Ecological and epizootological characteristics of the main helminthiasis of pigs in farms of the Altai Krai

Abstract

Animal parasites cause significant economic damage to pig farming. Of the parasitic diseases common to humans and animals, trichinosis is the most dangerous. The purpose of this work is to study the ecological and epizootological distribution of the main helminths of pigs in farms in the Altai Krai. Helminthoscopic studies to detect the spread of ascaris, metastrongyls, esophagostomas and trichocephalians were carried out in the same farms and in the same pigs. The viability of the detected ascaris eggs was determined bytheir appearance d, as well as by fculturing the eggs in a wet chamber in a thermostat at a temperature of 25-30C for 15-20 days. In pigs in the Altai Krai, according to CHA (complete helminthological autopsy) data, 3 types of metastrongyls are parasitized in the lungs: M. salmi, M. elongatus and M. pudentotectus. The dominant species is M. elongatus. The conducted studies showed that the objects of the external environment were strongly infected with ascaris eggs. According to the practical significance of pig nematodes in the Altai Krai, ascaris, metastrongyls, trichocephalians and trichinella should be considered. Thus, on the basis of the conducted studies, the assessment of helminthiasis of pigs in farms of the Altai Krai is given.
