Two hundred and forty 10-wk-oldJapanese quails were randomly assigned to four dietary groups, each one four timesreplicated with fifteen quails per dietary groups. Control group fed the basal diet; othergroups were fed basal diet supplemented with 0, 0.5, 1.0 and 1.5% licorice root powder.There were no significant differences in terms of final live weight, feed intake, feedconversion ratio, egg weight, serum cholesterol, triglyceride and High-DensityLipoprotein (HDL) concentration between treatment groups. Egg production was higherin control group and 0.5% licorice root powder supplemented groups. 1.0% licorice rootpowder supplemented group had lower egg production rate. Licorice root powdersupplementation decreased Low Density Lipoprotein (LDL) concentration and increasedglucose concentration significantly. Licorice root powder supplementation increased totalantioxidant status (TAS) and reduced total oxidant status (TOS) and oxidative stressindex (OSI). It was concluded from this study that supplementation of licorice rootpowder at the level of 0.5, 1.0 and 1.5% to the feed of laying quails had no adverseeffects on performance. Licorice root powder supplementation can be used to reducecholesterol level and increase antioxidant status in quails.en10.24925/turjaf.v6i9.1290-1296.2124info:eu-repo/semantics/openAccessArticle6912901296329185
