Abstract. The prevalence of coccidiosis diseases of various animal species has a global scale, so this problem has attracted the attention of veterinary specialists around the world. The purpose of this study was to study the specific features of the species composition and laboratory diagnostics of eimeriosis in young ruminants and to evaluate the effectiveness of treatment and prevention when using drugs from different groups. The material for the study was goats and calves. The research was carried out on the basis of two farms of the same agricultural holding in the Sverdlovsk region. Diagnostics was performed based on clinical and laboratory studies. Results of the study. The main pathogens in the goat breeding complex in goats of different ages were identified: the main causative agent of coccidiosis in 120-day-old goats was Eimeria arloingi, which accounted for 54 % of all detected oocysts in the samples. Eimeriosis occurred as a mixed invasion of Eimeria arloingi with Eimeria ninaekohlyakimovae (33 %) and Eimeria intracata (13 %). Eimeria arloingi (68 %), in 21-days-old goats – Eimeria ninaekohlyakimovae (32 %). Eimeriosis caused by Eimeria bovis was detected in 30-days-old calves (100 %). The article describes the results of using various anticoccidial drugs in the treatment and prevention of eimeriosis. A comparative evaluation of the therapeutic effectiveness of known coccidiostatics is given. The economic efficiency of different groups of drugs was evaluated. The scientific novelty lies in the fact that the morphological and quantitative assessment of parasitocenoses in eimeriosis in young ruminants was carried out. A comparative evaluation of the effectiveness of various traditional remedies and a new drug for the treatment of eimeriosis in calves and goats was carried out. Conclusion. Not all of the drugs used have the same therapeutic effectiveness both in terms of treatment time and the quality of elimination of the etiological factor.
