SUMMARY Naturally occurring cases of poisoning of cattle by Cestrum parqui were characterised by ataxia, depression, recumbency, convulsions and death. Three cattle were dosed experimentally by intrarumenal administration of fresh plant material. One calf died 48 h after receiving 30 g (wet weight) of plant /kg body weight. Doses of 11 and 17 g/kg caused only mild intoxication, with dullness and anorexia lasting 2 days. In natural and experimental cases the main lesion was hepatic periacinar necrosis. Elevated levels of plasma aspartate transaminase and prolonged prothrombin times were demonstrated in experimental cases. Haemorrhage beneath the serosa and into the intestinal lumen occurred in field cases, but not in the experimental. It is concluded that C. parqui poisoning in cattle is a primary hepatotoxicity.
