The interactions of the gut microbial populations and how this impacts poultry gut health and ultimately poultry production is rapidly emerging as a critical component. There are several contributors to gut microbial ecology including not only the members of the gut microbial community but their resulting metabolic activities and interactions with host systems. Consequently, it is not just a matter of microbial composition but the metabolic functions of these individual microorganisms as members of a complex highly interactive community. In this symposium evidence of these interactions and their impact on the host will be presented. The development and expansion of the gut microbial community as the young bird matures can interface with host systems such as the immune response resulting in an interconnected relationship between these two entities. This is also true for the gut microorganisms themselves as the opportunities for metabolic “crosstalk” are common with the end products generated by certain members of the gut microbiota serving as substrates for other members. Finally, it is possible to edit or change the microbiota and/or metabolic activities optimizing this interactive balance for host benefit by supplementing feed additives such as prebiotics or organic acids. Therefore, the presence of pathogens, corresponding responses of host systems, the microbial community fermentation, and external dietary additives can influence the microbial metabolome, the host, pathogen biology, poultry nutrition, and gut health.
Take home points:
Regardless of the contributions of each of individual host and gut microbial factor, all circle back to the gut microbiota being a primary impact agent for what can go right or wrong with overall poultry gut health.
This symposium aims to not only identify the key components of these gut microbial-host interactions but demonstrate the inter-related connections among them.
Understanding these complex interactions and identifying the “cause and effect nature” impact on the gut microbiota represents a tremendous opportunity to strategically improve poultry gut health.
