A study was conducted to evaluate the antioxidant effects of selenium nanoparticles and sodium selenite on the antioxidant status, enzymatic activity and plasma lipid parameters of Pullet Chickswith 1050 birds in 7 treatments for 6 weeks. The treatments included three levels of 0.15, 0.3 and 0.6 (ppm) sodium selenite and nano selenium. The antioxidant indices measured in the heart, liver and plasma include glutathione peroxidase (GPx), malondialdehyde (MDA) and total antioxidant capacity (TAS). Activity of alanine aminotransferase (ALT) enzymes, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were measured and lipid parameters including total triglyceride, total cholesterol and plasma LDL were determined. The results showed that sodium selenite and selenium nanoparticles significantly increased the activity of glutathione peroxidase and reduced levels of malondialdehyde in the plasma, heart and liver. The highest antioxidant effect was related to 0.6 ppm sodium selenium and 0.3 ppm selenium nanoparticles. There was no significant effect on total antioxidant capacity of plasma, heart and liver in experimental group (P<0.05) .There was no significant effect of experimental treatments on plasma enzyme activity (P<0.05). Sodium selenite and selenium nanoparticles at levels of 0.3 and 0.6 ppm significantly decreased triglyceride, cholesterol and LDL in the plasma of birds (P<0.05). Conclusion 0.3 ppm of selenium nanoparticles and 0.6 ppm of Sodium selenitecan be successfully used to improve the antioxidant status and reduce plasma bad fats.
