We studied some hematological parameters in 36 cows from the autochthonous brachycephal Bulgarian breed - Rhodope short cattle. The blood for the study was taken twice - in spring and autumn, from cows bred in three different regions. We proved that the region and the season have a significant effect on hematological parameters. In the different regions, blood sugar ranges from 3.288 to 4.714 mmol/L, total protein from 50.67 to 58.48 g / L (P <0.001), cholesterol from 2.616 to 2.815 mmol/L, triglycerides from 0.258 to 0.595 mmol/L (P <0.001), creatinine from 217.8 to 254.1 μmol/L, Ca from 1.521 to 1.748 mmol/L, P from 3.073 to 3.218 mmol/L (P <0.05) and Mg from 0.649 to 1.497 mmol/L (P <0.001). Glucose, cholesterol (P <0.001), triglycerides (P <0.05) and minerals Ca, Mg (P <0.001) P (P <0.01) levels are higher in the fall compared to the spring while the levels of total protein (P <0.001) and creatinine (P <0.05) are lower in the fall compared to the spring.
