The objective of the study was to examine haematological changes in breeding stags in the period of their sexual maturation. Haematological examinations were made on 16 clinically health stags of balanced weight and age, at the age of 10,15,20,25 and 30 weeks. The erythrocyte counts were found to increase highly significantly in stag blood from the 10th week of age (2.41 T.l-) to the 30th week of age (3.54 T/l). Haematocrit average values rising from 0.31 l/l to 0.38 l/l, total haemoglobin content in stag blood increased from 114.01 to 185.25 g/l. Other indicators of the red blood picture under observation did not exhibit these characteristic variations. The average values of the particular indicators in breeding stags ranged from 9.57 to 14.62 G/l for total leukocyte counts, from 0.25 to 0.52 G/l for basophilic granulocytes, from 0.10 to 0.15 G/l for eosinophilic granulocytes, from 4.49 to 6.70 G/l for heterophilic granulocytes, from 4.63 to 7.58 G/l for lymphocytes and from 0.14 to 0.17 G/l for monocytes.
