The article presents the results of the study of the functional state structures intestinal immune piglets growing industrial and post–action process stress–weaning. It was established that the small intestine of piglets before and after weaning operates a big yeyuno–ilealPeyer’s patche and small Peyer’s patches. The structure of yeyuno–ileal Peyer’s patche of pigs 28–day age (weaning) at the macroscopic level allocated separate nodules that are intensely stained and clearly different, especially in the caudal part that can point to a marked reactivity of lymphoid tissue that forms their basis. At the stage of resistance (30 days after weaning) in the structure of yeyuno–ileal Peyer’s patche of pigs at the macroscopic level dome–shaped nodules are tight, so no free fields are not registered. At the histological level ofyeyuno–ileal Peyer’s patche of piglets before weaning registered primary and secondary nodules with reactive centers of reproduction, which is a sign of complete morphofunctional maturity lymphoid tissue, whereas when the piglets after weaning secondary nodules turned out far less, some of them have clearly formed shell, which may indicate the inhibition of immune responses within mucosal lymphoid tissue of the gastrointestinal tract or the development of immunodeficiency state of cellular immunity as a result of the stress of weaning.
