After the examination of horses in various horse breeding farms, including the hippodrome, schools, clubs, private stables and the horses of various ages, sex, and breeds, a wide spread of parasitic diseases was found, most often manifested in the form of helminthic infections and causing horse discomfort, preventing the development of young animals, reducing the working capacity and productivity of the adult population, as well as a number of different deviations. In order to protect animals from the harm caused by mixtinvasions, a hematological and biochemical study of horse blood was carried out. 32 animals infested with helminths were selected for the experiment. Blood was taken from experimental animals and examined in the laboratory. Studies have shown that invasions negatively affect the functional state of animals, while reducing the number of red blood cells, hemoglobin, basophils, platelets, total protein, urea, glucose, micro and macro elements, and increasing white blood cells, eosinophils, neutrophils, monocytes, lymphocytes, alkaline phosphatase, alananaminotransferase, aspartate aminotransferase, and bilirubin.
They studied the effectiveness of the drugs Praziver® and Ivermek® for horse helminthiasis. The drug “Praziver®” showed 100% therapeutic efficacy, used by the dose of 0.04 ml/kg against mixtinvasion of horses.
