The importance of gut microbiota in chickens with particular emphasis on the field situation

Intestinal systems of living organisms are inhabited by a dense community of microorganisms dominated by bacteria but also containing archaea, fungi, protozoa and viruses. The microorganisms within these communities exist in a symbiotic relationship with the host and are collectively known as microbiota. Recent expansion in knowledge about the influence of microbiota on health and disease started a major research revolution in the area. In poultry research, a number of ground-breaking publications have significantly expanded our knowledge and understanding of poultry health. In this mini-review, we focus on poultry gut health issues and propose solutions for improving birds' health by refining their intestinal microbiota health and stability.
