Livestock industries strive to improve the health of their animals and, in the future, they are going to be required to do this with a continued reduction in antimicrobial use. Nutraceuticals represent a group of compounds that may help fill that void because they exert some health benefits when supplemented to livestock. This review is focused on the mechanisms of action, specifically related to the immune responses and health of ruminants. The nutraceutical classes discussed include probiotics, prebiotics, phytonutrients (essential oils and spices), and polyunsaturated fatty acids.
畜牧业致力于提高动物的健康水平，未来，随着抗菌药物使用的持续减少，它们将需要这样做。营养保健品是一类可能有助于填补这一空白的化合物，因为当它们被添加到牲畜饲料中时，会发挥一些健康益处。本综述重点介绍了作用机制，特别是与反刍动物的免疫反应和健康有关的机制。讨论的营养保健品类别包括益生菌、益生元、植物营养素（精油和香料）和多不饱和脂肪酸。
