Figure 5From: Changes in some Blood Micronutrients, Leukocytes and Neutrophil Expression of Adhesion Molecules in Periparturient Dairy CowsSerum concentrations of zinc (Zn), and copper (Cu) (μmol/l, LSM ± SEM) in blood samples taken one month before expected calving (-1), at calving (0), and one month after calving (+1) from ten dairy cows. Values with different letters within each parameter differ significantly (p < 0.05).Back to article page
