DONKEY SECTION


Parameter/units Average Range Interpretation
RBC 1012/l 5.5 (4 - 7.1) Red blood cells, packed cell volume, haemoglobin:

Elevations in RBC, PCV, and Hb may occur in dehydration and with stress, excitation and exercise. A reduction in these values may occur with acute haemorrhage, chronic inflammation, renal disease, hepatic disease, parasitism, haemolysis, and haematopoietic neoplasia.

PCV % 33 (27 - 42) As above
Hb g/dl 11.0 (8.9 - 14.7) As above
MCH pg 20.6 (17.6 - 23.1) Mean corpuscular haematology:

Elevations occur with haemolysis. Reductions usually indicate iron deficiency.

MCHC g/dl 34 (31 - 37) Mean corpuscular haematological concentration:

Elevations occur with haemolysis. Reductions may indicate iron deficiency.

MCV fl 60 (53 - 67) Macrocytosis seen with regenerative anaemia. Microcytosis seen with iron deficiency.
WBC 109/l 10 (6.2 - 15) White blood cells. The total number of WBC is influenced by the numbers of neutrophils, lymphocytes, eosinophils, monocytes and basophils. Leucocytosis is seen with septic and non-septic inflammatory conditions. Leucopaenia can occur

during viral infection and severe leucopenia with acute bacterial infections.

NEU % 38.3 (23 - 59) Neutrophils. Neutrophilia can arise transiently due to exercise, excitement and stress. Elevations are seen with septic and non-septic inflammatory conditions and acute bacterial infections. Corticosteroids, exogenous and endogenous, also cause a neutrophilia. Neutropenia can occur during viral infections.
NEU T 109/l 3.7 (2.4 - 6.3) As above
EOS % 4.0 (0.9 - 9.1) Eosinophils. Eosinophilia may be seen as a result of parasitism, allergic respiratory disease and eosinophilic leukaemia. Eosinopaenia is hard to evaluate as the numbers of eosinophils in normal donkeys are low.
EOS T 109/l 0.4 (0.1 - 0.9) As above
BAS % 0.05 (0 - 0.5) Basophils. Basophilia is rare in donkeys.
BAS T 109/l 0 (0 - 0.07) As above
LYM % 54 (34 - 69) Lymphocytes. Lymphocytosis occurs in response to chronic viral infections, autoimmune disease and with excitement or exercise. Large elevations in lymphocyte numbers can be seen in lymphoma. Lymphopaenia occurs as a result of stress, exogenous corticosteroid administration, severe bacterial or viral infections, endotoxemia and immunodeficiency.
LYM T 109/l 5.5 (2.2 - 9.6) As above
MON % 3.0 (0 - 7.5) Monocytes. Monocytosis can occur as a result of chronic suppurative and granulomatous inflammation. It may also be seen during recovery from viral infections of the upper respiratory tract.
MON T 109/l 0.3 (0 - 0.75) As above
Platelets 109/l 201 (95 - 384) Thrombocytes. Thrombocytosis is rare but can occur in bacterial infections. Thrombocytopaenia may be seen in disseminated intravascular coagulopathy (DIC), immunemediated thrombocytopenia, equine infectious anaemia (EIA), endotoxemia, equine ehrlichiosis, neoplasia, or as a result of severe haemorrhage. Artifactual reductions in platelet numbers can occur as a result of platelets clumping in EDTA.
RDW % 18.3 (16.1 - 22)
