VALUES OF SELECTED BIOCHEMICAL PARAMETERS OF COWS’ BLOOD DURING THEIR DRYING-OFF AND THE BEGINNING OF LACTATION
Robert Kupczyński, Bożena Chudoba-Drozdowska
The research aimed at determing the values of selected hematological and biochemical parameters of cows’ blood characterized by acid-base equilibrium during their drying-off and the beginning of lactation. Acid-base equilibrium (RKZ) parameters and the level of hematological parameters were determined, and in plasma the following were determined: total protein and its fractions, glucose, macro-elements: Ca, inorganic P, Mg, Na, K and Cl as well as the following enzyme activity: AspAT, AlAT, AP and GGTP. All analyses were conducted three times: 4 weeks before delivery, one week and 4 weeks after delivery. The obtained results indicate that the drying-off period and the beginning of lactation do not influence the level of acid-base equilibrium parameters and hematological parameters, however they do influence enzyme activity, particularly AP and GGTP, which increased during the beginning of the lactation period. The status of acid-base equilibrium, glucose and total protein content in blood plasma of cows may c
