Abstract：The intestine serves as a vital immune barrier organ in poultry.During the growth and development of poultry,diverse microorganisms colonize the gut and form complex communities.These microorganisms include both potential pathogens such as Escherichia coli and Salmonella,and beneficial bacteria such as Lactobacilli.Different microbial communities constrain each other,collectively maintaining a relatively stable intestinal microecology.This microecology plays a crucial role in preserving intestinal barrier integrity,regulating immune function,and resisting pathogen invasion.A deeper understanding of the colonization and succession patterns of intestinal microorganisms in poultry will aid in developing more targeted microecology regulation strategies.This article reviews the research progress on intestinal microbial colonization,microorganisms balance and dysbiosis,and their physiological functions,aiming to provide references for subsequent research on regulating poultry intestinal microorganisms,as well as for improving poultry intestinal microecology,enhancing intestinal mucosal immunity,and advancing healthy farming practices.
