Abstract
The research was focused on measurements of oxidative stress in dairy cows in different physiological states (dry period, 0-7 days early lactation, lactation 25-35 days). As indicators of oxidative stress were followed the activities of antioxidant enzyme glutathione peroxidase (GPX) and superoxide dismutase (SOD) on a herd of 15 heads dairy cows of Romanian Spotted breed. It was found that the activity of antioxidant enzymes shown different values in al three physiological states, but with no significantly differences. The results found shown that the stress of calving was installed.
