Abstract

The article presents the results of studying the influence of the conditions of keeping pigs in industrial pig breeding using the example of Khatas Pig Complex LLC in comparison with farms of various types, on spread of diseases caused by nematode parasitism. The study of the species composition of pathogens and the spread of intestinal nematodes was carried out using helminthoovoscopic studies using the F?lleborn method. A saturated sodium chloride solution was prepared. A total of 1236 samples of pig faeces were studied. Of these, 425 samples from the Khatassky pig farm were examined by helminthoovoscopic examination. 811 samples were taken from farms in the villages of Tabaga, Sibir, Uchur, from the farm of the boarding school for the disabled in the village of Kapitonovka, and from private farmsteads in the villages of Khatassy, Vladimirovka and the Poultry Farm.
