Pathomorphological changes in the early postnatal period in a calf with abomasum rupture

The main cause of the disease and death calves in early postembryonic period development is a feeding disorder. aim work was to analyze macro-and micromorphological changes digestive system calf with rennet rupture. To achieve this goal, standard microscopic research methods were used. Macroscopic examination revealed thickening, erosion mucous membrane esophageal gutter rollers, accumulation contents scar, mesh book, hyperemia membranes; thinning rupture wall; pronounced small intestine, thickening thick section; an increase mesenteric lymph nodes change their consistency. Microscopically, thickness epithelium, submucosal muscle layer most developed abomasum was, respectively, 0.68-0.72 mm, 0.23-0.32 mm 0.98-1.05 mm. Villi found folds numerous well – longitudinally oriented protrusions lymphocellular clusters bottom glands rennet; crypts colon. Thus, as result coarse feed, deceased has catarrhal erosive lesions trough; serous-catarrhal abomasitis signs hemorrhagic dilation perforation cardiac part; omasitis against background book blockage; reticulitis; ruminitis enterocolitis.
