Helminths cause serious damage to the body of geese and ducks, reduce their productivity and negatively affect the quality of their meat. Therefore, studying the helminth fauna of domestic water birds and the dynamics of infection with parasites depending on the age, sex, distribution area and seasons of the year is one of the urgent issues. In total, 904 geese and ducks were examined by the method of complete parasitological dissection and 27 species of helminths were detected in the owners. In both geese and ducks, the percentage of infection was higher in males (77.27% and 50.45%) than in females (68.29% and 34.67%). The rate of infection with helminths was higher among birds up to 6 months of age than in other groups, regardless of the number of species. The species found in all age groups in birds are as follows: N. attenuatus, A. anseris, T. tenuis, H. dispar, C. anatis. It has been determined that domestic waterfowl have a higher percentage of helminth invasions in summer than in other seasons. The nematodes recorded in both geese and ducks in all seasons are: A. anseris, T. tenuis, H. dispar, C. anatis.
