The spread of liver diseases in sows according to the results of the study of the biochemical composition of blood

Abstract

Sows in industrial complexes are affected by etiological factors leading to the development of liver pathologies (hepatopathy). The study of their distribution in sows on the basis of an in vivo study of the biochemical composition of the blood determines the relevance of the work.In order to clearly judge the prevalence of liver diseases in sows, three age groups of animals were defined: sows with one farrowing (pregnant replacement gilts), sows with 2 -3 farrowings and sows with 4 or more farrowings. Each age group included 100 sows and 100 suckling sows (total 600 animals). The selection of animals for blood sampling was carried out randomly.Sows in conditions of industrial complexes are affected by etiological factors that lead to the development of liver pathologies (hepatopathies). The study of their distribution in sows on the basis of intravital study of biochemical composition of blood causes the relevance of the work. In the blood of sows biochemical indices of inflammatorymesenchymal, cytolytic, hepatodepressive and cholestatic syndromes were determined. When interpreting the obtained indices, sows with changes in the biochemical composition of blood characterizing these syndromes were determined.The number of animals with biochemical changes in the blood characteristic of liver pathology increased among gestating and lactating sows with increasing number of farrows. The number of animals with hepatopathies in pregnant sows has increased from 20% in nursing pigs to 81% in animals which farrow 4 and more pigs, and in suckling sows from 34% to 85%. At the same time, with an increase in the number of farrows among sows with biochemical changes in the blood, which characterize the development of hepatopathies, the number of animals with blood parameters indicating the development of hepatosuppression and "oppression" of the synthetic function of the liver increases. Hepatosuppression was detected in 10% of cases in repair pigs, in sows with one farrowing, in 41.2% of cases. In gestating and lactating sows with 4 and more farrows, 92.6 and 92.9%, respectively.
