Abstract
Wide description of avian species is available
however, limited is known about pigeon anatomy. This study has been carried out
in 30 male and female pigeons (Columba
livia) in equal proportion. The birds were divided into 3 groups, Group A:
immature, Group B: adult and Group C: old, each having equal males and females.
Birds were slaughtered, digestive tract organs and associated glands were
collected and fixed in 10% neutral buffered formalin. For histometerical
studies, tissues were processed by the paraffin embedding technique and were
stained with Hematoxylin and Eosin. Microscopic studies of the different parts
of digestive tract showed the significant differences (P<0.05) among all the
three groups. Stratified squamous keratinized epithelium of tongue had mean
thickness values 84.53±6.53, 269.44±8.62 and 200.23±13.19µm in group A, group B
and group C, respectively. The lumen of the esophagus was consisted of
longitudinal folds along the length. Height of these folds increased with the
age advancement and esophageal growth. The mean thickness values of esophageal
epithelium were 226.37±5.45,
360.87±31.10 and
312.67±6.69µm in group A, B and C
respectively, which were significantly different (P≤0.01). Mean epithelial
thickness values of duodenum, jejunum and ileum were 19.09±1.88, 35.28±4.02 and
37.94±5.04µm, respectively. The results showed that the mucosal layers and other
layers were the thickest in group B, moderate in group C and lowest in group A.
This study of histological parameters of pigeon’s digestive system is an
addition in the basic knowledge of avian anatomy.
