    Abstract: The aim of this study was to determine the effects of supplemental 
  drinking boron on morphology of ostrich chicks’ cerebrum. 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<SUP>-1</SUP> 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 &#956;m thick) 
  were stained with HE, Nissl&#146;s and argentaffin and then micro photographed. 
  It showed significant increase (p&lt;0.05 or p&lt;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<SUP>-1</SUP> supplemental drinking 
  boron promotes cerebrum development, neurons differentiation, neurite formation 
  and nerve fibers elongation of the cerebrum of 0-45 days old ostrich chicks.
