Abstract: The gastrointestinal tract houses a large and diverse microbiota,and these microbiota play an important role in growth and health of chickens,contributing to feed digestion and nutrient absorption,development of the intestinal villus and crypt morphology,and improvement of the hosts’ immune systems. Understanding the spatial and temporal variability of gut microbiota and early bacterial colonization will help to develop new microbiota-based intervention strategies in poultry production. This review discusses the composition and successional development of chicken intestinal microbiota,and early microbiota establishment,and summarizes the latest progresses.

Key words: intestinal microbiota, successional development, early bacterial colonization, chicken
