| Summary: | There is an increasing interest in microbiota studies due to their relevance in physiological processes such as animal development and productivity. In addition, it its involved in the microbiota-intestine-brain axis that regulates the nervous system to the intestine and viceversa. This paper is aimed at identifying the importance of the broilers and laying hens’ gastrointestinal microbiota and its relationship with diverse physiological processes that intervene in the development, productivity, behavior, and health. There are 17 filos of bacteria within the poultry gastrointestinal tract, which are site dependent and have specific functions (Example; crop: Lactobacillus, Enterobacteriaceae; proventriculus: Clostridiaceae, Enterococcus; intestine: Escherichia, Streptococcus). In addition, different factors affect the development of microbiota such as the feeding program, handling, kind of substrate, stocking density, among others. There are several potentially pathogenic microorganisms that impact microbiota negatively and may reach the final consumer such as Campylobacter jejuni, Salmonella enteritidis and Escherichia coli. Therefore, it is important to continue supporting poultry microbiota research and areas of opportunity to improve poultry production. |
