Abstract

The aim of the work was to diagnose diseases through autopsy and additional examinations and to determine the mortality structure and statistics in pigs of fattening groups on pig farms of industrial type. The objects of the study were 626 pigs from 15 pig «farrow-to-finish» farms in a number of regions of the European part of Russia. All animals were autopsied by the authors together with farm specialists in 2009-2019. Autopsy results in many cases are supplemented by the results of histological, bacteriological studies, ELISA studies, PCR. Over the entire period of the study of pigs in the fattening groups, streptococcosis, hypovitaminosis E - mycotoxicosis and actinobacillosis pleuropneumonia were most commonly diagnosed; intestinal inversion, enzootic pneumonia and gastric ulcer were somewhat less often. The absence of the viral causes of death, apart from the isolated cases of circovirus is indicative. When comparing the results of the study in the periods 2009-2015 and 2016-2019, attention is drawn to the increase in the frequency of cases of streptococcosis, intestinal inversion, cystitis and a sharp decrease in the frequency of cases of actinobacillosis pleuropneumonia. Changing indicators of the structure and mortality statistics for a number of years indicate the feasibility of pathological monitoring on pig farms, bearing in mind the constantly changing situation in diseases, depending on numerous factors affecting the number of animals.
