Influiența preparatului E-Selen asupra statusului antioxidant la vaci în perioada de tranziție și lactație timpurie

Abstract

The purpose of the research was to determine and monitor the influence of E-Selen supliment on the antioxidant status of Flecvieh cows during the transition and early lactation period as well as all changes during this period. Determined parameters were GSH-Px; TAC; ROM; MAS. Most significant changes was observed in TAC and GSH-Px. Total antioxidant capacity (TAC) in the plasma during transition period in the experimental group is characterized by an increase in its value, compared to antepartum, and in the control group by a decrease; and maintaining higher values compared to the control group in the postpartum period. Results obtained in the dynamics of (GSH-Px) in plasma, characterized by maintaining a higher level in the experimental group compared to the control group, beginning with 20 days antepartum and ending 30 days p/p. Balance of antioxidant status during the transition and onset of lactation is of major importance for the state of metabolic health in highly productive milk cows. Administration of the E-Selen supplement to cows, 30 days before parturition, had an influence on antioxidant status indices, expressed by maintaining their positive dynamics compared to control group
