[Basic hematologic values in gilts of the Large White breed and their crosses with the Landrace breed].

The basic haematological parameters (erythrocytes, haemoglobin, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, leucocytes, leucocyte type) were determined in 83 clinically relatively healthy gilts of the Large White breed and 85 gilts--crossbreds with the Landrace breed, at the age of five to seven months. The results were subjected to statistical processing. The erythrocyte counts are significantly higher in the crossbreds than in the gilts of the LW breed. The basic erythrocyte values, dependent on the number of erythrocytes, are significantly higher in the gilts of the Large White breed. The leucocyte counts correlate with those of the gilts of the same age; however, they are higher than in the adult sows. As a result of the evaluation of the leucocyte type, the gilts at the age of five to seven months were found to have a white blood picture of lymphocytic type. Further, a shift towards younger forms of cells of the granulocytic series was observed even in clinically relatively healthy animals.
