“…Some researchers point to its presence: in domestic hens (Casteleyn et al, 2010;Kuleshov, 2010;Pandit et al, 2018), in the African pied crow (Igwebuike & Eze, 2010), in the domestic goose (Liu et al, 2010), striated scope owls (Otus brucei) (Al-Saffar & Al-Samawy, 2016), guinea fowl (Singh et al, 2017), others point to its absence in domestic hens (Hodges & Michael, 1975;Gabella, 1985;Kachave et al, 2009). The mulard has sufficiently thick LMM which contain a large number of blood vessels (Eyhab et al, 2017).…”

“…Information about features of structure of the LMM of the avian gut, including poultry, is fragmentary and sometimes contradictory. The fact of the presence of LMM in the gut of birds is often indicated only: in the helmeted guinea fowl (Numida meleagris) (Singh et al, 2017) and in the Japanese quail (Coturnix japonica) (Wilkinson et al, 2018). A number of researchers speak about the absence of LMM of the gut: in the African pied crow (Corvus albus) (Igwebuike et al, 2010) and feral pigeon (Columba livia) (Udoumoh, 2016).…”

The aim of work was to determine the features of the microscopic structure of the lamina muscularis mucosae of the goose gut during the postnatal ontogenesis. According to the review of the literature, during the characterisation of the structure of the intestinal mucosa, researchers first pay attention to the condition of the villi, crypts, epithelial layer and their morphometric parameters, leaving the lamina muscularis mucosae aside. The intestinal lamina muscularis mucosae is an under-researched structure of the intestinal wall, the information on which is fragmentary and contradictory. The middle parts of the duodenum, jejunum, ileum, cecum and rectum of large grey geese of 13 age groups were investigated. The classic histological methods of staining by hematoxylin and eosin, aniline blue – orange (by Mallory), as well as azure II – eosin were used. It was established that the lamina muscularis mucosae of the goose’s small intestine is formed by two layers of unstriated muscle tissue: internal and external. In contradistinction to mammals, the thicker inner layer of the LMM has not a circular, but a longitudinal direction of cell location while by contrast the thinner outer layer is located in a circular direction. According to results of our research, the thickness of the lamina muscularis mucosae of the small intestine of the geese rapidly increased with age. The thickness of the duodenum corresponded to the value of adult geese at 60 days of age; jejunum, ileum, and rectum – at 21 days, cecum – at 7 days age. The lamina muscularis mucosae was thinnest in the duodenum, and it was thickest in the ileum. The lamina muscularis mucosa of the large intestine of geese is represented by only one longitudinal layer. By contrast, the thinner outer layer is located in a circular direction. Detailed information of the microscopic structure of the lamina muscularis mucosae of the intestine of geese can be useful for specialists, both morphologists and physiologists, for analyzing the histological preparations of the intestine of birds by the action of biotic and abiotic factors, as well as a basis of comparison with such structure in other species of animals. The description of the construction of this important microscopic structure of the intestine can serve a morphological basis for elucidating its function.
