[email protected] This research was conducted to determine the effects of phytase or dicalcium phosphate (DCP) supplementation on performance, egg quality, serum total protein (TP), calcium (Ca) and phosphorus (P) level, tibia ash, Ca and P concentration, excreta ash, Ca and P level of barley based protein deficient quail diets. A total of 270, 10 wk old quails were used. Diets were insufficient in available P and had a different crude protein (CP) level (16, 18, 20%). It was made phytase or DCP supplementation on each protein level. At the end of the study, quails had similar body weight, body weight change and feed conversion ratio although feed consumption was affected by the CP level (P
