Evaluation of oxidative status of blood taken from jugular, mammary and coccygeal veins in dairy cattle
Oxidative stress is win of free radical on the antioxidant defense system . In the body , there is a balance between production of free radicals and the components of the antioxidant defense system. When the production of oxidant exceeds the capacity of antioxidant defense , a condition of oxidative stress is developed resulting in oxidative damage of vital molecules such as DNA , lipids , proteins and carbohydrates . The aim of this study was comparison of oxidative status of blood collected from jugular , mammary and coccygeal veins in dairy cattle . eleven dairy cattle with similar history , management and nutritional condition were used and blood sample were collected from jugular , mammary and coccygeal vein .Biomarkers of oxidative stress including SOD , MDA ,Catalase were measured .TBARS activity in jugular and coccygeal vein was significantly higher than milk vein(p
