Biochemical Screening of Lipid Peroxidation and Antioxidant Protection in Imported Cows During Adaptation

Abstract

I n modern cattle farming, considerable economic dam- age is caused by the effects of oxidative stress suffered by high-production dairy cows at the beginning of the post-partum period, as also by hyperketoanemia (Ma et al., 2020).In economic conditions in the Russian Federation, the problem of dairy cattle breeding has acquired high importance.Thus, the development of dairy cattle based on the rational use of local breeds with the involvement of the imported gene pool of cultivated dairy breeds is being constantly improved.However, continuous monitoring of bio-chemical and physiological systems of imported animals is required to achieve and consolidate the positive results of this issue.One of the priority research areas in studying the biochemical mechanisms in animals during different physiological periods and manifestations of nosologically differentiated pathology is the evaluation of lipid peroxidation (LPO) and antioxidant defense system activity (antioxidant protection, AOP) (Kunwar and Priyadarsini, 2011).Hence, the oxidative phosphorylation, regulation of cell biomembrane permeability, synthesis of prostaglandins and ster-research
