膳食纤维与营养利用受损和净能值降低有关。然而，膳食中必须包含纤维，以维持消化道的正常生理功能。此外，膳食纤维的负面影响将取决于纤维的性质，并且在纤维来源之间可能有很大差异。可采用多种技术提高饲料的营养价值，提高可利用饲料资源的利用率。此外，纤维的利用程度受猪的年龄和猪的品种的影响。利用膳食纤维潜在的益生元效应是一种有吸引力的方式来刺激肠道健康，从而最大限度地减少使用抗微生物生长促进剂。饲粮中添加可溶性非淀粉多糖（NSP）可促进共生肠道微生物的生长。菊苣中添加NSP会改变猪的肠道微环境和肠道形态，但生长性能不受影响，消化率仅略微降低。发酵产物和食糜pH值随日粮类型的变化而变化，并与菌群的变化相关。有趣的是，纤维摄入量会影响猪肠上皮热休克蛋白的表达。热休克蛋白在肠道中具有重要的生理作用，并在维持粘膜屏障完整性方面具有重要的内护功能。因此，越来越多的证据表明，由于纤维与肠道微环境和肠道相关免疫系统的相互作用，纤维可以对猪产生益生元效应。
Dietary fiber is associated with impaired nutrient utilization and reduced net energy values. However, fiber has to be included in the diet to maintain normal physiological functions in the digestive tract. Moreover, the negative impact of dietary fiber will be determined by the fiber properties and may differ considerably between fiber sources. Various techniques can be applied to enhance nutritional value and utilization of available feed resources. In addition, the extent of fiber utilization is affected by the age of the pig and the pig breed. The use of potential prebiotic effects of dietary fiber is an attractive way to stimulate gut health and thereby minimize the use of anti-microbial growth promoters. Inclusion of soluble non-starch polysaccharides (NSP) in the diet can stimulate the growth of commensal gut microbes. Inclusion of NSP from chicory results in changes in gut micro-environment and gut morphology of pigs, while growth performance remains unaffected and digestibility was only marginally reduced. The fermentation products and pH in digesta responded to diet type and were correlated with shifts in the microbiota. Interestingly, fiber intake will have an impact on the expression of intestinal epithelial heat-shock proteins in the pig. Heat-shock proteins have an important physiological role in the gut and carry out crucial housekeeping functions in order to maintain the mucosal barrier integrity. Thus, there are increasing evidence showing that fiber can have prebiotic effects in pigs due to interactions with the gut micro-environment and the gut associated immune system.
