Abstract

Low sperm numbers in artificial insemination (AI)-doses are being used widely to make the best use of high genetic value bulls as well as sex-sorted semen. Sperm concentration needed for AI to obtain reasonable fertility, taking genetic value of bull and numerous others components into...

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

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...

AbstractFull Text

The aim of this study was to investigate some spermatological parameters of frozen Brown Swiss bull semen 32 years ago by flow cytometry and to determine how storage time in liquid nitrogen affects in vitro embryo production ratios. For this purpose, early necrotic, necrotic, viable and apoptotic...

Abstract

Objective: To evaluate effect of tris-extender supplemented with various concentrations of strawberry (Fragaria spp.) on bull semen preservability. Methods: Pooled bull semen were extended with tris-citrate-fructose egg yolk diluent (control, 0% strawberry) and various concentrations of tris...

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 effect of the long-term storage in liquid nitrogen on semen quality has not be reported. OBJECTIVE: The study measured the spermatological parameters of bull sperm after the long-term and short-term storage. MATERIALS AND METHODS: Vintage semen (obtained from 5 Brown Swiss bulls and ...

Abstract

Commercial doses of frozen bull semen for artificial insemination may have a certain percentage of morphological defects, despite being subject to prior selection. The aims of this study were to determine the prevalence of morphological abnormalities in commercial doses (n=55, r=2) of dairy and...

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...
