Abstract: Twenty-two crossbred dairy cows undergoing transition from two different farms of district Jalandhar, Punjab were taken-up to evaluate the oxidative stress and establish normal values for various metabolic parameters during different stages of the transition ie., far-off dry (FOD), close-up dry (COD) and fresh (F). Significant increase was observed in lipid peroxidation from FOD to CUD and fresh stage in both farms whereas, significantly low levels of superoxidase dismutase were observed during FOD stage in both farms with increasing trend in subsequent stage and again followed by declining trend after parturition. Significantly low levels of reduced glutathione were observed from FOD and CUD to fresh stage in farm 1 whereas, significantly low levels were observed between FOD and fresh stage in farm 2. Baseline values of various metabolic profile parameters (Hb, PCV, TEC, TLC, total protein, albumin, plasma urea nitrogen, creatinine, glucose, BHBA, NEFA, Ca, Mg, Na, K, Cu, Fe, Zn and inorganic phosphorus) were established during three different stages of transition period for both the farms for future reference.
