Association between ETFA genotype and activity of superoxide dismutase, catalase and glutathione peroxidase in cryopreserved sperm of Holstein-Friesian bulls.

Abstract excerpt

The aim of this study was to determine whether C/T missense mutation within the ETFA gene is associated with sperm antioxidant enzymatic activity. One hundred and twenty Holstein-Friesian bulls were genotyped by the PCR-RFLP technique (MwoI). Commercial straws of frozen-thawed semen were used to evaluate the activity of three antioxidant enzymes: superoxide dismutase, catalase and glutathione peroxidase. Among...
