Apart from the obvious role of plants in herbivore nutrition, they are also a rich source of bioactive products that can operate either to the benefit or the detriment of grazing animals. Here, we review the available evidence for the potential beneficial effects that plant-derived bioactive substances can have on gastrointestinal parasites. Tannin-rich plants have attracted most attention for their effect on internal nematodes in ruminants. These plants could act through direct antiparasitic activity but might also act indirectly by increasing host resistance. The effects vary with the species of plant, parasite and host. More research is required to understand better the mechanisms of action, and therefore make more pertinent use of these bioactive plants in livestock systems.
除了植物在食草动物营养方面的明显作用外，它们还是生物活性产物的丰富来源，这些产物可能对放牧动物有益，也可能有害。在此，我们综述了植物源生物活性物质对胃肠道寄生虫可能产生的有益影响的现有证据。富含单宁的植物因其对反刍动物体内线虫的作用而备受关注。这些植物可能通过直接的抗寄生虫活性起作用，但也可能通过增强宿主抵抗力间接起作用。其效果因植物、寄生虫和宿主的种类而异。需要更多研究来更好地理解其作用机制，从而在畜牧系统中更恰当地利用这些生物活性植物。
