Resumo: | ABSTRACT: In this study, an outbreak of spontaneous poisoning by Dodonaea viscosa (D. viscosa) in a herd of dairy cattle in the municipality of Capão do Leão, Rio Grande do Sul, was investigated. Three deaths occurred in a batch of 16 Jersey cattle, aged between three and four years, kept in a native field. The clinical signs observed were apathy, decreased production, and anorexia, with death occurring within approximately 48 h after the onset of signs. The three cattle were necropsied, and tissue samples were sent for histopathological examination. Necropsy findings included serosanguineous fluid in the abdominal cavity, intestines with congested serosa, and marked mesenteric edema. The mucosa of the abomasum of two of the animals was hemorrhagic with bloody content, and among the ruminal content of a bovine, leaves with morphological characteristics compatible with D. viscosa were observed. The livers of the three animals were enlarged, with accentuation of the lobular pattern. Histologically, centrilobular coagulation necrosis with congestion and hemorrhage was observed in the liver. Vacuolization and degeneration of hepatocytes were observed in the mid-zonal and periportal regions. The diagnosis of poisoning by D. viscosa leaves was based on epidemiological data, necropsy findings, and histopathological alterations. The presence of the plant in the rumen and in the grazing site of the affected cattle was essential for the diagnosis. |
