MORPHOFUNCTIONAL FEATURES OF IMMUNE FORMATIONS OF CHICKEN’S ESOPHAGUS AT THE AGE OF 210, 240 AND 270 DAYS

Abstract. We studied morphofunctional features of immune formations of the esophagus (except the esophageal tonsil area) of chickens from Shever’s cross 579 aged 210 (n = 6), 240 and 270 days (n = 5). During the work, we used histological methods of morphological research. It was found that in these age groups of chickens, immune formations are in the cranial and caudal parts of esophagus and they are submitted as single, minor accumulations of diffuse lymphoid tissue, prenodules, primary and secondary lymphoid nodules which show their morphofunctional mature. These accumulations are registered under the epithelium, near the small blood vessels, secretory departments of esophageal glands and their excretive ducts. There is a migration of lymphoid cells to the surface epithelium and epithelium of the esophageal glands, in places of their location.

The area, which immune   formations are occupied in the mucous membrane of the cranial and caudal parts of the esophagus, is not the same in the different age groups of chickens. In the cranial part of the esophagus, the biggest area of immune  formations is registered in chickens aged 240 days( 2,78 + 0,22%), and the smallest – in chickens aged 270 days(1,37+ 0,10%). In the caudal part, it slightly decreases with increasing the age   from 3,63 + 0,43(in chickens aged 210 days) to 2,20 + 0,32%(in chickens aged 270 days).

Keywords: chickens, esophagus, immune formation, diffuse lymphoid tissue, primary and secondary lymphoid nodules
