Morphological features of the wall of the small intestine of diurnal quails of meat breeds

Abstract

The morphofunctional status of the digestive apparatus, including the small intestine, is decisive in the implementation of life-supporting functions both at the organ and at the organizational level, which is due not only to its participation directly in digestion, but also in providing immunogenesis with tissue components of the intestinal wall. However, in the scientific literature, the structure of the intestinal wall in newborn quails is not described fully enough, there are no comparative data on the morphology of the small intestine within the group of breeds belonging to the meat direction. The purpose of the study: to establish the features of the structure of the intestinal wall in diurnal quails of meat breeds. The breed features of the morphology of the small intestine of diurnal quails of the meat breeds Pharaoh, Texas and Japanese by n=4 were studied using a set of morphological techniques. It was found that the length and width of the villi prevail in the diurnal quails of the Japanese breed, as well as the number of goblet cells in the duodenum and jejunum compared with those of the Pharaoh and Texas quails, while the smallest values of the length and width of the villi, as well as the number of goblet cells, were revealed in the Pharaoh quails. The exception was the thickness of the serous membrane of the jejunum, which has the highest index in daily quails of the Pharaoh breed, and the lowest in quails of the Texas breed.
