Poisonous plants affect livestock and wildlife and in addition to animal disease, they often inhibit the productive use of feeds and natural resources. For some plants, intermittent or cyclic grazing may allow the use of contaminated forages or infested pastures or ranges while avoiding permanent effects of poisoning. The objective of this review is to present several toxic plants for which intermittent poisoning might be an effective management tool. Additionally, as intermittent exposures present risks, those risks will be discussed, and signs of impending problems identified. Additional plants that mechanistically have potential for becoming less problematic via intermittent exposure will also be discussed. Lastly, toxic plants to which any exposure causes permanent or fatal damage or those that might result in cumulative damage with repeated exposures will also be discussed.
有毒植物会影响家畜和野生动物，除了引发动物疾病外，它们还常常抑制饲料和自然资源的生产性利用。对于一些植物来说，间歇性或周期性放牧或许能使受污染的草料或受侵染的牧场得以利用，同时避免中毒的永久性影响。本综述的目的是介绍几种间歇性中毒可能是有效管理手段的有毒植物。此外，由于间歇性接触存在风险，将对这些风险进行讨论，并识别即将出现问题的迹象。还将讨论其他一些从机制上讲通过间歇性接触可能会减少问题的植物。最后，还将讨论任何接触都会导致永久性或致命损害的有毒植物，以及那些反复接触可能会造成累积损害的有毒植物。
