    • Abstract
    The present study aimed to investigate the effect of rearing broiler chickens under different monochromatic LED light color on their growth performance, fear responses and physiological responses. One hundred and thirty five unsexed day-old avian 48 chicks were randomly allocated into three light treatment (n=45 bird) each treatment 3 replicates (n=15 bird) treatments were white light, green light, and blue light.The obtained results demonstrated that, broilers reared under blue and green respectively showed higher body weight, weight gain, feed intake, eviscerated carcass weight, carcass percent, hemoglobin, red blood cells, packed cell volume, total leucocytes count, lymphocytes, total protein, albumin, globulin and lower feed conversion ratio, bursa, liver, spleen relative weight, heterophils, heterophils: lymphocytes ratio, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase compared with white light. Moreover, blue and green lights showed short tonic immobility duration and high levels of exploration in the open field test. In conclusion, rearing broilers under blue and green light for 23 h per day improve growth performance, physiological responses, welfare, reduce stress and fear reaction.

    Key words: Key words: behaviour, broilers, fear reaction, monochromatic LED light, performance.
