The Impact of Organic Selenium Supplementation on Rooster Semen Quality in Liquid Condition

This research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1, 0.2 and 0.3 mg/kg) on reproductive traits of rooster. semen was collected using abdominal massage and samples were mixed together. sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. this experiment was carried out based on a completely randomized design. results showed that the organic selenium supplementation had significant effects on sperm motility and viability in liquid condition (p<0.05). the use of organic selenium at the level of 0.3 mg/kg significantly improved sperm motility and viability at storage times of 4, 8, 12 and 24 h in comparison with the control group. birds were fed with organic selenium had lower abnormal sperm percentage in comparison with the control group (p<0.05). supplementing diets with 0.1, 0.2 and 0.3 mg/kg organic selenium had no effect on semen concentration, ph and volume (p>0.05). in conclusion, the use of organic selenium supplementation (0.3 mg/kg) in diet of rooster could be recommended to improve semen quality.
