Abstract
Aim of this research was to investigate the influence of different age of Podolian grey steppe and Holstein Friesian cows, as well the effects of different breeds, on their hematological and biochemical blood profile. A total of 128 adult cows aged from 3 to 12 years were used in the study. Gained results show statistically significant differences (P 0.05) related to the age of cows. Total protein has ranged between 7.10 and 8.50 g/dl (Podolian grey steppe), and 8.13 to 8.48 g/dl (Holstein Friesian), without recorded statistically significant differences (P > 0.05) between the age, breed as well as the interaction of age and breed. The similar tendency can be seen regarding the other biochemical values (P > 0.05), respectively. Gain results have mainly shown a significant influence of breed on the aforementioned parameters, while the significant influence of age of cows was not present as well the interaction between age and breed.
