The cytological details of blood cells of pig are focuses on cytomorphological Cytochemicals, Cytoenzymic, Scanning electron microscopic and Transmission electron microscopic. Largest basophil among all leukocytes. Unlike ruminants basophils of pig showed positive reactions with Peroxidase and Non specific esterase. Under scanning electron microscope erythrocytes of pig showed variable degree of concavity and most of erythrocytes were flat. Under transmission electron microscope, unlike ruminants cytoplasmic granules of eosinophils were devoid of rod like electron dense crystalloid...
