Abstract:
The concentrations of glucose, non esterified fatty acids (NEFA), β-hydroxybutyrate (BHB), cholesterol, malondialdehyde (MDA) and total antioxidant status (TAS) of 15 healthy crossbred dairy cows maintained under identical conditions in a farm, and fed on standard ration, during transition period were evaluated and compared with that of pre-transition and post-transition periods. The mean concentration of glucose (47.35±1.32 mg/dL) and cholesterol (95.83± 3.62 mg/dL) during transition period was significantly lower than pre and post-transition period. NEFA (0.576 ± 0.08 mmol/L) reported significant increase during transition. The mean concentration of BHB (0.638 ± 0.05 mmol/L) was significantly higher during transition period and the increase was persistent towards post-transition period. The level of MDA, an indicator of oxidative stress was higher during transition period (7.89 ± 1.16mmol/ml), indicating increased rate of lipid peroxidation during the period, whereas TAS did not show any significant change. The blood parameters assessed, indicated negative energy balance and increased lipid peroxidation product during transition period.
