Blood cell morphometry and leukocyte-thrombocyte profile of indigenous chicken Sikhar of Mizoram

The study revealed age-wise variation in size and number of blood cells of indigenous chicken. The size of erythrocyte was recorded highest at 4 months of age, while TLC declined gradually with age. Size and number of lymphocytes decreased in adults while the reverse was true for heterophils. TTC remained stable till 8 months and declined at 10 months while length and width of thrombocytes increased till 6 months and declined gradually till 10 months. Sikhar chicken appeared to possess characteristic blood cell size and number with the stage of life and different physiological state. Blood cells showed adaptive characteristics to altitude and management.
