The purpose of the study was to investigate effects on oxidant and antioxidant balance of early and late lactation period in goats. Blood samples used in study were obtained from Halep goats in early and late lactation period. Oxidative stress index (OSI) and lipid hydroperoxide (LOOH) and total oxidative status (TOS) and total antioxidant status (TAS) were analyzed to determined of oxidant and antioxidant balance. Plasma TOS, OSI and LOOH levels in early lactation period were significantly higher (P<0.001) than late lactation period of goats, while lower (P<0.001) level of TAS. It was concluded that lipid peroxidation decreased and antioxidant defence system mechanism in late lactation period in goats served as more positive than early lactation period.
