The Effect of Food Type on the Anatomical and Histological Structure of the Canary (Serinus canaria) and White-eared Bulbul (Pycnonotus leucotis) Small Intestine
Objective: A comparative study of the histomorphological structure of
the wall of the small intestine of the canary (Serinus canaria) and white-eared
bulbul (Pycnonotus leucotis). Methodology: Five healthy birds from the canary
and white-eared bulbul. All birds were euthanized and dissected, and histological
staining procedures were used on the specimens. Result: Bulbul's intestine
length-to-body length and intestinal weight-to-body weight ratios were higher
than a canary's. According to morphological studies, the small intestine is divided
into three sections (duodenum, jejunum, and ileum). The duodenum was the same
in both birds. The jejunum of bulbul is structured into short and wide segments
that run caudally, and in canary, it forms a cone-shaped mass with outer centripetal and inner centrifugal turns, and the ileum is short in both birds. Histologically,
the small intestine was lined by simple columnar cells and goblet cells. At the
same time, the muscular mucosa of the duodenum is made up of two thick layers
of smooth muscle that are divided into inner circular and outer longitudinal bundles; the submucosa was a loose connective tissue layer that was thick, tunica serosa appeared as a thin layer of loose connective tissue on the areolar surface.
