GASTROINTESTINAL STRONGYLATOSIS OF HORSES

The epizootic situation was studied on gastrointestinal strongylatosis of horses in Sosna, LLC of the Baltasinsky District, the Republic of Tatarstan. The study objects were horses of different age groups, breeds, and sexes, spontaneously infected by nematodes. Coproscopic studies were carried out by the modified helminthovoscopic Kotelnikov-Khrenov method with ammonium nitrate and the helmintholarvoscopic Shilnikov method. The generic assignment of pathogens of gastrointestinal strongylatosis of horses was determined by cultivating nematode larvae belonging to the Strongylata suborder. As a result of the coproscopic studies, it was found that horses of different age groups were invaded by pathogens of gastrointestinal strongylatosis. In December 2021, 30 horses were tested for helminthiasis. The results of the studies showed that 20 out of 30 animals had gastrointestinal Strongylata infections with 66.7% extense-invasiveness, and the intense-invasiveness of 1 to 37 egg specimens in the field of view. The remaining 10 horses were free of helminths. The studies indicate that the examination of the horses in Sosna, LLC detected intestinal nematodiasis the causative agents of which were nematodes of the Strongylata suborder, the genus Triсhonema. Thus, widespread parasitic diseases of horses on the farm were gastrointestinal strongylatosis, in particular trichonematosis.
