Abstract

The gut microbiota of poultry primarily arises from environmental factors influenced by farm management practices, including diet composition, litter management, and hygiene. The use of feed additives can also affect the formation and alteration of gut microbiota composition. Moreover, welfare-related factors in both conventional and alternative poultry systems, such as stocking density and access to outdoor areas, significantly impact the structure and diversity of gut microbiota. These changes can influence bird health and the birds' resistance to intestinal pathogens and diseases. Early intervention strategies, such as dietary changes and feed additives, are considered effective tools to improve gut health in poultry. These interventions can guide the development of gut microbiota towards a more resilient state against pathogen colonization. Furthermore, optimizing the birds’ living conditions by reducing environmental stressors can significantly enhance immune system efficiency and overall bird health.
