Fifty-six goats died approximately 44 hours after been medicated with disophenol. Two animals were necropsied. Brown spots of approximately 2cm were observed in the capsule and cut surface of the liver. The cut surface of the kidneys presented clear areas mixed with dark areas. The urinary bladder was replete with urine and sediment. The abdominal, toracic and pericardic cavities had accumulation of yellow fluid. Edema was found in the trachea and lung. Metabolization of the coronary and mesenteric fat was also observed. Histologic lesions were characterized by centrilobular or diffuse necrosis of the liver; necrosis of the epitelial tubules, with presence of cilinders and congestion in the kidneys; and edema of the lung. Four goats were inoculated subcutaneously with 10, 10.5, 19.04 and 29.43mg per kg body weight of disophenol. The animal treated with 10.5mg/kg was mantained during 18 hours at room with temperature of 28ºC. The goat that recieved 29.43 mg/kg died. The macroscopic and histologic findings were similar to those observed in the spontaneous case.
