Milk lipoperoxide content was statistically lower in treated cows than in control ones, whereas, as to vitamins, only vitamin E increased in all the treated groups compared to control. Taken together, the results of this study confirm the efficacy of antioxidant administration in the early postpartum of dairy cows and suggest that an excess in antioxidant administration may result, paradoxically, in an increase in ROS generation.
