| Abstract: | A new device for storage and shipping of cell cultures – the Petaka G3 cell management device – was tested for its applicability for cooled‐storage of equine semen. Semen from three stallions was processed with EquiPro extender either without antibiotics (three ejaculates per stallion) or with gentamicin (250 mg / l; three ejaculates per stallion). Semen was either stored at five (anaerobic conditions) or 15°C (aerobic conditions) in syringes or cell culture devices. Total and progressive motility, as well as membrane integrity of spermatozoa, were evaluated from days 1 to 7 after collection with computer‐assisted semen analysis. In experiment 1 (extender without antibiotics), total motility, progressive motility and viability of spermatozoa significantly decreased over time (p < 0.05). The decrease was significantly faster at 15°C than at 5°C (p < 0.05). In the presence of gentamicin (experiment 2), this difference was no longer present. It can be concluded that cooled‐storage of equine semen in sophisticated devices for cell culture is not advantageous to syringes for successful maintenance of semen longevity. |
