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.
