Fig. 1
Changes in plasma or serum indices of oxidative stress in dairy cows with haemolactia (solid grey column, n = 11) or without haemolactia (void column, n = 11) after calving
Upper bars – maxima; lower bars – minima; horizontal bars through boxes – medians; GPx – glutathione peroxidase; MDA – malondialdehyde; SOD – superoxide dismutase. ** – P < 0.01 vs. non-haemolactic group

Fig. 2
Changes in plasma or serum indices of oxidative stress in dairy cows with haemolactia (solid circles, n = 6) or without haemolactia (void circles, n = 6) during the peripartum period. Values are expressed as the mean ± standard error of the mean. * – P < 0.05 and ** – P < 0.01 vs. non-haemolactic group; GPx – glutathione peroxidase; MDA – malondialdehyde; SOD – superoxide dismutase
