Normal reference values for hematological parameters were evaluated using 85 male Elk deer reared in Korea. The reference interval estimated were 6.01-9.93 (${ imes}10^6/mm^3$) for the red blood cell count, 10.90-19.70 (g/dl) for the hemoglobin concentration, 43.10-76.40 (%) for the hematocrit value, and 2.60-7.68 (${ imes}10^6/mm^3$) for the total white blood cell count. Our estimates were compared with previously reported values for these parameters in Korea and other countries.
