The purpose of the research is to study the spread of parasitic diseases that cause pathologies in horses and to evaluate the effectiveness of deworming with a feed and drug mixture that contains an effective anthelmintic and mineral supplement.Materials and methods. Seasonal and age helminth infection dynamics in young horses was studied by coproovoscopic and larvoscopic examinations monthly. A total of 50 foals were studied, namely, 20 foals aged under one year, 15 foals aged up to two years, and 15 foals aged up to three years. Infection prevalence and intensity in the horses was determined by the complete helminthological dissection of the gastrointestinal tract per K. I. Skrjabin. The detected helminths were fixed in 70% alcohol.Results and discussion. The most common Strongylata species were Alfortia edentatus, Delafondia vulgaris, Strongylus equinus and numerous species of Trichonematidae. The studied foals were showed the maximum prevalence of the S. equinus infection of 80% in November, and the minimum, 35.7% in August; the A. edentatus infection was 78.6 % in January, and 46.6% in November, respectively. The D. vulgaris infection peak of up to 86.6% was recorded in November-December, and the minimum, up to 66.6% in March. The foals were infected with Trichonematidae throughout the year.
