“…According to the previous studies ( Alshamy., 2018;Cruz et al, 2019;Sohel et al, 2019) and the current study, the small intestine in chicken is a thin tube consists of three segments, but there is no clear morphological demarcation to differentiate between them. In the present study, the large intestine in chicken have paired blind pouches (ceca) while, in other birds the large intestine holds a very small pair of ceca called, lymphoid ceca ( Hamdi et al, 2012) or holds a short single, left and not well developed ceca ( Al-Agele et al, 2020) or have paired ceca but not developed (Udoumoh et al, 2021). According to ( Abadi et al,.2019;Wedegaertner, 2021), there is a strong a correlation between diet and cecal mass: herbivores have larger ceca than carnivores, but omnivores are intermediate.…”

The objective of this study was to evaluate the morphological development and growth of different segments of the digestive tract at pre and post hatch period of broiler chickens. A total sixty birds divided into: thirty of embryos at the days 10 th , 15 th and 20 th of incubation period and thirty of chicks at the days 1 st , 15 th , 30 th of post hatch period were used, as ten for each age. The live body weight taken of each bird and after careful evisceration, their digestive tracts segments (esophagus with crop, proventriculus, ventriculus, small intestine and large intestine) were dissected.The location, shape and weight of the collected organs were recorded. Morphological results showed that esophagus divided into two regions by crop cervical esophagus and thoracic esophagus. Stomach was divided into two parts, glandular stomach (proventriculus) and the muscular stomach (ventriculus). Small intestine divided into three parts these are represented by duodenum, jejunum and ileum. Large intestine represented by cecum and colon. Data of the absolute weight of each organ separately, showed increasing with age, were the increasing significantly different between ages (p≤0.05), while the data of the weight of each organ separately relative to body weight showed increasing at pre hatch period and at hatch day, but these values decrease at 15th day of post hatch period.

“…Liebrkuhkn's crypts appeared in the anterior and posterior parts. Still, they are more numerous and more widespread in the posterior part, which is what appeared in other birds as in cattle egret (17), common pigeon (30), and Japanese quail (34). The secretory units in the front part were distinguished by having two types of secretory cells.…”

“…The results also showed that the lamina propria is formed of loose connective tissue of similar composition in the two parts of the ileum. These also appeared in the common pigeon (30), the cattle egret (17), and Indigenous Ducks (19). Liebrkuhkn's crypts appeared in the anterior and posterior parts.…”

This study was aimed to identify the histological and histochemical composition of the Ileum in the Slender-billed gull (Chroicocephalus genei). It was using histological stains and histological chemical techniques. The results showed that the Ileum was relatively long, so it characterized into two parts: an anterior part and a posterior part. The results showed that the mucous layer in the two parts consisted of villi that appeared conical in the anterior region and conical to a triangle in the posterior part, and the villi were more numerous and longer in the anterior part. The villi covered with a simple columnar epithelial tissue containing goblet cells in the two regions, but the goblet cells were significantly more numerous in the posterior part. The secretory units of Lieberkuhkn's crypts were more widespread and numbered in the posterior part. Clusters of lymphocytes also seemed close to the lymph nodule in the anterior part. The outer muscle layer consisting of one layer of smooth circular muscles appeared in the anterior part, while it was composed of three secondary layers in the posterior part. Histochemically, the two parts of Ileum showed different responses between them for PAS, AB, TB, BP and SB techniques. The study concluded that the histological and histochemical composition of the Ileum appeared somewhat complicated to suit the nature of the food of this bird.

“…Ultimately, the adult gastrointestinal tract is composed of proventriculus, ventriculus (gizzard), small intestine (duodenum, jejunum, ileum) and large intestine (caeca, coloretum) (Bacha & Bacha, 2000; Udoumoh et al., 2016). It is known that rapid physical and functional development of the gastrointestinal tract occurs during the immediate post‐hatch period (Sklan, 2001; Udoumoh et al., 2021). However, the complex molecular cascade that results in the definitive stomach and intestines, and the structural/functional events that occur in the developing gastrointestinal tract of the chick embryo during the late embryonic stage requires further investigation.…”

Morphological changes in the late‐embryo‐stage gastrointestinal tract of Nigerian indigenous chicken were investigated using anatomical techniques. The paraffin‐embedded sections were stained with haematoxylin and eosin and periodic acid Schiff‐Alcian blue (pH 2.5) stains. During the late pre‐hatch period, the framework of the stomach was already established, but glands were yet poorly developed. Randomly oriented pre‐glandular cells in the lamina propria mucosae at embryonic day (ED) 14 became organized into elongated simple tubular glands at ED 19 and assumed adult morphology at post‐hatch day (PD) 1. Acidic and neutral mucin deposits were associated with the glandular cells. In the small intestine, enterocytes of the tunica epithelialis mucosae transformed from cuboidal‐shaped cells (at ED 14) to tall columnar cells (at PD 1). Short crypts of Lieberkühn, goblet cells, microfold cells and enteroendocrine cells were evident at ED 19, while the lamina propria mucosae and submucosa contained mesenchymal cells, reticular cells and isolated lymphoblasts. Similarly, the crypts, lymphoblasts, mesenchymal and reticular cells were also associated with the lamina propria mucosae and submucosa of the caecum and colorectum at ED 19. It was inferred from these findings that extensive cellular and tissue modifications occur in the gastrointestinal tract within the narrow window of the late pre‐hatch period. The definitive gut tunics, epithelium, glandular tissues, immune‐competent cells and tissues are formed as a result. Thus, the embryonic gut of the bird is made capable of assuming its necessary functions of food digestion, nutrient absorption, water and ion re‐absorption, immune surveillance, antibody production and immune responses at hatch.
