Popis: One hundred fifty day-old sexed Vanaraja chicks (75 male + 75 female) were taken as experimental birds. Dissection of cranium was performed carefully and study of gross morphology of brain was undertaken at different ages in male and female birds. The brain in situ appeared like a ‘spade’ symbol in playing card but it appeared rather wider and globular in both sexes. The cerebrum varied from pear to oval or even globular in shape in both sexes. On dorsal view, the cerebral hemispheres appeared moderately convex and smooth surfaced. On ventral surface, ill-developed olfactory lobes were observed anteriorly on either side of the median fissure in both male and female Vanaraja birds. The hippocampus was located transversely to the posterior one third parts of both cerebral hemispheres. Duncan’s EQ ranged from 5.801 ± 0.514 (T3-Male) to 5.944 ± 0.451 (T1-Female) on 21st day. There was significant decrease (p
