肠道健康或肠道健康经常被讨论，但其含义没有任何明确的定义。建议将其定义为肠道完整性和功能性，因为两者都是肠道本身和宿主健康的先决条件。肠道的健康取决于肠道吸收能力的成功进化，这反过来又受到肠道免疫系统和微生物群共同进化的影响。营养供应在这一过程中起着重要作用，从微生物群的角度来看，随着年龄的增长，肠道和上胃肠道（GIT）微生物群在营养去除方面变得更加有效。饲料酶在这一过程中起着重要作用。植酸酶可以改善矿物质、氨基酸和能量的消化，从而减少肠道微生物对营养物质的利用。蛋白酶对氨基酸的供应也有类似的作用。非淀粉多糖酶（NSPases）具有独特的作用，因为它们不仅从宿主的角度改善饮食消化率，从而限制对微生物群的营养供应，而且它们还从不溶性基质释放可溶性纤维片段和/或将高分子量粘性纤维部分脱附成更小、更可发酵的碳水化合物部分。这导致可发酵碳水化合物与蛋白质供应之间的更有利的平衡，这一比例被认为是维持良好肠道健康的关键。如果无抗生素生产要成功，这种复杂进化的动态性质需要更多的考虑。版权所有© 2021作者。食品和农业科学杂志由John Wiley & Sons Ltd代表化学工业协会出版。
Gut health or intestinal health is frequently discussed without any clear definition as to its meaning. It is suggested that this should be defined as intestinal integrity and functionality as both are a pre‐requisite for the health of the intestine itself and the host. The health of the intestine is dependent upon a successful evolution of the absorptive capacity of the intestine, which in turn is influenced by the co‐evolution of the intestinal immune systems and the microbiota. Nutrient supply plays a significant role in this process and from the perspective of the microbiota this changes with age as the intestines and upper gastrointestinal tract (GIT) microbiota become more effective in nutrient removal. Feed enzymes play a significant role in this process. Phytases can improve digestion of minerals, amino acids and energy and as a result reduce the availability of nutrients in the lower intestines for the microbiota. Protease can have a similar effect with amino acid supply. Non‐starch polysaccharidases (NSPases) have a unique role in that they not only improve diet digestibility from the hosts perspective, thus limiting nutrient supply to the microbiota, but they also release soluble fragments of fibre from the insoluble matrix and/or depolymerize high molecular weight viscous fibre fractions in to smaller, more fermentable carbohydrate fractions. This results in a more favourable balance between fermentable carbohydrate to protein supply, a ratio which is deemed critical to maintaining good intestinal health. The dynamic nature of this complex evolution needs greater consideration if antibiotic free production is to succeed. © 2021 The Authors.
