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...

AbstractFull Text

The present study was undertaken to measure the functional and biochemical profile of freezable and non-freezable ejaculates of bull semen. Total sixty four ejaculates (eight ejaculates from each bull) were collected from six Jersey and two Sahiwal X H.F crossbred bulls and assessed for initial...

Abstract

The aim of this study was to assess post-thaw sperm quality following initial sperm selection using density gradient centrifugation (DGC) prior to cryopreservation. Ejaculates from four mature Charolais cross Kedah-Kelantan bulls were collected using artificial vagina at IBVK Pahang, Malaysia. The...

Abstract

Semen may be evaluated in bulls as part of the routine breeding soundness evaluation, for investigation of fertility problems and for use in artificial insemination (A.I.). The economic importance of a high breeding efficiency in farm animals emphasizes the benefit of accurate prediction of...

Abstract

Variations in fertility between bulls with comparable sperm quality could be due to differences in their seminal plasma (SP). The aim of this study was to investigate the effect of adding bovine SP from bulls of known fertility to SP-free sperm samples. After removal of SP by Single Layer...

Abstract

The objectives were to evaluate the effect of OptiXcell® diluent and centrifugation on cooled bovine sperm viability. It was hypothesized that motility and membrane integrity of cooled spermatozoa diluted in OptiXcell® would be higher than in frozen semen for at least 48 h, and removing seminal...

Abstract

The cryopreservation of epididymal sperm is an important technique that allows genetic material to be preserved, even post mortem. However, cryopreservation leads to increased oxidative stress and impaired sperm viability. Polyunsaturated fatty acid (PUFA) supplementation may improve certain sperm...

Abstract

BACKGROUND: Cryopreservation is known to have a detrimental effect on the motility, viability and membrane integrity of sperm cells. OBJECTIVE: The aim of this study was to investigate the effect of various amount of linoleic acid supplementation to the Tris extender, on bull sperm parameters, DNA...

Abstract

Objective: To explore the effect of BHT on cattle spermatozoa during cooling and cryopreservation. Methods: Pooled bull semen were diluted by Tris-Citrate-Fructose egg yolk (TCFY) diluent considered as control (0 BHT) and different concentrations of BHT (1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 mM) were...

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...
