Amides as cryoprotectants for freezing stallion semen: A review
(Elsevier B.V., 2005-10-01)
Stallion semen cryopreservation, despite its impact on the horse industry, is not an established technology. During the last years, a number of modifications have been proposed to the freezing process, however, a large ...
Advances in stallion's epididymal sperm technology
(Hippiatrika Verlag Mbh, 2010-01-01)
Freezing epididymal sperm is a method to preserve germplasm from animals with not only high genetic potential but also endangered species. In the equine some owners have chosen this possibility in cases of either severe ...
Bilateral Leydig cell tumor in stallion
(Elsevier B.V., 2007-10-01)
The authors report a rare case of bilateral Leydig cell tumor in a noncryptorchid stallion, describing the gross. and microscopic findings. An 8-year-old Appaloosa stallion was examined for a unilateral enlargement of the ...
Methods of Concentrating Stallion Semen
(Elsevier B.V., 2012-08-01)
Removal of excess seminal plasma is sometimes necessary to increase the quality and the longevity of cooled equine semen; moreover, this procedure is an indispensable step aiming to concentrate the sperm cells before ...
New seminal plasma removal method for freezing stallion semen
(2013-04-15)
Seminal plasma removal, an indispensable step in equine semen cryopreservation, is usually done by centrifugation, but this might cause mechanical damage to sperm. A new method for seminal plasma removal from stallion ...
Cooling of ejaculated and epididymal stallion sperm
(2013-09-03)
After a serious injury or sudden death, epididymis cauda sperm recovery and cryopreservation may present as the last opportunity to obtain genetic material from a valuable stallion. This study evaluated the viability of ...
Effect of Removing Seminal Plasma Using a Sperm Filter on the Viability of Refrigerated Stallion Semen
(2013-01-01)
Cooling of equine semen obtained from some stallions results in lower seminal quality and viability when the seminal plasma (SP) is present. The objective of this study was to evaluate the effect of the removal of SP using ...
Effect of Storage Time and Temperature of Equine Epididymis on the Viability, Motion Parameters, and Freezability of Epididymal Sperm
(2013-03-01)
The recovery of sperm from the epididymal cauda may be the last chance to obtain genetic material when sudden death or serious injuries occur in valuable stallions. However, the lack of technical knowledge regarding the ...
Freezing of stallion epididymal sperm
(Elsevier B.V., 2008-09-01)
Inseminations with frozen-thawed epididymal sperm have resulted in low-pregnancy rates of mares. If fertility of epididymal sperm could be improved, it would help to preserve genetic material from stallions that have ...
Influence of semen storage and cryoprotectant on post-thaw viability and fertility of stallion spermatozoa
(Elsevier B.V., 2007-04-01)
The aim of the current study was to verify that stallion, spermatoza could be cooled for 24 hours and then frozen. In experiment I, one ejaculate from each of 13 stallions was used. Semen was collected and split into two ...
