The objective of the present study was to estimate metabolic status in Holstein dairy
cows during different stages of lactation, on the basis changes of blood
concentrations of selected biochemical markers. Blood samples were collected from
100 Holstein dairy cows and blood serum parameters were evaluated. The cows
were allocated to four groups according to the production period, including Group 1 –
cows in early lactation (n=18), Group 2 – cows in full lactation (n=26), Group 3 –
cows in mid lactation (n=25), and Group 4 – cows in late lactation (n=31). Statistically
significant differences (P < 0.01) were found between the experimental groups of
cows in blood NEFA, BHB, TP, TG, TChol, urea, globulin, levels, and enzyme
activities of AST, ALT, ALP, GGT and LDH. The intensity of lipomobilisation (NEFA
or BHB concentrations) correlated positively (P < 0.05) with the markers of cell
damage or liver function impairment (tBIL.,serum AST, ALT, LDH and GGT
activities), but negati...vely (P < 0.05) with the circulating concentrations of compounds
synthesised in liver (glucose, TG and urea). All these biochemical metabolites may
be used as important biochemical markers in the determination of the metabolic
status in high-yielding dairy cows.
