This investigation was carried out on 17 Brown Swiss cattle in the Central Research Institute of Konya during the winter and lasting until the end of spring. Blood samples were taken from the jugular vein during the 7 th and 8 th month of gestation and after birth and on the 15 th day after parturation. Blood gas analyses and other chemical parameters were measured by using a Blood Gas Analyzer and Autoanalyzer Instruments. At the same time, liver biopsy samples were obtained from each cow during the experiment in order to observe any fat infiltration to the liver.
Blood-ionized calcium (ICa) and normalized calcium (norm Ca) concentrations decreased significantly at parturation. The same parameeters were significantly elevated on the 15 th day after parturation. The other metabolic profiles that were measured changed in significantly during the experiment. Fat infiltration to the liver was observed in a few cows but the level of fat infiltration was not severe.
