The present study was conducted to examine the protective role of arginine and trehalose on post-thaw bull sperm and oxidative stress parameters. Five ejaculates for each bull were used in the study. Each ejaculate, split into three equal aliquots and diluted at 37 °C with base extenders containing 2 mM arginine, 25 mM trehalose and no antioxidant (control) was cooled to 5 °C and then frozen. Frozen straws were thawed in a water bath for evaluation. Supplementation of the semen extender with arginine decreased the percentages of post-thawed subjective motility (29 ± 8.21%), CASA motility (12.2 ± 5.69%) and progressive motility (3.52 ± 2.13%), compared with the controls (43 ± 2.73%, 55.4 ± 6.78% and 33.48 ± 4.14%, respectively, P < 0.05). Supplementation of the semen extender with trehalose produced a higher mitochondrial activity and sperm viability (36.3 ± 3.99% and 44.1 ± 2.18%) compared with the control (13 ± 8.15 and 31.7 ± 3.94%, respectively, P < 0.05). It was established that trehalose (95.1%) and arginine (92.8%) protect DNA integrity compared to the control (90.4%) (P < 0.05). Trehalose supplementation in semen extenders provided great benefit in terms of viability, mitochondrial activity, and intact sperm DNA on frozen-thawed bull sperm.
