Abstract: The gastrointestinal tract (GIT) and the community of intestinal microorganisms play a crucial role in the health and functioning of birds, influencing nutrient absorption, strengthening the immune system, and protecting against diseases. Changes in the composition of this microbial community can negatively impact food efficiency, productivity, and bird welfare. The gastrointestinal compartments of birds are inhabited by complex bacterial communities, which recent studies have recognized as having fundamental roles in bird nutrition, physiology, and intestinal development. The intestinal microbiota can act as a protective barrier, adhering to the intestinal epithelial walls and reducing colonization by pathogenic bacteria. These bacteria produce beneficial compounds such as vitamins, short-chain fatty acids, and antimicrobial compounds, which provide nutrition and protection to the animal. However, the intestinal microbiome can also serve as a source of bacterial pathogens, posing a threat to public health. A healthy intestinal microbiota brings significant benefits, including effective competition against pathogens, immune system development, and the creation of protective barriers against undesirable microorganisms. On the other hand, the commensal microbiota also presents challenges, such as competition for energy and proteins in the proximal intestine and the generation of harmful metabolites. Despite the benefits, these processes increase the demand for energy and protein from the host, impacting bird growth performance. In summary, understanding and managing the intestinal microbiota is fundamental to sustainably promoting birds' health and productivity. This study aims to analyze the influence of the intestinal microbiome on commercial poultry health and production, focusing on its effects on the immune system, digestion, and disease resistance.
