AB  - 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 negatively (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.

AB  - Introduction. The aim of this study was to determine and compare levels of blood serum calcium, inorganic phosphorus and magnesium in the peripartal period and during mid lactation in Holstein dairy cattle.Materials and Methods. Blood samples were collected from 12 cows in late pregnancy, 12 early lactation cows, and 12 mid lactation cows.Results and Conclusions. Serum calcium and inorganic phosphorus in blood of dairy cows in early and mid lactation were significantly lower compared to the values in the blood serum of dairy cows in late pregnancy, probably indicating the increased use of these macro elements by the mammary gland at the early stages of lactation. When the cows were in the lactation period, blood serum magnesium levels were significantly lower compared to the values of dairy cows during late pregnancy, probably indicating the increased use of magnesium by the dairy cows during lactation. The results show that the homeostasis of the macro elements examined in the blood of transition and mid lactation dairy cows was maintained, suggesting their adequate supply from alimentary sources.
