Hypersensitivity to external stimuli, progressing in some animals to manic behaviour, occurred in a cattle herd that grazed a crop of field peas (Pisum sativumvar arvense) in the pre-flowering stage. Haematological and biochemical analyses eliminated hypomagnesaemia and ketosis as diagnoses. Other than two steers euthanased due to injuries sustained during manic episodes, all affected animals survived, recovering over 3 days when moved to alternative pasture. No necropsies were conducted. No microbial pathogens or endophytes were found on or in the plants. A previously reported incident in Victoria in 1987 in cattle grazing peas appeared to be of a similar nature. Environmental factors leading to these incidents were not clearly identified.
