title: Effect of vitamin E and selenium supplementation on oxidative stress indices and cortisol level in blood in water buffaloes during pregnancy and early postpartum period.
abstract: Pregnancy is a physiology state accompanied by high energy and oxygen demand that may lead to increased level of oxidative stress and development of metabolic and reproductive disorders in pregnant water buffaloes. In the present study, the alterations in serum cortisol and erythrocyte lipid peroxides and superoxide dismutase activities were examined in 28 pregnant water buffaloes supplemented with antioxidant nutrients, Vitamin E and selenium. Another 14 buffaloes did not receive any treatment during pregnancy to serve as negative control. Results of the present study suggested that pregnancy is associated with oxidative stress and supplementation of vitamin E and selenium may be beneficial by alleviating oxidative stress in water buffaloes.
