The intestine harbors a community of bacteria that is intestinal microbiota, which is a complex and highly diverse community. This review discusses the gut microbiota in piglets, including the role of intestinal homeostasis in maintaining piglet health and the various factors that influence gut microbiota. Nutritional interventions, particularly the supplementation of plant-derived polysaccharides, including dietary fiber, for weaned piglets have been shown to enhance the abundance and colonization of beneficial intestinal microbes, reduce the incidence of gastrointestinal infections, and decrease the frequency of diarrhea, thereby improving gut health and growth performance. In this context, various polysaccharides, such as those derived from L. (alfalfa), Fisch. (licorice), and L. (wolfberry), C.A. Mey. (ginseng), and (Fisch.) Bunge (astragalus) has demonstrated significant success. Additionally, dietary fibers such as inulin, pectin, beta-glucans, gums, cellulose, resistant starch, and starch derivatives have shown potential in regulating the gastrointestinal microbiota. Research has also explored the correlation between the structural characteristics of dietary polysaccharides and their biological activities. This review will pave the way for the development and utilization of plant-derived polysaccharides as effective non-antibiotic alternatives to restore gut microbial balance in weaning piglets.
肠道中栖息着一群细菌，即肠道微生物群，这是一个复杂且高度多样化的群落。本综述讨论了仔猪的肠道微生物群，包括肠道稳态在维持仔猪健康中的作用以及影响肠道微生物群的各种因素。营养干预措施，特别是对断奶仔猪补充植物源多糖（包括膳食纤维），已被证明可以提高有益肠道微生物的丰度和定殖，降低胃肠道感染的发生率，并减少腹泻频率，从而改善肠道健康和生长性能。在这方面，各种多糖，如来自紫花苜蓿、甘草、枸杞、人参和黄芪的多糖已取得显著成效。此外，菊粉、果胶、β-葡聚糖、树胶、纤维素、抗性淀粉和淀粉衍生物等膳食纤维在调节胃肠道微生物群方面也显示出潜力。研究还探讨了膳食多糖的结构特征与其生物活性之间的相关性。本综述将为开发和利用植物源多糖作为有效的非抗生素替代品来恢复断奶仔猪肠道微生物平衡铺平道路。
