Methods: An in vivo feeding experiment was conducted in 150 broiler chicks. three replicates of 10 birds were maintained for each treatment with various levels of selenium nanoparticles (0.075, 0.1125. 0.1875 and 0.225 mg/kg ) along with selenium coarse particles (0.15 mg/kg) as control group. The serum samples obtained from different treatments were subjected to analysis of antioxidant enzymes. The data obtained were analysed with ANalysis Of VAriance (ANOVA). Findings: Birds supplemented with 0.1875 mg/kg selenium nano-particles showed a significant (p < 0.05), increase in serum superoxide dismutase activity and glutathione peroxidase activity and decrease in malondialdehyde concentration.enVeterinary ScienceArticle
