The aim of this study was to evaluate the haematological profile of Romanian Black and Spotted dairy calves during the first three months of life. Forty dairy calves, clinically healthy, from the Experimental Farm of the Research and Development Institute for Bovine Balotesti were screened for hemoleukogram (CBC) evaluation using the Abacus Junior Vet 5 haematology analyser. Comparisons between age groups (t1: 3-7 days; t2: 30 days; t3: 60 days; t4: 90 days, n = 10 heads/age group) were performed using One-Way ANOVA with post hoc Tukey test. Significant differences in the erythrogram components for platelets (PLT) and mean platelets volume (MPV) were observed (PLT: t1 vs t2: p = 0.0001; t1 vs t3: p = 0.0014; t1 vs t4: p = 0.0000; MPV: t1 vs t3: p = 0.0148). Statistical differences for leukocytes (WBC) and monocytes (MO) were also observed (WBC: t1 vs t2: p = 0.0397; t1 vs t3: p = 0.0214; MO: t1 vs t3: p = 0.0284). The main blood parameters studied were significantly different during the first three months of life of the calves, expressing a haematological adaptation pattern of the un-weaned dairy calves.
