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 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 ... -
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 ...
