Abstract
To improve the semen production, the selenium(Se) and vitamin E(Vit. E) were administrated into Hanwoo young sire for intensification an antioxidant system and the taurine were supplemented into semen extender for improving the semen characteristics. The 16 heads ranging from twenty to thirty two months of age were randomly assigned to control group, Se-admistrated group(Se-group), Vit. E-administrated group(Vit. E-Group) and Se and Vit. E administrated group(Se and Vit. E-group). Se and Vit. E dministrated 3 times every 30 days by intramuscular injection. The administration of Se, Vit. E, and Se and Vit. E didn't affect on semen volume, sperm concentration, and total sperm number among all groups(p>0.05). Adiministration of Se improved sperm motility and viability. Motility of Se-group and control were 26.01% and 19.20%, respectively(p<0.05). Viability of Se-group(47.07%) was higher than control group(35.73%), Vit. E group(36.55%)(p<0.05). The administration of Se and Vit. E didn't affect sperm capacitation and acrosome reaction. The 100mM taurine supplement into semen extender increased the motility of frozen/thawed semen in the Vit. E-group(p<0.05) and had a beneficial effects on decreasing abnormality of frozen/thawed semen in all groups(p<0.05). These results indicate that Se administration improve sperm motility and viability, and the taurine supplement into semen extender decrease abnormality in Hanwoo young sire.
