The gut microbes of monogastric animals such as pigs are composed of bacteria, fungi, archaea and viruses, and the proportion of fungi in gut microbes is less than 1%, which has been overlooked in previous studies. However, recent studies have shown that intestinal fungi are closely related to the maintenance of host intestinal barrier function, intestinal immune response, and post-intestinal microbial fermentation. Moreover, the volume of a single fungal cell is about 100 times that of a single bacterial cell, and can encode a large number of functional enzymes, which can affect host nutrient metabolism and body health to a certain extent. Therefore, fungi are an important member of gut microbiome of monogastric animals that cannot be ignored. Yet, to date, there is still a lack of research on intestinal fungi in monogastric animals such as pigs, which limits our understanding of the overall function of the gut microbiome. In this paper, the composition, influencing factors, and effects of intestinal fungi in swine gut on host health and nutrient digestion and absorption were comprehensively reviewed, providing ideas for further understanding its biological functions.
