The aim of PhD thesis was to check effects of balanced mixed feeding rations of dairy cows at the different stages of reproduction cycle, to ensure minimal occurrence of metabolic diseases, and improve the health of animals. Selected indicators for the metabolic profile of blood plasma in 10 cows in each established group (calving preparation, early lactation and peak of lactation) were measured. In terms of protein metabolism we found in two cases significant differences in plasma total protein concentration of cows in groups calving preparation and early lactation. The concentration of bilirubin in plasma increased in the group of early cows. But there were no found significant differences. On the contrary, in the case of AST, significant differences between cows in group calving preparation and early lactation were detected. Parameters of lipids metabolism did not significantly change as well as parameters of mineral metabolism. The blood plasma calcium concentrations show a significant difference in the groups calving preparation and early lactation. The highest values of calcium achieved cows in the group of calving preparation.
