Cattle intoxication from Enterolobium contortisiliquum pods.

Three outbreaks of hepatogenous photosensitization caused by pods of Enterolobium contortisiliquum are reported in cattle. Clinical signs were anorexia, depression, photosensitization and abortion. Most affected cattle recovered in 30-40 d. At necropsies, liver was present, the gallbladder was enlarged and edematous, and numerous seeds of E contortisiliquum were in the forestomachs and abomasum. Fruits of the plants administrated to 2 calves produced clinical signs and 2/4 died. Clinical chemistry, gross necropsies and histopathology confirmed gastrointestinal irritation and liver degeneration. One calf dosed with only E contortisiliquum leaves did not develop clinical signs.
