Abstract: The objective of this study was to investigate whether consuming of Protected Glutamine (PG) before parturition in close up period would affect biomarkers of oxidative stress, immune system and Haptoglobin (HP) and Serum Amyloid A (SAA). About 36 pregnant Holstein dairy cows were assigned into two treatment groups based on their BCS and expected calving date in at student examination. Treatment groups consisted of glutamine supplementation 100 g day-1 per cow before calving (F), glutamine did not supplementation before calving (N). There were not any significantdifferences among treatments in DMI and BCS on 21, 14 and 7 days before parturation. There were not significant differences in the Total Antioxidant Status (TAS), Haptoglobin (HP), Serum Amyloid A (SAA), No Esterified Fatty Acids (NEFA) and blood and immune cells. The plasma Glutathione Peroxidase activity (GPX) was significant difference between two group and it seems that supplementation diets with glutamine on the close up period can enhanceplasma Glutathione Peroxidase activity (GPX).
