Antioxidant status is known to be a significant predictor of disease and mortality in infants, especially premature infants. It is unknown whether health of newborn animals is influenced by impairment of their antioxidant status. In order to characterize antioxidant status of calves and foals, trolox equivalent antioxidant capacity (TEAC) was measured in blood of cows and calves, as well as mares and foals, starting immediately after birth and continued over several weeks. Measurements of selected antioxidants should provide insight in their specific function and additional biochemical parameters should explain the causes for impairment of antioxidant status.
TEAC levels were practically equal in blood sera of mares (0.38 ± 0.15 mmol/l, n = 67) and newborn foals (0.38 ± 0.06 mmol/l, n = 35). However, antioxidant status was significantly impaired during the first week of life (0.24 ± 0.03 mmol/l, n = 18 at 7th day) and remained at low levels during the investigated period. The same pattern was found in cows (0.27 ± 0.07 mmol/l, n = 19), newborn calves (0.28 ± 0.08 mmol/l, n = 19) and calves after one week (0.20 ± 0.05 mmol/l, n = 19 at 5th day).
