Abstract: The balance of intestinal flora is closely related to the health and growth of animals.As a green and safe functional feed additive,organic acid (OA) has the effects of bacteriostasis,promoting digestion and regulating flora balance.With the continuous development of feed industry,OA has been gradually transformed from feed acidification,anticorrosion and mildew prevention to preparation,animal growth enhancers and anti-resistant products,and has become a functional additive widely used in the animal husbandry industry.The author reviewed the formation and distribution of pig intestinal flora,the effects of OA on the composition and diversity of pig intestinal flora,the production of metabolites and intestinal immune response,and the mechanism of regulating pig intestinal flora was discussed in order to further reveal the interaction mechanism between OA and intestinal flora,and provide reference for promoting pig intestinal health and rational utilization of OA.
