动物饲料中的益生菌和益生元
摘要
In livestock production, probiotics have become highly recognied as supplements for animals because of their beneficial outcome on health improvement and well-being maintenance. Several studies are contributing to the better understanding of the impact of probiotics and prebiotics on the modulation of the intestinal microbiota and their subsequent effects on the host health. Several factors, encompassing dietary and management constraints, have been demonstrated to tremendously influence the structure, composition, and activities of gut microbial communities in farm animals. Under stressing surroundings, the direct-fed microbes and feed ingredients may play a key role as the salient limiting factor of the severity of the dysbiosis caused by disruption of the normal intestinal homeostasis. Probiotics are live microorganisms; prebiotics as nondigestible feed components may confer health benefits on the host by positively modifying the intestinal microflora. This work discusses defin

在牲畜生产中,由于其有益的结果对健康改善和良好维护,益生菌对动物的补充剂感到高度认可。几项研究有助于更好地了解益生菌和益生元对肠道微生物的调节的影响及其随后对宿主健康影响的影响。已经证明了几种因素,包括饮食和管理限制,以极大地影响农场动物肠道微生物社区的结构,组成和活性。在强调周围环境下,直接喂养的微生物和饲料成分可能发挥关键作用,作为由于正常肠道稳态的破坏引起的消化不良引起的严重程度的突出限制因素。益生菌是活的微生物;益生元作为非易生的饲料组分可以通过积极改性肠道微氯来赋予宿主的健康益处。这项工作讨论了益生菌和益生元的定义。还提出了这些类型的配方必须满足的标准。在益生菌和益生菌菌株的主要选择标准和饲料成分的主要选择性标准和要求中也逐渐讨论了动物饲养的益生菌和益生菌的商业市场。本章提供最常用的益生菌和益生菌列表,以及用于动物营养的公式和制剂的一些有关的例子。还概述了可用研究结果对益生菌和益生元对动物性能参数和福利的影响。
