Abstract

In the context of artificial insemination, male fertility is defined as the ability to produce functional spermatozoa able to withstand cryopreservation. We hypothesized that interindividual variations in fertility depend on the proportion of the fully functional sperm population contained in the ...

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

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...

AbstractFull Text

The aim of this study was to determine the kinetics and sperm morphometry in sexed and conventional frozen semen of Brown Swiss bulls using the Integrated Sperm Analysis system. Ten straws of sexed semen and 10 straws of conventional semen imported from USA were used. The values of kinetics...

AbstractFull Text

The present study evaluated the accuracy of four methods, i.e. eosin-nigrosin, trypan blue, hypo-osmotic swelling test (HOST) and Hoechst 33342 (H342)/propidium iodide (PI) for assessing bovine sperm vitality. Frozen-thawed semen (n=30) of Holstein bulls was layered on 40%/80% percoll solutions to...

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

Prediction of male fertility with in vitro semen quality parameters remains a challenge for the bull industry. Fluorescein staining and computer-assisted semen analysis (CASA) ensure kinetically proper and functionally objective results to improve spermatological parameter control. Therefore, we...

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,...
