Blood cells from direct blood smears of 10 male and 17 female rusa deer were measured using micrometer. Red blood cell showed anisocytosis. The range in diameter is 4.0-8.0 micro m, with an average of about 5.2 micro m. One or two Howell-Jolly bodies were found during differential count of normal rusa deer blood smears. Neutrophil ranges in size from 12-15 micro m, averaging 13.5 micro m. They contained prominent pink granules and well-defined nuclear lobes. Eosinophil ranges in size from 12-16 micro m, averaging 14 micro m. They contained numerous small, round red refractile granules of uniform size which nearly cover the light blue cytoplasm. Basophil ranges in size from 13-16 micro m, averaging 14.5 micro m. Its nucleus covered by blue-black granules. Lymphocyte ranges in size from 7-20 micro m, averaging 10.7 micro m. Small lymphocyte is the major lymphocyte in rusa deer. Monocyte ranges in size from 14-18 micro m, averaging 16.0 micro m. It is not a common cell in the blood smear of rusa deer. Odd lymphocyte is the large lymphocyte that is difficult to identified as lymphocyte or monocyte. Odd lymphocyte was found in only 37 percent of examined blood smear and 1-2 percent of white blood cell counted.
