This review provides an overview of the current research on prebiotics and their applications in animal nutrition and health. Various types of prebiotics are introduced and classified, with an analysis of agro-industrial residues as sources. The potential of prebiotics as substrates for the growth and/or activity of probiotic microorganisms, as well as their applications in animal feeds, were examined. This analysis also considered the health-promoting advantages linked to different production techniques and bioactive compounds. The mechanisms by which prebiotics alter gastrointestinal tract microbiota are discussed, specifically in terms of combating pathogenic bacteria and modulating immune cells in the gut. Investigations of the impact of prebiotics in both polygastric and monogastric animals are reported, highlighting their effects on the gut ecosystem and animal performance. This review concludes that agro-industrial residues are valuable sources of prebiotics that possess numerous beneficial health-promoting properties suitable for animal nutrition. These prebiotics can serve as a relevant substitute in the ongoing search for alternative strategies to prevent and control the presence of pathogenic bacteria in animals, particularly considering the restriction on antimicrobial growth promoters. However, further research is necessary to explore the interaction between prebiotics and probiotics in animal care and well-being, to establish systematic management of production and practical applications of these functional feed additives.
本综述概述了目前关于益生元及其在动物营养与健康方面应用的研究。介绍并分类了各种类型的益生元，分析了以农业工业残渣作为来源的情况。研究了益生元作为益生菌微生物生长和/或活性底物的潜力，以及它们在动物饲料中的应用。该分析还考虑了与不同生产技术和生物活性化合物相关的促进健康的优势。讨论了益生元改变胃肠道微生物群的机制，特别是在对抗病原菌和调节肠道免疫细胞方面。报告了对益生元在多胃动物和单胃动物中影响的研究，突出了它们对肠道生态系统和动物性能的影响。本综述得出结论，农业工业残渣是益生元的宝贵来源，具有许多适合动物营养的有益健康促进特性。这些益生元可以作为一种相关替代品，用于正在进行的寻找预防和控制动物病原菌存在的替代策略，特别是考虑到对抗菌生长促进剂的限制。然而，有必要进一步研究益生元和益生菌在动物护理和健康方面的相互作用，以建立这些功能性饲料添加剂生产和实际应用的系统管理。
