[Dynamics of basic hematologic values in ewes during the course of a year].

Basal hematological values were studied in ten primiparous ewes of Merino breed at 15 time intervals in the period from birth to the last decade of the next gravidity. The mean erythrocyte counts ranged from 6.5 to 10.3 T . l-1, hemoglobin content from 101.3 to 121.3 g per l, hematocrit value from 0.32 to 0.37 1 per l, mean corpuscular hemoglobin concentration from 29.97 to 34.22 g per dl, mean corpuscular hemoglobin from 11.17 to 16.61 pg, corpuscular volume from 35.03 to 55.37 fl. The mean leucocyte counts were from 4.98 to 9.93 G . l-1, with 25.8 to 60.5% neutrophil granulocytes with segmented nuclei, 0.1 to 2.6% neutrophil granulocytes with rodlike nuclei, 0.8 to 8.7% eosinophil granulocytes, 0.0 to 0.33% basophil granulocytes, 30.3 to 71.2% lymphocytes and 0.4 to 4.5% monocytes. The quality of red blood component was not negatively influenced by a high degree of gravidity. In the time of parturition, neutrophil granulocytes highly dominated over the other types of white blood cells; the counts normalized since the seventh day post partum. Although statistically significant differences were calculated for some time intervals, the values were within the physiological limits.
