Abstract
In the present study, the effect of ether extract of propolis on the semen characteristics of Zel's ram under short and long-term preservation was investigated. The experimental groups comprised different concentrations of ether extract (0, 0.25, 0.5, and 1 mg/mL) and dimethyl sulfoxide (DMSO). The samples were evaluated at 0, 24, 48, and 72 hours after storage at 4 °C and following the freeze-thawing process. During the cold storage, sperm quality traits motility, viability, membrane integrity, mitochondrial activity, malondialdehyde concentration (MDA), and morphology increased significantly (P<0.05) at concentrations of 0.25 and 0.5 mg/mL ether extract in comparison with the control group. Our results revealed that the total motility, viability, and membrane integrity in the concentration of 0.5 mg/mL ether extract were higher than the control group (P<0.05) at 4 °C. Also, motility, viability and malondialdehyde concentration (MDA) were higher in concentrations of 0.25 mg/mL ether extract than in the control group in the freeze-thawing process. Mitochondrial activity and morphology of spermatozoid at 0.25 and 0.5 mg/mL ether extract were higher than the control group (P<0.05) in storage at 4 °C and freeze-thawing process. Results showed adding ether extract at the concentrations of 0.25 and 0.5 mg/mL to the semen extender improved the quality of spermatozoid in the Zel breed sheep.
