The aim of the present study was to determine antioxidative/oxidative status in bovine colostrum by comparison of the total antioxidant capacity (TAC) as well as the intensity of lipid peroxidation (LPI) processes in samples collected several times after parturition. In conclusion, the present study clearly demonstrates that the TAC shows the dynamic changes in colostrum and milk from parturition up to day 7, whereas slight fluctuations of LPI were observed within the same period. Whether these changes are genetically controlled, or simply answer a current challenge of the mammary tissues requires further studies. The coupled determinations of TAC and LPI in colostrum and milk would allow evaluation of the potential beneficial effects on the neonate of dietary supplementation with antioxidant compounds of pregnant cows.
