Some haematological data for fallow deer (Dama dama) in England

The concentrations of haemoglobin, erythrocytes and leucocytes and the packed cell volume, plasma viscosity and some red cell indices were measured in the blood of 42 fallow deer and analysed with respect to age, season and sex. The mean haemoglobin concentration was greater in females than in males. In all the deer the number of leucocytes was considerably smaller than in the usual domestic mammals, namely, cats, cattle, dogs, goats, horses, pigs and sheep. Plasma viscosity was statistically greater in male deer more than two years old than in female deer of similar ages.
