The purpose of the research is to establish the species composition and contamination of saigas with the main helminths, as well as to determine the effectiveness of the supramolecular complex of albendazole with polyvinylpyrrolidone at helminthoses in the conditions of the West Kazakhstan region. Materials and methods. Incomplete helminthological autopsy according to K. I. Skryabin was used to study the contamination of saigas with helminths. Supramolecular complex of albendazole with polyvinylpyrrolidone was tested on 30 saigas spontaneously infected with gastrointestinal strongylates and Moniezia spp. Animals of different groups of 10 animals each were administered orally the supramolecular complex of albendazole with polyvinylpyrrolidon...
