Bryophyllum pinnatum poisoning of cattle

Two adult cattle died within 48 h of being fed a large amount of Bryophyllum pinnatum plants collected from a house garden. Clinical signs became apparent the day after feeding and included hypersalivation, ataxia, severe cardiac arrhythmia and laboured respiration. The main necropsy findings were acute rumenitis, reduction of bronchiolar lumens and emphysema.
