The aim of the study was to evaluate the effect of the addition of 20% bull seminal plasma to semen extenders on post-thaw sperm motility, morphology, and fertility. Two Merino rams at 3-5 years of age, 43 ewes, and one Holstein bull were used. Fourteen ejaculates were collected by the use of an artificial vagina, twice a day, at 60 min interval. Six semen ejaculates were extended with Tris-egg...
The present study was undertaken to investigate the effect of various levels of vitamin B12 in Tris extender on semen quality of Dallagh rams following the cooling and freeze/thawing process. Semen was collected from six healthy and mature rams with an average body weight of 60.0 ± 5.0 Kg using an electro ejaculator. High quality samples were mixed and diluted in Tris extender supplemented with...
Cryopreservation of semen from the Caspian brown trout (Salmo trutta caspius) and effects of extender type, freezing and thawing rates on fertilization ability were studied. After assessment of semen quality, one part of semen was diluted with three parts of different extender and decanted into 0.5ml straws. Freezing was carried out at two freezing levels, 1.5cm and 2cm above surface of liquid ...

This study was aimed to investigate the effects of omega-3, 6, 9 fatty acids on the characteristics of bovine chilled and frozen-thawed semen. For this purpose, oil containing different levels of omega-3, 6, 9 fatty acids were added to semen extender. To emulsify the oil in semen extender, polyethylene glycol (PEG) was added as a suitable solvent and the solution was finally sonicated. Five pro...

The aim of this study was to determine the effects of the antioxidants superoxide dismutase (SOD),glutathione peroxidase (GPx) and butylated hydroxytoluene (BHT) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. Ejaculates were collected from five Holsteinbulls and pooled at 37°C. The semen samples were diluted with a CEY extender containing addit...
the aim of this study was to evaluate the effect of bovine serum albomin (bsa) in stallion semen extender in cool condition. after collection, semen samples were pooled and divided into four equal parts. each part was diluted with one of the following extenders: 1) extender without bsa (bsa-0), 2) extender containing 5 mg/ml bsa (bsa-5), 3) extender containing 10 mg/ml bsa (bsa-10), and 4) exte...
This study was designed to determine the effect of different osmotic pressures on spermatozoa characteristics for cryopreservation of buffalo bull semen using tris egg yolk extender (TEYE). Semen of Nili-Ravi buffalo bulls (n = 04) housed at Semen Production Unit, Qadirabad, Sahiwal, Pakistan, was collected at weekly interval for 10 weeks. Three solutions of tris-citric acid-fructose with osmot...
This study was carried out to determine if a new antibiotic combination comprising of gentamycin, tylosin and linco-spectin (GTLS) in extender is suitable for improvement in fertility of liquid buffalo bull semen through artificial insemination (AI). Two consecutive ejaculates per week (4 weeks) were collected from three Nili-Ravi buffalo bulls of known fertility by using artificial vagina (42°...
