AbstractFull Text

Bulls in Artificial Insemination (AI) Centres are generally trained with false mounting (FM) activity in order to improve the quality of semen. 360 ejaculates were collected via artificial vagina from twelve bulls. The bulls were subjected to each group according to the number of FM activity (FM-...

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

This study investigates the diluent effect on dairy bull liquid spermatozoa motility after thawing and refrigeration. Seven different semen diluents including TCG-15% egg yolk, TCG- 5% LDL, TCG-10% LDL, Biladyl-15% egg yolk, Biladyl-5% LDL, Biladyl-10% LDL and BIOXcell were assessed for post-thaw...

Abstract

Zinc (Zn) has important functions in mammalian reproductive processes. In cattle, Zn status can be classified as deficient, marginal, and adequate, depending on the plasma Zn concentration. In addition, Zn deficiency can lead to reproductive failure. The aim of this study was to investigate the...

Abstract

In the dairy breeding industry, prediction of bull fertility in artificial insemination (AI) is important for efficient and economically sustainable production. However, it is challenging to identify bulls with superior fertility applying conventional in vitro sperm assays. In the present study,...

Abstract

The aim of this study was to estimate genetic parameters for body weight (BW) at 150 d (Bw_150d), and 330 d (Bw_330d) of age and average daily weight gain (Dwg), and to estimate genetic correlations between these traits and semen characteristic traits: volume; concentration (Conc); motility in...

Abstract

This study aimed to evaluate the influence of bull age on fresh semen traits of Bali bulls. A total of 316 semen samples collected from six Bali bulls aged at 4, 6, and 8 years old (2 bulls of each age) were involved in this study. Fresh semen traits measured were semen volume, sperm concentration, ...

AbstractFull Text

Bali bull has great potential to be developed as a national meat source in Indonesia which can address concerns of meat importation. Bali bull farming only requires small holding system, has high fertility and low calf mortality as its advantages and is a growing enterprise by way of artificial ...

Abstract

The evaluation of sperm motion is crucial for processing of seminal doses for artificial insemination. Here, the combined effect of the type and capture area of three counting chambers, together with the type of diluent employed, on sperm motility was analysed. Ejaculates from thirteen Holstein...
