in order to determine calcium (ca), magnesium (mg) content and total antioxidant capacity (tac) of seminal plasma in buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen quality was evaluated, seminal plasma was then harvested by centrifugation and its ca and mg content were estimated and its tac determined. the ca ...

the aim of this study was to evaluate the effects of the addition of antioxidants (vitamin e, β- mercaptoethanol and their combination) to semen extender.  progressive motility, viability and ph of fresh ram semen were examined. ejaculate samples were collected with artificial vagina from three ghezel-merinose rams (3 years old) during non- breeding reproduction season. semen was diluted with a...

The aim of the present study was to investigate the effect of in vitro supplementation of selenium on fresh and frozen spermatozoa quality of buffalo (Bubalus bubalis) bulls. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 0.5, 1, 2, 4 and 8 μg mL-1 sodium selenite and the sperm motility and...

Boar semen is typically collected, diluted and cooled for AI use over numerous days, or frozen immediately after shipping to capable laboratories. The storage temperature and pH of the diluted, cooled boar semen could influence the fertility of boar sperm. Therefore, the purpose of this study was to determine the effects of pH and storage temperature on fresh and frozen-thawed boar sperm motili...

This study investigated the correlation between sperm motion parameters obtained by a computer-assisted semen analyzer and levels of reactive oxygen species in unwashed semen. In total, 847 patients, except for azoospermic patients were investigated. At the time of each patient's first consultation, semen parameters were measured using SMAS™ or CellSoft 3000™, and production of reactive oxygen ...

Black Bengal goat is the heritage and one of the potential genetic resources of Bangladesh. Genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in Black Bengal bucks were estimated in this experiment. Genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

In order to improve Boer goat semen quality during cryopreservation process, the influence of sugar supplementation on semen characteristics of sperm were investigated. Three experiments were carried out to investigate the effect of (a) addition of two monosaccharides (fructose and glucose) and two disaccharides sugars (trehalose and sucrose) (b) sugar combination (fructose and trehalose, sucro...

The objective of this study was to test the effect of four different diluents on the motility of goat semen stored at room and refrigerator temperatures. To achieve this objective, four West African dwarf bucks aged 10-12 months were ejaculated weekly for five weeks using the electro-ejaculator method. The ejaculated semen were extended using four diluents namely sodium citrate (T1), sodium bic...

This research was conducted to determine the effect of glucose supplementation in liquid semen diluent on quality Kampung Unggul Balitbangtan (KUB) spermatozoa. The chicken used is KUB as many 8 tails. procedure consists of; manufacture diluent, collection semen, dilution storage, and evaluation semen. Evaluation carried out motility, viability, abnormalities, plasma membrane integrity at 0 3 d...

A total of 120 ejaculates from six adult Black Bengal bucks were studied to determine the semen attributes and evaluate their fertility. The various semen attributes of fresh semen were volume, sperm concentration, mass motility, live spermatozoa and normal spermatozoa percentage. All the semen attributes differed significantly (P<0.05) except normal spermatozoa percentage between the bucks. A ...
