Abstract. Aim. Livestock is one of the main sources of protein human nutrition. Helminthiases infections are one of the limiting factors in animal husbandry. The most prevalent helminths of sheep and goats OF gastrointestinal tract are Strongylatoses. Studies on helminthiasis are absent during the last twenty years in the Chechen Republic. This paper analyzes the state of nematode infections of cattle in farms and private land plots of the Chechen Republic. The aim of the work is study of Strongylata infections of gastrointestinal tract of sheeps and goats: taxonomic composition, identification of extensiveness and intensity of infestation of strongylate invasions in the Chechen Republic.Material and methods. Tripes, intestines and lungs of 235 sheep 1-2-3-4-5-6-7-8-9-10-11-12-months of age, 1–2 years sheeps, 2–3 years sheeps and older than 3 years sheeps were studied. The follows methods were used: the method of opening full helminthological autopsy by Scryabin, the method of Fulleborn, helminthological research method by Berman-Orlov.Results. Livestock is infected by 14 species of nematodes of the suborder Strongylata, that are parasitic in the gastrointestinal tract. The most common nematodes are of genera Chabertia, Nematodirus, Haemonchus, Trichostrongylus, Ostertagia, Cooperia, Bunostomum.Conclusions. The results will allow to plan the most optimal anthelmintic activities.
