Abstract

Dietary fibers (DF) largely represent carbohydrate polymers of plant origin which are able to escape endogenous enzymatic digestion in the small intestine of non-ruminant hosts like poultry. Traditionally, DF was considered as nutrient diluent, and as an anti-nutritional factor. Dietary fibers, however, have been shown to positively influence digestive system, immune function, microbiota, and also poultry behavior. After the ban of antibiotics and antibiotic growth promoters in many countries, nutritional strategies to meet the genetic potential of poultry breeds have been extensively investigated. Furthermore, increase use of unconventional or alternative feed resources to reduce the feed cost and human food competition have made the DF topic more interesting as such products are generally rich in fiber; therefore can alter the poultry performance. Thus, to produce poultry sustainably and eco-friendly, DF has to be carefully managed in poultry which further requires sound knowledge on feed formulation, source of fiber, type, subtype, form, inclusion rate, and other managerial aspects like exogenous enzyme supplementation. To sum up, this review paper has critically analyzed the dietary fiber related issues including posi-tive and negative sides of DF in modern day’s poultry nutrition. Finally, gaps in previous researches have been also identified and future direction has been suggested to better understand the topic considering therapeutic role of DF in poultry health.

家禽营养中膳食纤维研究的过去、现在和未来展望
膳食纤维(DF)主要是植物来源的碳水化合物聚合物,能够在非反刍动物宿主(如家禽)的小肠中逃脱内源性酶消化。传统上,DF被认为是营养稀释剂和抗营养因子。然而,膳食纤维已被证明对消化系统、免疫功能、微生物群和家禽行为有积极影响。在许多国家禁止抗生素和抗生素生长促进剂之后,人们广泛研究了满足家禽品种遗传潜力的营养策略。此外,人们越来越多地使用非常规或替代饲料资源,以降低饲料成本和人类食品竞争,这使得DF话题更加有趣,因为这类产品通常富含纤维;因此可以改变家禽的生产性能。因此,为了可持续和环保地生产家禽,必须对家禽中的DF进行仔细管理,这进一步需要对饲料配方、纤维来源、类型、亚型、形式、包含率以及外源性酶补充等其他管理方面有充分的了解。综上所述,本文批判性地分析了膳食纤维相关问题,包括DF在现代家禽营养中的积极和消极方面。最后,还确定了以往研究中的空白,并提出了未来的方向,以更好地理解考虑DF在家禽健康中的治疗作用的主题。
