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 this study was to investigate the effects of catalase and pre-freezing equilibration during ram sperm cryopreservation on motility and membrane and acrosomal integrity of frozen-thawed semen, as well as conception rate following laparoscopic timedinsemination. Semen was collected from four mature Dorper rams, pooled and diluted in Tris egg-yolk extender basic solution (CON), or this ...

Camels represent part of the Arab heritage. The interest in developing assisted reproductive technologies and cryobanking for the conservation of animal genetic resources has recently increased. However, semen collections in camelids present many problems as sitting position during copulation, slow ejaculation and difficult animal handling. In these cases epididymal sperm from slaughtered or re...

| There are several types of antioxidants which can be use in buffalo semen preservation. The current study was performed to the influence viz., Coenzyme Q10 (CoQ10), L-Carnitine (LC), or N-Acetyl-Cysteine (NAC) added extender on freezability and fertility spermatozoa. Semen Egyptian bulls (n=5) were pooled extended with tris (1:10) without addition antioxidant (E1), i.e., 0.03 mM CoQ10 (E2), 3...

Artificial insemination (AI) is becoming more common in canine reproduction, permitting the use of shipped semen, assistance for geriatric or subfertile males, coverage of dominant females, and advanced reproductive technology such as intrauterine deposition of semen. AI may be performed with fresh, chilled, or frozen semen. All instruments should be clean and free of any chemical contamination...

Preservation of ram semen has an impact on the exposure artificial conditions to spermatozoa which was followed by overproduction reactive oxygen species (ROS) and resulted in functional damages spermatozoa. This study aimed determine effect combination chicken, quail, duck egg yolks with green tea extract (GTE) quality Sapudi at 5°C storage. Ejaculates more than 70% motility were divided into ...
