Monitoring of diseases of the digestive system of young cattle was carried out in agricultural enterprises of Ryazan region. The conditions of animal management were studied. The diagnosis of infectious diseases of the digestive system of calves was established taking into consideration the results of epizootological data, clinical signs, pathological anatomical picture on the basis of bacteriological, mycological, mycotoxicological, copro-ovoscopic and larvoscopic studies. Of the total number of 168,572 calves, the number of animals with diseases of the digestive system was 28,32-44,19%. Among mixed invasions in young cattle up to 6-8 months of age, Ostertagias were recorded in combination with Chabertias and esophagostomas. Calves at the age of 2-3 months often had additional eimeriosis. Among infectious diseases of young cattle, diseases of bacterial etiology amounted to 89,69-94,11% (50,98% - colibacillosis, 11,92% - proteus infection, 4,95% - salmonellosis, 4,53% - pasteurelliosis, 5,93% - pseudomonosis, 10,51% - streptococcosis, 2,10% - staphylococcosis, 0,47% - klebsiellosis). Laboratory tests of feed revealed microscopic fungi, but no mycotoxins were found. Mycotoxicosis in animals were not registered.
