SEASONAL DYNAMICS OF HELMINTHIOSIS OF HORSES IN THE TYUMEN REGION

Today, helminth infections in horses are one of the important problems for veterinary specialists, since the action of helminths significantly affects the general condition of horses, allergic and toxic manifestations of diseases are observed, external qualities deteriorate, and performance, endurance, and natural resistance are reduced, which leads to diseases of various etiologies. We set a goal to study seasonal features of the epizootic process of helminthiasis in horses in the Tyumen Region. The work was carried out in 2020 on the basis of the Laboratory of Innovative Horse Breeding of the Institute of Biotechnology and Veterinary Medicine of the State Agrarian University of the Northern Trans-Urals, the Tyumen Regional Hippodrome, and Allegro and Olympia equestrian clubs. A total of 312 animals were examined. The diagnosis was confirmed by common laboratory research methods. As a result of our studies, it was found that the maximum invasion prevalence caused by helminths Parascaris equorum was recorded in the autumn-winter period, and the minimum in the springsummer period; the invasion with Strongyloides westeri caused by causative agents from the suborder Strongylata was observed in the spring-summer-autumn period, and the minimum in winter, and the invasion with Oxyuris equi was recorded in early spring and minimal invasion in summer.
