The intestinal microbiota has gained increased attention from researchers within the swine industry due to its role in promoting intestinal maturation,immune system modulation,and consequently the enhancement of the health and growth performance of the host.This review aimed to provide updated scientific information on the interaction among intestinal microbiota,dietary components,and intestinal health of pigs.The small intestine is a key site to evaluate the interaction of the microbiota,diet,and host because it is the main site for digestion and absorption of nutrients and plays an important role within the immune system.The diet and its associated components such as feed additives are the main factors affecting the microbial composition and is central in stimulating a beneficial population of microbiota.The microbiota-host interaction modulates the immune system,and,concurrently,the immune system helps to modulate the microbiota composition.The direct interaction between the microbiota and the host is an indication that the mucosa-associated microbiota can be more effective in evaluating its effect on health parameters.It was demonstrated that the mucosa-associated microbiota should be evaluated when analyzing the interaction among diets,microbiota,and health.In addition,supplementation of feed additives aimed to promote the intestinal health of pigs should consider their roles in the modu-lation of mucosa-associated microbiota as biomarkers to predict the response of growth performance to dietary interventions.
