Ítem Acceso Abierto Evaluación de la coenzima Q10 y la vitamina K en la congelación de semen equino(Universidad Católica de Cuenca., 2024) Pilco Gavilanez, Danny Javier; Argudo Garzón, Daniel; 0606175586Frozen equine semen shows lower viability than other species, mainly due to specific equine factors or individual variability per breeder. Additionally, breeding males are selected for their performance in various equestrian events rather than their reproductive capacity, creating a challenge in preserving and enhancing the animal's genes. This study is justified by estimating that adding coenzyme Q10 and vitamin K to frozen spermatozoa has a beneficial effect on their motility and other seminal quality parameters. For this purpose, variables such as motility, mobility, abnormalities, membrane functionality, and mitochondrial integrity were considered. Independent variables such as fresh sperm, coenzyme Q10 (treatment), and vitamin K (treatment) were used compared to a control group. The results were significant for sperm motility, with 92.20 ± 1.82 for the third horse. Regarding sperm concentration, a peak was shown in equine two with 115.60 ± 17.07, contributing to a total of approximately 1398.19 x 10⁶ ejaculated sperm. In addition, the data suggested no significant variation in the application of coenzyme Q10 and vitamin K regarding mitochondrial motility and mitochondrial activity. This led to the conclusion that adding coenzyme Q10 and vitamin K to sperm does not significantly effect quality parameters such as motility and mitochondrial integrity. Only in certain situations could this improve the quality of equine semen by cryopreservation. Keywords Equine., semen., freezing., coenzyme Q10., vitamin K.
