An experiment was designed to investigate the effects of supplementing inorganic, organic and nano selenium on growth performance and antioxidant status of Giriraja chicken reared in deep litter system up to eight weeks of age. A total of 384 day old straight run chicks were equally divided into eight treatment groups with four replicates each. Control group (T1) was fed with basal broiler diet (NRC, 1994) without added selenium supplementation in premix. Experimental groups T2 and T3 were given basal diet supplemented with Sodium selenite to contain selenium concentration of 150 ppb and 300 ppb, respectively in the experimental feed. Selenium concentration of 150 ppb and 300 ppb using selenium yeast is added to basal diet to form experimental diet for T4 and T5. Experimental groups T6, T7 and T8 were fed on basal diet containing 50ppb, 150ppb and 300ppb selenium supplemented with nano selenium. Standard management and vaccination procedures were followed throughout the study. Weekly cumulative body weight, feed intake and overall cumulative FCR were similar between treatment groups. Antioxidant enzymes GPx, SOD level were increased in liver with selenium supplementation than the control group while catalase activity was improved by 300 ppb selenium supplementation irrespective of source. TBARS value recorded was significantly reduced in 150 ppb and 300 ppb organic and nano selenium supplemented groups.
