Abstract
Helminth infection in sheep and the structure of parasite complexes in different regions of Gorny Altai have been studied. Standard helminthological methods were used: helminthoovoscopy by the method of Fulleborn, Kotelnikov–Hrenov and helmintholarvoscopy by the Berman–Orlov method. The calculation of the average egg number was performed using the counting chamber located at All-Russian Scientific Research Institute of Fundamental and Applied Parasitology of Animals and Plants named after K. I. Skryabin. The species composition and helminth infection in animals were detected using K. I. Skryabin method of incomplete post-mortem examination. The highest infection level has been determined in Northern Altai (83,8 %). The helminth complex of sheep in Northern and Central Altai is represented by 10 and in South-Eastern Altai – by 5 species. Gastrointestinal strongylates dominate in the structure of parasite complex. The representatives of species Ostertagia, Haemonchus, Trichostrongylus, Protostrongylus, Dicrocoelium and Moniezia have the greatest epizootic significance. The 20 % water suspension of dry concentrate of antiparasitic preparation SKVS- AA (СКВС-АА) in various dosages has been tested. The antiparasitic preparation has shown 90–100 % efficacy against gastrointestinal helminthosis.
Keywords: helminths, sheep, infection, structure, parasite complex, preparations, efficacy.
