The study was carried out on 20 pigs from the Petrain breed that received powders and skins of black grapes in 1% ratio for 3 months. At the end of the experiment, samples were taken from duodenum, jejunum, ileum, colon, mesenteric ganglia, which were fixed with 10% buffered formalin, included in paraffin, sectioned and stained with HE. Following the examination, there was a diffuse lymphoid infiltration into the lamina propria of the mucous membranes studied, agglomeration of lymph nodes in the submucosa of the jejunum, ileum and colon in pigs from experimental group (EG). lymphoid follicles from mesenteric lymph nodes are larger and more numerous in pigs from EG compared to control group (CG). Polyphenols from black grape powder in this experiment resulted in significant lymphoplasmocyte infiltration into the mucosa, digestive submucosa and mesenteric lymph nodes and increased carcass weight at slaughter by 1.08 Kg compared to LM.
