Many toxic plants, ingested by livestock while grazing or eating contaminated processed feed, produce myoskeletal or myocardial lesions that sometimes have irreversible consequences. Some myotoxic plants are lethal after ingestion of very small amounts whereas others require consumption for many days to several weeks to produce disease. Incorporation of field studies, clinical signs, gross and microscopic pathology, and chemical identification of plants, toxins, and metabolites in animal samples is essential for an accurate diagnosis. This review introduces toxic plants that cause myotoxicity, reviews toxins and lesions, discusses analyses for making an accurate diagnosis, and summarizes treatments and recommendations to avoid future poisonings.
