Statistical analysis of results indicated a significant positive correlation (r = 0.676, P<0.001) between manganese concentrations in serum and blood of cows. Manganese concentration measurements of 147 serum and 117 blood samples from cows in various stages of their production period and fed various manganese levels in their feed were used for determination of the range of reference values. The...
A method for blood manganese measurements has been described. The method provides high reproducibility of the concentrations measured. The coefficients of variation were 3.4% and 4.1 % for within-run and between-runs, respectively. The recovery of the method was 98.1 %. Manganese concentrations in the blood ranged from 6.27 ng/ml to 8.98 ng/ml. The measurements revealed that contamination of tubes...
