Summary. Species composition of helminths of the introduced Soviet breed goats is determined by 35 widely specific species in the Caspian region (Kabardino-Balkarian Republic). Biohelminths are represented by 13 species and geohelminths - by 22 species. The species composition of biohelminths is found in the introduced Soviet breed goats with different values and with combinations of species infracommunities of 5-14 species per individual. The Trematoda fam. is represented by 2 types (Dicrocoelium lanceatum Stilles et Hassall, 1896, Fasciola hepatica L., 1758), Cestoda fam. - by 7 types (Echinococcus granulosus Batsch, 1789, Moniezia expansa Rud., 1810, Moniezia benedeni Moniez, 1879, Avitellina centripunctata Rivolta, 1874, Thysaniezia giardi Moniez, 1879, Cysticercus tenuicollis Pallas, 1766 l., Coenurus cerebralis l.,), Nematoda fam. - by 22 species (Oesophagostomum radiatum, Trichostrongylus columbriformis Giles, 1829, Trichostrongylus axei Cob., 1879, Trichostrongylus skrjabini Kalant., 1928, Trichostrongylus capricola Ransom, 1907, Trichostrongylus vitrinus Looss, 1905, Bunostomum trigonocephalum Rud., 1808, Bunostomum phlebotomum Railliet, 1900, Nematodirus spathiger Railliet, 1896, Nematodirus helvetianus May, 1920, Nematodirus filicollis Rud., 1802, Nematodirus oiratianus Rajevskaja, 1929, Nematodirus abnormalis May, 1920, Nematodirus schulzi, Nematodirella longispiculata, Ostertagia ostertagi Stilles, 1892, Ostertagia circumcincta, Ostertagia occidentalis, Ostertagia orloffi, Ostertagia trifida, Ostertagia trifurcata, Haemonchus contortus, Chabertia ovina Fabricius, 1788, Cooperia onchophora, Dictyocaulus filaria, Protostrongylus hobmaeri, Protostrongylus raillieti, Protostrongylus skrjabini, Mulleria capillaris, Cystocaulus nigrescens, Trichocephalus skrjabini). The indicated species are registered with variations in the occurrence indices from 7.0 to 69.0% with the abundance index from 1.6 ± 0.4 to 134.5 ± 11.2 ind./ individual in the introduced Soviet breed goats. This indicates the need to develop measures to combat endoparasitoses, the parasitic systems of which have multiple biological protection. All the 35 broadly specific species of helminths in the imported Soviet breed goats form various uncontrolled communities of species as part of mixed invasions in Kabardino-Balkaria.

Keywords: Caspian region, Kabardino-Balkarian Republic, small horned cattle, goats, Soviet breed, biohelminth, geohelminth, invasion, occurrence index, abundance index.
