This study was conducted to investigate the effect of dietary domestic Skullcap (Scutellaria baicalensis) extracts (SCE) on laying performance and egg quality in laying hens. There were no significant differences in feed intake, egg production, or relative liver and spleen weights. The egg weights in groups fed diets containing SCE were significantly increased as compared with the control. The number of cecal total microbes in the group fed a diet containing 0.5% SCE was significantly reduced as compared with other groups. The malondialdehyde contents in stored eggs were significantly lowered by feeding SCE. The Haugh unit in the groups fed diets containing SCE tended to be increased after 2 weeks storage, but not significantly. This result indicated that dietary domestic SCE may delay lipid oxidation in eggs when added to laying hen diets.
