Abstract

ABSTRACT: In order to evaluate the antioxidant capacity of seminal plasma and blood in boars, 20 healthy males were randomly selected in two commercial swine farms, fed with commercial balanced diets. An ejaculate was obtained using the gloved-hand technique, and a 10 mL sample of blood was taken with EDTA. The activity of Glutathione peroxidase (GSH-Px; EC 1.11.1.9) and Superoxide dismutase (SOD; EC 1.15.1.1) in seminal plasma and blood was determined, as well as analyzing the seminal characteristics (volume, mass motility, individual motility, spermatic concentration); a hypoosmotic test (150 mOsm) was carried out. The mean GSH-Px activity was 25.3 ± 12.4 U/mL and 523 ± 106 U/g Hb for seminal plasma and blood, respectively. The SOD activity was 2.1 ± 1.8 U/mL in seminal plasma and 1005 ± 490 U/g Hb in blood. No correlation was found between the activity of the enzymes in seminal plasma and the activity in blood (P>0.05). The lack of correlation between the enzymatic activities in both systems suggests that the two antioxidant systems are independent.
