Characterisation of the oral glucose and sugar tolerance tests and the enteroinsular axis response in healthy adult donkeys
(Wiley, 2022)Background Insulin dysregulation (ID) is diagnosed in horses and ponies using oral glucose (OGTT) and oral sugar (OSTT) tolerance tests. The enteroinsular axis plays a major role in postprandial glucose disposal and ... -
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
(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 ... -
Efecto de la selección de espermatozoides mediante centrifugación coloidal sobre la calidad de las dosis de semen de asno refrigeradas y congeladas
(Universidad de Córdoba, UCOPress, 2016)A día de hoy, los asnos han perdido su rol tradicional, lo que ha resultado en la inclusión de las razas de asnos ibéricas en el catálogo de especies amenazadas de la Organización de las Naciones Unidas para la Alimentación ... -
Evaluation of the combined glucose-insulin and intravenous glucose tolerance tests for insulin dysregulation diagnosis in donkeys
(Wiley, 2021)Background. Insulin dysregulation (ID) and donkey metabolic syndrome (DMS) are common in this species. Contrary to horses, diagnostic guidelines compiling insulin cut-offs values and dynamic testing interpretations have ... -
Factors Affecting Embryo Recovery Rate, Quality, and Diameter in Andalusian Donkey Jennies
(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 ... -
Optimization of donkey sperm freezing and vitrification
(Universidad de Córdoba, UCOPress, 2021)Assisted reproductive technologies such as artificial insemination (AI) and semen cryopreservation are important tools to maintain the genetic diversity and preserve endangered species, including most of the European donkey ... -
Structural organization of genetic diversity and ethofunctional characterization in the Andalusian donkey breed
(Universidad de Córdoba, UCOPress, 2019)Tools allowing to understand the evolution of donkey populations in time, the future trends that these populations describe, and the factors conditioning such trends, become invaluably critical when aiming at preserving ... -
The cryoprotective effect of Ficoll 70 on the post-warming survival and quality of Cryotop-vitrified donkey embryos
(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 ... -
Vitrification of Donkey Sperm: Is It Better Using Permeable Cryoprotectants?
(MDPI, 2020)Vitrification by direct exposure of sperm to liquid nitrogen is increasing in popularity as an alternative to conventional freezing. In this study, the effect of permeable cryoprotectant agents for donkey sperm vitrification ...
