    Abstract:
    The aim of this study was to assess haematological changes in hand-reared pheasants (Phasianus colchicus) transported from intensive housing facilities to a pheasantry. Selected haematological parameters were monitored in a group of 100 pheasants (50 males and 50 females) aged of 9 weeks that were transported for 4 hours by a covered lorry in crates, with a total body weight of 12 +/- 0.5 kg per crate (Group C12 - floor space: 290 cm2/kg) and with a total body weight of 18 +/- 0.5 kg per crate (Group C18 - floor space: 195 cm2/kg). Blood samples were taken from 10 randomly selected males and 10 females before transport (CON group) and 20 hours after transport (C12 and C18 groups). Examinations consisted in determining the total erythrocyte and leukocyte counts, haematocrit values, haemoglobin levels and differential leukocyte counts, whereby the proportions of heterophil, basophil and eosinophil granulocytes, lymphocytes and monocytes of the total leukocytes were computed. The changes in the parameters of red blood cell count were manifested by an increase (P < 0.01) in the haemoglobin level, MCH (mean cell haemoglobin) and MCHC (mean cell haemoglobin concentration) values and a decrease (P < 0.01) in the total erythrocyte count and haematocrit level in both C12 and C18 pheasants, when compared with the control group of non-transported pheasants. C18 pheasants exhibited also a significant increase (P < 0.05) in MCV (mean cell value) value. When analyzing differential leukocyte counts, C18 pheasants showed a decrease (P < 0.01) in heterophil counts and H/L ratio, whereas values in C12 pheasants did not differ from the non-transported control group. Individual counts of lymphocytes were decreased (P < 0.05) in C12 pheasants, whereas basophil counts were increased (P < 0.01) in both C12 and C18 pheasants. Total leukocyte count was decreased (P < 0.01) in C12 and C18 pheasants. In conclusion, the specific requirements of pheasants, as primarily wild animals, for the density in crates should be respected during transportation and they should be transported at lower densities than other poultry species, at least 290 cm2/kg live weight should be provided.
