Abstract: Mastitis is the most common disease affecting large numerous of cattle. The study was carried out by him on 270 seemingly healthy cows in the Bikaner district over a period of seven months. Of these 270 cows tested, 25 control cows and 25 group cows had subclinical mastitis based on the modified California mastitis test. This study was performed to determine biomarkers of oxidative stress (malondialdehyde, reduced glutathione, vitamin E). Oxidative stress studies revealed a significant (p<0.05) increase in malondialdehyde and a decrease in glutathione levels. Plasma vitamin E levels were significantly (p<0.05) lower in clinically affected cows compared to healthy cows. No significant difference was found in vitamin E levels between asymptomatic (subclinical) and control groups.
