Abstract

BACKGROUND: The cryopreservation process induces osmotic stress, membrane changes and production of reactive oxygen species resulting in damage to the spermatozoa. Together, the presence of oxygen in the extender aggravates the oxidative stress that further reduces the cryosurvival rate of sperm...

AbstractFull Text

Bulls in Artificial Insemination (AI) Centres are generally trained with false mounting (FM) activity in order to improve the quality of semen. 360 ejaculates were collected via artificial vagina from twelve bulls. The bulls were subjected to each group according to the number of FM activity (FM-...

Abstract

The purpose of the study was to investigate the effects of concentrations of low density lipoprotein (LDL) in the semen extenders on the quality of semen after frozen-thawed process. Three young offspring, derived from Ten Tons Cows based on DHI data ranking, were chosen in this study. Semen was...

Abstract

Objective of this study was to compare cryosurvival of epididymal (EP) and electroejaculated (EE) sperm cryopreserved in liposome- or egg yolk- based extenders. Aliquots of EE sperm (n = 10 bulls) were cryopreserved with a liposome- (Optixcell; EEO) or egg yolk-based extender (Botubov; EEB). Bulls...

Abstract

The production of reactive oxygen species (ROS) during cryopreservation of semen alters the sperm motion and mobility characteristics, resulting in poor or failure of conception rate after artificial insemination (AI). Melatonin an antioxidant is able to modulate the effect of ROS and prevents...

Abstract

The aim of the present study was to evaluate the effect of sperm selection by single-layer centrifugation (SLC) performed before freezing on sperm quality after thawing of Fleckvieh bull semen. Ejaculates from 22 bulls were collected by artificial vagina and divided into two aliquots. One aliquot...
