The kinetics of goat sperm is negatively affected after freezing in an extender including zinc oxide nanoparticles.
Background: Nanotechnology can benefit livestock industries, especially through postharvest semen manipulation. Zinc oxide nanoparticles (Np-ZnO) are potentially an example.
Objective: To investigate how the addition of zinc oxide nanoparticles (Np-ZnO) affected the characteristics of post-thawed goat semen.
Materials and methods: Seminal pools from four Saanen bucks were used. Semen was diluted in Tris-egg yolk extender, supplemented with Np-ZnO (0, 50, 100 or 200 ug/mL), frozen and stored in liquid nitrogen (-196 degree C), and thawed in a water bath (37 degree C / 30 s). Semen samples were evaluated for sperm kinetics by computer-assisted sperm analysis (CASA), and assessed for other functional properties by epifluorescence microscopy, such as plasma membrane integrity (PMi), acrosomal membrane integrity (ACi) and mitochondrial membrane potential (MMP).
Results: For total motility (TM), the group treated with 200 ug/mL Np-ZnO was superior to the control. In straight-line velocity (VSL), the control was better than the group containing 200 ug/mL of Np-ZnO. For average path velocity (VAP), the control was higher than with 100 ug/mL Np-ZnO. For linearity (LIN), the control was higher than with 200 μg/mL Np-ZnO. In straightness (STR), the control and 100 μg/mL Np-ZnO were higher than with 200 ug/mL Np-ZnO. In wobble (WOB), the control was better than the 50 μg/mL Np-ZnO treatment. In PMi, ACi and MMP no significant differences were found.
Conclusion: The addition of Np-ZnO (200 ug/mL) to the goat semen freezing extender improved the total motility of cells, whilst negatively affecting sperm kinetics. https://doi.org/10.54680/fr24210110512.
期刊介绍：
A bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation
The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
