Abstract
The research relevance is predefined by the widespread distribution of parasitosis, including helminthiases, alongside constant depasture on the same areas of pastures, which annually causes massive re‑infection of horses. In this regard, the research aims to identify the age, seasonal, and territorial dynamics of infection of horses with helminthiases in the context of the districts of the northern region of Kazakhstan. The primary research method was an experimental analysis that allowing to consider the dynamics and causes of horse helminthiases, associated with the prepatent period, the resistance of the organism, and the system of keeping and feeding horses. The study presents the results of studies of horse helminthiases on the territory of the Northern region of Kazakhstan, covering 4 regions that currently exist in 61 agricultural formations. Faecal samples of 4,395 horses were examined by scatological methods and 126 samples – by incomplete helminthological autopsy. As a result of coprolarvoscopic and coprological studies, it was found that in horses, the dominant representatives among the invasive larvae of strongylates are small and large palisade worms. In scatological studies, strongylatosis of the gastrointestinal tract was recorded in 63.9% of cases, oxyurosis in 40.8%, and parascariasis in 25.9%. The study also presents the results of post‑mortem diagnostics, which was carried out during the slaughter or due to the death of the horse.
