AbstractFull Text

Aim: Different types of extenders have a variety of components which show the tolerance effect on sperm protection during freezing procedures. In the present study, we have examined the impact of the extenders HF-20 and Tris, which were locally manufactured, and they are competing with commercial...

Abstract

BACKGROUND: Epididymal sperm cryopreservation represents the ultimate option to preserve spermatozoa of valuable stallions. OBJECTIVE: The study aims to evalute whether single layer centrifugation (SLC) prior to cryopreservation or after post-thawing improves the quality of stallion epididymal...

Abstract

The objectives of the present study were to analyze systematic effects on semen quality traits from fresh and frozen-thawed semen collected in and outside season. A total of 4,681 reports on semen traits of 121 stallions representing Arabian, Thoroughbred, Quarter Horse and four warmblood breeds...

Abstract

The present study was designed to study the adverse effects of cryopreservation and evaluation of the cryoprotective effect of reduced glutathione (GSH) and ascorbic acid (AA) supplementation on exotic jack semen in combination or alone. For this, 24 semen samples from four adult and fertile jacks...

Abstract

During semen cryopreservation, the sensitivity of equine sperm to oxidative stress is increased by the eliminated seminal plasma. Thus, antioxidant addition to the semen extender can be helpful to the sperm survival after freezing and thawing. This work aimed to test whether coenzyme Q10 (CoQ10)...

Abstract

Urospermia is a major ejaculatory dysfunction affecting stallions. It has been thought that urine-contaminated semen should not be cryopreserved; however, on select cases, urine contamination of semen cannot be avoided. A recent study suggested that urospermic semen can be cryopreserved after...

Abstract

Stallion sperm cryopreservation allows for long distance transport of sperm insemination doses. In addition, it can be used for long term storage and maintenance of sperm and gene reserves; e.g. in case of stallions participating in competition, endangered breeds, or prior to castration or removal...

Abstract

Protamines substitute DNA-binding histones during late spermatogenesis in sperm nucleus. Stallion sperm contains all three variants of these arginine-rich and positively charged nuclear proteins (P1, P2 and P3). Two variants of protamine-2, that is P2 and P3, constitute approximately 15% of the...

Abstract

The study aimed to compare two techniques for plasma semen removal from 11 stallions using semen centrifugation and semen filtration. Two hundred and thirteen semen samples were frozen and evaluated. The samples were distributed into two groups: centrifuged semen group (GSC) and filtered semen...

Abstract

Cryopreservation of stallion semen has not reached the level of efficiency and positive results described in other species. This is mainly due to the greater sensitivity of stallion sperm to the freezing process, showing higher rates of oxidative stress and plasma membrane damage, which trigger the ...
