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

To achieve the targeted artificial insemination coverage with the current rate of semen production, without affecting the conception rate, it needs to reduce the number of spermatozoa per insemination dose in India as per international practice. Therefore, this study was planned to perform...

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...

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...
