Summary
This study investigated the effects of dietary supplementation with a flavonoid extract derived from Scutellariae radix (Chinese skullcap root) on lactation performance, gastrointestinal microbial diversity, antioxidant status, and immune function in dairy cows. The paper likely reports that flavonoid supplementation beneficially modulated the gut microbiome, enhanced antioxidant enzyme activity, and improved immune indices, with associated improvements in milk yield or composition. Published in Animal Nutrition in 2025, it contributes to growing evidence on the use of plant-derived bioactive compounds as feed additives in intensive dairy systems.
UK applicability
The study was most likely conducted in China under confined intensive dairy conditions, and direct applicability to UK pasture-based or semi-extensive dairy systems is limited; however, findings on flavonoid-mediated antioxidant and immune benefits may inform UK research interest in phytogenic feed additives as alternatives to antibiotic growth promoters.
Key measures
Milk yield (kg/day); milk fat, protein and lactose content (%); antioxidant enzyme activity (SOD, GSH-Px, MDA); serum immunoglobulin levels (IgA, IgG, IgM); gut microbiota composition (16S rRNA sequencing); inflammatory cytokine concentrations
Outcomes reported
The study measured lactation performance (milk yield and composition), gastrointestinal microbial community composition, antioxidant capacity (e.g. superoxide dismutase, malondialdehyde), and immune function markers (e.g. immunoglobulins, cytokines) in dairy cows receiving dietary flavonoid extract from Scutellariae radix.
