In adult chickens cross “Iza-Braun”, which were grown in conditions of poultry farms and were selected on the basis of analogues, there are two types of autonomous tone: sympathotonic (CT) — 16 specimen and sympatho-normotonic (ST-HT) — 17 specimen. Each group of birds is characterized by a combination of indicators of goblet cells, located on the villi of the intestinal mucosa. Great number of goblet cells in the duodenum (on 11 cells, P<0.001) and jejunum (on 3.2 cells, P<0.05) guts of chickens is combined with a smaller area of theirs secretory departments, when sympathotonic takes place. Nevertheless a smaller number of goblet cells in the iliac (on 8.9 cells P<0.001), blind (on 10.1 cells (P<0.001) and line (on 3.6 cells, P<0.05) guts correspond the large area of secretory departments. There is opposite dependence in normotonic autonomous tilt of the balance in the same areas of the intestinal wall.
While comparing villus height to the number of goblet cells, it was found that average saturation of a goblet cells of the villi in the small intestine is higher in chickens with a distinct tone, compared to chicken, autonomous balance of which is shifted towards normotony. However, in the colon the advantage of the value of this indicator are transferred to the second group of birds. These features of goblet cells allow maintaining relative stability of the digestive process at different types of autonomous regulation and may indicate the formation of compensatory morphological processes in the intestinal wall. They also stipulate the specifics of wall digestion process at different orientation independent regulatory reactions.
