Гельминты, обнаруженные у овец, относятся к классам Trematoda, Cestoda и Nematoda, простейшие – к классу Protozoa.В осенний сезон встречались представители семи родов паразитов желудочно‐кишечного тракта – Dicrocoelium, Fasciola, Moniezia, Nematodirus, Strongylus, Trichuris, Eimeria, в летний сезон были обнаружены представители только пяти родов  – Dicrocoelium, Moniezia, Nematodirus, Strongylus, Eimeria.Из результатов проведенных исследований следует, что природно‐климатические факторы среды оказывают существенное влияние на инвазированность овец в горном регионе Армении. Все обнаруженные нами паразиты оказывают пагубное воздействие на организм овец. Однако применяемые в хозяйствах рациональные методы дегельминтизации и эффективные лечебные средства предотвращают развитие болезней овец.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the research is to study the parasitic invasion of small ruminants in the mountainous zone of Armenia during summer and autumn, in this case to determine the invasiveness of parasites of the digestive tract of sheep.The material was feces collected from sheep on pastures in the coastal zone of the Getik River during 2022. The work was carried out at the Scientific Centre of Zoology and Hydroecology, National Academy of Sciences, Republic of Armenia. The material researched also included mollusks and oribatid mites – intermediate hosts of biohelminths.As a result of the study of parasitic invasion of small ruminants in the mountain zone of Armenia, the taxonomic composition of parasites was determined. Helminths found in sheep belong to the classes Trematoda, Nematoda, and Cestoda, protozoa – to the class Protozoa.In the autumn season, representatives of seven genera of parasites of the gastrointestinal tract were found – Moniezia, Dicrocoelium, Fasciola, Nematodirus, Strongylus, Trichuris, Eimeria, while in the summer season, only representatives of five genera were found – Moniezia, Dicrocoelium, Nematodirus, Strongylus, Eimeria.As a result of these studies, it can be concluded that natural and climatic factors of the environment have a significant impact on the structure of the helminth complex of sheep in the mountain region of Armenia.All parasites found can have a detrimental effect on the sheep's body. However, the severity of the invasion in the samples taken is not at the level that could lead to serious diseases in sheep. This suggests that the treatment methods used on farms are at a fairly high level.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Овцеводство</kwd><kwd>желудочно‐кишечные паразиты</kwd><kwd>биогельминты</kwd><kwd>геогельминты</kwd><kwd>промежуточные хозяева</kwd><kwd>река Гетик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sheep breeding</kwd><kwd>gastrointestinal parasites</kwd><kwd>biohelminths</kwd><kwd>geohelminths</kwd><kwd>intermediate hosts</kwd><kwd>Getik River</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abo El Hadid S.M., Lotfy H.S.
