Histostructure of the stomach of the turkey cross "Big-6" in the late embryonic period

The results of histological examination indicated that the morphological feature of the glandular stomach of 26-and 28-day old turkey embryos of the broad-chested breed of the BIG-6crossis a well-developed submucosal base, in which the lobes of deep glands are located, which showed the presence of a mixed nature of the secretion of neutral and acid mucopoly saccharides in histo-chemical reactions. The pronounced relief of the mucous membrane is due to the formed papillae, through which the excretory ducts of the glands open into the stomach cavity. In the folds between the papillae there are sur face glands, which mainly showed the presence of CHIC-positive substances, which indicates the neutral nature of their secretion. The morphological feature of the muscular stomach of the turkeycross"Big-6"is a pronounced asymmetry of the wall, which is due to the peculiarity of the structure of the muscular membrane. The inner cavity of the muscular part of the stomach is lined with a cuticle. The substance of the cuticle is determined in the excretory ducts of the superficial glands. The nature of secretion of secretory epithelial cells of the muscular part of the stomach by the end of incubation showed the presence of a protective barrier on the mucous membrane.
