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

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