Abstract | Cattle endoparasites; pathogens of fascioliasis (Fasciola hepatica) and strongylatoses (Chabertia ovina, Haemonchus contortus and Bunostomum trigonocephalum) in the gastrointestinal tract are common at farms of the Udmurt Republic causing significant economic losses. Analyzing the epizootic situation for cattle helminthoses in the studied areas revealed thatmonoinvasion infestation with gastrointestinal fascioliasis and strongylatoses are observed while strongylatoses were more dominant than fascioliasis with infestation rate 59.59 %. Favorable conditions for the infestation with F. hepatica were noticed in the Central Uva district, where the infestation rare was 49.22 %. Meanwhile, the infestation rate in the northern Kez district of the Udmurt Republic was lower 16.77 %, three times lower than the Central Uva district. The dynamics rate of cattle invasion with fascioliasis and strongylatoses have been changing insignificantly, and the minimum number of infected animals has been reported in the northern Kez district. By assessing the therapeutic efficacy of anthelmintic drugs, it has been found that the Ivermectin series with the Closantel active substance are effective. In conclusion, all the identified helminthoses in this study have pathogenic effect on the macrohost organisms, but the most negative effect has been noted in course of associative fascioliasis and strongylatoses in the gastrointestinal tract in the form of mixed invasions that have direct and indirect effect on the animal leading to decreased productivity and direct losses for the livestock breeding farms.
