Comparison of the Conventional and Ultra-Rapid Freezing Techniques in Gabon Bucks Throughout the Year

Autor: Julián Santiago-Moreno, Rodolfo Ungerfeld, María Noel Viera

Publikováno v: Biopreservation and Biobanking. 19:312-317

The aim of this work was to compare the effectiveness of ultra-rapid freezing (UF) and conventional slow freezing (CF) to cryopreserve buck sperm throughout the year. During 1 year, semen from 10 adult Gabon bucks was collected by electroejaculation

Relationship between the seasonal changes in plasma testosterone and thyroxine concentrations with sperm cryoresistance in Gabon bucks

Autor: Rodolfo Ungerfeld, Julián Santiago-Moreno, Rosario Velázquez, María Noel Viera

8 Pág. Departamento de Reproducción Animal
Gabon buck is a breed with little marked seasonality in our latitude (Uruguay, 35° SL). The role of thyroid hormones on the regulation of their seasonal reproductive activity and sperm cryoresista

Administration of equine Chorionic Gonadotrophin (eCG) to rams to improve the reproductive performance during the non-breeding season

Autor: Rodolfo Ungerfeld, Julián Santiago-Moreno, María Noel Viera, Jorgelina Manes, Florencia Beracochea

8 Pág.
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 activity. In the fir

Seasonality of the stress response in goat bucks when there is use of electroejaculation for semen collection

Autor: Julia Giriboni, Daniela Casuriaga, Rodolfo Ungerfeld, Aline Freitas-de-Melo, Patricia Silveira, María Noel Viera

Publikováno v: Animal reproduction science. 226

Electroejaculation (EE) is frequently used to collect semen, but this procedure is both stressful and painful. In seasonal-breeding species the sensitivity to stressors might vary with season of the year when semen collection occurs, therefore, the p

Treatment of male goats with equine chorionic gonadotrophin during the non-breeding season does not affect their sperm characteristics during the subsequent breeding season

Autor: Rodolfo Ungerfeld, María Noel Viera, Julián Santiago-Moreno, Florencia Beracochea

Publikováno v: Tropical animal health and production. 52(1)

Equine chorionic gonadotrophin (eCG) is a hormone having FSH/LH effects. It can be used to enhance sperm quality in male goats (bucks) during the non-breeding season. In a previous study carried out during the non-breeding season, we treated ten buck

In most goat breeds, testosterone serum concentration and semen quality decrease during the nonbreeding season. However, bucks reproductive activity may be stimulated with the administration of equine chorionic gonadotropin (eCG). Therefore, the aim
