This paper presents values of biochemical blood parameters of seven Gatacko breed cows in early lactation, and their interpretation according to the lactational stage and nutrition. Mean concentrations of albumines, globulines and total proteins (40.14 ± 4.88, 52.57 ± 7.76 and 92.57 ± 10.50 g/l, respectively) indicated dehidration and hemoconcentration. Activities of AST and ALT (131.29 ± 28.52 and 73.14 ± 13.50 U/l, respectively) and hyperbilirubinemy (30.14 ± 6.96 µmol/l) indicated liver damage by presence of liver fluke larvae, potentiated with influence of lactational stage and low nutritive status. Mean values of cholesterole, urea and calcium concentrations (4.32 ± 1.75, 6.36 ± 1.78, and 2.42 ± 0.18 mmol/l, respectively) were in the physiological range, but finding of hyperphosphatemia (2.37 ± 0.47 mmol/l) and altered calcium-phosphorus ratio, indicated mineral disbalance in ration. These findings were in accordance with data from our previous study, conducted on the same cattle breed.
