The intestinal microbes do not only provide nutrients for their host, but it also contributes to the maintenance of intestinal micro ecological balance, which are essential for ensuring a healthy development of the intestine, dietary fiber is one of the substrates for intestinal microbial fermentation. This can improve the structure of intestinal microflora and is of great significance in maintaining intestinal health. The research on the efficacy of dietary fiber on pig intestinal microbes and the factors affecting the intestinal microbial utilization of dietary fibre in pigs is reviewed, which provides a theoretical basis for further research on the production practice of dietary fiber addition in pig breeding industry. As well, a good digestive physiological environment is essential for pigs to benefit from the nutrients and to increase their productivity. Adding the appropriate amounts of fiber to pig diets plays an important role in regulating the digestive physiology of pig intestinal microflora, digestive tract pH, digestive juice secretion, digestive enzyme activity, digestive tract organs and their morphology. This article reviews the effects of dietary fiber on the digestive physiology of pigs.
