Abstract

ABSTRACT: This study reports four outbreaks of Cestrum axillare poisoning in cattle. Outbreaks occurred in farms of the Distrito Federal, Goiás, and Minas Gerais states during the dry season, affecting cows and heifers, with a mortality rate of 1 to 14,28%. Poisoned animals showed neurological signs and recumbency, followed by death within 12 hours, and some animals were found dead. Gross and histological lesions were typical of acute hepatotoxicity with hepatomegaly, enhancement of lobular pattern, and centrilobular to massive necrosis. This study seems to be the first report on C. axillare poisoning in cattle in the Distrito Federal, Goiás, and Triângulo Mineiro. C. axillare poisoning must be included in the differential diagnosis for cattle with hepatic necrosis in these locations.
