Serum paraoxonase activity and lipid parameters in the early postpartum period of dairy cows
The effect of early lactation on serum paraoxonase activity was studied on 21 postpartum dairy cows and 19 non-pregnant late lactating dairy cows. A significant decrease of the paraoxonase activity was found in the early postpartum period compared to the late non-pregnant lactation. The serum triglyceride, cholesterol and LDL-cholesterol concentration were also markedly reduced during the postpartum period, while the serum HDL-cholesterol concentration showed no significant change. The results indicate that lower serum paraoxonase activity is associated with lipid metabolic disorders in the early postpartum period. A decreased serum paraoxonase activity may lead to the reduction of the antioxidative capacity and antioxidative protection during the early postpartum period.
