“…According to Taklimi et al (2012), the greater height of the villi and the depth of the crypts of the intestines of broiler chickens increased body weight, when using humic acid as a feed additive. Due to Osama et al (2014), the height and area of the villi of the small intestine of the embryos of meat chickens of the heavy line is greater than that of the light. A decrease in the live weight of broiler chickens and a corresponding decrease in the depth of crypts and the height of the intestinal villi under the influence of thermal stress was reported by Marchini et al (2011).…”

“…The duodenum of the heavy line meat chick embryos compared with the light one had large indicators of the height and area of the villi. At the same time, in other guts of the thin section, such a difference has not been established (Osama et al, 2014). The area of the small intestine mucosa determines the ability of the entire intestine to absorb nutrients (Rougiere et al, 2012;Yamauchi et al, 2000).…”

“…Thus, an increase in the indices of the studied microstructures in one gut and the absence of a difference in another was observed in heavy breed birds. Higher values of the microscopic parameters of the duodenum: The area of the mucous membrane, the height of the villi, the depth of the crypts and smaller -in other guts of the small intestine in birds with a larger body weight under the influence of a pedigree or some other factor, a number of researchers report (Maneewan et al, 2004;Marchini et all., 2011;Rougiere et al, 2012;Osama et al, 2014). Both the absolute and relative thickness of the muscular tunic in all the studied two intestines of the thin section of the geese of a heavy breed was less, which is consistent with the information of Garcia et al, 2007;de Verdal, 2010;Rougiere et al, 2012, according to which, in the wall of the duodenum, jejunum and ileum of chickens of the light line of meat chickens compared with the heavy, the muscular tunic was significantly thicker, which, in the authors' opinion, compensated for the low functional activity of their stomach.…”

We studied the morphological features of the jejunum and ileum in middle and heavy goose breeds. The geese under six month of age of Gorkovskaya and Legart breeds were used in our research. Geese of a heavy breed had a large intestinal mass, length of the jejunum and ileum, thickness of the mucous membrane of the ileum, and a smaller thickness of the muscular tunic of the jejunum. Legart geese had greater villi density and crypt depth in the jejunum and greater height and density of the villi, the width of the crypts, and the ratio of the height of the villi to the depth of the crypts in the ileum. In all the guts of heavier geese, the density of crypts was lower. The geese of the heavy breed had larger number and area of the ganglia of the mental plexus and smaller number and area in the submucosa in the jejunum, while they had larger area of the ganglia of the submucosal plexus in the ileum. The number of argyrophilic and argentaffin apudocytes in the jejunum of geese of different breeds did not differ, when the Legart breed geese had lesser quantity of apudocytes in the ileum.

“…In agreement with our investigations, previous researchers have found that the muscular layer consists of inner longitudinal and outer circular layers, including Abumandour (), who examined falcon, and Hamdi et al (), who examined black‐winged kite. Meanwhile, Hassan and Moussa (), in regard to duck and pigeon, Madkour (), in regard to Muscovy duck, Wali and Kadhim (), in regard to the heavy and light line (ross) and De Oliveira Rocha and Inforzato de Lima (), in regard to the burrowing owl, mentioned that the muscular layer consists of two layers: the thick inner circular and ill‐developed outer longitudinal smooth muscle fibres. Moreover, the tunica muscularis in partridge (Banks, ) and in passerine (Ogunkoya & Cook, ; Samuelson, ) consisted of inner longitudinal, middle circular and outer longitudinal layers.…”

The rock pigeon (RP) and the laughing dove (LD) are common and widely distributed species in African countries, including Egypt. The present work was carried out to characterize the comparative features of the glandular stomach (proventriculus) in these two birds, which share diets and habitats. In both species, the proventriculus is an elongated spindle obliquely situated in the cranial two‐thirds of the body cavity. The length and weight of the proventriculus in the RP were about one and half times greater than that of the LD. Histologically, the proventricular wall generally consisted of the mucosa (thickest), submucosa, muscular and serosa layers. The proventricular glands occupied most of the wall of the proventriculus within the lamina propria of the mucosa. The glands are tubuloalveolar in type, consist of variable shaped lobules and are more condensed in LD than in RP. At the proventricular‐gizzard junction (PGJ), the proventricular glands were observed external to the tubular glands of the gizzard in the RP, whereas in LD, these glands end abruptly and are separated from the tubular glands of the gizzard by a short distance. A scanning electron microscopy (SEM) of the proventricular lumen in RP revealed that the openings of the proventricular glands have an irregular outline surrounded by concentrically arranged mucosal folds that resemble a rosette shape. In the LD, these openings have a regular outline surrounded by thinner, widely spaced mucosal folds. To our knowledge, these results identified the structure of the proventriculus in RP and LD for the first time.

“…It constantly adapts to variable conditions of internal and especially external media. The most intensive changes in the structure of the intestine certainly take place during the embryonic period, when at the beginning, cellulartissue components form, which unite into a morphological-functional composition (Shyer et al, 2013;Wali & Kadhim, 2014;Lilburn & Loeffler, 2015). Therefore, by the time a bird hatches, the intestine as well as most of the digestive organs is sufficiently formed according to the main indicators of structure and chemical composition, so chickens can consume food on their own (Sklan, 2001;Uni et al, 2003;China et al, 2017).…”

The connection between the separate structural parts of the mucous membrane of the small intestine of laying hens and the typological features of the autonomic tone were investigated. The studies were conducted on adult chickens of the cross-breed "Isa-Brown", which were divided into two groups: sympathicotonic chickens and sympathico-normotonic chickens, by the methods of electrocardiography and variation-pulsometry research. In the small intestine of the poultry of each group, the linear dimensions were determined first, and then the volume of the entire mucous membrane and its separate parts (villi, crypt, muscular plate), as well as the volume of connective tissue fibers in the crypt region. Research has shown that the villi account for ¾ of the volume of the entire mucous membrane. The volume of villi in the entire small intestine is more important in sympathico-normotonic chickens. This same poultry group has an advantage in the indicators of the volume of the muscular plate, but only in the duodenum and jejunum. In indicators of crypt volume, it turned out to be quite the opposite of the relationship with the typology of autonomous influences. In all studied intestines, the higher values of this indicator belong to the sympathotonic chickens. However, in terms of the volume of the entire mucous membrane, larger values still correspond to sympathico-normotonic chickens. Sympathicotonic chickens are inferior to them in the duodenum – at 1,005 mm3, in the jejunum – at 2,699 mm3 and in the ileum – only 78 mm3. Investigating the structure of the villi, we established that the volume of their epithelium in all three sections of the small intestine has higher values in the sympathico-normotonic chickens, and the larger volume of the lamina propria of the villi in the sympathicotonic chickens. At the same time, the connection with the type of autonomic tone is reflected in the ratio between the two layers of villi. In all three sections of the small intestine of sympathicotonic chickens, the ratio between the epithelium and the lamina propria was, on average, 65%/35%, or 2/1. In sympathico-normotonic chickens, this ratio varied and, on average, equalled 75%/25%, or 3/1. The increase in the tone of sympathetic centers contributes to the growth of volume both as the total amount of fibers of connective tissue, and also as separate elastic fibers in the area of crypt. According to the data,indicators of the sympathico-normotonic chickens are inferior to those of sympathicotonic chickens in all of the small intestine. It was also found that in both groups of poultry the volume of elastic fibers was approximately half the volume of all fibers of the connective tissue of the duodenum. In other sections of the small intestine, this figure was reduced to about ⅓. Consequently, the typological features of the autonomic tone, providing various trophic-regulatory effects on the mucous membrane of the small intestine, cause the formation of differences in its volume.
