ASSOCIATIVE COURSE OF STRONGYLIDIOSIS OF THE ALIMENTARY TRACT IN CATTLE IN FARMS OF POLTAVA REGION
Introduction. Strongylosis is the most common gastrointestinal nematode of ruminants, represented by a significant fauna of parasites, the composition of which varies depending on the examined region. Establishing the species diversity of Strongylidae of the digestive tract and the features of the associative course in the composition of mixed invasions in cattle is relevant for increasing the effectiveness of therapeutic and preventive measures.
The goal of the work. To study the features of the associative course of strongylosis of the digestive tract in cattle in farms of Poltava region based on the results of lifetime and postmortem parasitological studies.
Materials and methods. The studies were conducted in 2024–2025 in farms and specialized slaughterhouses of Poltava region, in the parasitology sector of the laboratory of the Research and Educational Center for Animal Disease Diagnostics of the Institute of Veterinary Medicine of the National Academy of Agrarian Sciences, accredited by DSTU EN ISO/IEC 17025:2019, and the parasitology laboratory of Poltava State Agrarian University. They used coproovoscopy by flotation and sedimentation methods, the method of complete helminthological dissection of the gastrointestinal tract of cattle.
Results of research and discussion. It was established that during life, 74.5% of the infected animals were found to have associations of pathogens of strongylosis of the digestive tract of cattle as part of mixed invasions with parasites of the genus Eimeria (46.6%), Trichuris (36.9%), species Fasciola hepatica (20.5%), Dicro Strongyloides papillosus (16.4%), and posthumously - in 80.0% of the infected animals - Haemonchus contortus (46.9%), Trichuris skrjabini (34.4%), Trichostrongylus colubriformis (28.1%), Ostertagia circumcincta (25.0%), Chabertia ovina (21.9%), Nematodirus spр. (15.6%), Strongyloides papillosus (15.6%), Oesophagostomum spр. (12.5%), Fasciola hepatica (6.3%) and Dicrocoelium dendriticum (3.1%).
Conclusions and prospects for further research: In the farms of Poltava region, the fauna of strongylosis of the digestive tract of cattle is represented by nematodes of the species Haemonchus contortus, Trichostrongylus colubriformis, Ostertagia circumcincta, Chabertia ovina, Nematodirus spр. and Oesophagostomum spр. Strongylosis of the digestive tract of cattle most often (74.5–80.0%) occurs in the form of mixed invasions, where their members are protozoa of the genus Eimeria (46.6%), trematodes of the species F. hepatica (6.3–20.5%), D. dendriticum (2.1–1). (34.4-36.9%), S. papillosus (15.6-16.4%). The results we obtained on the characteristics of the course of strongylosis of the digestive tract in cattle will be used in conducting studies to determine the effectiveness of treatment measures, taking into account the associative course of invasions.
Keywords: cattle, strongylosis of the digestive tract, mixed invasions, nematodes, trematodes, eimeria.
