Abstract The objective of this experiment was to study the effect of inorganic, organic and elemental nano-selenium on growth performance, Se concentration and antioxidant status in growing male goats. A total of 40 weaned Taihang black goats were randomly divided into four equal groups, given the basal diet either unsupplemented (CTRL only received 0.03 mg/kg Se background) or supplemented with 0.3 mg/kg Se as sodium selenite (SS), Se-yeast (SY) or elemental nano-selenium (NS) for a 90 days experiment (from weaning to maturity). Average initial and finial body weight (BW) and average daily gain (ADG) were recorded. Serum and whole blood were collected for serum glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) activity and Se content analysis. At the end of the feeding trail five bucks in each group were killed and samples of heart, liver, spleen, lung, kidney, muscle and testis were collected for Se determination. The result showed that the final BW was increased (P
