Results and discussion

Effect levels
Key result
Dose descriptor:
LD50
Effect level:
> 3 200 - < 5 000 mg/kg bw
Based on:
test mat.
Mortality:
No mortality was observed at 2500 or 3200 mg/Kg. Seven of ten animals were found dead at 5000 mg/Kg.
Clinical signs:
other: Decreased activity, decreased muscle tone, abnormal gait, abnormal stance, discolored fur (green or yellow) and poor grooming were observed in the animals at 3200 and 5000 mg/Kg. Prostration was also observed at 5000 mg/Kg with loose stool and yellow stai
Other findings:
No visible lesions were observed in the surviving animals at terminal necropsy. Necropsy of animals found dead revealed distended stomachs, red lesions in the stomachs, and fluid-filled red intestines.
