Oxidative Stress and Antioxidant Status during Transition Period in Dairy Cows
The study was conducted on 20 Holstein X Sahiwal cross bred dairy cows, with an average milk production of 2,752±113.79 liters in 284±5.75 days during a single lactation, that were divided in to two groups of 10 animals. We investigated the oxidative stress and antioxidant status during the transition period in dairy cows. In this study, plasma level of MDA was considered as an indicator of lip...
متن کاملrelationships between trace elements, oxidative stress and subclinical ketosis during transition period in dairy cows
the possible relationships between trace elements, oxidative stress and subclinical ketosis during the transition period were evaluated in dairy cows. blood samples were obtained by jugular venipuncture at four times of the transition period: 3 weeks and 1 week before and 1 week and 3 weeks after calving. the highest concentrations of malondialdehyde (mda) and betahydroxybutyrate (bhb) were obs...
متن کاملOxidative stress and antioxidant status in dairy cows during prepartal and postpartal periods
The aim of the present study was to evaluate the indicators of oxidative stress (malondialdehyde [MDA]) and antioxidant status (ferric reducing ability of plasma [FRAP]; superoxide dismutase [SOD]; glutathione peroxidase [GSH-Px]; selenium [Se]; vitamin E) in dairy cows of the Slovak Pied cattle from 3 weeks before parturition to 9 weeks after parturition. The mean MDA concentration was signifi...
متن کاملRelationships between rumination time, metabolic conditions, and health status in dairy cows during the transition period.
The main objective of this experiment was to monitor the rumination pattern during the transition period in primiparous (PR) and pluriparous (PL) dairy cows and to investigate its relationships with metabolic conditions, milk yield, and health status. The study was carried out in an experimental free-stall barn and involved 32 Italian Friesian cows (9 PR and 23 PL) during the transition phase. ...
متن کاملMarkers of oxidative status in plasma and erythrocytes of transition dairy cows during hot season.
The study was carried out to assess whether hot seasons affect the oxidative status of transition dairy cows. Twenty Holstein cows were utilized. Eleven of those cows gave birth in spring; the remaining nine cows gave birth in summer. Oxidative status was evaluated from 21 d before to 35 d after calving, determining oxidative markers in plasma [glutathione peroxidase activity, thiol groups, rea...
