Ambience-associated variation in serum biomarkers of oxidative stress in donkeys of arid tracts in India

Abstract

An investigation was carried out in donkeys to discover serum biomarkers of oxidative stress during moderate and extremely hot conditions. Serum biomarkers included vitamin A, vitamin C, vitamin E, glutathione, catalase, superoxide dismutase, monoamine oxidase, glutathione reductase, xanthine oxidase, oxidase and peroxidase. These findings were compared with those obtained during the moderate conditions that served as a control. Serum vitamin A, vitamin C, vitamin E and glutathione activity decreased significantly during hot conditions, while serum catalase, superoxide dismutase, monoamine oxidase, glutathione reductase, xanthine oxidase, oxidase and peroxidase activities all increased significantly. It was concluded that hot ambient stress induced marked changes in the levels of biomarkers in the serum of donkeys, indicating oxidative stress.
