ABSTRACT
Hamedi S, Aghayee M., Pre and post
puberty histological and morphometrical changes in
cecum of Japanese quails (Coturnix coturnix japonica). Onl J Vet
Res.,
18(12): 923-928, 2014. Changes in cecum wall histology
of pre and post–pubertal quails are described. Groups of ten 30, 50 and 70 day old quails each,
were slaughtered for sections of proximal, middle and distal cecum stained by
H&E. Villi and cecal wall morphometrics
were determined. At puberty and later proximal cecum villus height and width
decreased, and nodular unit (ND) and fossulla
increased in size. In the central cecum villi shortened and widened. At puberty
and later there was diffuse lymphatic tissue in the
mucosa and crypt depth when the muscularis was at its
thickest. Villi were absent in the distal part of cecum. The findings suggest
that immune structures in the cecum of quails appear during puberty and are
most developed post puberty. The increased thickness of muscular layers of the cecal apex at puberty and later may increase the return of
particles to the colon.
