AbstractFull Text

Equilibration is the one of the important steps of semen cryopreservation and it is the stage in which semen is cooled and phase changes occur. The condition of equilibration is mostly regarded; and success of the equilibration conditions depend on empirical experiences. The aim of this study was...

Abstract

BACKGROUND: The membrane and acrosomal integrity of sperm play a vital role in fertilization process; however they are compromised upon cryopreservation. OBJECTIVE: To study the effect of cholesterol-loaded cyclodextrin (CLC) on membrane and acrosome status of Hariana bull sperm during...

Abstract

The present study aimed to investigate effects of superoxide dismutase (SOD) and reduced glutathione (GSH) on the quality of frozen-thawed semen of Sahiwal bulls. Semen was collected twice a week for 8 weeks by artificial vagina from six Sahiwal bulls, kept at the Semen Production Unit Qadirabad,...

Abstract

Sixty-four ejaculates (eight from each bull) were collected from matured bulls. Ejaculates were classified into the freezable (n=49) and non-freezable (n=15) based on the initial parameters (motility ≥70%, mass activity ≥3 and post-thaw motility 50%). Correlation between functional and biochemical...

Abstract

The purpose of this study was to examine the effects of sub-lethal concentration of Xanthine oxidase (XO) on the post-thawed bull sperm quality. Semen samples were collected from four Holstein bulls, twice a week and during three consecutive weeks (n=24 total ejaculates). After collection in each...

Abstract

This study sought to compare the in vitro characteristics of fresh and frozen non-sorted (NS) and sex-sorted (SS) bull spermatozoa. Experiment 1: Holstein-Friesian ejaculates (n=10 bulls) were split across four treatments and processed: (1) NS fresh at 3×106 spermatozoa, (2) X-SS frozen at 2×106...
