The present gross morphological study was carried out on the brain of six healthy birds of Kadaknath Fowl in growing period (7 weeks to 16 weeks). The birds were procured from the Central Poultry Development Organization (CPDO), Eastern Region, Bhubaneswar and the research work was conducted at Krishi Vigyan Kendra, Jharsuguda, OUAT. It was found that the brain of Kadaknath fowl subdivided into cerebrum, cerebellum and medulla oblongata. The cerebrum was by far the largest part of the brain, and it comprised of two symmetrical halves called cerebral hemispheres. The shape of cerebral hemispheres was almost similar to the shape of entire brain. The apparently closely apposed cerebral hemispheres were separated by a median (longitudinal) inter hemispheric fissure (groove). A small transverse fissure separated the cerebrum from the cerebellum. The gyri and sulci were absent in the cerebrum. On ventral surface, ill-developed olfactory lobes were observed anteriorly on either side of the median fissure. The mid brain blended directly with the medulla oblongata posteriorly. The medulla oblongata was almost occupied dorsally by the cerebellum.
