The dynamics of morbidity and the syndromic structure of liver pathology in young pigs during rearing and fattening

The polyfunctionality of the liver causes a wide range of causes for the occurrence of its pathologies, but the mechanisms of sanogenesis reduce the risk of disease development, although hidden, including reversible pathophysiological processes take place, which as a result forms the diversity of manifestations and the need for more detailed diagnostics of hepatopathies. The aim of our research was to study the age dynamics of morbidity and syndromic structure of liver pathology in young pigs. Studies on the structure and dynamics of liver disease in young pigs were conducted at two industrial complexes located in the Voronezh region, where animals of commercial hybrids (KBxLxY) were kept in typical premises and received compound feed corresponding to their age and physiological state. A wide range of indicators was determined in the blood, including markers of hepatopathies (AST, ALT and GGT), reliable changes of which were the reason for a more detailed study of liver functions. Based on the retrospective analysis of the total volume of information, clinically healthy animals (group 1) and those with liver pathology (group 2) were identified. Group 2 included patients with primary detection of liver diseases, which more objectively reflects the incidence rate, since chronic forms of pathology, in addition to the immediate causes of their occurrence, depend on the effectiveness of veterinary measures. The highest incidence of liver disease is observed in the middle of the growing period (45-60 days) and fattening (120-135 days). In the middle of the growing period, hepatitis is more common, the nature of the manifestation of which indicates its origin as a consequence of diseases of the gastrointestinal and / or respiratory tract. At the same time, alimentary risk factors increase the degree of manifestation of hepatopathies, as indicated by the presence of metabolic disorders and moderate accumulation of their toxic products.
