Hormonal Management for the Induction of Luteolysis and Ovulation in Andalusian Jennies: Effect on Reproductive Performance, Embryo Quality and Recovery Rate
(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 ...
Medidas de circunferencia escrotal y rubor inguinal sexual en el macho cabrío de raza florida
(Universidad de Córdoba, Servicio de Publicaciones, 2002)
Escrotal circumference (CE) by orquimetry and skin flush sexual (SFS) by observation in the inguino-escrotal skin in four Florida male goats were studied for 14 months. Seasonal variation was observed in CE, that was minor ...
DNA fragmentation of equine cumulus cells from Cumulus-Oocyte complexes submitted to vitrification and its relationship to the developmental competence of the oocyte
(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 ...
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 ...
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 ...
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 ...
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 ...
Antimicrobial activity of silver-carbon nanoparticles on the bacterial flora of bull semen
(Elsevier, 2021)
The spermicidal effects of silver nanoparticles (AgNPs) hinder its application in the field of artificial insemination. In this study, silver-carbon NPs (Ag@C NPs) was synthesized and applied as an alternative antibiotic ...
Cryopreservation of donkey embryos by the cryotop method: Effect of developmental stage, embryo quality, diameter and age of embryos
(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 ...
One-step warming does not affect the in vitro viability and cryosurvival of cryotop-vitrified donkey embryos
(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 ...
