: Fermented distiller's grains (FDG) are rich in nutrients and have high feed utilisation value, but research in broiler feeding is limited. In this experiment, 216 male yellow-feathered broilers (30-day-old, 584.0 ± 3.85 g) were randomly divided into three groups, with six replicates per group and 12 broilers per replicate. The diet treatments were the control group, the 5% FDG group and the 10% FDG group (containing 0%, 5% and 10% FDG to partially replace the concentrates, respectively). The results showed that, compared with the control group, the 5% FDG and 10% FDG groups significantly increased the levels of serum immune index (IgA and IgG), antioxidant index (GSH-Px, SOD and CAT), serum biochemical index (IGF-1), and significantly decreased serum antioxidant index (MDA) of broilers. 16
