The distribution of helminths of small ruminants across ecological zones in the Kur-Aras lowland and their epizootological and epidemiological significance

During 2021-2023, 188 sheep and 105 goats from small ruminants in various ecological zones of the Kura-Araz lowland (plain, foothills, mountains) were studied with incomplete helminthological necropcy. 22 species of helminths (4-trematodes, 6-cestodes, 12-nematodes) were detected in sheep, and 17 species (3-trematodes, 5-cestodes, 9-nematodes) were detected in goats. Of these, 11 species are biohelminths and 11 species are geohelminths. When analyzing the detected species both in terms of the extent and intensity of invasion, as well as their distribution across ecological zones, it became clear that the main helminthic diseases cause serious economic damage to small ruminants. Thus, infection with helminths has led to a decrease not only in the quality of the animal's meat, but also in the quantity and quality of other livestock products (meat, milk, and wool). The detected species were characterized epidemiologically and epizootologically.
