The current study was conducted to examine the influences of Sargassam cristafolium, Gracilaria pulvinata, Rhus coriaria, and Punica granatum peel dried powder in two levels (10 and 20gr/kg) of dietary on productive performance and some egg quality characteristics of laying Japanese quail. A total of 675 (49 days old) Japanese quail were randomly distributed into nine groups with three replicates of 25 birds in each. Results showed that egg weight, shell weight, albumen weight and shell thickness were not influenced by treatments. The effects of medicinal plants on weekly egg production differ depending on the dietary medicinal plant type and dosage. Moreover, the birds fed diet supplemented with Sargassum cristaefolium at 10g/kg had greater weekly egg production compared to others. Haugh unit was reduced by diet supplemented with R. coriaria. Diet supplemented with S. cristaefolium at 20 g/kg increased yolk weight. Furthermore, greater albumen protein and thiobarbituric acid content of the tenth day's eggs (TBAd10) were perceived in birds fed diet supplemented with G. pulvinata. In present study, the lowest levels of cholesterol (9.66 mg/g) was determined in the egg yolk of groups R. coriaria and G. pulvinata, and the control group showed to have the most amounts (12.00 mg/g). Based on obtained data, addition of 0.5% and 2% of S. cristafolium, G. pulvinata, R. coriaria, and P. granatum peel to the diet lead to be progress in egg production rate, enhanced the egg quality and egg biochemical properties in Japanese quail.
