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 observed on the week 1 after calving. In contrast, the serum values of copper, zinc, albumin, uric acid and TIBC decreased after calving. After calving, zinc concentration showed a significant negative correlation with MDA concentration (p}, keywords = {oxidative stress,Trace elements,subclinical ketosis,Transition period,Dairy cow}, url = {https://ijvst.um.ac.ir/article_27968.html}, eprint = {https://ijvst.um.ac.ir/article_27968_77ddeeb9d643dc27184229a85abcd576.pdf} }
