Abstract
To investigate the effects of supplementation of vitamin $B_{12}$ on bovine sperm post-thaw quality, vitamin $B_{12}$ was added at the concentrations of 1.25, 2.50, 3.75, and 5.00 mg/mL to bovine semen cryoprotective medium. The results indicated that the motility and VSL, VCL, STR, and VAP values of sperm supplemented with 2.50 mg/mL vitamin $B_{12}$ were significantly higher than those of other concentrations (P 0.05). The percentages of acrosome-intact and plasma membrane-intact spermatozoa were significantly improved (P < 0.05) by supplementing with 2.50 mg/mL vitamin $B_{12}$ . With all parameters measured, the concentration of 2.50 mg/mL vitamin $B_{12}$ showed the best results on the quality of bovine semen in freezing-thawing. In conclusion, the addition of 2.50 mg/mL vitamin $B_{12}$ to the extender improved the bovine frozen semen quality.
