Developmental study of small intestine in local chicken (pre hatch) (gulls gulls domesticate )

Abstract

Aims: The aim of this research was to found developed small intestine mucosa pre
hatching and first two weeks of the life local domestic chicken, also the importance of
carbohydrates in various chemical reactions, to study their distribution using special
dyes, such as: combined AB-PAS (PH-2.5).
Methods: The study is performed on 90 commercial of fertile eggs obtained from
birds market, where it is place in a small incubator and incubated with (37.5ºC) and
humidity (60%).
Result: There is a strong correlation between the intestinal epithelium's early
development and the growth and feed efficiency of local chicken. This study's goal
was to record the morphological, histological, and histochemical evolution of the)
duodenal, jejunum, and ileum ( mucosa in local chicken prehatch from days 15 to 21
of incubation. One hundred embryos or poults had their intestinal samples taken, and
these were examined under both light and dissecting microscopy. The villus height
increases significantly during which time, the junctional complex progressively
tightens the epithelial cells' apical end, and mature goblet cells become evident near
the tip of the apical of the villi. The Villus height rises gradually till it reaches a
plateau after 21 days. Before hatching, the shape of the villi gradually converts
projections that resemble fingers to those that resemble leaves around 21 day. The
significant morphological changes caused by consuming amniotic fluid before to
hatch, as well as nutritional variables, in the local chicken gut epithelium.
