A stable and diverse microbiota is essential for health and digestion

In the neonatal piglet, the microbiota induces several aspects of postnatal development, including the development of the gut immune system. Successional development of microbes occurs during the first weeks, when the colonization of the pig gut is greatly influenced by the immediate environment, including the diet. During this period and especially before weaning, management and nutrition needs to focus on reducing the disruption of the microbiological ecosystem of the young developing gut to achieve a diverse and stable microbiota affecting health and digestion in later life.
