Hematology of 136 sheep (3 purebreeds and 4 crossbreeds) in Maehongsorn province was studied. These sheep were healthy animals under same condition (environment and management). Mean difference of hematological value were compared between breeds, sex and ages. The size and morphology of erythrocytic and leukocytic series were measured. Hematological values were compared by independent sample t-test and one way ANOVA with SPSS for Windows version 10.0 program. The results were demonstrated that almost blood values were less and more narrow range (mean+-2 SD) than the reference. Only PCV and red blood cell numbers were not differed between breeds. White blood cells and segmented neutrophils in the Dorset sheep had the greater number than the other breeds. Almost hematological values in crossbreed Bond-Native were less than the others. The number of lymphocyte, eosinophil and monocyte were significant differ between purebreed and crossbreed. Leukocytic series (except eosinophil) in male sheep were differ and greater than female sheep. Red blood cell size was larger than those of reference. The majority limphocytes in all breeds were small lymphocytes except in Bond sheep were medium lymphocytes.
