The present study was undertaken with the objective of determining the micrometrical values of blood cells of 8 normal and healthy adult Emu birds (>1 year of age), maintained under optimum conditions of feed and management at a private Poultry Farm, Anand. Mean, standard error and the range of all the micrometric values of the various blood cells of Emu are obtained. Total Erythrocyte Count (TEC), Total Leucocyte count (TLC), Thrombocyte count and Differential leucocyte count (DLC) were also determined. The mean±SE (range) of the length (μm) and the width (μm) of erythrocyte were 13.2±0.21 (12.8–14.4) and 6.45±0.24 (5.33–6.93). The mean±SE (Range) of the length and the width of nucleus of erythrocyte were 6.08±0.21 (4.8–6.4) and 2.96±0.12 (2.4–3.2), respectively. The mean±SE (range) of diameter (μm) of the heterophils were 10.78±0.43 (12.8–8.8), eosinophils were10.46±0.25 (11.2–9.6), basophils were 8.96±0.26 (8–9.6), small lymphocyte were 5.44±0.23 (4.8–6.4), large lymphocyte were 8.92±0.33 (7.6–10.4) and monocytes were 13.34±0.54 (11–16). The mean±SE (range) of the length (μm) and the width (μm) of thrombocytes were 5.6±0.26 (4.8–6.4) and 4.64±0.37 (3.2–6.4). This can serves as baseline for the future research on the micrometrical and morphological studies on the blood cells of emu.
