Vet Clin North Am Food Anim Pract. 2020 Nov;36(3):661-671. doi: 10.1016/j.cvfa.2020.08.001.

Abstract

Poisonous plant intoxication is one of the first considerations for various livestock diseases and unexplained animal deaths. Although toxic plants commonly poison livestock, obtaining a definitive diagnosis is difficult and challenging. This article provides a framework to help livestock producers, veterinarians, and diagnosticians reach the most accurate and definitive diagnosis. For this discussion poisoning caused by plants containing dehydropyrrolizidine alkaloids is used to provide examples and suggestions for investigating and sampling. It is also used to show how to recruit expert collaborators, diagnostic resources, and information sources to amass required expertise, information, and laboratory results to produce the best diagnosis.
