The 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...
متن کاملBiologically active metal-independent superoxide dismutase mimics.
Superoxide dismutase (SOD) is an enzyme that detoxifies superoxide (O2.-), a potentially toxic oxygen-derived species. Attempts to increase intracellular concentrations of SOD by direct application are complicated because SOD, being a relatively large molecule, does not readily cross cell membranes. We have identified a set of stable nitroxides that possess SOD-like activity, have the advantage...
متن کاملSuperoxide Dismutase: A Predicting Factor for Boar Semen Characteristics for Short-Term Preservation
Superoxide dismutase (SOD), total antioxidant capacity (TAC), and thiobarbituric acid reactive substances (TBARS) in seminal plasma were evaluated on the basis of receiver operating characteristics (ROC) analysis as predictors for distinguishing satisfactory from unsatisfactory boar semen samples after storage. SOD on day 0 correlated significantly with progressive motility (r=-0.686; P<0.05) a...
متن کاملDL-Aspartic acid administration improves semen quality in rabbit bucks.
Recently, D-aspartic acid (d-Asp) has been suggested as being involved in mechanisms regulating reproduction activity in animals and human. In this study we analyzed the effects of DL-Asp oral administration on sperm production in the rabbit. Bucks from 60, bred in a genetic centre and used for semen production, were divided in 2 subgroups of 6 individuals. The treated group was fed with a conc...
