In the farms of the Udmurt Republic, the most common endoparasites of cattle are Fasciola hepatica, Chabertia ovina and Haemonchus contortus and their association. Feces samples were taken individually and examined by flotation and sequential swabs. The therapeutic efficacy of anthelmintic drugs has been studied in 780 cows. Animals’ infection rate was determined by triple helminthocoproovoscopic examination of fecal samples by flotation and sequential washing before and after antiparasitic treatments (15, 30 and 90 days after deworming). The high degree of cattle infection in various regions of the Udmurt Republic with fasciolosis and strongilatosis of the gastrointestinal tract is due to optimal climatic conditions for the regular transmission of the pathogen to susceptible animals. The therapeutic efficacy of anthelmintic drugs has been studied in 675 cows, which were divided according to the principle of analogues into groups consisting of 45 animals. According to the results of our studies in case of nematode monoinvasion, the most effective antiparasitic drugs are closanthin 20 % (the cost of one dose per animal is 77 rubles) and ivermectins (the cost of deworming per animal does not exceed 40 rubles). Analyzing the extenseffectivity of the studied anthelmintic drugs, we found that closantin 20 % at a dose of 1 is the optimal drug in terms of efficacy and cost for monoinvasions (ID – 100 %) with fasciola or strongilates of the gastrointestinal tract, and their association (ID – 93.3 %), 1.25ml / 50kg of animal weight.
