Abstract: Animal intestinal tract has a complex and dynamic microbial ecosystem, which plays a vital role in maintaining body health by promoting nutrient intake, host defense, immune regulation and so on.The structure and composition of colonies are different due to the changes of maternal body, diet, environment, physiological state and the interaction between different species.Waterfowls (including ducks and geese) are oviposition animals.Compared with mammals, its intestinal microbial system is special.In this paper, the establishment of intestinal microorganisms, the characteristics of microbial community structure and developmental changes in different parts of the intestine in waterfowl were introduced.The main functions of intestinal microorganisms in waterfowl were expounded from three aspects:The influence of intestinal microorganisms on the growth performance of waterfowl, the influence on nutrient digestion and absorption, and the relationship with the immune system.At the same time, the multiple factors affecting the intestinal microorganisms of waterfowl were analyzed from the four aspects of diet composition, physiological state of animals, external environmental factors, microbial factors and interactions, along with the prospect of future research ideas and development direction of gut microbes in waterfowl.In order to provide a theoretical basis for the design of feed formula, improving intestinal health and production efficiency in aquaculture, so as to accurately regulate the nutrition, immunity and growth process of waterfowl from the new target, intestinal microorganism, and support further in-depth study of intestinal microorganism of waterfowl.
