Selenium levels and glutathione peroxidase activity in blood, plasma and reproductive organs in dairy cows

Selenium levels and glutathione peroxidase activity were determined in blood and reproductive organs in 12 Norwegian dairy cows at different stages of the oestrus cycle. Blood samples were collected before slaughter, and samples from genital organs were obtained as soon as possible after slaughter....

Description
Summary:Selenium levels and glutathione peroxidase activity were determined in blood and reproductive organs in 12 Norwegian dairy cows at different stages of the oestrus cycle. Blood samples were collected before slaughter, and samples from genital organs were obtained as soon as possible after slaughter. Blood and plasma selenium levels were significantly correlated with selenium levels in follicular fluid, and in ovarian and uterine tissues, but not with the levels in corpora lutea. The activity of blood glutathione peroxidase was significantly correlated with that in ovarian and uterine tissue, but not with activity in corpora lutea and follicular fluid. No effect of stage of oestrus cycle on selenium content or glutathione peroxidase in reproductive tissue was observed.
