Desmosterol Incorporation Into Ram Sperm Membrane Before Cryopreservation Improves in vitro and in vivo Fertility
(Frontiers Media, 2021-06)Pregnancy rates in ewes are markedly low after cervical insemination with frozen-thawed sperm. Sensitivity of ram sperm to freeze-thawing is related to the lipid composition of the membrane, particularly to its low sterol ... -
Efecto del método de colecta de semen y plasma seminal sobre la supervivencia posdescongelación de espermatozoides ovinos
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2012)Los objetivos del presente trabajo fueron determinar las diferencias en los eyaculados obtenidos con electroeyaculador (EE) y vagina artificial (VA) y evaluar el efecto del agregado de plasma seminal (PS) obtenido con EE ... -
Effect of Seminal Plasma on Post‐Thaw Quality and Functionality of Corriedale Ram Sperm Obtained by Electroejaculation and Artificial Vagina
(Wiley, 2015-06)We have already shown that seminal collection method affects seminal plasma composition and sperm quality in Corriedale rams. In this study, we evaluated the effect of seminal plasma collected by electroejaculation or ... -
Electroejaculation Increases Low Molecular Weight Proteins in Seminal Plasma Modifying Sperm Quality in Corriedale Rams
(Wiley, 2014-04)This study was conducted to evaluate the effect of seminal collection method (artificial vagina or electroejaculation) on the protein composition of seminal plasma and sperm quality parameters in Corriedale rams. To address ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
(Wiley, 2016-03)Two experiments were carried out to examine in vitro quality and in vivo fertility of rabbit semen diluted in ultra‐high temperature (UHT) skim milk. In the first experiment, pooled ejaculates of 10 adult rabbits were ... -
Mejoramiento cualitativo de espermatozoides ovinos criopreservados a partir de la utilización de moléculas diferenciales de plasma seminal obtenidas por dos métodos de colecta seminal: electroeyaculador y vagina artificial
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2018-03)La aplicación de la inseminación artificial (IA) en cualquier especie requiere del mantenimiento del semen en condiciones no fisiológicas. En ovinos, la IA con semen refrigerado se encuentra más difundida que con semen ... -
Seminal plasma proteins interacting with sperm surface revert capacitation indicators in frozen-thawed ram sperm
(Elsevier, 2016-10)This study was conducted to evaluate the effects of interacting seminal plasma proteins (iSPP) obtained by AV or EE on frozen-thawed ram sperm in order to test the hypothesis whether this fraction could be sufficient to ... -
Toros o semen
(Ediciones INTA, 2023-12)Otro componente fundamental para tratar de completar la Información sanitaria y reproductiva de un rodeo bovino ya sea para carne o leche son los toros o el semen empleado para IA. En ese sentido, es importante también ...
