In thirty-three dairy cows--first calves, the influence of hypokinesis on biochemical parameters was studied over three lactation periods. The cows of the experimental group (n = 15) were reared in steel cages enabling only minimum movement, whereas the control group (n = 18) was housed loosely. It was found out that the permanent movement restriction led to a statistically significant decrease in hemoglobin and hematocrit concentrations, as well as in aspartate aminotransferase activity. In comparison with the control group, a significant decrease was also observed in substances of the lipid group--cholesterol, triglycerides and total lipids. Similarly, thyroxin and total proteinemia were lower.
