Administration of equine Chorionic Gonadotrophin (eCG) to rams to improve the reproductive performance during the non-breeding season
Beracochea, Florencia; Manes, Jorgelina; Viera, Maria Noel; Santiago-Moreno, Julian; Ungerfeld, Rodolfo (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 ... -
Changes in the aerobic vaginal flora after treatment with different intravaginal devices in ewes
Manes, Jorgelina; Fiorentino, María Andrea; Kaiser, German Gustavo; Hozbor, Federico Andres; Alberio, Ricardo; Sánchez, Esteban O.; Paolicchi, Fernando (Elsevier, 2010-11)The objective of this study was to characterize the vaginal bacterial flora and subsequent pregnancy rates after AI in sheep subjected to 4 different estrous synchronization regimes – the use of two intravaginal devices ... -
Changes in the vaginal microbiota in ewes after insertion of intravaginal sponges at different stages of the oestrous cycle
Manes, Jorgelina; Fiorentino, María Andrea; San Martino, Silvina; Ungerfeld, Rodolfo (2018)The aims of this study were to determine if the ewe’ vaginal bacterial load differs according to the stage of the oestrous cycle; and thus, if the stage of the oestrous cycle when intravaginal sponges (IS) used for ... -
Effect of Seminal Plasma on Post‐Thaw Quality and Functionality of Corriedale Ram Sperm Obtained by Electroejaculation and Artificial Vagina
Ledesma, Alba; Manes, Jorgelina; Rios, Glenda Laura; Aller Atucha, Juan Florencio; Cesari, Andreina; Alberio, Ricardo; Hozbor, Federico Andres (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
Ledesma, Alba; Manes, Jorgelina; Cesari, Andreina; Alberio, Ricardo; Hozbor, Federico Andres (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 ... -
La IATF en bovinos para carne ¿puede alterar la relación del sexo de las crías?
Aller Atucha, Juan Florencio; Rosatti, Gustavo; Brunello, Gabriela Esther; Manes, Jorgelina (Ediciones Taurus, 2021-04)Varios factores incluyendo los tratamientos para sincronización del estro afectan la relación del sexo de las crías en bovinos. Además, limitada información está disponible con respecto al sexo de las crías en relación al ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
Hozbor, Federico Andres; Ledesma, Alba; Manes, Jorgelina; Rios, Glenda Laura; Kaiser, German Gustavo; Cano, Adriana Virginia; Luciano, Cecilia Ines; Alberio, Ricardo (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 ... -
Vaginal histological changes after using intravaginal sponges for oestrous synchronization in anoestrous ewes
Manes, Jorgelina; Campero, Carlos Manuel; Hozbor, Federico Andres; Alberio, Ricardo; Ungerfeld, Rodolfo (Wiley, 2015-04)To characterize the histological and cytological vaginal changes generated by the use of intravaginal sponge (IS) applied in oestrous synchronization treatments in ewes during mid‐non‐breeding season. Thirty‐five multiparous ... -
Vaginal mucus from ewes treated with progestogen sponges affects quality of ram spermatozoa
Manes, Jorgelina; Rios, Glenda Laura; Fiorentino, María Andrea; Ungerfeld, Rodolfo (2016)The use of intravaginal sponges (IS) to synchronize estrous onset in ewes provokes vaginitis, an increase in the vaginal bacterial load, and growth of bacterial species that are not present during spontaneous estrous ...
