Abstract
The work was undertaken to evaluate an influence of the physiological status of (lactating and dried-off) cows and growing conditions (farm) on the variability of selected macroelements in cow blood serum. The evaluation was done using random models (models of variance components) as well as the classical variability coefficient. It has been found that the cow physiological condition influences the concentration and variability of examined elements. Sampling dates to a greater extent modified the content of investigated macroelements compared to the farms. There has also been found a significant share of an interaction of these factors and random effects (the experimental error) in the variability of examined elements.
