Despite its negative impact on performances because of lower protein and energy digestibility, increasing attention has been paid in the past decade to dietary fibre in swine nutrition due to its multiple functionalities. The present review examines the influence of dietary fibre on the digestive processes and the consequences on pig protein and energy nutrition, health concerns and environmental issues. Dietary fibre is defined as the plant polysaccharides that are resistant to digestive secretions and are potentially available for bacterial fermentation in the intestines of single-stomached animals. Resistant starch is also considered as a dietary fibre. The short-chain fatty acids released by bacteria contribute to the host energy supply and both regulate the composition of the flora and the growth of epithelial cells, especially in the case of butyrate. The bacterial growth supported by the fermentation induces a shift of N excretion from urine to faeces. Beside the fermentability, the physical properties of dietary fibre such as the water-holding capacity, the viscosity and the solubility influence the digestion, the satiety and the transit time. In relationship with the mechanisms of dietary fibre interaction with the digestive processes exposed in this review, the opportunities and treats of dietary fibre inclusion in swine rations for intensified and for more extensive tropical production systems are discussed. Dietary fibre is indeed a possible means to reduce nitrogen losses of production units and to improve pig intestinal health and animal welfare. Finally, the potential role of in vitro fermentation methods to investigate the fate of dietary fibre in the digestive system is discussed.
