Twenty four hatched ostrich chicks were divided into six group (I-VI) and supplemented by the water with 0, 40, 80, 160, 320 and 640 mg L-1 boron, respectively for 45 days. Cerebrums were obtained and weighed after dissection then measured the transverse diameter, longitudinal diameter and height of cerebral hemisphere immediately. Paraffin embedded sections of cerebral tissues (4 μm thick) were stained with HE, Nissl’s and argentaffin and then micro photographed. It showed significant increase (p<0.05 or p<0.01) in each anatomy index of group IV in comparison with the other groups while group VI showed significant decrease. Histology study showed that neurons of the cerebrum of group I and II were alike, nerve fibers passed horizontally within the cortex. Neurons of group III were varied in size and shape and with abundance of nerve fibers passed horizontally within the cortex tighter. Whereas neurons of group IV had more types than the rest of groups and were well arranged from the edge to inside by size, the nerve fibers were rich and interweaved. In contrast, neurons of group V and VI were monomorphic with less neurite and nerve fibers were tenuous and sparse. Findings showed that 80-160 mg L-1 supplemental drinking boron promotes cerebrum development, neurons differentiation, neurite formation and nerve fibers elongation of the cerebrum of 0-45 days old ostrich chicks.
