Dynamics of haematological indices (erythrocytes, leukocytes, haemoglobin, haematocrit, segmented and band neutrophils, eosinophils, basophils, lymphocytes, and monocytes) were studied in 11 male and 19 female fallow deer. The animals were shot at the game parks Rozhanovce and Roznava-Betliar. Average values of haematological indices in juvenile (younger than 2 years) and adult (over two years) fallow deer were as follows: Er - 10.95 and 9.84 T/l; Lc - 3.98 and 3.55 G/l; Hb - 13.12 and 13.08 g/dl; Hc - 0.48 and 0.49 l/l; Ns - 39.5 and 40.5 %; Nb - 4.5 and 6.4 %; Eo - 5.2 and 3.7 %; Ba - 0 and 0.2 %; Ly - 49.3 and 49.3 %; and Mo - 1.3 and 0.7 %, respectively. The differences between young and adult animals were not significant. Similarly, no significant differences were recorded in the juvenile fallow deer when evaluated by their gender. On the other hand, in adult animals significant (P<0.05) differences were observed between male and female animals in Hb (11.07 and 13.89 g/dl, resp.) and hematocrit (0.43 and 0.51 l/l, resp.). Seasonal changes were as follows (P<0.05): Er spring-autumn (average values 11.24 and 8.38 T/l, resp.), spring-winter (11.24 and 9.49 T/l); Lc spring-winter (3.97 and 2.5 G/l), summer-winter (4.64 and 2.50 G/l), and autumn-winter (5.53 and 2.50 G/l): Hb spring-summer (13.65 and 11.42 g/dl), spring-autumn (13.65 and 9.70 g/dl), summer-winter (11.42 and 14.17 g/dl), and autumn-winter (9.70 and 14.17 g/dl); He spring-summer (0.50 and 0.42 l/l), summer-winter (0.42 and 0.53 l/l), autumn-winter (0.44 and 0.53 l/l); Nb spring-summer (2.8 and 8.0 %), spring-autumn (2.8 and 6.6 %), summer-winter (8.0 and 4.3 %); Ly spring-winter (53.1 and 47.0 %); Mo spring-winter (2.2 and 0.2 %). These findings indicate a transition period in feeding. In winter, there is an increased proportion of dry matter in the diet due to nipping off tree twigs, and feeding hay and other dried foods. The change from winter to spring feeding is related to feeding green pasture-grasses and winter corns. As in domesticated ruminants, if may be suggested that There is a period of adaptation of rumen microflora and microfauna. This period is frequently associated with diarrhoea, which may cause the changes in haematological profile.
