In the present research the effect of different levels of chromium picolinate on performance, egg quality and some blood metabolite of laying Japanese quail at late phase of production were evaluated. Six hundered quails were allocated to 5 treatments with 4 replicates of 30 birds per replicates in a completely randomized design arrangement with repeated measurement. The experimental treatments  was consist 1) basal diet, 2)basal diet + 0.4 mg/kg chromium picolinate, 3) basal diet + 0.8 mg/kg chromium picolinate 4) basal diet + 1.2 mg/kg chromium picolinate 5) basal diet + 1.6 mg/kg chromium picolinate. Performance and egg quality traits measured four times along the experiment and analysed by repeated measurement proc. Result of this experiment showed that egg production and feed conversion ratio was affected by different experimental treatment, and quails with 1.4 mg/kg dietary chromium showed optimum performance. Dietary chromium had significant (P<0.05) effect on egg weight along the experiment and time affect the egg weight significantly. Dietary chromium had no significant (P>0.05) effect on egg quality traits such as yolk, white, shell weight, Haugh unit, shell tickness and shell weight. Serum total cholesterol, triglyceride, LDL, AST and AST was not affected by different chromium addition to basal diet. It can be concluded that inclusion of 1.4 and 1.6 mg/kg chromium to basal diet had some beneficial effect on egg production, feed conversion ratio and egg weight in laying Japanese quail.
