Intestine embryogenesis in pigs of the hybridous Semirechenskaya breed

On basis of dynamics of morphofunctional parameters the author compared the development of small and large intestines in pigs embryos of the hybridous Semirechenskaya breed and initial parental forms - wild boar of European subspecies and domestic pig of the Landras breed. It was shown, that hybrids have the intermediate type of intestine development with considerable individual variability and irregular growth of structure elements, and also pronounced intestinal-gastric type of digestion. Activities of metabolism and digestion in hybridous embryos conditioned by formation of vacuoles and cavities in villuses enterocytes, scalloped texture of their lateral surfaces, slowed transformation of colon villuses to crypts and also intensive development of duodenal glands. Because in newborn piglets as hybridous as domestic it was recommended to take into account a weakening of protective mechanisms of intestine functioning owing to partial conservation of embryos texture of villuses, participated in metabolism processes.
