Abstract

Total antioxidant capacity is a combination of compounds that are able to maintain a biological system against the harmful effects of active oxygen species and nitrogen. Pregnancy is a period of increased metabolic activity that may lead to an imbalance between production and neutralization of reactive oxygen species (ROS). Comparison of Total Oxidant Capacity (TOC) and Total Antioxidant Capacity (TAC) among healthy cows and cows with retained placenta (RP) showed that changes in TOC during the transitional period in cows with RP and healthy cows until up to parturition were increased and changes in TAC from one week before parturition to parturition time was a decreasing trend in both groups. For TOC and TAC, there was a significant difference between healthy cows and cows with RP in all weeks. Therefore, there is a meaningful relationship between the amount of TAC and TOC in preparturient weeks and the occurrence of remained placenta.
