What cardiac symptom has been observed in livestock like cattle after consuming *Ornithogalum*?
Answer
Cardiac irregularities
When livestock such as cattle, sheep, and horses ingest foliage or bulbs from *Ornithogalum* species, they can exhibit a range of adverse reactions. Among these noted symptoms are gastrointestinal distress, which manifests as colic and vomiting. Critically, the ingestion also causes cardiovascular disturbances, specifically identified as cardiac irregularities. This highlights the systemic impact of the plant's toxins, especially the cardiac glycosides found within, stressing that the danger extends beyond simple stomach upset to affect vital organ systems like the heart.
