Effects of chromium nano particles (NanoCr) on performance and meat quality of Japanese quail under physiological stress was determined by using 360 birds in a completely randomized design with six treatments, four replicates and 15 birds per each, during 17- 35 d of age. The tratments were negative control (non-stressed), and five groups under physiological stress which fed on diets supplemented with different levels of NanoCr (0, 200, 400, 800 and 1200 µgkg-1). Dexamethasone (0.6 mgkg-1 BW) was added to diet for induction of physiological stress. Physiological stress reduced feed intake and growth, whereas increased feed conversion ratio (FCR) and thigh and breast muscles malondialdehyde (MDA) concentration (P<0.05). Stressed birds were fed on diets containing increased levels of NanoCr linearly improved weight gain (P< 0.02), and decreaced FCR (P< 0.05), MDA levels in breast (P< 0.04), and thigh muscles (P< 0.006). The results showed that supplementation of diet with NanoCr can alleviate the negative effects of physiological stress on performance and meat quality of quails.
