PARASCARIS EQUORUM POPULATION IN HORSES IN DIFFERENT SEASONS OF THE YEAR IN THE TYUMEN REGION

The Tyumen region is characterized by extreme natural and climatic conditions, forty percent of the territory belongs to the regions of the Far North, winter is prolonged in the north of the region up to about ten months. The climate is dominated by the continental average temperatures of the central part are -23 °C in January, 16 °C to 18°C in July. Horse breeding is well developed in the territory of the region, and despite the medical and preventive measures carried out, parascaridosis and other types of horse helminths on complexes are widespread, and are an important problem for veterinary doctors. This is because animals are very sensitive to various diseases. Parascaridosis by single-hoof causes significant damage that affects their general condition, reduces endurance, performance, protective properties of the body, depletion, anaemia and deteriorates their external qualities. In order to prevent the harm of parascaridosis, we carried out studies to study the population of the helminth Parascaris equorum in different seasons of the year of the Tyumen region. As a result of the research carried out, it was found that the population of nematodes Parascaris equorum in single-hoof in the Tyumen region reaches the maximum invasion in the winter-autumn season, and the minimum is in the early spring and summer
