- ÍtemAcceso AbiertoEvaluación de la Vitamina K y Coenzima Q10 en la refrigeración de semen equino(Universidad Católica de Cuenca., 2024) Cabrera Saldaña, Juan Carlos; Argudo Garzón, Daniel; 0105709489This study highlights how vitamin K and coenzyme Q10 may influence the quality of cryopreserved sperm in horses, whose viability tends to be lower compared to other species, thereby limiting advancements in reproductive biotechnology. Beginning of the form. Therefore, the justification for this study stems from the need to overcome the limitations of equine fertility. To assess equine semen, the dependent variables included motility and sperm abnormalities, while the independent variables were the presence of vitamin K, coenzyme Q10, and a control group without these supplements. The viability of vitamin K (T2) had a slightly higher mean of 60.38 ± 2.08. Regarding membrane functionality, there were differences between treatments, with T2 (83.04 + 11.03) standing out compared to T1 and T3. On the other hand, after 48 hours of freezing, there is a consistent decrease in sperm values compared to the first 24 hours. Variations in mitochondrial activity were observed between the treatments, indicating a deterioration in sperm quality. The results indicate that sperm can be frozen for 24 hours without significant changes, but extended storage is not recommended. Keywords: Fertility, Coenzyme Q10, Vitamin K, Semen
