Pathoanatomical differential diagnosis of diseases causing sudden death of piglets for fattening

The aim of the work is to determine pathoanatomical changes in diseases that led to sudden death of piglets in fattening groups, allowing to differentiate these diseases by means of autopsy. To achieve the goal in 2016-2018, the authors conducted an autopsy of 134 piglets, including 45 heads which died suddenly, from fattening groups on pig farms of a number of agricultural enterprises. According to the results of autopsy and additional laboratory studies, diseases that were the primary cause of sudden (acute) death were diagnosed. The reason for sudden death were: intestinal volvulus -46.7% of all uncovered piglets, streptococcosis - 24,4%, mycotoxicosis-hypovitaminosis E and stomach ulcer - at 11,1% (both disease) and also ulcerative urocystitis - 6.7%. If intestinal volvulus was found, it was volvulus around the mesenteric 180 or 360 degrees and severe bloating. The intestinal wall has a dark red color due to venous stagnation and heart attack wrapped mesentery and intestines. In the lumen of the intestine there were an abundance of gases and liquid or liquefied red content. At the site of the inversion, at the root of the mesentery, there is an anemic strangulation strip. Pathological diagnosis of streptococcosis consisted of the following pathoanatomical changes: an increase in the spleen and many lymph nodes, serous-fibrinous or fibrinous pericarditis, warty endocarditis, myocarditis, white embolic heart attacks in the renal cortex, hemorrhagic meningitis. In 5 pigs which died suddenly, a complex of pathoanatomical changes for characteristic of mycotoxicosis and hypovitaminosis E was established: catarrhal, hemorrhagic, necrotizing, erosive gastritis, toxic liver dystrophy, foci of necrosis in the liver, granular dystrophy and necrosis of the heart muscle. In 5 pigs who died suddenly from gastric ulcer found anemia of the skin, muscles, serous integuments, mucous membranes, internal organs. In the stomach cavity is up to 2-3 liters of liquid and clotted blood. In the cardiac part of the stomach, an extensive deep ulcer of a round, square or rectangular shape, 3 - 4 х 4 - 6 cm in size, was found. The materials of the study are summarized in the table of differential diagnosis of diseases that caused sudden death of piglets on fattening. The paper presents pictures of piglets with pathological changes typical for each disease.
