HEMATOLOGICAL PARAMETERS IN CALVES ON FARM BREEDING

Abstract

The aim of this study was to determine the value of some hematological parameters in the blood plasma of Holstein-Friesian calves, and their effect on the nature of the changes in the first month of age. For this experiment we selected 20 calves (10 male and 10 female) aged one month, farm-raised, whose diet was based on the milk and starter mixture for the calves. Blood plasma of the examined animals was tested for the following hematological parameters: red blood cell count, white blood cell count, hematocrit, hemoglobin and red blood cell indices MCH, MCHC, MCV. Statistical analysis revealed decreased values of all hematological parameters in tested animals except RBC, PCV and MCV. The results indicate a highly significant impact of these values in male calves. The coefficient of correlation between the tested hematological parameters indicates the level of justification ranging from significant to highly significant differences in tested animals. Key words: calves, erythrocytes, hemoglobin, hematocrit, hematological indices
