Fibrous connective tissue of the intestinal wall supports its functional stability and morphological integrity. Therefore, the aim of this research was to investigate the relationship between the fibrous components of connective tissue in the intestinal wall of chicken, which is characterized by different types of autonomous tone.The researches was carries out on laying chicken of Isa-Braun cross, in amount 33 animals, aged 1 year. According to the results of electrocardiographic and variation-pulse metric researches, poultry was divided into two groups: sympatotonics (CT) – 16 chickens and sympato-normotonics (CT-HT) – 17 chickens. After poultry slaughter, from each intestine was extracted wall samples, which were fixed in fluid Buena with the further making of paraffin sections. The coloring of histological sections was done, using the methods of Van Gieson's stain, Pachini and Weigert. The correlation between the size of all fibers of connecting tissue and the size of only elastic fibers in both groups of poultry was researched on ready histological preparations. These researches were carried out on the section of crypt of mucosa and muscle membrane by the way of using computer morphometry. The results of the research were worked out statistically.It was found, on the basis of the obtained results, that the researched correlation is characterized by the same dynamics in the both intestine membranes. Herewith along the whole intestine larger numbers of this correlation belong to chicken-CT. The part of elastic fibers in muscle membrane is higher than in mucosa. The maximum amount of elastic fibers in the content of all fibers of connecting tissue can be observed at the beginning of small intestine and along with it gradually reduces. At the beginning of the large intestine this part slightly increase, however in the end of the intestine has the smallest amount. The presented patterns is peculiar for the both types of poultry, so on the basis of this we can mention the relative stability of morphology of intestine connective tissue. And disclosed typological peculiarities of the autonomous tone allow to adapt the structure of fiber component of connective tissue to the functional characteristics of digestion during the respective type of autonomous balance.
