Llama (Lama glama) semen collection via thermo-electric artificial vagina: effect of seasonality and collection interval on ejaculate characteristics
(Elsevier, 2015-09-09)
Adult male Llamas (Lama glama) (n = 6) were collected using a receptive female and a thermo-electric artificial vagina assembled with a polyethylene collection bag with the following objectives: (a) to develop a reliable ...
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 ...
Antioxidant effect of lemon balm (Melissa officinalis) and mate tea (Ilex paraguensys) on quality, lipid peroxidation and DNA oxidation of cryopreserved boar epididymal spermatozoa
(Wiley, 2015-11)
In this study, we investigated the protective ability of the addition of two antioxidant herb extracts, mate tea and lemon balm, on boar epididymal frozen–thawed spermatozoa quality. Testes from mature boars were collected ...
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 ...
Heterologous recombinant protein with decapacitating activity prevents and reverts cryodamage in ram sperm: An emerging biotechnological tool for cryobiology
(Elsevier, 2016-01)
During the last decades fundamental and applied aspects of mammalian ram sperm cryopreservation have been increasingly explored by scientists and biotechnologists. Many works report modifications in the composition of the ...
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 ...
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 ...
Effects of Campylobacter fetus on bull sperm quality
(Elsevier, 2020-09)
Campylobacter fetus is a gram-negative, motile, spiral or S-shaped bacterium, which induces campylobacteriosis. This disease causes decrease productivity of cattle. Although considerable research has been done on the role ...
Efecto de la suplementación con ciclodextrinas cargadas con colesterol al semen sexado bovino post-descongelación para su uso en producción in vitro de embriones
(UCOPress. Cordoba University Press, 2018)
Los espermatozoides bovinos presentan una bajo relación de colesterol/fosfolípidos en la membrana plasmática. Esta característica es importante ya que el colesterol juega un papel fundamental en el mantenimiento de la ...
Administration of equine Chorionic Gonadotrophin (eCG) to rams to improve the reproductive performance during the non-breeding season
(Elsevier, 2020-06)
In most ram breeds, there are annual changes in testosterone serum concentration and semen quality. This study aimed to determine if eCG administration to rams during the non-breeding season improves the reproductive ...
