The microscopic structure of intermediate zone of stomach and saturation of her mucous membrane of immune formation of chickens in age 1, 2 and 3 years

General plan of microscopic structure of intermediate zone of stomach of chickens in age 1, 2 and 3 corresponds such wall of glandular part of stomach, however deep glands in her are absent. The immune formations of intermediate zone is located in lamina propria, rarer in tela submucosa and presented by all levels of structural organization of lymphoid tissue, that testifies to their morphofunctional maturity. The area of immune formations insignificantly diminishes with the increase of age of chickens.
