Abstract: The purpose of this study was to measure the level of oxidative stress in animals and the mammary epithelial cells (MECs) isolated from goat milk. Saanen goats were allocated into three groups according to the first, second, and third month of the lactation period. Blood sample and the MECs isolated from goat milk were collected for measured malondialdehyde (MDA) concentration and glutathione peroxidase (GPx) activity. The results showed that MDA concentration and GPx activity in plasma from the second group was significantly higher than the first and the third group. On the other hand, MDA concentrations and GPx activity of the MECs isolated from goat milk showed no significant difference in the experimental groups. In conclusion, the oxidative stress of the goats during the lactation period occurred at both systemic and udder. In addition, the MECs isolated from goat milk can be used to analyze oxidative stress status of the mammary glands. However, MECs cannot be used to replace the plasma sample as the systemic oxidative stress marker and showed no correlation with plasma oxidative stress status.
