The objective of this experiment was to study the effects of dietary nano-selenium supplementation on the glutathione peroxidase activity and sperm quality and quantity parameters of Arabian rams. In this experiment, twelve Arabian rams with an average weight of 73±3 kg and age of two to four years were used. Animals were divided into three groups: the control group (without -nano Selenium) and two experimental groups that received 0.4 and 0.8 mg nano-selenium per kg dry matter, respectively. The results showed that significant increase in semen selenium concentration and semen glutathione peroxidase activity in group 0.8 mg nano-selenium compared with the control group (P<0.05), but there was no significant difference between 0.4 mg nano-selenium per kg supplementation and control group. The volume of ejaculate, sperm motility and viability increased in treatments compared with the control. Spermatozoa concentration was increased in group 0.4 mg nano-selenium per kg, but it was decreased in Group 0.8 mg nano-selenium per kg. The percentage of sperm abnormality significantly increased in control compared with experimental groups. According to the results of this research, supplementation of 0.4 mg Nano-selenium per kg dry matter in the diet, increased the glutathione peroxidase activity in semen and improve the quality and quantity characteristics of sperm.
