Bull Semen Nicotinamide Adenine Dinucleotide Nucleosidase
A procedure is described for the purification of bull semen NAD nucleosidase. The enzyme was purified over 400-fold to a final specific activity of 9906 units per mg of protein. A spectrophotometric assay was developed in which the enzyme-catalyzed release of 3-acetylpyridine from d-acetylpyridine adenine dinucleotide was followed by measuring the increase in optical density at 232 mp. At pH 7....
متن کاملSperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملSemen Ejaculates Characteristics, in vitro Fertility and Their Interrelationships in Sahiwal Bull Semen
This study aimed at determining the physico-morphological attributes, in vitrofertilityand their interrelationships in semen of Sahiwal bulls. Semen samples werecollected weekly for 6 weeks from ten mature Sahiwal bulls divided randomly into 5 groups. The mean (±SEM) of ejaculate volume (mL), mass activity (score 0-5), progressive sperm motility (%), sperm concentration (106/mL), live sperm (%)...
متن کاملViability of bull semen extended with commercial semen extender and two culture media stored at 24 ° C
The aim of this study was to evaluate the viability of bull spermatozoa diluted with commercial semen extender and two culture media stored at controlled room temperature (24 °C) for 72 hours. Two Nguni bulls were used for semen collection with the aid of an electro-ejaculator. After macroscopic evaluation, semen was pooled and aliquoted randomly into Triladyl, modified Ham’s F10, and TCM-199 c...
متن کاملThe effect of antioxidant supplementation in semen extenders on semen quality and lipid peroxidation of chilled bull spermatozoa
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...
