Impact of vitamin E and selenium supplementation on oxidative parameters and reproductive efficiency of Egyptian buffaloes

Abstract. A total of 17 pregnant buffaloes were divided into 2 groups: treated group (n = 10), supplemented with vitamin E and Se (15 ml of Viteselen 15®), and control group (n = 7); not supplemented with vitamin E and Se. The blood sample was collected 4 weeks before and after parturition. The reproductive performance and blood biochemical analysis were conducted as calcium (Ca), phosphorus (P), magnesium (Mg), and progesterone (P4). Oxidative stressed parameters as malondialdehyde (MDA) and nitric oxide (NO), serum glutathione peroxidase (GSH-px), and superoxide dismutase (SOD) were measured.

Our results revealed that, treated group free from any postpartum uterine disorder with earlier ovarian resumption than control. The P4, Ca, P, and Mg was increased in the treated blood. Reduce concentrations of NO and MDA was found in the treated group. Meanwhile, a significant increase in SOD and GSH-px postpartum in the treated group was found compared to the control group. In conclusion, supplementation of buffaloes with vitamin E and Se during the transition period has a vital role, through the changes in different oxidative parameters and enhancing metabolic status, which optimizes Egyptian buffaloes’ reproductive efficiency.
