The present investigation provides a baseline data on gross anatomy of respiratory system of Mizo local pig (Zo vawk). The values of the biometrical measurements were less corresponding to the smaller shape, size and lesser body weight of Mizo local pigs. They have relatively longer nasal cavities corresponding to the long facial part of the head. The laryngeal prominence is found absent on the ventral surface of thyroid cartilage. The first tracheal ring is slightly wider and larger and no fusion between tracheal rings. The right extra pulmonary bronchus is shorter and wider than left extra pulmonary bronchus. The surface lobulations are clearly visible on the lung corresponding to the thick interlobar and interlobular connective tissue.
