Characterization of the seminal bacterial microbiome of healthy, fertile stallions using next-generation sequencing
Quiñones-Pérez, Carlota; Hidalgo, Manuel; Ortiz, I.; Crespo Castejón, Francisco; Vega-Pla, J.L. (Colégio Brasileiro de Reprodução Animal, 2021)High-throughput sequencing studies have shown the important role microbial communities play in the male reproductive tract, indicating differences in the semen microbial composition between fertile and infertile males. ... -
Cryopreservation of Andalusian donkey (Equus asinus) spermatozoa: Use of alternative energy sources in the freezing extender affects post-thaw sperm motility patterns but not DNA stability
Dorado, Jesús; Hidalgo, Manuel; Acha Valls, Daniel; Ortiz, I.; Bottrel, M.; Azcona, Florencia; Carrasco, J.J.; Gómez-Arrones, V.; Demyda-Peyrás, S. (Elsevier, 2019)The aim of this study was to compare the effect of three sugars and Equex paste in a freezing extender for donkey sperm cryopreservation. Ejaculates (n = 18) were collected from six Andalusian donkeys of proven fertility ... -
Cryopreservation of donkey embryos by the cryotop method: Effect of developmental stage, embryo quality, diameter and age of embryos
Bottrel, M.; Ortiz, I.; Pereira, Blasa; Díaz-Jiménez, María; Hidalgo, Manuel; Consuegra, César; Morató, R.; Mogas, T.; Dorado, Jesús (Elsevier, 2019)Cryopreservation of embryos has the potential to become a valuable tool for the conservation of endangered donkey breeds. However, there are several factors that can affect cryosurvival of embryos. This study evaluates the ... -
DNA fragmentation of equine cumulus cells from Cumulus-Oocyte complexes submitted to vitrification and its relationship to the developmental competence of the oocyte
Ortiz, I.; Dorado, Jesús; Pereira, Blasa; Díaz-Jiménez, María; Consuegra, César; Gosalvez, Jaime; Hidalgo, Manuel (Wiley, 2022)The objectives of this study were to evaluate the effect of vitrification on the DNA fragmentation rate of equine cumulus cells and to assess its relationship to oocyte in vitro maturation (IVM) after ... -
Effect of single layer centrifugation using Androcoll-E-Large on the sperm quality parameters of cooled-stored donkey semen doses
Ortiz, I.; Dorado, Jesús; Ramírez, L.; Morell, J.M.; Acha Valls, Daniel; Urbano, M.; Gálvez, M.J.; Carrasco, J.J.; Gómez-Arrones, V.; Calero-Carretero, R.; Hidalgo, Manuel (The Animal Consortium, 2013)The aim of this study was to determine the effect of single layer centrifugation (SLC) using Androcoll-E-Large on donkey sperm quality parameters after 24 h of cool-storage. Ejaculates were collected from Andalusian donkeys ... -
Factors Affecting Embryo Recovery Rate, Quality, and Diameter in Andalusian Donkey Jennies
Dorado, Jesús; Bottrel, M.; Ortiz, I.; Díaz-Jiménez, María; Pereira, Blasa; Consuegra, César; Carrasco, J.J.; Gómez-Arrones, V.; Domingo, A.; Hidalgo, Manuel (MDPI, 2020)Embryo transfer and the vitrification of embryos could be used for the conservation and recovery of endangered donkey breeds. It is important to develop techniques that optimize recovery rates and the cryotolerance of ... -
Hormonal Management for the Induction of Luteolysis and Ovulation in Andalusian Jennies: Effect on Reproductive Performance, Embryo Quality and Recovery Rate
Bottrel, M.; Ortiz, I.; Hidalgo, Manuel; Díaz-Jiménez, María; Pereira, Blasa; Consuegra, César; Samy Yousef, Mohamed; Dorado, Jesús (MDPI, 2022)Two prostanglandins (luprostiol, LUP, and dinoprost, DIN) and two ovulation-inducing agents (human Chorionic Gonadotropin, hCG, and deslorelin, DES) were evaluated for luteolysis and estrus induction, and for ovulation ... -
One-step warming does not affect the in vitro viability and cryosurvival of cryotop-vitrified donkey embryos
Bottrel, M.; Hidalgo, Manuel; Mogas, T.; Pereira, Blasa; Ortiz, I.; Díaz-Jiménez, María; Consuegra, César; Morató, R.; Dorado, Jesús (Elsevier, 2020)The objective of this study was to compare the effects of two warming protocols (three-step vs. one-step dilution) on embryo quality, post-warming embryo survival and embryo cell viability of donkey embryos vitrified by ... -
Sistemas de autoevaluación virtual en inglés para fomentar el plurilingüismo en la asignatura de Reproducción y Obstetricia
Hidalgo, Manuel; Ortiz, I.; Dorado, Jesús; Díaz-Jiménez, María; Consuegra, César; Pereira, Blasa (UCOPress, 2017)En el presente proyecto se han elaborado de videos demostrativos de diferentes aspectos prácticos de la asignatura Reproducción y Obstetricia (“training clips”) con audio en inglés que completan las presentaciones, facilitando ... -
The cryoprotective effect of Ficoll 70 on the post-warming survival and quality of Cryotop-vitrified donkey embryos
Bottrel, M.; Mogas, T.; Pereira, Blasa; Ortiz, I.; Díaz-Jiménez, María; Consuegra, César; Hidalgo, Manuel; Morató, R.; Dorado, Jesús (Elsevier, 2020)Many domestic donkey breeds are at risk of extinction, there is a critical urgency for genome resource banking. In the present study, we examined whether the use of Ficoll 70 added to the vitrification medium containing ... -
The Semen Microbiome and Semen Parameters in Healthy Stallions
Quiñones-Pérez, Carlota; Martínez, Amparo; Ortiz, I.; Crespo Castejón, Francisco; Vega-Pla, J.L. (MDPI, 2022)Despite the advances in reproductive technology, there is still a considerable number of low sperm quality cases in stallions. Recent studies in humans have detected several seminal microflora–spermatozoa associations ...
